    Theresa Badurek, Urban Horticulture Extension AgentAgapanthus(Photo-UF/IFAS)In the fall the weather will begin to cool and the rains will slow down.  (Hard to imagine these days, isn't it?) These conditions present several challenges for the home gardener, but there are some things you can do to prepare your garden (and yourself) for the cooler, drier weather.If you use annualsin your landscape it may be time to replace some of the summer annuals.  In early fall (Sept.-Oct.) try plants like ageratum, coleus, celosia, zinnia, and wax begonia to give your landscape color into cooler weather.  Then once temperatures start to cool (Oct.-Nov.) you can plat petunia, pansy, snapdragon, dianthus, and alyssum.  When shopping for annuals choose compact plants with healthy leaves, good color, and lots of flower buds (they don’t have to be in bloom at the time of purchase).  For more information about gardening with annuals in Florida: http://edis.ifas.ufl.edu/pdffiles/MG/MG31900.pdf.  Since annuals are seasonal they should make up focal areas in the garden, but not too much space, as they require a lot of energy and resources for such a short life-span.   Lots of bulbs like to get their start in these cooler months.  Plant agapanthus, amaryllis, and lilies now for blooms next spring and summer.  Divide and replant perennials and bulbs that have grown too large- be sure to do this by November so they can become established before the weather turns colder.  Add organic matter to new planting areas and monitor water needs during establishment.  For more information about dividing and propagating plants: http://edis.ifas.ufl.edu/mg108.Cilantro (Photo-Iowa State University Extension)Plant herbs that tolerate the warm temperatures of early fall, such as Mexican tarragon, mint, rosemary, and basil.  Later in the fall when the weather is cooler try parsley, cilantro, garlic, and thyme.  Since some herbs are annuals and some are perennials remember to group them accordingly so you won’t be disturbing the perennials when replanting the annuals.  Many herbs are also suited to planting in containers- but you must remember that those plants in containers will dry out faster than those in the ground and will need more irrigation attention.  For more information about growing herbs in your Florida garden: http://edis.ifas.ufl.edu/pdffiles/VH/VH02000.pdf. Cabbage (Photo-Purdue)In this cooler weather (Oct.-Nov.) you can plant cool-season vegetablecrops, such as celery, cabbage, lettuce, collards, and many others.  For more information about vegetable gardening in Florida, including suggested crops and their planting dates: http://edis.ifas.ufl.edu/pdffiles/VH/VH02100.pdf.  In September or October, fertilize your citrus with a balanced fertilizer.  Many early season citrus varieties will be ready for harvest starting in October and November, such as ‘Navel’ and ‘Hamlin’ oranges, ‘Marsh’ grapefruit, ‘Orlando’ tangelos, ‘Meyer’ lemons, and more.  If necessary, fertilize your St. Augustinegrass and bahiagrass lawns with a fertilizer containing at least 50% slow-release nitrogen and no phosphorous in early October.  Do not use a “weed and feed” product.  No lawn and landscape fertilizer containing nitrogen can be used in Pinellas County before October 1st.  (For more info on the Pinellas County Fertilizer ordinance: http://www.pinellascounty.org/PDF/Fertilizer-Ordinance-Brochure.pdf.)  As the weather gets cooler the turf will not need as many nutrients so this is best applied in early October. Enjoy planning for this cooler season soon to come!

    You Could Have it Made in the Shade

    During the summer when the heat is stifling, it’s important to take advantage of shade when you are outdoors.  If your yard has no shade trees you may not have much respite from the heat. Shade on your home and air conditioner may also decrease your energy costs in the summer.  With all of these benefits you may be considering planting shade trees on your property.  Planting a tree is a (hopefully) long-term commitment so you want to choose the right tree from the start.  If you choose an evergreen tree you will have shade year-round while deciduous trees will shade your house in summer but allow the sun to warm your house in winter when they lose their leaves.  You can plant shade trees at any time of year; just be sure to follow UF recommendations for proper planting practices.   To learn more about these practices visit Planting and Establishing Trees at http://edis.ifas.ufl.edu/pdffiles/EP/EP31400.pdf. Pinellas County is unique in several ways- most of us have smaller lots to work with, some have salt breezes from the water to contend with, and we all have wind storms.  You may be wondering what shade trees can we plant here that will thrive in our unique environment?  A favorite shade tree in our county is the Live Oak, Quercus virginiana (large tree, zones 8-11).  Live oak is a great choice but grows very large- up to 40 to 60 feet in height with a 60 to 100 foot spread.  It is drought and salt tolerant as well as wind resistant, which is why it’s a popular choice if you have the room. Sparkleberry, Vaccineum arboreumSweetgum, Liquidambar styracifluaIf you have a moist but well-drained site and space you could consider Sweetgum, Liquidambar styraciflua (large tree, zones 5b-10a) or Sparkleberry, Vaccinium arboreum (small tree, zones 7-10).  These two choices are deciduous, so they will lose their leaves in winter when you would probably prefer more sun anyway.  Their leaves also turn beautiful colors before they fall bringing seasonal color to your landscape.  Sparkleberry has high wind resistance and sweetgum is considered to have medium-high wind resistance.  Sparkleberry also flowers profusely if grown in full sun.Silver variety of Buttonwood, Conocarpus erectusFor smaller property with drier conditions you might consider the following small trees, all of which are salt and drought tolerant and have high wind resistance: Buttonwood, Conocarpus erectus (small tree, zones 10a-11), Simpson’s Stopper, Myrcianthes fragrans (small tree, zones 9-11), and Yaupon Holly, Ilex vomitoria (small tree, zones 7-10).  These three choices are all evergreen and will provide year-round shade.  All three of these choices can be grown as a large shrub or a small tree.  Each of these have unique characteristics that take them beyond a simple shade tree: Buttonwood has a silver variety that has silvery leaves that shimmer in the sun and the wind, Simpson’s Stopper has reddish, flaking showy bark and Yaupon Holly produces beautiful red fruit in the fall and winter on the female plants (males must be present for fruit production). Yaupon Holly, Ilex VomitoriaYaupon Holly fruitThe right shade tree for you may not be on this short list, but remember to consider size, evergreen vs. deciduous, color, seasonal interest, and match growing conditions to your site conditions for the greatest chance of success.  For more guidance with this and other plant choices in your landscape please visit the interactive plant selector Florida-friendly Plant Database at http://floridayards.org/fyplants/.  For information on the health and maintenance of shade trees please visit: http://hort.ifas.ufl.edu/woody/maintenance.shtml.*Northern Pinellas County is in zone 9b, central and southern Pinellas County is zone 10a.

    It’s May and the weather is still pleasant… for now.  Soon we will be battling hot summer sun, bugs, humidity, and torrential rains every afternoon.  These conditions present several challenges for the home gardener, but there are things you can do now to prepare your garden (and yourself) for the heat.       Smart garden planning will give you more time to play here!  Photo courtesy Pinellas County.  If you use annuals in your landscape you probably know by now that many of them don’t tolerate the Florida heat very well.  Just because a plant is being sold in local garden centers does not necessarily mean it’s the right time to plant them here in Florida.  However, there are several annual plants that take our temps in stride.  They include salvia, torenia, wax begonia, coleus, and ornamental peppers. When shopping for annuals choose compact plants with healthy leaves, good color, and lots of flower buds (they don’t have to be in bloom at the time of purchase).  Click here for more information about gardening with annuals in Florida.Coleus, photo courtesy UF/IFAS Okeechobee County  Since annuals are seasonal they should make up focal areas in the garden, but not too much space, as they require a lot of energy and resources for such a short life-span.   Right now is also a great time to plan new perennial plantings, including trees, palms, shrubs, and groundcovers.  If you have a plan at the ready you can be prepared to install once the rainy season starts- then you won’t need to water as often yourself.  Just remember that if you plant something before you go on vacation you should ask a friend or neighbor to care for it while you are gone.   Click here for more information on establishing new trees and shrubs. But that’s not all you can do this time of the year.  You can also plant some herbs that like the heat such as basil, Mexican tarragon, and rosemary.  Since some herbs are annuals and some are perennials remember to group them accordingly so you won’t be disturbing the perennials when replanting the annuals.  Many herbs are also suited to planting in containers- but you must remember that those plants in containers will dry out faster than those in the ground and will need more irrigation attention.  Click here for more information about growing herbs in your Florida garden.  Southern peas, aka black-eye peas, courtesy UF/IFAS ExtensionIf you think your new herbs might get lonely out there, don’t hesitate to try your hand at vegetable gardening.  But (and this is a biggie) you can’t plant the same veggies in the summer that you can up north.  Our hot temps just won’t work with many of the usual veggies, but there are several crops you can grow here in the heat including okra, southern pea, and sweet potato.  Click here for more information about vegetable gardening in Florida, including suggested crops and their planting dates.  Summer (June, July and August are great) is also a good time to solarize your vegetable garden, so you can add this to your summer gardening plan.  What does that mean?  Well, this one prep can help reduce soil pests and even kill weed seeds, making your garden more successful throughout the fall gardening season.  Solarizing involves harnessing the heat of the sun by covering the soil with clear plastic and is most effective in the summer months.  To solarize, you want to prepare your soil with any amendments such as compost or manures before you begin.  Make sure your garden is clear of rocks, twigs, weeds, and other debris.  Till the soil to at least 6 inches to make sure the heat will penetrate deeply enough to be effective.   The day after a good rain or irrigation is best for applying the clear plastic sheeting over the soil.  Lay sheets of clear plastic over the soil and bury the edges to keep it in place.  Clear plastic is the only kind that will be effective- do not use black.  Finally, leave plastic in place for at least 6 weeks.  Click here for more info on solarizing your garden,visit “Introduction to Soil Solarization”. Photo from UF/IFAS "Trees and Hurricanes" websiteA discussion of summer garden preps wouldn’t be complete without a mention of hurricane season.  Now is your last chance to prepare for hurricane season by checking trees for damaged or weak branches and prune if needed.  Be sure to hire an ISA (International Society of Arboriculture) certified arborist to do this work- they are trained to care for trees and continually participate in ongoing education to maintain this certification.  This can help lengthen the life of your trees and minimize the chance of property damage.  To find a certified arborist near you, visit the ISA website tool to locate a tree professional by clicking here.   Last, but definitely not least, make sure to watch out for your own health in the heat.  Slow down, dress for summer, do not get too much sun, drink water, do not drink alcoholic beverages, and spend more time in air-conditioned places.  The University of Florida Extension has a great webpage for heat safety that everyone should read before it gets too hot, visit it by clicking here.  Be safe and have a great summer!

InsectsThere are thousands of insects in Florida, and knowing whether the one you found is harmless, beneficial, or damaging is key for deciding on control measures. The Insect ID Lab can analyze insect samples sent by Florida residents. The Help Desk can provide answers or information on preparing a sample to send to the Insect ID Lab. The lab will charge $8 per sample sent.Send samples in a crush-proof container with the accompanying submission form (205KB pdf). Sending samples in flat or padded envelopes is discouraged.Collecting a Sample1)    The more specimens included in a sample, the better. 2)    In most cases, you should kill and preserve the insects before sending them. a.    Do this by placing them in the freezer or in a vial with rubbing alcohol.                                          i.    Caterpillars will not preserve well in an alcohol solution.

All identification samples sent to the herbarium must first go through your county Extension agent, but the herbarium does offer an online database where Florida residents can look at images of plants in the collection.DiseasesUF/IFAS Extension offers multiple plant diagnostic clinics and labs, which make up the Florida Plant Diagnostic Network. These diagnostic clinics use living-plant samples to make disease diagnoses.An important note: once a plant is dead, our Extension professionals are unable to make a disease diagnosis. Harmful fungi and bacteria are present in all Florida soils, and many secondary bacteria and fungi will start to grow on a dead plant. These two factors make it impossible to determine what, if any, disease killed a plant.Contact your county's Extension office for help and information on preparing a plant or turf sample to send to a diagnostic lab. The lab will charge $40 per sample sent. (Certain disease tests are no charge.)Send properly packaged samples with the accompanying submission form (149KB pdf).Sometimes what you believe may be a disease is only a nutrient deficiency. Your local Extension agent can advise you if it would be worth testing your soil before doing a disease analysis. (Find more information from the Extension Soil Testing Laboratory.)Collecting a SampleGeneral guidelines include:·         Take samples before applying pesticides.·         Make sure samples are living (green).·         Include a large amount of plant material that covers the range of the symptoms.·         Do not mix different samples in the same submission bag.Contact your Extension office and read the submission guide for more details.Other IdentificationsUF/IFAS Extension offices are your source for answers to your questions and solutions for your life.

    by Theresa Badurek, Urban Horticulture Extension Agent, UF/IFAS Pinellas County ExtensionDahoon Holly, Ilex cassineWe all know that there are many beautiful holiday plants to enjoy this time of year. This year I would like to focus on a group of plants that not only bring us pleasure, but also provide something for our wildlife- hollies. There are several native hollies that we can grow here that provide food and habitat for our wildlife while also providing decoration both outside and in. Holly fruits are a favorite winter food for many birds and mammals, providing seasonal nutrition for our feathered and furry friends. In addition to providing a food source, holly shrubs and trees also provide habitat for many birds. While the most important benefit of these plants is enjoying them outdoors in their natural state, they can also be used as cut greens in holiday decorations (the evergreen varieties). Keep in mind that hollies are dioecious plants: the male and female flowers are on separate plants and female plants produce berries. If you are looking for berries for holiday décor you will want to make sure you have some female plants. Also, many of the dwarf varieties do not produce berries. If you don’t already have hollies in your landscape you may consider planting them now for next year. Hollies prefer part shade but most will tolerate full sun, they prefer acidic soils, and they all require a well-drained soil. Here are a few suggested native hollies:American Holly, Ilex opaca. This is the holly most traditionally associated with the holiday season. It has spiny leaves and red or yellow fruit. Click here for more info.  Fruit of Ilex opaca Foliage of Ilex opacaDahoon Holly, Ilex cassine. This holly makes a great specimen or street tree. It even has another seasonally appropriate common name- Christmas Berry.

    Sword Fern - Native or Not?

    Florida’s Native and Non-Native Sword Fernsby: Lara Miller, Natural Resource AgentJennifer Jones, Brooker Creek Preserve InternFlorida is home to many native fern species, including the Boston fern (Nephrolepis exalta) and giant sword fern (Nephrolepis biserrata), which can be difficult to distinguish from non-native ferns that grow in the same environments, such as Tuberous sword fern (Nephrolepis cordifolia) and the Asian sword fern (Nephrolepis multiflora). Each of these are often still sold in the nursery and landscape trade, and often confused or misidentified as the native species of fern. The NativesThe native Boston fern (Figure 1) has erect fronds that can reach up to 3 feet long and 6 inches wide. The round sori (clusters of spore-bearing organs) are in two rows near the underside of the pinnae (leaflet). It is commonly found in humid forests and swamps of Florida, although is native to other regions such as South and Central America. It is grown outdoors as well as indoors for ornamental value; their high humidity tolerance makes them a good candidate for both indoor and outdoor use. Figure 1. Native Boston FernThe native giant sword fern (Figure 2) has fronds that extend several feet and can be found in moist to wet soil. The species name comes from tiny teeth that alternate with larger teeth along the edge of each lance-like pinna. Underneath each pinna, round sori occur evenly around the entire edge. The petioles (stalk) are sparse to moderate with reddish to light brown hair-like scales. Tubers are never present in this species.Figure 2. Native Giant Sword FernThe Non-NativesSince the non-native ferns can be invasive and disruptive to native plant communities, it is very beneficial to be able to recognize the differences between them. The Asian sword fern and Tuberous sword fern are sold under various names, often ones of native origin. Tuberous sword fern (Figure 3) sometimes produces tubers, and it is the only one of the four ferns mentioned that is capable of doing so. The presence of these tubers alone is a distinct way to identify the species. The presence of scales on the upper side of the rachis (stem) that is distinctively darker at the point of attachment is another way to distinguish the tuberous sword fern from the other three species. Native sword fern has scales on the upper side and are homogenously colored. Figure 3. Non-Native Tuberous Sword FernTuberous sword fern can be distinguished from Asian sword fern (Figure 4) by its glabrous central vein of the pinnae contrasted by the presence of short stiff hairs that occur on the central vein of the pinnae of Asian and giant sword fern. The most distinguishing characteristic for Asian sword fern is a dense covering of dark brown, pressed scales with pale margins on mature petioles. Petiole scales of tuberous sword fern are dense, spreading, and pale brown, while those of native sword fern are sparse to moderate, reddish-brown, of a single color or slightly darkened at the point of attachment and have expanded bases with small hairs.

    Okra cropIf you come to us from up north, this is the time of year you would normally enjoy vegetable gardening. That’s not usually the case here in Florida. Sure, there’s plenty of sunshine and usually lots of rain… but the heat, oh my, the heat. Most crops people really want to grow just won’t perform in our subtropical summer temps, and it can be downright brutal to weed your garden mid-July. But what if you are determined to garden in the summer anyway? Besides sunscreen and lots of water to hydrate yourself, what do you need to know? Fresh watermelonsSummer crops for Florida are limited. Things like watermelon, black-eyed peas, okra, and sweet potatoes are best this time of year. If you are more interested in getting ready for the more diverse fall vegetable gardening season, black-eyed peas are a great choice. They are legumes and the help fix nitrogen in their roots. If you grow these as a cover crop and turn the plants into the soil before they produce peas, you will help nourish your soil with more nitrogen for the fall. You can grow and harvest the peas if you like, but this will reduce the amount of nitrogen put back into the soil.  Okra flower Sweet potatoes are healthy (superfood anyone?) and they grow on rather beautiful vines. Growing this crop is a great way to keep down weeds in your garden while keeping it beautiful all summer long. I don’t have much to say about okra- can you tell I’m not a fan? But, if you like gumbo this is the crop for you! Finally, watermelon is a fun crop, and a summertime favorite that would be ready late August or early September if you got it planted right now. You’re going to need some space for this one, as watermelon vines can grow up to 12’-16’ long! Plan accordingly. All of the usual tips and techniques apply when gardening in the summer as well. Things like mulching to keep down weeds and scouting for pests regularly to avoid infestation are always great advice. Keep an eye on plants to make sure they are getting enough water. We usually get plenty of water from rain in the summer, but not always. Be sure to avoid letting your garden wilt in the extreme summer heat. Plants grown in containers will need more frequent watering to avoid this.

    Is your landscape storm-ready (Part 3)

    Part 3: Properly Training Your Trees for Wind ResistanceThis week's blog was written by guest blogger Jane Morse. Jane Morse is the Pinellas County Commercial Horticulture Extension Agent. This is part two of a three-part series. Trees are like children. When they are young they need lots of training to make sure they grow up strong, straight and healthy. Proper pruning is extremely important for good tree structure and the health of the tree. The most wind-resistant tree form is one that has a single leader or trunk with evenly spaced branches. There should be no narrow forks or branches leaving the trunk and if there are multiple trunks with sharp V angles these are very likely to split apart in a storm. Tree branches should retain 2/3 of their canopy. The palm on the top has been improperly pruned.The one on the bottomhas been pruned properly.Palms, on the other hand, should never have their fronds removed above a horizontal line, or less than a 90 degree angle off of the trunk. The so-called “hurricane cut” is the worst cut of all for palms. Palms treated in this manner are robbed of food and vigor, and will be more likely to sustain severe damage or death from a hurricane. See these links for more about pruning: http://edis.ifas.ufl.edu/mg087and http://edis.ifas.ufl.edu/ep443. For suggestions on choosing a tree care professional, check this website: http://tinyurl.com/7gbqt6r.Having trees that are beautiful, strong, healthy and wind-resistant just takes a little know how. Now that you know what to look for, go outside and inspect your trees. Make sure they have good structure and enough space for their root systems. If a tree needs help, contact a certified arborist who can advise you about pruning steps that can be done to create good structure, or for possible removal if the tree is hazardous. And if a tree does fall or have to be removed, plant a new one. But plant a more storm-resistant one and make sure it gets regular pruning while young.

    Planting Wind Resistant Trees in Your LandscapeDr. Ed Gilman, Professor of Environmental Horticulture, University of Florida, consulting with a resident on wind resistant tree selection.This week's blog was written by guest blogger Jane Morse.  Jane Morse is the Pinellas County Commercial Horticulture Extension Agent.  This is part two of a three-part series.After you have selected a tree for your yard and are getting ready to plant it, you need to picture it full grown.  Make sure mature trees will have lots of space, both in the air and in the soil, which gives them a better chance of surviving storms.  Plant smaller trees near homes, power lines and other structures. All trees need a certain amount of root space based on their mature size.  Trees smaller than 30 feet tall need a soil area of at least 10-by-10 feet and should be at least two feet from paved surfaces.  Medium trees with a height and spread less than 50 feet need at least 20 x 20 feet should be six feet from pavement.  Trees with a height and spread greater than 50 feet need at least a 30-by- 30 foot area and should be 10 feet from pavement.  More space is needed if there is a high water table and the roots have less than a depth of 3 feet for rooting.When planting for shade it is more important to shade the east and west walls of a house than the roof. Small trees planted fairly close to the house for wall shade will be less hazardous than large trees which can fall on the house.  For more information, see these links: Urban Design for a Wind Resistant Urban Forest and Choosing Suitable Trees for Urban and Suburban Sites.If you are a do-it-yourself landscaper, dig the hole wide and shallow so that the top 10% of the root ball is above ground level.  The outer inch or so of the root ball should be shaved off to remove all circling roots, and mulch should be applied 3 inches thick and in an area 2 feet in diameter for each inch of tree trunk diameter.  Mulch should come up to the edge of the root ball, but not cover it.  Roots will expand best when there are no soil differences, so it is best to stick with the natural soil and not amend the planting hole.  Establishment takes time and providing enough water is critical to tree survival.  For more detail see this link: Planting Trees and Shrubs.Next week Part 3: Properly Training Your Trees for Wind Resistance

    This week's blog was written by guest blogger Jane Morse.  Jane Morse is the Pinellas County Commercial Horticulture Extension Agent.  This is part one of a three-part series.Part 1: Wind Resistant Trees for Your LandscapeWhen it comes to trees and storms, there are victims and there are survivors.  The question to ask yourself before the next – inevitable – big Florida storm is: Will your tree survive or will it come crashing down on your roof? Trees have a lot to contend with during storms. High winds snap them and break off branches.  Rain loosens the soil, making it harder for the roots to hold them up.  And the longer it takes for storms to move through an area, the more water accumulates in the soil and the more battering the trees take. A tree’s survival comes down to whether it is resistant to wind, if it is properly planted and pruned, has enough space for its root system, and is in good health.  Trees with these properties can help to protect your home during a storm.  Or at least minimize damage.  Here are some things to consider when adding new trees to your landscape:That some trees are naturally more resistant to wind has been shown by surveying those still standing after hurricanes.  They include southern magnolia, yaupon holly, dahoon holly, podocarpus, crape myrtle, pondcypress and baldcypress.  Palms in this category include pindo, areca, Alexander and sabal.  You can find a more comprehensive list at: http://edis.ifas.ufl.edu/pdffiles/FR/FR17300.pdf.According to the University of Florida's "Trees and Hurricanes," some of the weaker trees are ash, maple, water oaks, pecan, tulip poplar, Bradford pear, southern red oak, Australian pine, floss-silk tree, weeping banyan, silk oak and jacaranda.

    Fall is a great time to enjoy wildflowers in Florida. One of the wildflowers blooming in the Florida Botanical Gardens right now is Bee Balm, Monarda punctata. This is an herbaceous perennial that typically grows to about 18” tall and spreads. Like other herbaceous members of the mint family (Labiatae), Bee Balm has leaves that are in an opposite arrangement on a square stem. You can feel the angular shape of the stem by rolling it between your thumb and forefinger. The pinkish-purple showy parts that are most noticeable are not the flowers, but bracts. If you look closely above you can see the flowers above the bracts; the flower tubes are pale with purple spots. Bee Balm is attractive to bees, butterflies, and birds, which makes it an excellent plant for attracting wildlife. The Bee Balm in the Gardens is just buzzing with life right now!  Click here for more information on this plant.

    Green Gills and Fairy Rings

    This week's blog was written by guest blogger Dusty Purcell.  Dusty is a Mycologist/Plant Pathologist who studied at the University of Florida.This is the ‘Green Gill Mushroom’, Chlorophyllum molybdites.  If you live in Pinellas County during the summer months, I am almost 100% certain that you have seen this mushroom. For several reasons, it is an excellent first mushroom to learn:1.  It has a cool name. Chlorophyllum molybdites.  Sound it out phonetically.  No one will dare correct your pronunciation. Trust me.2.  It is extremely conspicuous.  These large pale mushrooms, often in large groups, poke up through the grass on sunny lawns and golf courses.  You can spot them while driving down the road.3.  It is very common.  They pop up en mass around town every year during the warm and wet months.4.  It is highly distinctive.  As far as I know, this is the only gilled mushroom with green spores.  Mature mushrooms have green gills (hence the common name).5.  It is poisonous, being responsible for the majority of reported mushroom poisonings in Florida. Eating them can cause severe intestinal distress including cramps, vomiting, and diarrhea severe enough to require hospitalization. You’ll find green gills following rains during summer and fall.  They may be alone but are more often found in groups.  They often sprout from the ground arranged in a line, arc or circle.  These circular arrangements of mushrooms are called fairy rings, and they are not uncommon sights in large open grassy areas like those found in parks and golf courses.  ‘Why do they grow in a ring?’ you may ask.  Well, have you ever seen mold growing on a Petri dish or a slice of bread?  The mold colony grows out from its center as a round expanding colony.  The fungus that produces this mushroom grows through the soil of a lawn in the same way.  As it gets larger the old central part of the colony dies, leaving a ring of living fungal colony to produce mushrooms when the weather is right.  They won’t hurt your grass… in fact they help decay grass clippings and other organic material in the soil.  This frees up nutrients for your lawn to use.  If, however, you are concerned about little ones (e.g. children and dogs) who put things found on the ground in their mouths, you may want to remove them from your yard.  You can pick them, put them in a bag, and throw them away with the trash.  This won’t eliminate the fungus from your yard, more mushrooms will likely sprout from the fungus growing in the soil, but it will make the yard safe for grazing family members. On the left is an immature Green Gill mushroom.  The cap has not yet expanded to expose the gills. On the right is a slightly older specimen. The cap has begun to open, revealing the gills.  Notice the ring of tissue that was left behind on the stem where the margin of the cap had been attached.You can find a thorough technical description in a good field guide to mushrooms.  Here you will find a simple but workable description and some decent pictures.  A good specimen may be 6-10 inches tall with a cap about as big around when fully expanded.  A ring of tissue encircles the stalk somewhere in its upper third, and the cap has tan to brown patches or scales clinging to its upper surface.  The gills are densely arranged on the underside of the cap and are not attached to the stalk.  The gills are white at first, but turn gray-green as the spores are produced.  The cap, stalk and ring may be white in fresh young specimens but are usually pale tan and darken to a light brown as the mushroom ages.  The gills, too, may turn brown as the mushroom ages. The caps of these mushrooms have been folded back so you can get a good look at the color of the gills.  The one on the left is younger and still has white gills.  The specimen on the right is mature; the gills have turned green as they are now covered with mature spores.  Notice also how the stem has darkened with age.Young specimens, with their white gills, can easily be mistaken for mushrooms of the genera Lepiota and Macrolepiota.  Old mushrooms, with their brownish gills, may be confused with members of the genus Agaricus.  So, even this highly unique mushroom has look-alikes. However, mature fresh specimens, with their distinctive green gills, cannot be mistaken for any mushroom that I know of.  A spore print, as seen in the photo below, is also a reliable way to determine spore color and confidently identify this neat toadstool. This spore print was made from a fresh mushroom that still had white gills.  They are easy to make.  Just cut the stalk off of the mushroom and place the cap on a sheet of paper with the gills facing down.  It may take a while…  The heavy spore deposit here was made by placing a damp paper towel on top of the cap, setting an inverted bowl on top of it, and putting it in the refrigerator overnight.  The bowl and moist paper towel keep the mushroom cap from drying out.  Mushroom hunters make spore prints to determine the spore color for proper identification using field guides.References and further reading:Fairy Ring fact sheet from the University of FloridaCommon Florida Mushrooms by James Kimbrough
