North Florida vegetable gardeners have made it to summer and now the plants and gardeners are starting to give in to the heat and humidity. The squash has likely succumbed to squash vine borers, many of the tomato varieties are having trouble setting fruit, stink bugs are all over, and gardeners easily wilt by noon. This is a good time to use our oppressive heat to your advantage in the vegetable garden by solarizing the soil.

Soil solarization is a method of pest control that creates a greenhouse to heat up the soil in an effort to drive away pests. Pests that can be reduced with soil solarization include weeds, various soil-borne fungal pathogens, and nematodes. Weed seeds can actually be killed by the increased temperatures, sometimes as high as 140 degrees Fahrenheit, while fungi and nematodes are merely driven deeper into the soil layer as they try to escape the heat. Although they are not killed, this can help vegetable gardeners as it may take these organisms 3-4 months to repopulate in high enough numbers to cause damage. Soil solarization can be considered another tool in your integrated pest management (IPM) toolbox, along with other cultural, physical, and chemical means of pest control.

To properly execute soil solarization, the site should be in full sun and the existing vegetation removed, either by hand or with a tiller or other implement. Tilling can help loosen the soil surface and allow heat to penetrate deeper in the soil horizon. Before being covered with plastic, the area should receive rainfall or be irrigated, as the water will help conduct heat to greater depths. The next step is to cover the area with plastic. Note that this can also be done over raised beds! Clear plastic is best for maximum solar radiation penetration. Black plastic will heat up mostly on the surface and opaque plastic sheeting may not let enough light in to get temperatures high enough. The plastic should be slightly larger than the area covered, as the edges will need to be buried to create an air-tight seal. It’s recommended to leave the plastic in place for at least six to eight weeks, just in time to begin fall gardening preparations.
It’s important to monitor the site while it’s “cooking” to look for any holes that might appear. Small holes can be repaired with duct tape, while large holes or rips in the plastic may require starting over. Overlapping strips of plastic is not recommended since too much heat will be lost.
You may be wondering what happens to all of the good soil microbes. Well, unfortunately, they are also either killed or suppressed. Fortunately, researchers have found that they are able to repopulate quicker than the pest organisms, especially in soils with a good amount of organic matter.

A lot can go wrong in a garden or landscape, but proper preparation can help to avoid many of these problems from popping up in the first place. For some of these problems, a good preventative measure is mulch.
Pine straw is a common material used as mulch.
Mulch is any material that’s spread over the surface of the soil. One of the most common materials used in our area is pine straw, which is simply the needles of pine trees harvested from forested lands. Pine bark, another byproduct of the forestry industry, can be found easily as well. Both of these mulches will tend to have an acidifying effect on soils over time.
Other popular mulches include shredded or chipped wood. Melaleuca trees were originally planted in South Florida in an attempt to convert wetlands into farmable areas; to help remove this invasive species, the trees are now cut and ground into mulch. Eucalyptus mulch is also popular, as well as cypress, though it can be difficult to determine where cypress mulch originated from. Improperly harvested cypress can damage Florida’s natural wetlands. Hardwood mulch from other species may also be found.
Utility companies may sometimes give away mulch produced as they trim trees and bushes along their power lines, but this should be used only with the understanding that it may contain weed seeds or traces of herbicides or other chemicals. Homeowners may sometimes produce their own mulch in the form of raked leaves or grass clippings, but the same concerns about weed seeds and chemicals apply here as well.
Mulch can be used to help avoid hitting plants with a mower or trimmer.
Gravel or pebbles may often be used, especially in wet areas, or close to houses where flammable materials may be ill advised. Lastly, garden mulches may include materials such as paper or plastic spread in sheets over the ground.
Choosing the proper mulch can depend on the reason for its use. There are a number of effects mulch can have on a garden or landscaping bed. Mulch can help to retain moisture in the soil, keep weed growth down, reduce erosion, and act as a temperature buffer for the soil and plant roots below. It may also add visual appeal and help to keep lawn mowers and trimmers from needing to get too close to plants which may be damaged by them.
Whatever the reasons for adding mulch, there are a few things to avoid. Do not mound mulch around the base of plants. Moisture held against the trunk or stem of a plant can lead to fungal problems. Try to maintain a layer two to four inches deep. Any less and weeds will grow through the material; more mulch will not allow water to filter properly to the ground. Finally, if mulch becomes clumped and matted over time, do not let these block air or moisture to areas below. Rake or stir the mulch to evenly spread it.
You can find more information on mulching at our EDIS site https://edis.ifas.ufl.edu/topic_mulch or in the Florida Friendly Landscaping site at https://ffl.ifas.ufl.edu/handbook/Mulch_vSept09.pdf.

As temperatures lean more toward summertime highs, conditions can sometimes leave a landscape looking sad. Water issues can be a major source of headaches for homeowners when they cause plants to decline. The cause is not always readily apparent.

Water is something not even the meanest cactus in the driest desert can do without. Too little, and plants start to develop symptoms of drought stress. These symptoms include more than just wilting; stunted growth, curling or rolling leaves, fruit or leaves dropping, and yellowing or browning especially at leaf edges are all clues that a plant is thirsty. In lawns, underwatered grass may not spring back when stepped upon, leaving visible footprints in the turf. Long periods of drought stress can cause grass to thin. Plants exhibiting symptoms such as these may require extra water. A layer of mulch around landscaping can also help to retain moisture if soil dries out too quickly. Newly installed plants are particularly susceptible to drying out, and hot weather dries out all plants more quickly.
Plants can also be overwatered, however. Even with the well-drained, sandy soils that are present in much of the Florida Panhandle, it is possible to put too much water on a lawn or landscape. This can lead to problems that may be similar to those caused by underwatering – stunted growth, curled leaves, wilting, limbs or leaves dying, and increases in fungal disease can all occur. Lawns may become patchy and weeds, especially those that enjoy damp conditions such as sedges or dollarweed may establish themselves.

Stress of any sort can also leave plants more susceptible to pest and disease issues. A healthy plant is better able to compete with weeds and fight off infestation or infection. If you notice problems with fungal disease, increased insect populations, or weed issues, it could be made worse by over- or underwatering!
To help avoid watering issues, make sure plants with similar water requirements are planted near one another. If you have irrigation for your lawn or landscape, it is important to calibrate it regularly. Make sure the system has a rainfall shutoff device and check systems for damaged or malfunctioning emitters. And remember, if you are having trouble with your lawn or landscape, contact your local Extension office for help!

Introduction
Rhizomatous begonias are a large group of Begonia species, hybrids and selections characterized by large, sometimes-colorful leaves arising from thick rhizomes that grow along the soil surface. White or pink flower clusters that appear in late winter and spring are an extra bonus with these plants. Some types can be used in north Florida as herbaceous perennials that add bold leaf texture and color as well as flowers to shady gardens.
Begonia mass planting
Common rhizomatous begonias such as Begonia nelumbiifolia, ‘Erythrophylla’ (“Beefsteak”), and ‘Ricinifolia’ have long been grown outdoors in south and central Florida gardens as herbaceous perennials. North of these areas, rhizomatous begonias were considered cold sensitive and thus used strictly as pot-grown plants grown indoors or protected over winter. Nonetheless, north Florida trials testing the performance of outdoor, in-ground plantings started in Tallahassee and Gainesville as long ago as the late 1980s and early 1990s. With the proven success of some rhizomatous begonias in north Florida, interest in these plants increased rapidly in the early 2000s. Since then, savvy north Florida gardeners have been delighted by the possibility of using rhizomatous begonias as interesting herbaceous perennials for the shade garden. While temperatures below freezing can damage or kill leaves, these plants will usually produce new leaves from the rhizomes once warmer temperatures return in spring.
Plant Description Under North Florida Conditions
Leaves of rhizomatous begonias are this plant’s most distinctive feature and are why this group is so appealing to gardeners. Leaves often are large, from a few inches wide to almost 3 ft. in diameter (as reported for the cultivar ‘Freddie’ under the right conditions). Leaf shape may be rounded, star-shaped or irregularly edged, and leaf colors include burgundy, red, bronze, chartreuse, silver, and various shades of green including one so dark as to be almost black. Many types have leaves displaying patterns of one or more colors and some have silver or red markings. Undersides of leaves are often burgundy-colored, and leaf stems (petioles) also may exhibit colors other than or in addition to green. Leaves may be smooth, textured, or fuzzy-appearing due to large numbers of sometimes conspicuous hairs. Some types have leaves with an interesting three-dimensional spiral located on top of the leaf where the leaf blade attaches to the stem.
Begonia ‘Big Mac’ foliage
Rhizomatous begonia rhizomes are thickened, fleshy stems 1 to 2 in. or more in diameter that grow, branch and spread horizontally at or just below the soil surface, often in the mulch or leaf duff. Adventitious roots develop along the rhizome, and dormant buds embedded in the horizontal stem can be stimulated to grow new leaves after damage, stress or when divided. With age, as rhizomes grow outward, the oldest part of the rhizome will stop producing leaves and eventually die.
The rhizomes contain water and food reserves that allow this type of begonia to survive environmental stresses like drought as well as leaf loss or damage from cold temperatures. Shoots and roots can grow from the rhizome even if leaves and roots are killed or damaged.
Flowers occur in late winter to spring, depending on the species, cultivar and weather, and are quite showy on some selections. Flowers typically are white to various shades of pink and occur in a cluster (technically called a cyme) held above the foliage, in some cases dramatically high above the foliage. Individual flowers may range in size from 3/8-inch to over 2 inches at their widest point and a flower cluster may contain a few to over 120 individual flowers, depending on selection and growing conditions. A mature rhizomatous begonia may have an extended period of flowering, providing weeks of color. This long floral display results from large numbers of flowers developing sequentially on an individual flower cluster such that new flowers are still forming long after the first flowers have opened. Furthermore, multiple flower clusters appear over an extended time period. Flowers occasionally are pollinated and form winged seed capsules, though seed production and viability are variable. After flowering, the leaves remain a point of interest in the garden due to their size, lush appearance, interesting shapes and colorful patterns.
Cultural Requirements, Use and Maintenance
Rhizomatous begonias grow best in light shade or indirect light but can tolerate morning sun. Plants thrive in rich, organic, well-drained soil that is moist but not wet. A layer of organic mulch or leaf litter often is enough to provide basic conditions for growth in most soils if they are well-drained. Accordingly, organic mulches or leaf litter should be applied regularly around plants. Fertilizer stimulates growth but decomposing organic mulches can provide adequate nutrients, except perhaps with poor or sandy soils.
Newly planted begonias should be watered regularly. After establishment, most rhizomatous begonias benefit from regular watering but only require irrigation during periods of drought or extended dry weather.
An individual plant makes an attractive specimen plant in a container or in the garden. With time, a rhizomatous begonia can spread and, in the garden, develop into a patch. Alternatively, planting large numbers of the same rhizomatous begonia can create a very dramatic garden border, mass planting, or groundcover, especially in spring when all plants are flowering. To achieve this effect more rapidly and with smaller numbers of plants, tips of rhizomes can be pruned to stimulate rhizome branching and result in a denser plant or patch. Rhizome tip pruning should be done after plants finish flowering. Plants can be divided and moved easily since only the rhizome is needed to establish a new plant, but this should occur after flowering and early in the growing season so plants have long enough to establish before cold weather.
For aesthetic purposes, dead or damaged leaves may be removed as needed but especially after frosts and hard freezes. Similarly, leaves that overwinter often become “ratty” in appearance with time and may be removed without affecting plant growth.
Potential Problems
Rhizomatous begonias have few pests or other problems. Mealy bugs can occasionally infest plants. As with other large-leaved plants, wind or physical contact can tear and damage leaves. In north Florida, winter frosts and freezes can damage and disfigure leaves or kill leaves entirely, causing them to lose structural integrity and collapse, appearing mushy. Foliage may be protected during cold weather by frost cloth, sheets or other typical cold protection strategies, though heavy coverings could themselves damage leaves.
Rhizomes themselves usually survive cold weather because they are insulated from low temperatures by being half-buried in the ground and/or being covered by mulch. Adding mulch regularly to rhizomatous begonia plants will provide increased freeze-protection. Also, their typical planting location under tree canopies protects plants from a radiation freeze. Soil drainage is a more important factor for rhizomes since wet soil conditions could lead to rot, particularly in winter.
Common Types and their Descriptions Under North Florida Conditions
With hundreds of species and thousands of cultivars and hybrids, rhizomatous begonias can be overwhelming. Many rhizomatous begonias look alike and even experts have difficulty distinguishing species and cultivars. Many grown in north Florida have their origins in Mexico, Central and South America, though the Begonia Family is huge and species are found nearly world-wide.
Begonia heracleifolia
Technically rhizomatous begonias include Rex begonias, a group derived from Asian native, Begonia rex, and known for their especially colorful leaves. However, most Rex begonias do not grow well in Florida’s heat, high rainfall and high humidity, and so these begonias are excluded here.
Begonias listed below represent types that have proven resilient and usually cold hardy in north Florida USDA Cold Hardiness Zone 8b.
Species:
Begonia heracleifolia: The species boasts star-shaped leaves up to 6 in. across on stiff, hairy, thick leaf stems (petioles) up to 5 in. long. Each of the pointed leaf lobes is edged in dark green and has a chartreuse stripe along the central midrib, adding contrast. Spectacular sprays of pale pink flowers appear in late winter in clusters measuring 3 ½ in. by 4 ½ in. on 6-in. flower stalks (pedicels). Each cluster contains about 30 or more flowers, each about 1 in. across. As the season goes on, foliage gets showier and showier. It often dies down after winter freezes but re-emerges in late spring.
Begonia nelumbiifolia
- nelumbiifolia: This cold hardy begonia is known for its exceptionally large, water lotus-shaped leaves, creating a stunning specimen. Individual leaves can grow as large as 18 in. by 14 in. on leaf stems as long as 36 in. but 12 in. by 9 in. leaves are more typical. As temperatures warm, new developing foliage continues to get bigger, growing into very large leaves by fall. There also is a form in which the medium green leaves have red veining. White flowers are displayed above the foliage in mid to late spring in airy clusters measuring 7 ½ in. to more than 12 in. across on stems up to 48 in. tall. Clusters may contain as many as an astounding 120 flowers, each about ¾ in. across at its widest point.
2. popenoei: Huge rounded leaves with red veins and undersides make this a specimen plant which can grow to 3 ½ ft. tall and wide. Hardy with protection, it throws up tall stalks with clusters of white flowers in late winter.
Cultivars:
“Beefsteak”: This catch-all name refers to the original beefsteak begonia, ‘Erythrophylla’, as well as many derivatives that look similar. Beefsteak begonias characteristically have rounded leaves with a glossy green to bronze top surface and reddish undersides. Leaves range in size from 4 to 7 in. in diameter, and flower clusters are on stems up to 18 in. tall. ‘Erythrophylla’ was developed in 1847 and is considered a tough, vigorous plant, hence the common name, “beefsteak”. Given the long history and vigor, ‘Erythrophylla’ and derivative beefsteak begonias have long been shared as pass-along plants, world-wide as potted plants and later as an in-ground Florida garden plant. One type has ruddy, evergreen leaves and long-lasting, bold pink flower clusters. The scalloped 4-in leaves are on short 5 ½ in. reddish leaf stems but are most notable for remaining undamaged by temperatures down to the mid 20s °F, long after all other begonias’ leaves have turned to mush. Mid spring finds this plant topped by numerous clusters of dark pink flowers, with the display lasting 6 weeks or more. Individual clusters are about 8 in. by 5 in. on flower stems about 12 in. tall. Each cluster contains about 20 flowers each about ¾ in. wide at its widest point.
Begonia ‘Big Mac’ in flower
‘Big Mac’: This is a large, vigorous plant with enormous star-shaped leaves having reddish undertones and red leaf stems. The plant grows about 3 ft. tall and 2 ft. wide. Individual leaves may grow up to 18 in. wide on 16-in. leaf stems but typical leaves on younger plants are 10 in. to 12 in. wide. Individual white flowers are an amazing 2 in. wide at their widest point in clusters measuring 7 in. by 12 in. and containing about 75 flowers. Cold winters will knock it to the ground, but this begonia re-emerges again in late spring. This plant was hybridized in 1982 by Paul P. Lowe in Lake Park, Florida.
‘Joe Hayden’: This begonia features dramatic, dark, lobed leaves with burgundy undersides. Leaves are up to 8 in. long supported by leaf stems up to 9 in. long. In spring, the plant is topped by light pink flowers held high above the foliage. Each cluster measures about 5 in. by 7 in. on flower stems up to 26 in. tall. Each cluster contains more than 100 individual flowers, each about ¾ in. across at its widest point. This selection was hybridized in California in 1953 by Rudolf Ziesenhenne, but many similar selections have been made and are often confused with ‘Joe Hayden’.
Begonia ‘Joe Hayden’
Many other cultivars are common, but other cold hardy types suitable for north Florida include ‘Caribbean King’, ‘Caribbean Queen’, ‘Washington State’ and the catch-all ‘Ricinifolia’ types (with large, castor bean-shaped leaves). New breeding by scientists and enthusiasts promises to deliver many more types of rhizomatous begonias with increased foliage cold hardiness and an expanded range of foliage types and colors. A major Texas nursery introduced a series of rhizomatous begonia hybrids marketed as Crown Jewel Begonia™. The series currently features five patent-pending cultivars that are promoted as landscape plants for Zone 8. Additional breeding work is ongoing in north Florida.
Availability and Propagation
Rhizomatous begonias are available from Internet/mail order nurseries, some American Begonia Society members, other gardening groups, and plant societies. The introduction of trademarked rhizomatous begonias like Crown Jewel Begonia™ show promise for wider availability of rhizomatous begonias from nurseries.
Rhizomatous begonias are easily propagated by division, separation of rhizomes, or by rhizome pieces. When planting, place the rhizome or pieces (as small as 2 in. long) horizontally and half buried in a new in-ground location or in a container with potting soil. As with other begonia species, leaves may be used for propagation, though this method usually takes longer to achieve a size suitable for planting in the garden. Plants can be grown from seeds but production time is similarly long.

Fall oak tree leaves abound and can be recycled as landscape mulch. Photo credit: Larry Williams
Weed control is not top on my list as a reason to use mulch. There are weeds that can push through mulch such as nutsedge (nutgrass) or that can germinate and grow in the mulch. But done correctly, mulching plant beds and gardens can help inhibit some weeds. Tree leaves can be used as a mulch.
In addition to weed control, mulch provides other benefits. It can make landscapes look more attractive. It keeps roots evenly moist, acts to insulate roots from extreme heat and cold and can help decrease loss of soil from wind and water erosion. Mulch serves as a barrier to some soil-borne diseases, especially in the vegetable garden. And, as organic mulch breaks down, it improves the soil’s fertility, aeration, structure and drainage.
Tree leaves make good mulch. They can be placed on the soil surface beneath and around shrubs, trees, perennials, annuals and vegetables.
Fall leaves are abundant. Some people feel overwhelmed by the volume. One resident reported raking more than 100 large bags of leaves from his half-acre property. One large oak tree can contain over 250,000 leaves!
Tree leaves can be placed in landscape beds or around vegetables “as is” or chopped up with a shredder or mower into smaller pieces and then spread around vegetables, shrubs and trees. Mixing leaves from several different species of trees can make better leaf mulch. Leaves of the same size tend to mat together and produce a shingling effect that can shed water and reduce gas exchange in the soil. Shredded leaves stay seated better on the landscape than whole leaves.
A mulch layer three inches deep after settling is enough for most plants. If possible, extend the mulched areas out to the outermost leaves (called the drip line) and beyond. And be sure to pull the mulch back a few inches from the main trunk. Never pile mulch around the trunk.
Using those fallen tree leaves as mulch recycles a natural resource and saves you money, enriches your soil, fertilizes your plants and keeps them out of the local landfill.
So, instead of putting all those leaves curbside in plastic bags to be hauled off, use them to benefit your landscape, which may include less weeds.

Root rot may develop if citrus trees are mulched closer than 12″ to the trunk
Thankfully, cooler temperatures have finally made it to the Florida Panhandle, but it took until the middle of October. The last two months surely taught us lessons about helping our gardens beat the heat. One strategy to help plants cope with extreme heat or drought is mulching.
Many of us either have or can easily find, piles of wood chip mulch from fallen trees, thanks to the hurricane. This material will come in handy now, as fall and winter mulching is a great gardening practice with many benefits.
Think of mulch as a blanket for plants. By acting as a cover to the root system, mulch can perform as both a cooling factor during warm months and can help warm the root system during cooler weather, as well as assist in retaining moisture. This is important, as regulated soil moisture will accept rain or irrigation water much easier than crusty, dry soil. Water will simply runoff and can cause erosion in dry soil conditions. Mulch is a great weed barrier and is also aesthetically pleasing in the landscape by helping define borders and gives depth. A 3-4” thick layer of mulch, in a 2-3’ diameter, is typically a sufficient amount of mulch for landscape plants and fruit trees.
There are two types of mulch material that you’ll find in our area, organic or inert. Components of organic mulch include compost, bark, leaves grass clippings, straw, wood chips and even saw dust. Straw, wood chips and saw dust contain very little nitrogen, however. If mulching with these materials, it’s a good idea to add some nitrogen fertilizer. One or two cups of a complete fertilizer like 10-10-10 should help you avoid nutrient issues. Organic mulch will need to be replenished yearly to some degree, as it breaks down into a soil amending compost. This breakdown into compost will improve soil water holding capacity and fertility.
Inert mulch can be made of shells, gravel, pebbles, plastic and rubber. However, inert options are not as easy to use in controlling moisture and temperature levels and of course provides no nutrient value. With Inert mulch, you should always fertilize the area first, especially vegetable gardening. Use approximately two pounds of 10-10-10 fertilizer for every 100 square feet of vegetable garden. This may not seem like much fertilizer, but since plastic mulch reduces the amount of fertilizer that leaches out of the root zone of your plants, you can apply less fertilizer to begin with. That’s a big reason why UF/IFAS researchers recommend plastic mulch to commercial vegetable and ornamental producers in Florida, but organic mulches are more appropriate for most home garden settings.
Mulching may be one of the most valuable and cost-effective garden practices. Mulch helps control weeds, conserves moisture, moderates soil temperatures, improves soil fertility and last, but not least, adds to the beauty of the landscape.
