After you have chosen the right fertilizer, fungicide, herbicide or insecticide to apply to your landscape, the question becomes: how much do I buy? Labels on these products will tell you how many square feet it will cover – so that leads to the next question: how many square feet of lawn do I have?
Here’s an easy way to determine your square footage. This online tool from Sod Solutions uses GIS mapping to figure it out from the comfort of your lounge chair.

Interpreting Pesticide Label Wording
by Matthew Orwat | Aug 24, 2017
On Saturday, September 16th, 2017, from 9AM to 12PM, UF / IFAS Extension Washington County will be providing a rose gardening workshop for gardeners across the Panhandle. Many roses are hard to grow in the Florida Panhandle without investing considerable time and energy into spraying for insect and disease problems. This workshop will teach attendees how to select and sustainably grow roses adapted to the hot-humid conditions of the Southern Gulf Coast. There will be opportunities for outdoor learning and hands-on activities.
Topics include:
- Selection of disease resistant rose cultivars adapted to the lower South
- Resources to obtain hard to find easy care rose cultivars
- Soil and Nutrient Management
- Disease and insect management
- Irrigation
- Rose Propagation
Participants will be given the opportunity to propagate their own rose and take home their own propagation assembly to grow their own roses from scratch.
Refreshments will be provided and a door prize will be available.
Address: Washington County Ag Center Auditorium, 1424 Jackson Ave, Chipley FL 32428.
Pre Registration required for count: Contact Nikki or Cynthia at 850-638-6180 or email Matthew Orwat at mjorwat@ufl.edu

A New Yorker cartoon shows a lady shopping a garden center bench for plants. She has three choices at three price points: annuals, $6; perennials, $10; eternals, $749.95.
No matter what the cost, plants don’t live forever. And if they did, what would they cost? They’d probably cost more than $749.95. Even though we know plants don’t live forever, we still don’t want a plant that we purchased, planted and cared for to die an early death.
All too often, I find myself in the position of reminding a person of this fact of life – plants don’t live forever.

There are extremes, though. The bristlecone pine can live thousands of years. There is one that was named Methuselah, which, at one time, was believed to be the oldest living tree on record approaching more than 4,800 years of age in central California. But in the 1970’s, offspring of Methuselah all died because they were sent to low-altitude locations. The parent tree’s location in the White Mountains is two miles above sea level.
Even though the bristlecone pine can live thousands of years, misplacing it (planted at too low an altitude) results in the tree living a fraction of its potential life. The point is to plant the right plant in the right place. Make sure the plant is well suited for Florida and to the site conditions: that wet site, that dry site, that salty site, that high pH site, that shady site, that sunny site, etc.
The second point is to have realistic expectations based on the plant species. Some plants genetically will live longer than others. One of our longest-lived tree species in Florida is the live oak. There are live oak trees in Florida that are hundreds of years old. But don’t expect a silver maple to make it that long. It’s a shorter-lived tree species. In Florida, a thirty-year-old silver maple is probably in a state of decline due to old age.
The third point is to learn how to correctly plant and maintain the plants you have. For example, most woody plants (trees and shrubs), will live a much shorter life simply from being planted too deep. And an over fertilized centipedegrass lawn will go into a state of decline resulting in the lawn living a shorter life.
Plant the right plant in the right place, learn what it likes and provide it. And when the plant reaches the end of its life, replace it.
Many homeowners spend more than $749.95 attempting to turn a short-lived plant into an eternal plant.

Cupheas are perennials that produce bright orange, red, yellow or purple flowers all summer and fall. Some species are called cigar plants due to their tubular, cigar shaped flowers tipped in red or yellow (like a lit cigar). Others are sometimes called firecracker plants because their cylindrical flowers are bright red or orange (looking like a firecracker). By any name, their nectar-filled, tubular flowers are widely known for attracting large numbers of hummingbirds, butterflies and bees. In addition, young stems of some species are reddish, further adding color and contrast to the usually narrow, lance-shaped green foliage.
As a group, cupheas grow best in full to part sun (the brighter, the better) and well-drained, moderately fertile soil. Cupheas are drought tolerant once established, but grow faster and larger with regular moisture and occasional fertilization. Their origins in warm climates allow them to thrive in heat, but likewise make some species sensitive to cold winters. Those that are frost tender along the Gulf Coast are best placed in a sheltered location in the garden. Cupheas are pest and disease resistant and are not invasive in Florida. They are not truly deer resistant, yet reports suggest cupheas are not favored by deer.
Cupheas are great summer performers in bright, hot and dry locations. Flowering begins in summer and continues through fall until short days and cool weather reduce flowering or frosts cause dieback. Along the Gulf Coast, cool winter weather slows them down, so re-growth doesn’t occur until mid to late spring, and flowering usually doesn’t begin until days and nights are warm. Growth and appearance of many cupheas are improved if plants are pruned or cut to the ground in late winter.
Over 200 species of Cuphea are native to Mexico and the warm-temperate and tropical Americas. Of these and their hybrids, the cupheas listed below are great summer-flowering perennials for the northern Gulf Coast.
Cuphea micropetala
Photo courtesty: Gary Knox
Cigar Plant (Cuphea ignea)
This fine-textured plant produces red to orange tubular flowers about an inch long. This cigar plant is hardy to about 20°F. It grows about 2 feet tall and 3 feet wide along the Gulf Coast, though it would be a larger, evergreen shrub in warmer climates. This cuphea tends to have lanky growth, so occasional summer pruning will stimulate branching which results in more dense growth.
Cigar Plant or Candy Corn Plant (Cuphea micropetala)
Flowers are 1.5 inches long, emerge pale yellow and gradually turn orange from the base upwards, offering a colorful, two-tone effect. Foliage is hardy to 25-30°F and this cigar plant is root hardy to at least 15°F. Stems should be cut back to ground level in late winter to keep the plant tidy. Clumps spread slowly outward by rhizomes, and the plant will reach 3 feet tall and wide along the Gulf Coast.

Orange Cigar Plant or Schumann’s Cuphea (Cuphea schumannii)
This sprawling, floriferous cigar plant prefers moist, well-drained soil to thrive. Barrel-shaped, 1- to 1½-inch blooms are orange and yellow and sometimes have small purple petals at the tips. Flowers cover the branch terminals in the heat of summer and into fall. This plant is hardy in Zones 8 to 9 (at least down to the mid 20s°F). Unlike many other cupheas, leaves of orange cigar plant are oval- to heart-shaped. Stems grow 2 to 3 feet tall and readily flop or fall over. Plan to give orange cigar plant lots of room to sprawl through the garden!
Cuphea ‘David Verity’

‘David Verity’ Large Firecracker Plant (Cuphea ignea × micropetala ‘David Verity’)
This floriferous hybrid produces flowers that are dark orange with a short yellow-orange flared tip and purple filamentts. Well-adapted to the Gulf Coast, this plant is foliage hardy down to 25-30°F and root hardy to at least 15°F. In Zone 9 this plant will grow as an evergreen shrub up to 4 to 5 feet tall and wide, but it will be smaller in areas where frost or freezes occur. This selection is believed to be a hybrid between Cuphea ignea and C. micropetala that was given in the mid 1970s to David Verity, then the manager of the UCLA Mildred Mathias Botanic Garden. It was subsequently named for him when later brought into commercial production.
‘Vermillionaire®’ Large Firecracker Plant (Cuphea ‘Vermillionaire®’)
This new hybrid appears to be a superior cuphea because it grows as a naturally compact plant that produces more flowers than other selections. ‘Vermillionaire®’ grows about 24 inches or more tall and wide with a compact, mounding habit. Orange tubular flowers are produced continuously until late fall. This cuphea is too new to know the full extent of its hardiness, but it is expected to be a perennial in Zones 8 and higher.
Mexican Heather (Cuphea hyssopifolia)
Unlike the previous cupheas, this plant has small purple flowers, and some selections sport white flowers. Another difference is Mexican heather’s finely textured, bright green leaves. Gulf Coast Zone 8 plants are usually killed to the ground in winter, often recovering by summer but resulting in a compact plant growing less than 24 inches tall and wide. In Zones 9 and higher, Mexican heather is a larger-growing semi-evergreen tropical shrub. Reported pests are leaf-chewing beetles (Altica and Colaspis spp.) and the twig-dwelling lesser snow scale (Pinnaspis strachani). Mexican heather works well for edging beds or sidewalks, helping to define and soften pathways. Cultivars include Allyson, Lavender Lace, Purple Nurple™ and the white-flowered Monga (Itsy Bitsy° White) and ‘White Whispers’.
Bat-Faced Cuphea

Bat Face Cuphea (Cuphea llavea)
Each 1-inch flower consists of a purple tube lipped with two red, upright lobes. By viewing the flower with its tip facing you, it takes only a little imagination to see the two red lobes resemble large “ears” above the purple “face” of a bat, hence the name. Along the Gulf Coast, bat face cuphea grows mound-shaped 8 to 24 inches tall and wide, depending upon the selection. It is very heat and drought tolerant but requires better drainage than the other cupheas. Bat face cuphea is evergreen down to the upper 20s°F and root hardy into the lower 20s°F. Improved forms of bat face cuphea include the cultivars, Flamenco Samba, Georgia Scarlet, Mellow Yellow, Miss Priss, Tiny Mice®, Sriracha™ Pink, Sriracha™ Violet, Torpedo, Vienco° Lavender and Vienco° Red.

If you are one of the many that have taken advantage of the frequent rain in order to establish a new lawn, keep an eye open for “grass worms”. Though truly caterpillars, not worms, these destructive, chewing insects can wreak havoc on new sod.
Sod Webworm Photo by: Lyle Buss UF
Tropical sod webworm larvae are destructive pests of warm season turfgrasses in the southeastern U.S. especially on newly established sod. Larval feeding damage reduces turfgrass aesthetics, vigor, photosynthesis and density, which is very evident on finer-bladed grasses such as bermudagrass and zoysiagrass. Adults, a dull brown colored moth about ¾ inch long, rest in sheltered and shrubby areas during the day and are active at dusk. Females deposit clusters of 10-35 eggs on the upper surface of grass blades. The eggs hatch in 3-4 days and develop from a 1 mm long caterpillar to one over 11 mm long through six instars within 21 to 47 days, depending on temperature. Larval feeding occurs at night, leaving the grass looking ragged, shortened and missing.
Control should be against damaging larvae, not the flying moths. However, insecticidal soap applications to moth harboring areas can reduce re-population frequency if such areas are located. Soil-drenching soap flushes can be used to find the caterpillars, especially in dry and hot grass areas. Bacterial-based insecticides will control sod webworm caterpillars without impacting beneficial species as long as they are applied with each flush of grass growth.
Excessive fertilizing will lead to caterpillar outbreaks in lawns. Newly installed sod is usually rich in nutrients and rapid growing, which makes it very attractive to sod webworms. Grass installation over the summer months should be immediately followed by sod webworm treatment.
Fall Armyworm Photo by: Lyle Buss UF
Fall armyworms are also attracted to newly installed sod. They feed any time of the day or night, but are most active early in the morning or late in the evening. The 1 ½ inch long gray and white moth lays about 1,000 eggs in multiple masses on any vegetation. Two to 10 days later, the small caterpillar hatches and begins to grow to nearly 2 inches long over a two week period. The fall armyworm is easily recognized by its dark head marked with a distinct pale-colored inverted Y and the long black stripe running along each side of its body. These aggressive feeders “march” rapidly across grassed areas consuming every above-ground plant part. While bacterial-based insecticides will reduce the numbers, control of armyworms usually requires synthetic insecticides. Diligent inspection and early pesticide application is critical to establishment of new sod installed during the summer months.
