Florida‘s State Tree. Palm Mostly Right

Quick! What is the official Florida state tree? If you answered “palm tree.” you’re mostly right. After all, Florida is synonymous with warm, sunny days; sultry evenings and, of course, palm trees. But there are 2,600 varieties of palm trees and the one Florida calls its “official” tree is the Sabal Palmetto Palm. Also called a cabbage palm because the central bud can be eaten raw or cooked, it isn’t a good idea to do either since damaging the bud will kill the tree.

Newspaper Reports on Spiral Whitefly Invasion

Last week, the Palm Beach Post ran a story on the Rugose spiraling whitefly invasion (Whiteflies hit Palm Beach County homeowners’ trees, plants, pools, Aug. 16, 2012). If you’re a regular reader of this blog, then you knew about the Rugose spiraling whitefly more than two weeks earlier (The Spiral Whitefly Invasion – A New Pest in Town, Aug. 1). We don’t want to brag about our timeliness; the Post certainly has more resources than us. But, it does beg the question (with apologies to Ghostbusters):

The Spiral Whitefly Invasion - A New Pest in Town

As if it isn’t bad enough that our ficus hedges have been under attack by the fig or ficus whitefly (see Whiteflies Leave Wide Path of Defoliation, Feb. 14, 2012), now we have to contend with a new whitefly to our area, the rugose spiraling whitefly. This newest of more than 75 whitefly species found in Florida is of particular concern in Palm Beach County because of their voracious appetite for your trees and plants. Well established along the eastern portions of the county, they are now making their way west.

Do You Have These in Your Landscape?

• Bird of Paradise
• Coconut Palm
• Bismark Palm
• Pygmy Date Palm (Roebelenii’s)
• Gumbo Limbo
• Pandanum (Screw-Pine Palm), to name a few

If so, this new spiral whitefly will attack all these palms, plants and more. It is completely different than the ficus whitefly found on shrubs. But before you panic, the University of Florida IFAS Extension says that unlike its cousin the ficus whitefly, the rugose spiraling whitefly hasn’t caused severe plant damage, such as plant death or severe branch die-back.

Mighty Mite Is On Its Way to a Palm Near You

After devastating coconut palm trees in the Caribbean, the red palm mite made its way to Palm Beach County almost five years ago when it was discovered in Palm Beach Gardens. Today, these critters are known from 386 sites in five Florida counties, which includes 154 sites alone in Palm Beach County. The invasion of this species is the largest mite explosion ever observed in the Americas.

Sucks the Life Out

Bright red with a long, spatulate body, this “mighty mite” is known to feed and reproduce on at least 32 palm species, bananas, gingers and heliconias. This pest lives for about 26 days. It thrives on the underside of leaves and fronds and in high numbers causes yellowing of the leaves followed by death of plant tissue. They stick their sucking snouts into the stomata of leaves and feed directly from deep within the leaf. This causes mechanical damage to the stomata so that they are no longer able to close and the leaf dries out.

Chinch Bugs #1 Enemy of St. Augustine Grass

Every weekend you’re out there tending to your lawn, weeding, watering and spending hundreds, if not thousands, of dollars on food and fertilizer to make it the pride and the envy of the neighborhood only to one day discover the grass inexplicably turning yellow, then reddish-brown and finally dying. This is the foul work of the chinch bug. A complex of three different species within the same family, chinch bugs have piercing-sucking mouthparts and they feed on the sap of grass plants.

Weeds Are Plants Growing in the Wrong Place

Weeds are plants, too. They don’t get no respect, though, because they’re growing in the wrong place, such as your lawn, garden and even cracks in the pavement. If left untreated, weeds will spread to compete with the grass for space, food and light. In the end, they will ruin the look of your lawn.

Basically, weeds come in three varieties: grassy, sedge and broadleaf. Some weeds are perennials, which means they can last for more than one growing season, while annuals germinate, flower and die all within one season. Broadleaf weeds, which are characterized by wide, flat leaves, are most common in lawns and gardens. Dandelion, plantain and other broadleaf weeds are among the most common and troublesome turf pest problems in plants.
