    My Tree Has Tumors

    As oak trees are now fully leafing out and people start hanging out in the shade of the canopy, many of you are noticing strange growths on the branches. They look like potatoes, spiky cones and fuzz balls on the leaves and stems.  Don’t worry.  It’s just a harmless wasp that chose that tree to …

    Bark Stripping Squirrels

    Squirrel bark stripping damage on a Chinese elm.

    The squirrels are at it again! This time they are stripping the bark from the trunks of my Chinese elm (Ulmus parvifolia) trees. Squirrels feed on the bark of a number of other different tree species including oaks, maples, and pecans. There are a few theories as to why squirrels feed on tree bark. Pregnant Females …

    Benefit from Beneficial Insects

    A number of summers ago, I noticed whiteflies on a confederate rose plant in my landscape. I considered using an insecticide to control the whiteflies but decided against doing so after taking a closer look. What I found was a population of ladybugs – eggs, larvae, pupae and adults. Ladybug adults and larvae eat whiteflies, …

    Inspect and Wash to Prevent Azalea Lace Bug Damage

    Now is the time to prevent your azaleas from being attacked by lace bugs. The azalea lace bug, Stephanitis pyrioides, overwinters as eggs on the underside of infested leaves. Eggs hatch in late March and early April. The insect then passes through five nymphal instars before becoming an adult. It takes approximately one month for …

    Plan to Reduce Summer Weeds

    Remember last summer? The hot, dry days.  Grass drying up and turning brown.  Yet, the weeds are green and doing fine.  However, every herbicide label warns against applying when the temperatures are above 85 degrees and especially under drought conditions.  Those weeds flourished and dispersed seed everywhere.  Now, they are just sitting there ready to …

    What’s Eating My Tree?

    The Chinese elms in my yard are under attack.  They are dropping leaves and the temperature’s still in the 70s.  Upon closer look, they aren’t just dropping leaves but the tips of branches too.  What is going on?  Is there a new insect pest wreaking havoc on my trees?  Did I do something wrong?  No, …

    Spiny Spiders

    The year’s mild winter and frequent rain showers have created lush lawns and gardens with an abundance of insects. As a result, we are seeing many predator arthropods taking advantage of the available feast.  One of the morning interesting creatures in the garden is the spiny orb weaver spider (Gasteracantha cancriformis) that has an interesting …

    Sod Webworms May Soon Be in a Yard Near You!

    Tropical sod webworms (Herpetogramma phaeopteralis) have recently been encountered in a number of yards in the Panhandle. The worms usually feed in large groups and unfortunately, the first, and basically the only, sign of damage is often a large area of shorter grass due to their feeding. The arrival time of sod webworms is also …

    Is It a Salamander or Pocket Gopher?

    Pocket gopher is a furry animal known by many locals as “sandy mounder.” It was given this name because of the sandy mounds of excavated earth that the gopher pushes out of its underground burrows. The name sandy mounder, with time, became “salamander.” This animal is not a salamander at all. Salamanders are slimy amphibians …

    Distorted Plants

    Plants can become distorted for a wide variety of reasons. Sometimes nutrient deficiencies or toxicities can cause plants to become distorted. Sometimes excessive amounts of water or sunlight can cause plants to become distorted. And sometimes insect feeding damage can be the culprit. Insects can cause plant mutations by feeding alone or by vectoring disease …
