    Lessons Learned from Farmers: Fire Ant Control

    As I near the three-year mark of being an Extension Agent, I think about how fortunate I am to have a career that not only encourages me to meet all our local farmers, but also to learn from them and share their knowledge with the community. A few months ago, I visited Blake Canter of …

    Mysterious Growths on Bald Cypress

    Bald cypress Taxodium distichum is a native tree that is commonly planted in landscapes because it is adaptable to many sites and grows quickly. It is an interesting tree because it has soft flat leaves that fall off in the winter like other deciduous shade trees; however, it belongs to the Cypress family which consists …

    Grass Worms

    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”.

    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, …

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, …
