Rose Rosette

Rose Rosette Disease Rose Rosette Disease (RRD) is a terrible rose disease that we’ve been hearing about for years, especially from the Dallas area. Unfortunately, we are starting to see more cases in Williamson County.  Rose Rosette has been around since the early 1940’s, but the problem seems to be growing in recent years as cultivated roses are used in more and more landscapes.  In 2011, Rose Rosette was diagnosed as a virus and researchers have recently confirmed it is spread by the eriophid mite Phyllocoptes fructiphilus.

Tomato Fruitworm

Tomato season is here! I harvested my first tomatoes last week from the Super Sweet 100 variety.  I would like to say that I was generous with my harvest, but those first few tomatoes did not make it out of the garden.  There’s nothing better than snacking on vine-ripened tomatoes as you work in the garden!

Summer Weed Control

  Weeds can be an ongoing battle, especially in a year like this with lots of rain.  I wrote about pre-emergent weed control a few months ago to help get a head start on weeds.  Unfortunately, sometimes we miss the window on timing of our application, or miss spots in the yard, or we just have some stubborn weeds.  If you have weeds popping up in your grass, don’t lose heart!  This is a good time to start to treat your weeds, when they are young and tender.

Crape Myrtle Bark Scale

Spring has officially sprung, and the wildflowers are outstanding this year! I have really enjoyed watching the wildflowers change from Bluebonnets to Primrose to Indian Blanket, and I cannot wait to see what comes next. Springtime also brings a lot of insects. One insect that I have written about before, Crape Myrtle Bark Scale (CMBS), is showing up this spring on Crape Myrtles and some new plant hosts.  CMBS is a small, white, sap-feeding insect that lives on the bark of crape myrtle trees.  The adult females look… Read More →

Irrigation Audit

As the weather warms up this spring, it’s time to start thinking about lawn care again. Right now is a great time to check your lawn irrigation system to make sure everything is ready to go for the summer watering season. An irrigation audit is a great way to make sure your system is operating efficiently so you can conserve water in your landscape. An irrigation audit consists of three parts: site inspection, performance testing, and irrigation scheduling. A site inspection is an easy step. Turn on your… Read More →

Large Patch in Turfgrass

Spring is in the air! I love seeing the trees bud out and the lawns green up, and I’m enjoying the nice weather.  Unfortunately, this beautiful spring weather has created perfect conditions for large patch in our St. Augustine grass and zoysia grass. Rhizoctonia solani is a fungus that is present in the soil year-round, but it takes advantage of cool temperatures and wet soil to cause a turfgrass disease known as large patch (sometimes referred to as brown patch in cool-season grasses.  The first symptom of large… Read More →

Aphids

Aphids are a hot topic of conversation at the AgriLife Extension Office this week! First, we spotted aphids in the vegetable garden!  Then several homeowners called with questions about their crape myrtles with black limbs, which is usually caused by sooty mold that colonizes on aphid “honeydew.”  Aphids are on the move and they are an interesting pest! Aphids are small, soft-bodied insects that range from 1/16 to 1/8 inch. They vary in color from black, gray, red, orange, green, yellow, blue-green, or white, depending on the species… Read More →

Tomato Varieties

It only seems right that March should usher in springtime weather, but this year it brought a strong cold front through Central Texas. Of course, the cold front came just in time to endanger the young tomato transplants that we passed out at a recent Tomato Lunch and Learn at the AgriLife Extension Office. Despite the cold, I am very excited to see how the tomatoes perform. This year we are trying out two new varieties at the Demonstration Garden, Celebration and Super Sweet 100.  Two very dedicated… Read More →

Crape Murder

It is almost spring in Texas, and the gardeners are getting busy! A few weeks ago, I shared information about pruning to help train plants, remove dead or diseased branches, and improve the quality of flowers and foliage.  As I drive around Williamson County, I have noticed that the crape myrtles in some landscapes are pruned a little too much.  In fact, we call this kind of pruning Crape Murder! Crape myrtles are a beautiful flowering plant that can be grown as a shrub or shaped into a… Read More →

Summer Weed Pre-emergent

It’s officially winter in Texas! Warm one day and cold the next!  This time of year is challenging for gardeners because we worry about protecting plants from freezes, getting enough chill hours for our fruit trees, and trying to control winter weeds like henbit, dandelion, and wild carrot.  Unfortunately, it’s also time to think about preventing our warm season weeds like crabgrass, carpetweed, pigweed, and many others. Mid-February is the time to put out pre-emergent weed killers if you have problems with weeds in your lawn. A pre-emergent… Read More →
