My Crape Myrtles Aren’t Blooming!

Every year I get several inquiries about why someone’s Crape Myrtle is not blooming. There are several conditions that might affect a Crape Myrtle’s bloom period. Read the causes below to help figure out why yours don’t bloom. *Different varieties begin blooming at different times. Natchez (white) is usually one of the first to begin blooming. Some varieties may not begin blooming until late June. *Crape Myrtles require at least 8 hours of direct sun to bloom. If your Crape Myrtle receives too much shade, it will not bloom. *Insects [...]

Japanese Maples in Central Texas

Japanese Maples can be an attractive addition to almost any landscape. To assure trees that thrive, locate your Japanese maple where it will receive dappled sun under the canopy of trees, with no more than two to three hours of morning sun. New growth on varieties with red leaves will be more brilliant if they receive a little direct sun, either in the morning or the evening. Japanese Maples will tolerate low winter temperatures quite well, but suffer from moisture loss from the leaves when exposed to our drying summer [...]

Texas Mountain Laurel

What’s that fragrance, you say? Does it smell like Grape NeHi Soda? That wonderful grape scent is coming from our native Texas Mountain Laurel. They usually bloom in March, and the blooming period may last 3-4 weeks. The Texas Mountain Laurel is an evergreen native tree that is quite drought tolerant, once established. Establishment can take up to three years, as it does with many trees. The old adage “the first year they sleep, the second year they creep, and the third year they leap” is appropriate for this gorgeous [...]

Twig Girdlers

    I came out one morning and my driveway was covered in the tips of the branches from my enormous Cedar tree. (Actually, what we call a Cedar in Central Texas is really an Ashe Juniper.)           I picked up one of the fallen branch tips. It was about 3-4” long.  I examined the cut end of the twig. Yep. I could see the smoothly chewed groove that caused the twig to fall. It was Twig Girdler damage, all right!           [...]

Why Trees Change Color in Fall

What determines if a plant will have good fall color?   Fall color in tree leaves is determined by many factors. Any tree grown from a seed, such as an acorn, will have genetic variability in developing fall color. This is observed by watching our native “Spanish Oaks”, aka Texas Red Oak, as the leaves begin to turn in fall. Many will have beautiful red fall color, but we also observe some trees with leaves that simply turn brown and hang on the tree most of the winter…. (this is [...]

How to Choose a Crape Myrtle

It may seem kind of silly to write about “Choosing a Crape Myrtle”. Don’t you just decide what color you like and buy that one? Well, maybe. But there are other factors to consider as well. We now have a plethora of varieties to choose from, some with dark colored leaves, different colors of exfoliating bark, brilliant fall colors from red to orange, and a myriad of flower colors.  While all of these are important, remember to first identify the mature height of Crape Myrtle that would be appropriate for the [...]

Photinia Leaf Spot

My Photinia Leaf Has Spots? If you have Red Tip Photinia in your yard, you are most likely familiar with the red-purple photinia leaf spots that can appear on the leaves. This spotting is caused by a fungus, Entomosporium, and can cause damage to Photinia and Indian Hawthorn. Other plants in the rose family that may be infected include loquat, flowering quince, pyracantha and pear. We frequently see severe damage after periods of frequent rainfall, although overhead watering for lawns that hits the shrubs is also a factor. The disease starts [...]

Tree Borers

Tree Borers Many tree boring insects are attracted to weakened, damaged, dying or dead plants. They are referred to as “secondary invaders” because they attack a plant only after it has been weakened by stress or injury. Wood boring insects that attack living, healthy trees are known as “primary invaders”, and may eventually kill trees. It is important to differentiate the two when implementing borer control methods.     Borer infestations usually go unnoticed until the tree shows external signs of damage, such as browning leaves or dying branches. The [...]

Trees That Fail to Thrive

Failure to Thrive The vast majority of diagnostic questions I receive each year are related to trees with health issues. Many of these issues could be avoided by proper (and consistent) care of the tree from the day it is planted. Sometimes things do go wrong, and knowing what to do can be instrumental in reviving the health of a tree. Trees have the amazing ability to “compartmentalize” diseased and damaged tissue, and to produce healthy tissue around it. If a tree has been stressed by environmental issues such as [...]
