Citrus Troubleshooting: Common Problems

Nutrient deficiency: Iron deficiency is common in areas with calcareous soils and alkaline water. The iron may be present in the soil, but it is in a form that is unavailable to the plant when grown in alkaline conditions. Deficiency occurs on young leaves, and the veins remain green while the rest of the leaf is yellow. This condition can cause dieback of limbs and small fruit. Iron deficiency is also associated with excessively wet soils or prolonged wet conditions, as this depletes the root system and uptake of nutrients [...]

Choosing A Tree For Your Landscape

Choosing a Tree for your Landscape Having been involved in diagnosing tree disorders for many years, I feel the need to pass on some information that might help you avoid certain tree issues in your landscape. There are many factors to consider before choosing the right tree for your yard. Knowing these factors ahead of time can prevent loss of a tree. Choose a tree for the spot, not a spot for the tree! Know what mature height and spread the area you want to plant a tree in can [...]

Deer Injury to Trees

We are at the time of year again when the deer are in “the rut”. “The rut” refers to the breeding season, from about September to February in Central Texas. Anyone with newly planted or young trees in deer territory should be aware of this season and take measures to protect these trees from irreparable damage. Bucks will be rubbing their antlers on primarily young trees with thin bark, marking their “territory” and showing their dominance to intimidate other bucks. They begin this marking behavior in the fall, and then [...]

Roots and How They Grow

It is difficult to know how to water plants if we do not understand how (and where) their roots grow. Do we water just at the base of the plant? How long do we water a plant, and how deep does the water need to go? These are questions that I hear almost every day at the nursery. Let us begin with tree roots. In the first year, when establishing a newly planted tree, apply water to the area above the original root ball and about 1’ beyond. This will [...]

Crape Murder!

Is anyone thinking about murdering their Crape Myrtles this year? Is your yard crew "conditioned" to cut back your Crapes to NUBS???? Unfortunately, this practice began long ago, before we had choices in mature heights of our Crape Myrtles. They were planted too close to houses, and their height came too close to the eaves and gutters of the houses. Sooooo......the answer was to cut them back each year, thinking that this would not only control their height, but promote more blooms as well! This has been undeniably proven to be WRONG! [...]

Pecan Tips for Late August and Early September

Pecan kernels fill out their shells during August and September in Central Texas, usually between August 15 and September 15. This is a critical time for the trees to receive DEEP watering, covering an area at least out to the dripline of the tree. Without sufficient rains or irrigation, the kernel does not compress all the packing material tightly to the inside of the shell and some of that packing material adheres to the kernel. Unfortunately, the kernels themselves also suffer, as they will not be filled out as well, [...]

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 [...]

C – March Gardening Checklist

Annuals and Perennials Now is the time to be planting warm season annuals and perennials. Their root systems will have a chance to become established before the summer heat sets in, and you will not need to hand-water as long as you would if you wait to plant later.  Be ready to protect your newly planted/tender plants with frost cloth just in case we get a late freeze. The average last frost in Burnet County is March 15. Some of my favorite plants to add instant color to the winter-worn [...]

A – JANUARY GARDENING CHECKLIST

ANNUALS AND PERENNIALS: Continue watering and fertilizing cool-season annuals to ensure productive flowering.  Use NutriStar Color Star time-release fertilizer once a month for continuous feeding. Pansies are particularly heavy-feeders, and will always respond to fertilization with added blooms. Continue planting pansies, violas, ornamental cabbage and kale, snapdragons, dusty miller and cyclamen (protect cyclamen from freezes). VEGETABLES: If you plan on growing transplants for spring planting, count back 6-8 weeks from the last average frost date to start tomato and pepper seedlings. This is early to mid-January in Central Texas.  Place [...]

Trees for 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” 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…. What if I want to be SURE that a tree that I plant will have fall color? [...]
