Rapid Decline of Post Oaks in Texas

I first became aware of this Decline of Post Oaks when visiting a Texas A&M AgriLife Extension booth at an annual trade show several years ago. I had been aware of how the severe drought in 2011 was continuing to plague our trees even more than a decade later, but had not heard of the Post Oak Decline. The incidence of Rapid Decline began in earnest after the severe drought of 2016. Since then I have experienced first hand the devastation this has caused to so many stately old trees.  [...]

Do Not Allow Grass to Grow Up to the Trunk of a Tree

There are several reasons why you should keep the grass back from the trunks of your trees.        String-trimmer damage to tree trunks is not reversible. Period. The vascular system that is damaged does not repair itself or re-grow after it has been damaged. Trees may show varying amounts of stress from string-trimmer damage, and the wound is a perfect place for disease organisms to enter the tree.             If grass has grown into the mulch ring around your tree, DO NOT USE [...]

Pruning for Oak Wilt Prevention

Oak Wilt Pruning Those of you who have heard the adage “February through June DO NOT PRUNE” probably know that it is in reference to the spread of Oak Wilt. We avoid pruning Oak Wilt susceptible trees like Live Oak and Red Oak during the time that the Nitidulid Beetle is active. This beetle has been identified as a vector of the Oak Wilt Fungus. It feeds on the sweet, sticky fungus that forms under the bark of infected Red Oaks in the spring, and can transmit that fungus to [...]

Winter Watering of Established Landscapes in Central Texas

  Winter Watering in Central Texas If you think you have a hard time adjusting to Central Texas drought, seasonal flooding, or freak freezing temperatures, think of what our plants go through! At least we can drink water, go inside to the air conditioning or warm ourselves with central heat. While rain and temperature are things that we cannot control, we can control the amount of water that our plants receive. When we are in a drought year, it is very important that we use our water carefully while keeping [...]

Tree Care and Maintenance

Watering: -Water your tree religiously for at least one year using the following guidelines, and subsequent years during the hottest months or if we experience high heat or drought conditions. -At the time of planting the tree needs to be deeply watered. Two days after planting the tree needs to be deeply watered again. You can do this by turning on the hose and laying it inside the mulch reservoir, about six inches from the trunk, running it at a steady stream for about thirty minutes. If the reservoir does [...]

How to Check Soil Drainage

Before you decide which species of tree to plant, it is very important to know how well your soil drains internally. Dig a hole that is one foot square and one foot deep. Fill it with water and leave it overnight to drain. Fill the hole with water again the next morning, and measure the level drop per hour. Setting a ruler into the hole and checking the drop hourly is one method. A 1"-3" drop per hour is acceptable, while a 2" drop per hour is ideal. If less [...]

Galls

Plant galls are fascinating to me. They are all around us, yet we seldom notice them unless they appear in a favorite landscape tree. Plant galls are produced by a variety of organisms which include mites, wasps, midges, thrips, fruit flies, moths, psyllids, and aphids, as well as bacteria and fungi. Most plant galls are not harmful to the host plant, with the exception of some formed by bacteria and fungi. Many plant galls are produced by the host plant in response to the egg laying activity of the insects [...]

Watering Trees During Drought

    High temperatures and long-term drought can have a profound effect on tree roots. Unfortunately, many times we do not learn this until we see the telltale signs of stress. Once stressed, trees are more susceptible to insects and diseases. Depending on how much root loss has occurred, a stressed tree may or may not survive. This tree is showing signs of Flux, which is an indication of stress. Click HERE for more info. It is important to be PROACTIVE to prevent stress in our trees. With a little [...]

Porcupine Damage to Trees

      Porcupines are nocturnal, solitary animals that most people are unaware of unless they see the damage they can cause to trees. Porcupines feed on the young bark, leaves and terminal twigs of trees. Damage is usually found high up in the branches of trees but can be found anywhere in the branches and even on the trunk of trees.             Porcupines prefer the inner bark, or phloem, which is more nutritious than the cambium or xylem tissue.            [...]

My New Tree is Crispy!

Establishing trees in the summer comes with its own set of challenges. Trees CAN be established in the summer, but it is necessary to understand the importance of consistent watering. I have always preferred hand-watering to any form of irrigation, as it requires a “hands on” approach and leaves nothing to chance. The tree that you bring home has a root system, in a pot, that has been providing water and nutrients for the entire canopy of that tree while being grown in the nursery setting. When you plant the [...]
