Answer : The trees in our landscape serve many functions from adding color and beauty, providing food and shelter for birds, to offering shade during our hot summers. People have emotional attachments to their trees, and of course, you want to save it. If the tree was generally healthy and thriving before the storm, it may recover, depending on the extent of the damage.
It will depend on how much of the crown foliage and branches is intact, how big the wounds are, how much bark is damaged, and maybe even how much you want to save the tree. The Texas Forest Service offers this guide to assessing the degree of tree damage.
For minor damage, you can prune the damaged limb s and wait to see if the tree recovers. Major damage usually cannot be repaired and the tree should be considered a loss. When to call for help : If there are power lines down, or major branches hanging overhead, stay away.
Also, if climbing or extensive chain saw work is involved, leave it to the professionals. This link will help you find a certified arborist. Question : I live on the very east edge of Denton County, and want to know what type of Bermuda seed you could recommend to overseed my existing Bermuda. It gets plenty of water, lots of sun, and organic fertilizer, yet the results are mediocre. I would like to avoid laying new turf. Any suggestions are welcome!
Overseeding Bermudagrass is not difficult. Timing and preparation are important steps to ensure a good rate of germination. Here are the important steps and timing for our area:. Apply a pre-emergence herbicide for crabgrass, goosegrass, and other summer annual weeds. Timing of this step is critical and must be done when the soil temperature is cool and the summer annual weed seeds have not yet germinated.
Apply a post-emergence herbicide on cool-season weeds that are already growing in your lawn. Be careful to avoid overspray onto landscape plants you care about. Request a soil analysis to help you understand what nutrients are needed for a healthy lawn.
Prepare the seedbed where you plan to overseed. First, dethatch the existing lawn with a vertical mower. Then aerate the soil, and, lastly top-dress with sandy loam. Vertical mowers and aeration devices can be rented for use. Following the recommendations from your soil analysis, apply a starter-type fertilizer with an NPK ratio of about Nitrogen-Phosphorus-Potassium. Irrigate to settle the soil. No earlier than April, or when the temperatures are consistently over 70 degrees F, overseed your lawn with a good quality Bermudagrass seed suitable for this area.
Lightly rake the top-dressed soil to create ridges. Thoroughly soak the soil, but not to the point of run-off. Water daily until the seeds germinate. Water less frequently, but thoroughly, after the seeds germinate. Sharpen your mower blades to avoid pulling up or damaging the seedlings. Apply a pre-emergence herbicide in September to suppress cool-season weeds, and again in late winter to suppress warm-season weeds.
Question : Our lawn had a lot of roadside aster weeds. We used an herbicide on it last month, and this past weekend pulled the dead weeds. A lot of dirt is now showing in the lawn. What cover is recommended to prevent weeds from settling there? Do we seed it with ryegrass or put turf down? I will include suggestions and links to help you decide which alternative would be best for you. If it were me, I would prefer to put down sod now in the affected areas.
If you choose this option, bear in mind that the new sod will not root well until next spring, so it will need to be watered carefully through the winter and early spring.
See link, below, for details. An inexpensive soil moisture meter will help gauge whether irrigation is needed. Remember, roots need oxygen as much as they need water, so make sure not to drown your sod, nor allow it to dry out for extended periods of time. When the grass exits dormancy in spring, the roots will begin to establish themselves in your soil. Infrequent, deep watering of established turf coaxes roots deeper into the soil and protects the lawn from drought stress and problems caused by overwatering and frequent watering.
Below is a great resource for watering North Texas clay soil:. It will require patience, but long term, your best bet is a year-round routine for fertilization and weed control, using both chemical and mechanical methods.
The following link offers detailed information:. We cut it down with chain saws but wonder how we can stop it from growing back. Is there a legal herbicide you could recommend to control it? There are two main types of bamboo, one growing slowly in a clumping habit and the other growing rapidly in a running habit. Safe to say that your bamboo is the running variety. The running rhizomes can spread up to five feet a year. You may need to employ simultaneously a number of control measures to beat back the bamboo, but it can be done.
Leaves gain energy from the sun via photosynthesis and store that energy in the rhizomes. This stored fuel drives propagation. It is a slow process, but continual mowing of new growth will help deplete the rhizomes of the energy required to spread. Be prepared to mow for two to three growing seasons.
A barrier of concrete, treated wood, plastic or metal should be installed at a depth of at least 18 inches to deflect rhizome intrusion. Make sure the barrier extends at least two inches above grade, as those pesky rhizomes can spread at soil surface, as well.
For herbicide control, use a non-selective product containing the active ingredient, glyphosate. Be warned: Just as with the mowing method, you should know that it may take two to three growing seasons to gain control with the herbicide.
Please research each option for yourself and decide which of the two would be best for your situation. In fact, read the product label completely before purchase so you can also buy any needed personal protective equipment PPE.
However tedious it might seem, use all PPE as instructed. Apply only when bamboo is actively growing and when rain is not anticipated in the 24 hours after treatment.
Do not treat on a windy day, otherwise, overspray of the chemical can damage nearby plants. Saturate the leaves, but avoid runoff. Once the chemical is dry, people and pets can enter the treated area. Question: Are there things I should do now, in August and September, to reduce the number of weeds and improve my lawn next year? I have a combination of St.
Augustine in shady areas and Bermuda in sunny areas of my lawn. Answer: You are a very smart gardener! Maintaining St. I have pulled them, overseeded, everything I can think of with the exception of killing the grass, and nothing gets rid of them. I am all organic and we do over-seed with ryegrass in the winter. I use Bermuda grass in the front yard and that section of the yard gets 8 hours of sun.
I feel like that section of grass is just unhealthy. Will anything make them go away and never come back? Answer: Grassbur, also known as field sandbur Cenchrus spinifex , is a summer annual grassy weed that grows in all types of soils and can be found in just about everywhere grass is growing: residential lawns, sports fields, parks and along roadsides.
Grassbur has sharp, spiny burs that are part of their flower clusters. These burs seem to stick to and in everything and can be painful. It has a very long growing season, germinating in late spring and continuing to grow until the first killing frost in fall. It is a particularly pesky weed because they produce a lot of seeds that can lay dormant for a year or more before germinating. Because of this, grassbur cannot be eradicated in one season.
As with any chemical applied in the landscape, either organic or inorganic, read the label carefully for the suitability, directions for use, and follow all safety precautions. The best defense for grassbur and other lawn weeds is a healthy lawn. It would be helpful to have a soil analysis done. The analysis will help you understand what nutrients your soil needs to grow healthy turf.
The turf gets 6 hours of sun daily. Would core aeration help? Turf needs oxygen as much as it needs water, so periodic core aeration advances the absorption of both elements. Topdressing with compost afterward further improves soil by adding microbes and nutrients to grow healthy roots, to discourage suffocating thatch, and to improve water infiltration. To determine if your lawn would benefit from aeration, do a screwdriver test.
This task should be done in the cool of the day during times of active turf growth, not during dormancy. March and October Soil needs to be somewhat moist for best results; waiting hours after irrigation or significant rain should be sufficient.

Very few Anaheim or New Mexico pod cultivars possess resistance to potyviruses Greenleaf, ; Villalon, Several cultivars of virus-resistant peppers have been released over the last 20 years Villalon, ; Villalon et al. The production of hot and sweet peppers in Texas has fluctuated from to ha over the last 30 years. Currently, close to ha of hot peppers are cultivated statewide U. One of the most persistent problems of pepper production in south Texas has been virus infection.
Bacterial Leaf Spot bacterium — Xanthomonas campestris pv. Small, yellowish green to brown spots develop on the leaves. Under favorable weather conditions, spots become numerous and sometimes coalesce into large spots. Infected leaves turn yellow and fall off. The disease is seed and soilborne. Infected seed serves as source of infection to emerging seedlings. Splashing rains spread the organism from diseased to healthy plants in the field.
Vegetables II pp Cite as. Cultivated peppers are all members of the new world genus Capsicum. Their production and consumption have steadily increased in the United States and worldwide during the 20 th century due to their roles as both vegetable and spice. Just like their solanaceous cousins, tomatoes and potatoes, peppers have rapidly become an important component of diverse cuisines around the world. This is reflected in the large acreages devoted to their production in such countries as India, Mexico, China, Korea, and the United States Table 1.

In Texas, the greatest challenge to vegetable producers is in the area of pest control. The mild climate prevalent in most of the state is extremely favorable for all forms of crop pest to flourish weeds, insects and diseases. Limited tools to combat these problems is one of the major contributing factors to the high risk associated with vegetable production in general. Successful production of organically grown vegetables requires an even higher level of management for profitability to occur because even fewer control tools are available to producers using this production system.
