Texas A&M AgriLife Extension offers extensive resources and guidance on tree care during droughts, recognizing the important role trees play in both urban and rural environments. Droughts can place a great deal of stress on trees, making them more susceptible to disease, pests and long-term damage. AgriLife Extension’s approach to tree care during droughts is designed to help homeowners, landowners and communities maintain the health of their trees through proper care and informed practices.
One of the fundamental aspects of AgriLife Extension’s tree care recommendations is the selection of drought-tolerant species. For new plantings, it is recommended to choose native or well-adapted trees that require less water and are better suited to withstand the often harsh, dry conditions in Texas. These species include varieties such as Virginia oak, Texas red oak and elm, which are known for their resilience in water-scarce environments.
Texas A&M AgriLife Extension emphasizes that efficient and effective irrigation techniques are critical to tree survival during drought periods. They recommend deep, infrequent watering to encourage deep root growth, which allows trees to access moisture in the soil for longer periods of time. This method is in contrast to shallow, frequent watering, which can result in weak, superficial roots that are more susceptible to drought stress.
AgriLife Extension recommends applying water slowly and directly to the root zone, which is usually below the tree canopy and extends to just above the drip line. It is also recommended to water early in the morning or late in the evening to minimize evaporation and ensure more water reaches the roots.
Mulching is another important strategy promoted by AgriLife Extension to conserve soil moisture and protect tree roots during drought periods. A 2- to 4-inch layer of organic mulch, such as wood chips or bark, spread around the trunk of the tree (but not touching the trunk) can significantly reduce soil water loss, regulate soil temperature, and suppress weed growth. Mulching also helps improve soil structure over time as it breaks down and improves the soil’s ability to retain moisture. During drought periods, it’s important to closely monitor trees for signs of stress. AgriLife Extension provides guidance on what to look for, including symptoms such as leaf wilting, browning, or premature leaf drop. They also advise watching for signs of pests or diseases that trees are more susceptible to when under drought stress. Early detection and treatment are critical to prevent further damage and ensure tree survival.
AgriLife Extension recommends minimal pruning during drought periods, as pruning can place greater stress on trees by removing foliage that is essential for photosynthesis and energy production. However, removing dead or diseased branches can help reduce the risk of pest infestations and other problems. To avoid further weakening the tree, proper pruning techniques such as those taught by AgriLife Extension are essential. AgriLife Extension offers a wealth of educational materials, including workshops, fact sheets and online resources, to help the public care for their trees during drought periods. These resources cover a wide range of topics, from basic tree care to advanced management practices for large properties and urban landscapes. Extension also offers in-person support through local offices, where experts can provide specific advice based on regional conditions.
In summary, Texas A&M AgriLife Extension’s tree care strategies during droughts focus on selecting the right species, implementing efficient irrigation and mulching practices, and closely monitoring tree health. By following these research-based guidelines, Texans can help their trees survive and thrive even in the challenging conditions of a drought. Through education, outreach, and practical advice, AgriLife Extension continues to support the preservation of Texas’ vital tree resources.
