Trees

Trees provide numerous environmental, economic, and social benefits. We provide overview of the state’s tree resource and education on how to care for trees from large-acred forests to individual trees.

  • Texas is rapidly growing. Increasing the strain on ecosystems surrounding our communities. While we need homes, roads, commercial buildings, and other infrastructure, the materials and methods used increases stormwater runoff, heat island effects, loss of habitat for various species, and decreases green space.   That’s why we help communities develop sustainable, evidence-based strategies to conserve canopy […]
  • Texas leaf peeping A trip to the pine and hardwood forests of East Texas during October and November may display beautiful fall foliage. Or if you want to explore Central and West Texas, consider visiting the Lost Maples State Natural Area, a genetically distinct population of Bigtooth Maples (Acer grandidentatum) which was geographically isolated during […]
  • Mistletoe is a popular Yuletide decoration. However, it is a parasitic plant that can be damaging to trees. It also has poisonous properties and should never be eaten.   American mistletoe, genus Phoradendron, is a persistent, evergreen, photosynthetic (contains chlorophyll), seed-producing plant. It is parasitic on certain woody plants, primarily hardwood or broadleaf trees.  Except for […]
  • Lichen are unique organisms made up of a combination of fungi and algae that are symbiotic,  supporting each other.   The algae makes food through photosynthesis, which helps the fungi. In return, the fungi provide structure and retain moisture for the algae. Together, they form a self-sufficient partnership.  Lichen can grow on non-living things like rocks, […]
  • Burls are usually a rounded lump or protrusion located on the stem, branch, and, on rare occasion, the roots of trees. They are dense. These outgrowths can range in size from small to large and can have a rather unique look to each one.   While they may look cancerous to the tree, burls are benign […]
  • Witches’ broom is a plant disease characterized by the abnormal growth of dense clusters of shoots or branches, resembling a broom. The condition can affect a variety of trees and shrubs, leading to significant damage and reduced plant health.   Causes Witches’ broom can be caused by several factors, including:  Symptoms The primary symptom of witches’ […]
  • Vines grow on trees throughout our state. Many are harmless to trees, and some are quite attractive clinging to the trunk, like Virginia creeper (Parthenocissus quinquefolia) in the fall, with its bright red foliage.   Some vines, however, can harm the tree and possible kill it. Vines that grow through the tree and cover the canopy […]
  • Ball moss (Tillandsia recurvata) is a plant commonly found clinging to limbs of live oaks and other trees in the Southern U.S. It is in the Bromeliad family and related to Spanish moss (Tillandsia usneoides) and pineapple (Ananas comosus).   It can also be found growing on telephone wires and fences. Ball moss can grow on […]
  • It’s important to protect your young trees from damage caused by animals, which can severely hinder their growth and development. This starts with knowing what animals are present in your area and being able to determine what  damage they cause. Once you have an idea what you are dealing with, you can make a plan […]
  • When should you water? Check with your city or local water company for possible restrictions on watering methods and frequency during drought. You can water your trees at any time but if you can, avoid watering during the hottest part of the day — 10 a.m. to 6 p.m., to avoid excessive evaporation. How often should […]
  • Trees can recover from storm damage. Oftentimes, storms leave trees looking bare and deflated but looks can be misleading. Before deciding that your storm-damaged tree can’t be saved, ask yourself:  If the tree is healthy, not a hazard, and didn’t suffer major structural damage, it will usually recover if you apply first aid measures right […]
  • After a storm, your first thought might be to get things cleaned up as quickly as possible. However, hasty decisions can often result in removing trees that could have been saved.   Ask yourself the question,  Can My Tree Be Saved?  Knowing what to do for your trees can make the difference between loss and survival. […]
  • Planting and establishing trees is about managing air and moisture in the soil. Manage these correctly and trees will grow quickly following planting.   Three of the most common causes of poor tree establishment or death are planting too deep, improper watering, and girdling roots.   If appropriate species are planted at the right depth and irrigated […]
  • When applied and maintained correctly, mulch has many benefits for trees. It conserves water, reduces weeds and competition from other plants, and can regulate soil temperature. Keeping soil warmer in the winter and cooler in the summer. Organic mulch also helps soil by encouraging helpful microorganisms, which can improve soil over time.  However, if mulch […]
  • Most landscape trees do not need fertilizer. It’s better to focus on watering and mulching to help your trees grow. Instead of chemical fertilizers, consider spreading a thin layer of compost on the soil each year to improve soil health and add nutrients. Compost can be added underneath mulch.  If you think your soil might […]
  • Tree decline is when trees gradually lose vigor and display pale green or yellow color leaves, small leaves, poor growth, early leaf drop, early fall color, or dieback of twigs and branches. These symptoms observed above ground usually indicate problems in the root system.   Stress factors Some decline is caused by specific diseases and […]
  • Our Community Forestry Program focuses on building local capacity to help communities develop sustainable programs that provide Texans with healthy trees and forests.   Texas continues to be one of the fastest growing states in the nation. Trees provide many benefits to growing communities including improving air quality by filtering pollutants, reducing heat, and helping to […]
  • Trees provide many economic, social, and environmental benefits that lead to improved well-being and a better quality of life.   While it may be intuitive that living near trees and associated greenspace encourages general feelings of well-being, numerous studies substantiate the connection between healthy trees and healthy lives.  The value of traditional goods and recreational opportunities, such […]
  • Pruning is one of the most common maintenance practices. Trees growing in a forest grow well without pruning, but landscape trees often require more attention. Each pruning cut is a wound, therefore, if done incorrectly, pruning can harm trees and even shorten their lives. However, when done right, pruning helps trees stay healthy, maintain good […]
  • Young and newly planted trees need particular care and attention to increase their chance of survival. Especially in the cold. Though Texas is not known for harsh winters, the winter season can still be tough on trees as evidenced by Winter Storm Uri in February 2021. Harsh conditions like cold winds, bright sun, bitter ice, […]
  • Severe drought has long-term impacts on trees. Stress may linger for years, long after soil moisture returns.   In many cases, drought kills the fine feeder roots that trees use to take up water and nutrients. Until these feeder roots can be fully replaced, the tree remains under stress and cannot support a full canopy of […]
  • During a drought  During a drought, the lack of water causes trees to photosynthesize less, or make less food, which leads to a lack of nutrients needed to survive.   Plants generate their own food through photosynthesis and one of the key components of photosynthesis is water. Water is necessary for the chemical reactions that create […]
  • Forests provide the cleanest water of any land use. And as Texas’ population increases and forests and woodlands decrease, our water supply is at risk. Texas forests This process is known as the forest-water relationship, or watershed ecosystem services, and is valued at $13.2 billion annually.   Partnerships and best management practices are used to enhance […]

Book 100 of these trees have […]
  • Invasive species like the emerald ash borer and laurel wilt have become significant threats, killing native trees and disrupting ecosystems. Additionally, multiple stressors such as native pests, diseases, and environmental factors compound, can lead to the slow weakening and eventual death of trees.   Texas’ extreme climate, with high temperatures and prolonged droughts, intensifies tree stress, […]
