This question is popular, and the answer is full of details to consider.

Tree Species. Knowing the type of tree you have will help you determine how much water the tree needs to develop correctly. However, some trees might not even be adapted to the West Texas environment, and regardless of how much water you provide, they will still struggle. Native and adapted tree species are highly recommended.

Tree Age and Size. Mature trees (decades old), already established trees usually need deep, infrequent watering. Newly transplanted trees will require more frequent watering. 

Know your soil type - a soil test comes in handy here! Clay soil holds water longer but drains slowly, so water less frequently but more deeply. Sandy soil drains quickly and may require more frequent watering. Loamy soil (ideal) holds moisture well while still draining.

Identify the "drip line". Tree roots extend well beyond the canopy; this is the drip line area. Watering just at the trunk misses most of the absorbing roots. Water the drip line and focus on areas under and beyond the canopy.

Weather Conditions/Seasons. In hot, dry, or windy weather, water more frequently. Trees will need more water in summer due to heat and active growth. In fall and winter, watering is reduced, but watering is not stopped entirely in dry climates as roots remain active.

Quick Facts for watering established trees and shrubs (from University of Minnesota Extension):

• Water established trees and shrubs with overhead sprinklers.

• Apply a deep watering over the entire root zone area until the top 6 to 9 inches of soil are moist.

• Avoid light watering as this promotes shallow root systems that are susceptible to summer heat and drought stress.

• Water early in the morning to minimize water loss due to evaporation and wind drift.

• Mulching around the base of trees and shrubs helps them take in water and stay healthy.
