Summer can be one of the most challenging seasons for landscape plants, with heat and drought posing significant threats. Insufficient moisture makes plants more vulnerable to insect infestations and diseases, with trees being especially at risk due to their value and difficulty to replace. Prioritizing tree care during drought periods is essential to maintaining a healthy landscape.
Recognizing Drought Stress in Trees
Not all dry conditions indicate drought stress in trees. Many trees have deep roots that help them withstand short dry spells. However, prolonged lack of moisture can cause visible signs of stress. Deciduous trees may display wilting and curling leaves, browning edges, and premature leaf drop. Evergreens show browning at needle tips, which can spread to entire needles if drought persists.
Which Trees Need the Most Attention?
Newly planted or transplanted trees are most vulnerable due to underdeveloped or damaged root systems. Trees in confined spaces, such as containers, narrow grass strips between streets and sidewalks, or near buildings and driveways, also require extra care due to limited root expansion and additional heat stress. Drought-sensitive species like birches, beeches, dogwoods, Japanese maples, and magnolias should be prioritized.
Effective Watering Practices During Drought
Prevent drought stress by establishing proper watering routines early. Trees need about one inch of water weekly, provided naturally or through supplemental watering.
For optimal results, water deeply and slowly in one session. Use irrigation bags for young or newly planted trees. Trees in confined spaces benefit from a slow-dripping hose at the base, repositioned periodically for even coverage. For larger trees, a soaker hose arranged in a spiral from the trunk to the drip line is effective.
Always adhere to local watering restrictions during drought periods to avoid fines while keeping your trees healthy.
Additional Tips for Drought-Stressed Trees
- Water soil directly, not the leaves or needles.
- Apply 2-4 inches of mulch under the tree, from the trunk to beyond the drip line, to retain soil moisture. Keep mulch away from the trunk.
- Water early in the morning, late afternoon, or on overcast days to reduce evaporation.
- Avoid fertilizing during drought; opt for compost or gentle soil amendments instead.
