Trees need plenty of water, general care to survive dry, hot conditions

Slow-release watering bags help make watering trees more efficient and prevent water runoff.

Watering is the most important summer tree care task.

D.C.’s notorious summer heat has finally arrived and if we have a repeat of last year's conditions the District’s trees will need all the help they can get to survive the season. Casey Trees’ Summer Almanac contains important information to ensure trees are health:

  •     Practice 25 to Stay Alive. Watering is the most important summer tree care task. Residents are encouraged to water trees on and surrounding their property the recommended 25 gallons of water — approximately 1.5 inches of rainfall — per week to survive and thrive. Use a slow-release watering bag that holds the recommended amount of water or improvise with buckets with holes in the bottom.
  •     Mulch. Mulching helps keep the soil moist and controls weeds. If you did not mulch in spring, now would be a good time. To prevent trunk decay, apply using the “3-3-3 Rule” — three inches of mulch in a three-foot ring with a three-inch space around the tree trunk. Avoid improper mulching techniques, such volcano mulching.
  •     Weed. Remove summer grasses from around the trunk.
  •     Install trunk guards. Weed whackers and lawn mowers can cause severe damage to a tree’s circulation system. Add tree guards to the base of the tree if landscaping equipment is used around the tree. Check installed tree guards to make sure they are installed properly.

Each week, Casey Trees issues watering recommendations on its website homepage and Twitter and Facebook accounts. Individuals who live within 25 miles of the District can sign the 25 to Stay Alive watering pledge to receive a complimentary rainfall gauge. Ooze Tubes are also available for purchase online through the Casey Trees shop for $10 each.

Step-by-step instruction on how to properly plant and care for trees is available on the Casey Trees website.
