Summer Tree Care Tips from Brookland Based Casey Trees

Summer has put a tight grip around our area. Although we have had more rainfall than average, it is still helpful to review a few tips that Casey Trees published in their tree almanac. Following these guidelines will help especially your young trees to make it through the hot summer. Please do not forget about the many new trees in our neighborhood that were planted by the city, i.e. along 12th Street. They need your help as well. Consider investing in a watering bag to make it easy for you to give a young street tree the sufficient amount of water per week, or a tree guard to protect the trunk from lawn movers and weed whackers.

Here is an excerpt from Casey Trees website:

There are a variety of ways to help water your trees:

  • Pledge to water your trees through our #25toStayAlive campaign and we will mail you a complimentary rain gauge for your yard. If less than 1.5 inches of rain falls in a week, you know to water your trees. (Offer limited to those within a 25-mile radius of the District.)
  • Follow our weekly watering recommendations. Every Monday from May through September, we post tree watering recommendations here, on our homepage and to Facebook and Twitter. Tweet @CaseyTrees with the hashtag #25tostayalive or send us a message on Facebook to let us know how your watering efforts are going.
  • Purchase a slow-release watering bags to help make watering your trees easier – 25 gallons, once a week. They’re available for purchase on our online shop for $15 each.

Also, here’s some other advice for District residents –

  • Mulch. Mulching helps keep the soil moist and controls weeds. If you did not mulch in spring, now would be a good time. Apply the “3-3-3 Rule” – three inches of mulch in a three-foot ring with a three-inch space around the tree trunk to prevent decay.
  • Weed. Remove summer grasses from around the trunk.
  • Check 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. They’re available for purchase on our online shop for $3 each.

We have additional resources in our Trees How-To section of our website – look for our tree care tips as well as our video instructions for how to water and prune a tree.
