Spring tree care made easy in our Spring Almanac

No matter what type of winter we’ve had in the past weeks and months, March 20 always marks

the official first day of spring. That means it is time to announce our annual Spring Almanac recommendations!

D.C. residents are encouraged to:

  • Install slow-release watering bags around newly planted trees. Practice 25 to Stay Alive by giving trees that have been in the ground less than three years 25 gallons of water, equal to 1.5 inches of rain, a week.
  • Remove winter weeds and emerging grasses from around the trunk base.
  • Add trunk guards if lawn mowers or weed whackers will come near the trees. If you live near locations with deer populations, install deer guards (more info on the topic).
  • Mulch your trees to keep the soil moist, discourage summer weeds and deter pests and diseases. Apply mulch using the 3-3-3 rule — 3 inches of mulch in a 3-foot ring with a 3-inch space around the tree trunk.
  • Inspect for dead or crossing branches. Damaged branches should be pruned carefully (see videos). Dead branches should be removed.

Share our Spring Almanac with your friends, family and neighbors.

And be sure to let us know what you’re doing to care for your trees: take a picture and tweet it @CaseyTrees or visit us on Facebook.

    Can you deliver a new green watering bag to 1310 29th Street NW, Washington DC 20007.

    I think I should have begun watering by now but do not have a slow-release bag. This tree was part of the Georgetown tree project.

    Thanks for your concern for watering your street tree/s.
    We are extremely busy this spring and are not able to drop off a bag just yet. We will be switching gears to watering about mid May. We have ooze tubes to drop off in Georgetown and I estimate that work will be completed by May 25th.
    If you would like a bag before then, please come by our office to pick one up, between 9 and 5. Our office is located at 3030 12th Street NE.
    Thank you,
