Besides watering, mulching is the next best practice you can use to help your tree survive and thrive. Mulch holds moisture in the hot summer, keeps down weeds, and improves soil conditions as it decomposes. Always use natural, undyed mulch made from wood chips. When putting the mulch around your tree, don’t let it touch the trunk. Mulch should be a maximum of 2-3 inches deep with an open space in the middle. Aim for a mulch donut, not a volcano! A buried tree trunk will start to decay and can limit the lifespan of the tree.

A newly planted tree requires about 20 gallons of water each week between May-October. Rain is only a substitute for watering if we get a one-inch rainstorm or more. Baltimore Tree Trust will care for trees for the first two years after planting, which includes routine watering. However, if Maryland is experiencing a severe drought or you notice browning/wilting/curling leaves or premature fall coloring, this may be an indication that your tree is stressed. You can help a nearby tree by watering it yourself.

The best way to water newly planted trees is to go slow and allow the water to penetrate deep into the soil. This allows the water to reach 8-12 inches into the ground instead of just wetting the surface. Slow watering encourages deeper root growth, which leads to a more anchored mature tree.

There are several slow drip methods that we recommend including putting your garden hose on low and placing it at the base of the tree trunk for 5-10 minutes (depending on flow rate) or drilling holes in a 5 gallon bucket and refilling it a few times so the water trickles out. You may also consider purchasing products like gator bags or greenwell water savers to install around your tree.

It takes about 2-3 years for most trees to develop the extensive root systems needed to soak up ample rainwater to survive on their own.
