We’re not the only ones suffering from the record heat — many trees, including those that have been recently planted around the city, are suffering from a lack of water. For advice, DCist turned to Casey Trees, which is our go-to source for all things arbor. According to Casey, trees need about 25 gallons of water a week to live healthy, oxygen-creating lives. Casey recommends applying water slowly, so that the roots of the tree can absorb it. Even with thunderstorms scheduled to roll into the area over the next few days, the heat wave has dried up the soil and your favorite shade-providers still could use a drink. Living in an apartment building and hose-less? Check with your building’s maintenance staff to see if they wouldn’t mind sparing a little water for your leafy neighbors. After all, without trees, it’d be even hotter around here.
