The recent heat wave is a good reminder to take extra care of our plants as temperatures climb. Proper watering is always important but even more so during extreme heat.
Water plants thoroughly when the top few inches of soil are crumbly and moist. Plants will develop deeper roots that are able to access water from a larger area, making them more drought tolerant and pest resistant. Avoid frequent, light watering that encourages shallow roots more susceptible to drought stress. Make sure new plantings, moisture lovers, and stressed plants are the first to receive a good long drink.
Don’t overlook established trees and shrubs that need a helping hand during extended periods of hot, dry weather. Soak the area under the tree’s dripline when the top 4 to 6” of soil are crumbly and slightly moist. Provide 10 gallons of water per inch diameter of tree trunk measured at 4½ feet high.
Water early in the day, when possible, to reduce moisture loss to evaporation. Use soaker hoses and drip irrigation whenever possible. You’ll use less water by applying it right to the soil where it is needed.
Mulch the soil to conserve water, keep plant roots cooler, suppress weeds, and improve the soil as it decomposes. Spread a one-to-three-inch layer of leaves, evergreen needles, woodchips, or other organic matter over the soil surrounding plants. The coarser the material, the thicker the layer of mulch needed. Pull mulch away from the trunks of trees and the stems of shrubs and other plants. You obtain multiple benefits from this one task while burning a few calories and strengthening your muscles.
