Irrigating fruit and shade trees and shrubs
Different types of plants have different water needs. Too much or too little water damages or kills plants. Watering too frequently is common in established gardens and landscapes. Underwatering of the root zone is common in new plantings.
Learn and follow the irrigation rules of your water supplier, such as drought-related watering restrictions. If lawn watering is curtailed, trees and shrubs that rely on water applied to turfgrass may decline or die without supplemental irrigation.
