The site should be thoroughly watered immediately after planting. Thereafter, the soil must be regularly monitored to prevent drying out. If rainfall is inadequate, the soil around the plant's roots should be deeply watered approximately every 10-14 days. If you are not sure if the soil is drying, dig down 3 to 4 inches next to the plant. Wet soil at that depth verifies watering is not needed at that time.
Mulches help conserve moisture, moderate soil temperature and control weeds around trees and shrubs.
They are placed on the soil surface over the tree or shrub root system. Either organic or inorganic mulches may be used. Organic mulches may be composed of bark or wood chips, straw, partially decomposed leaves or other materials. They should be applied 3 to 4 inches deep. Maintain a 4 to 6 inch mulch-free area adjacent to the woody stems.
