irrigate young trees

It is important to be careful that young trees do not dry out, especially during the first growing season. This is a critical time when the root system is being rebuilt from the shock of transplanting. However, homeowners often love their young trees to death by overwatering.  During cool spring conditions, water loss will be minimal, but as the hot, dry summer conditions come, water loss both from the soil surface and through the young trees will increase.  Water thoroughly once per week, gradually decreasing irrigation frequency as the tree becomes established.  In hotter climates, young trees may need to be watered twice per week.
