Answer: Avocado trees need lots of space and lots of sunshine. The roots of an avocado tree can be encouraged to grow deeply by deep watering so start your tree out right by building a watering basin or watering well beneath it after it is first planted. When you water, fill the basin with water, allow to drain, then fill it a second time. This method of watering will concentrate the moisture over the rootmass and allow it to trickle down, wetting the entire root mass. Avocado trees can drown if the soil drains poorly or you water too frequently. Water once a week (as above) the first year your tree is in the ground; reduce watering (but water deeply) about once every 10 days during its second year. After that, it should only need deep watering about every 2 weeks during the growing season. Best wishes with your landscape!
