Common Questions About Trees
How can I tell if Ive picked a site with good drainage'
Start by digging a hole as deep as your planting hole. Fill the hole with water and watch to see how water drains from the hole. If it drains at a rate of less than 1 inch per hour, pick a new site. If thats not possible, consider installing some form of drainage to carry water away from the base of the tree. Also consider using water-tolerant species, such as:
Red maple
Sycamore
willow oak
river birch
How big should the planting hole be'
While you might be tempted to dig a very deep hole, in fact a tree requires a shallow planting hole that is no deeper than the root ball. However, it is very important to make sure the hole is wide enough. As a general rule, make yours three times as wide as the root ball. Such a wide shallow hole encourages the horizontal root growth that allows your tree to thrive.
Should I add anything to the soil'
You may be accustomed to backfilling planting holes with peat moss or other organic matter when installing perennials.
