1 All trees, no matter how tall, have shallow roots. They go out, not down. Even a big tree's roots rarely go further down than 6.5ft (2m) and most are in the first 23.5in (60cm). 2 They rarely find their way down the water table but rely on rain water. 3 Roots anchor the tree and draw in moisture.
Starting 3 feet from the base of the tree, drill 2-inch diameter holes into the soil about 1 to 1-1/2 feet deep. Drill the holes in a circle 3 feet away from the trunk, spacing them two feet apart, then go out 5 feet and drill again in a circle. Continue every 2 feet within the protected root zone (see figure 5).
