SITE SELECTION AND CORRECT SPACING FOR PECAN TREES
Well-drained, deep soils are preferred, but pecans will grow on many soil types. Trees will grow more vigorously and produce more nuts in full sun. Two are required for pollination
SPACING Pecans mature spread can require a spacing of 60×60 foot. It does take a long time for trees to mature to this spacing, so often trees are planted on 30 foot spacing .
GETTING THE SOIL RIGHT AND PLANTING PECAN TREES

Pecans prefer slightly acid soil (pH
5.5-6.5). If you are in doubt about the acidity of your soil, take a sample to the Cooperative Extension Agent in your county for a soil test.
Dig a planting hole approximately three times the width of the pot and at the same depth as the root ball. Enrich the planting hole with acid mulches like peat moss or rotted pine bark mixed with soil dug from the hole (50:50 mix). Remove the plant from the pot, gently loosen the root ball and place in the planting hole. To avoid burying too deep, make sure plant is positioned with the top most roots at the soil line. Fill the planting hole with the mix of soil and organic matter; gently tamp it in. Water thoroughly to settle the roots and eliminate air pockets. Do NOT put fertilize in the planting hole. Only apply fertilizer if it is the correct time of year (see Fertilization section below).
If desired, construct a water basin around the base of the tree approximately 36 inches in diameter. Mulch in spring and summer with approximately 4-6 inches of mulch. Pull mulch a couple of inches away from the trunk for good air circulation.
