After planting young trees, prune the top of each tree. Pruning the tree top balances the root system and promotes vigorous growth in the spring. When working with unbranched trees, cut the tree off approximately 32 inches above the ground. Weed Control Weeds or grass growing between or under fruit trees compete for soil nutrients and moisture, reducing tree growth. Avoid using mechanical cultivation to eliminate weeds because tree roots near the surface will be destroyed in the process.
Weed whips are especially harmful.
If the cutting line strikes the bark of the tree, it can crush layers of cells under the bark and girdle the tree without any visible signs, such as broken tree bark. Herbicides are an effective alternative, but be careful to follow the label directions and keep the herbicides off the tree. Another alternative is to mulch around the tree. A layer of mulch 4 to 6 inches deep will control weeds and conserve soil moisture. Note, however, that mulch can provide cover for voles or mice.
