Planting Trees in Lawns
Planting fruit trees in a lawn is fine; just remove the sod in a circle 3 or 4 feet out from each fruit tree, and mix some compost or other organic matter into the whole area. If the lawn contained many broad-leaved weeds, test the soil for nematodes and follow the instructions above for planting marigolds. Eliminate any noxious perennial weeds such as quack grass. Remove competitive grasses such as Bermuda or zoysia from the entire area that the fruit trees will ultimately occupy, and replace them with less competitive groundcovers. Do not replace an old fruit tree with the same or a closely related type of fruit. Not only have nematodes and other soil-borne diseases built up, but the roots of certain fruit trees, such as peaches, exude a toxin that inhibits the growth of new peach roots. Don't place new stone fruit trees right next to older ones, to prevent the spread of non-curable diseases such as X-disease or cherry yellows.
