I want to get a couple of dwarf peach, or nectarine trees and 1 or 2 cherry trees. Is there any reason I shouldn't grow them in the front yard instead of my back yard? I would like something pretty there but I want trees that will give me fruit.
The only caution I've seen regarding fruit trees in the lawn is that if you fertilize the lawn, you must take care not to fertilize the tree roots. Too much nitrogen will give your trees healthy foliage, but no fruit.
It is usually recommended to grow fruit trees in an island bed or garden bed, away from the lawn.
