At 3 to 4 years of age, they begin to bear large crops and reach peak productivity at 8 to 12 years. To maintain size and encourage new growth, heavy pruning is needed. Nectarines, as Peaches, require well-drained soil and a regular fertilizing program. Peach leaf curl, peach tree borer, and curculio can be a problem.
