The Primary Non-pesticidal Strategy

The Primary Non-pesticidal Strategy

All homeowners should consider purchasing and planting backyard fruit trees that are grown on dwarfing or semi-dwarfing rootstocks that will help keep the overall height of the mature tree to between 10 to 12 feet high (Figure 5). In turn, dwarfing rootstock serve to keep fruit bearing zone low and reduce the need of ladders to manage and harvest your homegrown fruit. Regardless of rootstock chosen, overall tree size is best maintained by proper training and pruning.  Even standard-sized trees (that normally grow to 30 to 40 feet tall) on seedling rootstock can be maintained to a height of 10 to 12 feet through annual pruning and training (tying down) of overly upright limbs.  Play video for fruit bagging demonstration.
