The Bonanza Dwarf peach tree is in the Rosaceae family of trees. It is a deciduous plant that prefers humid, moderately warm climates. Its optimal USDA hardiness zones are 6 to 9. This tree grows best in sandy loam soil, as it likes a well-drained bed. The Bonanza Dwarf peach tree will thrive best in full sun.
Water the tree every three to four days. The Bonanza Dwarf peach tree prefers the ground to completely dry out before its next watering. Check the soil. If it is dry to a depth of 2 inches below the soil line, then it is time to water. Deep water the tree by filling its well with water and allowing it to absorb completely. Repeat this process again for a thoroughly deep watering.
Rake up any debris or plant matter under the tree. This plant matter can carry diseases and pests that could potentially harm the tree.
Apply a slow release fertilizer. Read the manufacturer's directions to determine specific dilution amounts of the fertilizer. Sprinkle the slow release fertilizer around the base of the Bonanza peach tree. Follow the sprinkling with a deep watering, this process will aid the fertilizer in sinking deeper into the soil. Do not apply the fertilizer during its first year, but rather each year after for a great harvest.
Cover the well with one inch of mulch during a dry season to help hold in moisture.
Prune the tree in early spring by removing all dead branches from the winter. You will be able to tell which branches are dead, as they will not have new leaf buds forming on them. Use sharp pruning sheers and clip the frost damaged branches back to wherever the frost damage ends. Remember that frost damaged limbs will not regrow, so they must be removed to create room for new growth.
