Culture
Grow in average, medium moisture, well-drained soil in full sun. Self pollinating. Benefits from regular watering, fertilization and pruning. Plant in full sun in a site where periodic chemical spraying will not pose any problems to adjacent areas. Avoid planting peach trees in the same soil where other stone fruits have recently grown. Hardy in Zones 5-8. The rootstock of a given cultivar will affect its cultural needs, tolerances, and hardiness.
'Bonanza' is hardy in Zones 6-9.
Noteworthy Characteristics
Prunus persica, commonly called peach, is native to China. It is grown for its luscious fruit but some cultivars are grown chiefly for their showy, fragrant flowers and produce inedible fruit. Species trees grow up to 25' tall and wide but peach trees sold in commerce today are grafted to rootstocks which control the size of the tree. Dwarf trees bear standard size fruit, but have the advantage of fitting into smaller sites and being more manageable (easier pruning, spraying and harvesting).
Genus name from Latin means plum or cherry tree.
Specific epithet means Persia. Prunus persica reached Europe from China through Persia.
'Bonanza' is a dwarf, self-fertile peach that will reach 5-6' tall with an equal spread (smaller if grown in a container). The bright pink, fragrant, semi-double blooms cover the branches in early spring and are followed by full-sized peaches. The fruits have orange to red skin and sweet, flavorful, yellow flesh.
Problems
Peaches are susceptible to a large number of serious pest problems. A regular regimen of chemical spraying is needed in order to insure harvesting a good crop. Potential disease problems include peach leaf curl, brown rot, bacterial leaf spot and canker. Potential insect problems include peach tree borer, plum curculio, oriental fruit moth, root nematodes, mites and aphids. Very cold winter temperatures and late spring frosts often cause significant damage to the buds/flowers of peaches.
Uses
A good dwarf plant with an edible fruit for smaller gardens and large containers.
