Prunus persica ( Peach )
Originally native to China; its actual place of origin is enshrouded in mystery after centuries of cultivation. Typically a small tree to 20 feet; some records include: fastest recorded growth rate - 4 feet; 4 years - 11 x 6 feet; largest on record - 60 x 40 feet with a trunk diameter of 2.5 feet.

The large, showy pink or white familiar early spring flowers appear before the foliage.
They are followed by the yellow to red down covered tasty, large, edible round fruits up to 3 inches long.
The twigs are reddish with white, fuzzy buds.
Hardy zones 5 to 8 ( use hardiest seed source/cultivars only in zone 5 ) in full sun on acidic or alkaline, humus-rich, well drained soil. Kept the ground beneath the tree either bare or better yet mulched in organic matter, turf grass on top of tree roots will slow your Peach trees growth and production considerably. When buying a Peach tree, it is best to buy approx 4 foot tall 1 year bare root trees and plant during early spring while still dormant. It is important to but from a reputable nursery that can guarantee the tree and the rootstock ( Lovell & Siberian C are common ) is true to type and is free of nematodes or viruses. Selecting the right variety can make all the difference between success, failure or a tree that needs more chemicals than it is worth. Peaches thrive over a very large range of climates however different cultivars fare better in some than others. Peaches are self-fertile, not needing multiple trees to produce fruit. Peaches may be prone to peach leaf curl in some regions. Canker is a problem in humid areas, it is recommended to not use canker prone root stock where this is a problem and immediately prune dead wood out of trees where it may occur. White plastic trunk wraps can be used to protect the trunk of peach trees from sunscald. A deep weekly watering is recommended if drought occurs during the time between flowering and the fruit ripening. Propagation of cultivars is from softwood cuttings taken during summer.
