On an average of once every 8 years, winter temperatures can fall well below this, resulting in crop loss and serious damage to the trees. Sometimes peach and nectarine trees are grown underneath roof overhangs on the south wall of a house to give some winter protection. Peaches and nectarines should be planted in areas where spring frosts are rare. Summer temperatures should be high with low relative humidity. Peaches and nectarines are hardy in Zone 6, marginal in Zone 5 and very risky in Zone 4.
Good air drainage is needed. Peaches and nectarines grow best in a deep sandy loam or silt loam soil. Peach and nectarine trees are smaller than most other fruit trees and as such lend themselves to small lots. An area with a minimum diameter 15 ft. (4.6 meters) is recommended for each tree.

All peaches are self-fertile except J.H. Hale.
Select a well grown one or two year old tree from the nursery. Two year trees should have at least four or five well-spaced branches with a good root system. The usual practice is to plant early in the spring, but planting can be completed in the fall when weather conditions are good and the soil is moist. Prepare a hole slightly larger than the root spread. Trim off any broken roots before planting. If the tree is in a plastic pot, remove the pot. If it comes in a fiber pot, you can slit the sides and plant with the pot or remove the pot. Sprinkle a handful of bone meal (phosphorous) in the bottom of the hole to help the root system get established. Place the tree in the hole. Mix in soe peat moss or compost with the planting soil. Replace the soil in the hole, treading the soil firmly around the roots to ensure that the tree is securely anchored in the ground. Give the tree a good watering. An area of about 4 ft. in diameter (1.2 meters) should be kept free of weeds or lawn grass during the early stages of growth. Organiz or plastic mulches can also be used to suppress weed growth around the tree.
At planting time, cut the one year tree back to a height of 33-36 " (82.5-90 cm). If a two year old tree is planted, reduce the branches to four well-spaced shoots and shorten each by one-third, weak side branches should be removed. Peach trees and nectarine trees are usually grown as open center trees with the central leader removed. Aim to develop a framework of well spaced branches that are capable of bearing heavy crops without breaking. After about three years the scaffold branches are well established. Young trees should make 18 inches (46 cm) of new growth annually. Mature trees should have 16 " (40-45 cm) of new growth. Peaches and nectarines do not produce fruit on fruit spurs. The fruit is produced on one year old wood. In order to have lots of new growth for next year's crop, the trees are pruned harder than other types of fruit trees, with lots of heading cuts. No peach tree should be allowed to grow more than 14 ' tall (4.3 meters). Many commercial peach and nectarine growers keep their trees at about 10' tall (3 meters). A renewal program of heading back and thinning out of some main branches each year will encourage development of new fruiting wood lower down in the trees. Only 75% of the previous year's growth is left to bear fruit the next year.
SOIL & FERTILIZER
Soils in the Southern Interior are chronically low in organiz matter and nitrogen. Minor elements such as magnesium, boron, and zinc may be low as well. If good weed control is practised, no fertilizer should be required for the first two or three years. When the tree starts to crop, apply one ounce (28 grams) of a complete fertilizer such as 12-16-12 (which contains minor elements) per square yard (0.8 sq. meters) in the fall. Nutrients can also be applied as foliar sprays in early summer. Organiz growers should use approved sources of organiz nutrients.
Under normal conditions peach and nectarine trees set more fruit than the tree can possibly support. Some of the fruit must be removed in order that the fruit that is left will develop to a good size and also that branches will not break. Thinning keeps the peach tree vigorous and productive. Fruit should be thinned to about six inches apart (15 cm). Thinning is done in June.
The fruit on peach and nectarine trees will not all mature and ripen at once. This means that the fruit on the trees must be examined carefully and the mature fruits are picked while the other fruit left on the tree to gain size and color. Three to five pickings may be needed, with about four days between each pick. A peach is fully mature when it has grown to full size. At that time the fruit starts to ripen. The fruit begins to soften and develop juiciness and flavor. The ground color of the skin changes from green to yellow and the pit begins to turn brown. The fruit should be picked when they are firm ripe or soft ripe. Tree ripened peaches and nectarines have excellent flavor but lose their good smooth texture.
PESTS & DISEASES
The most common pests of peaches and nectarines are: Peach Twig Borer, Peach Tree Borer, Lygus Bug, Earwigs, and Green Peach Aphids. The most common diseases are: Peach Left Curl, Coryneum Blight, and Brown Rot. Check the "Gardeners Guide to Fruit Tree Sprays" published by the BC Ministry of Agriculture and Food, or consult the B.C.M.A.F. publication "Pest Control For The Home and Garden." Organic gardeners should use accepted organic control methods.
