Selection and Care of Bare Root Fruit Trees


Winter is the time of year to choose your bare root fruit trees. Many
nurseries stock a wide variety of trees and it is helpful to go shopping armed with some knowledge of what grows best in your area. The most important consideration in choosing fruit trees is chilling hours. Fruit trees need a certain amount of chilling hours, below 45 degrees, and between November 1 and February 15th, in order to produce fruit. The inland portions of our county have no problem producing enough chill hours. If you live along the immediate coast, where the winters are milder, you will need to choose low chill hour varieties, ones that need 400 chill hours or less.

Some fruit trees require cross pollination with another tree to produce
fruit. Be sure to choose a self pollinating type or buy two compatible varieties. Your nursery should be able to help you select what is best for you.

Fruit trees are grown on many types of root stocks. Some are resistant
to certain diseases, some tolerate different growing conditions, and some grow to different heights. Often there is no choice, but a well stocked nursery will have trees on different root stocks.

Plant your bare root trees as soon as you get them home. Dig a hole big
enough so the roots are not cramped, but be sure not to plant the trees too deep. It is important that the graft union is 2-6 inches above the soil line. Form a basin around the hole and water thoroughly. Paint the trunks with a white latex paint to avoid sunburn.

If you have a limited space for your orchard, try planting several trees
in the same hole, or purchase multiple budded trees. You can buy fruit trees that will produce plums, peaches, nectarines and apricots on the same tree. Trees can be planted as close as 30 inches apart or try an espalier type of pruning. Summer pruning will keep your trees from getting too big and most importantly, keep your fruit within reach.
