Peaches and nectarines can be grown throughout Delaware. Plant trees in full sun and on well-drained soils. Trees are subject to winter injury and late spring frosts. Do not plant trees where water will stand for 3 or more days after a rain. Irrigation is not needed except during prolonged dry periods.
Water is needed most during the fruit-sizing stage.
Normally, no water is needed during the ripening stage unless there is a drought. Trees will occupy a space 15 by 20 feet if kept pruned. Order trees in December for March and April planting. Dwarfing rootstock trees are short-lived. If trees can't be planted immediately, open the bundles as soon as they arrive and soak the roots in water for a few days.
