New Jersey ranges from United States Department of Agriculture (USDA) Hardiness Zones 5b through 7b, with most of the state falling squarely in Hardiness Zone 6. These zones are generally very good for fruit production; to that end, many types of fruit are very easy to grow in New Jersey.
Peaches are easy to grow in New Jersey. Peaches require soil that drains well and full sun. Once your tree is planted and established, you only need to prune and water. By pruning back your peach tree by one-third each winter, you tree will be healthier. Healthy trees produce better fruit with fewer problems. Peach trees are easy to care for, but only live for around 20 years. Older trees can sometimes have more issues with diseases and other problems. Peach trees can produce between 30 and 50 pounds of fruit per tree.
Apple trees also require full sun and soils that drain well. By growing smaller cultivars, like dwarf and semi-dwarf trees, you will not have to prune your mature trees much. On larger trees, winter pruning may be necessary to improve yields. Although growing apple trees in New Jersey is easy, getting high quality fruit from the trees can be difficult. If you find one of the many apple parasites on your tree, you may need to spray for pests. However, with care, growing apple trees in New Jersey is very easy. Some cultivars of apple trees can live over 60 years. Dwarf apple trees can produce between 10 and 20 pounds of fruit. Full-size trees can produce over 100 pounds of fruit.
Like other fruit trees, apricots grow best in full sun and in soil that drains well. Apricot trees live around 20 years and most varieties only grow to about 15 feet tall. Apricots awaken quickly after winter. Some years, their buds can be damaged by a sudden late frost. However, apricot trees are very easy to grow. In years when the frost cycle is conducive to apricot production, an apricot tree can produce between 30 and 120 pounds of fruit per year.
