Planting Fruit Trees, Nut Trees and Berry Plants in New Hampshire.
Numerous kinds of fruit trees can be planted by the New Hampshire home gardener. The NH winter effects the hardiness of the fruit tree that is selected.. Very important other factors that affect a cold hardy fruit tree survival is the consideration to stop fertilizing and NO fall or winter pruning of the N.H. fruit trees. It is important to plant healthy fruit trees that should normally experience little or no growth as the winter approaches. Many N.H. gardeners paint the trunks of the fruit trees with a whitewash or a lime-water mixture to reflect the light away from tree trunk when the thawing takes place during the winter “Indian Summer.” Harm can occur on the fruit tree trunk of twigs from sun scald and can damage the tree trunk.
Peach trees such as the Hale Haven and the Red Haven Peach tree will grow well in Southern New Hampshire and can survive cold hardy temperatures of minus 10 degrees F. Plum trees such as Ozark Premier, Methley and Burbank will show cold hardy tolerance in New Hampshire orchards and native (wild) plums show perhaps the highest cold hardiness in southern and central New Hampshire orchards Apricot trees can produce crops of apricots in the same zones as peach trees and plum trees. Cold hardy pear trees can only be grown in southern N.H.
Sour cherry (tart) trees are much more cold hardy than sweet cherries, however, the sweet cherry, black tartarian cherry tree can be planted in Southern New Hampshire. The red Montmorency cherry and the North Star cherries can be grown to be used as pie (sour) cherries successfully.
Shade trees such as Red Maple shade tree and Sugar Maple shade tree can be easily grown to shade New Hampshire homes and drastically cut electric bills during the summer. Many N.H. gardeners prefer to plant native trees as useful shade trees, because centuries of repeated survival the tough winters cold frigid temperatures has proven their cold hardiness.
Many berry farmers in New Hampshire plant either native blueberry plants or improved blueberry plant cultivars. Red raspberry organic plant farms are very productive and the black raspberry or purple raspberry plants will show some cold hardiness in sheltered southern N.H. sites.
Nut trees such as filberts or American Hazelnuts nut tree will survive in orchards in NH. Some black walnut trees have produced nuts in New Hampshire, but most often, the white walnut or butternut is a favorite nut tree that produces reliably. Some Chinese chestnut trees have been shown to produce chestnuts in New Hampshire, but the American Chestnut tree, now with blight resistant traits, is successfully growing in New Hampshire nut orchards.
Tropical plants and fruits such as banana trees, pomegranate trees and fig trees have produced bananas, pomegranates and figs in New Hampshire greenhouses when grown in side glass during extended cold periods. Other popular indoor greenhouse fruits in N. H. are persimmon and guava trees.
