The “Panamint” nectarine tree (Prunus persica nucipersica) is just a self-fruitful stone fruit tree that grows in U.S. Department of Agriculture plant hardiness zones 5 through 9. Since it’s self-fruitful, just one tree is essential. “Panamint” nectarines develop to 25 feet tall with an equal spread. They require fertile, well-draining soil and full sunlight for good fruit production. The tree blooms in February or March, with fruit ready to choose at June or July.
Plant multiple trees at least 10 to 12 feet apart to provide them sufficient space so that they do not grow into each other or compete for nutrients. Since the trees are self-fruitful, they don’t need to be close with cross-pollination functions.
Preserve the trees at least 12 feet in structures like homes so the canopy does not grow into the face of the home or over spaces such as pools or driveways. With a 25-foot canopy, the branches will grow about 12 feet in the back.
Leave 12 to 15 feet of space between the trees along with any underground ducts or pipes that could be damaged by the tree roots. The roots will spread a little past the drip line of the tree canopy, so additional space is necessary under ground for roots to spread.
