Rare Dwarf Peach Fruit Tree "10 Seeds" Peach trees can be pruned more severely than other fruit trees, especially those with foliage as thick as the dwarfs. Dwarf Peach need only four to five weeks of chilling temperatures and they thrive in warm, hot summers. If you live in a region with cool, wet springs, peaches might not perform well because their blossoms fail to pollinate under these conditions. Home gardeners find definite advantages to growing dwarf peach trees. Since many genetic dwarfs only reach 6 feet tall, compared to standard varieties that may be 25 feet high and as wide, ladders are unnecessary for pruning and harvesting. Peach Dwarf fruit trees are a boon to the modern gardener. They take up much less space than standard trees and they're simpler to maintain, prune and harvest. Peaches are not usually grafted to a dwarf rootstock, but are naturally small trees, rarely growing taller than 12 feet. Peaches are self-pollinating and don't require two trees for pollination.
