The peach tree (Prunus persica) is a deciduous flowering tree in the rose family and a native of China. There are thousands of varieties of peaches, grown worldwide, with China remaining the largest producer, according to agriculturists with the University of Georgia. The peach tree thrives in regions with Mediterranean climates and is less cold-hardy than other fruit trees. The amount of water you give the peach tree determines the taste of the fruit. Too much water and the peaches will taste bland and flavorless.
Place the soaker hose three feet beyond the peach tree's drip line, which is the area under the widest part of the canopy.
Apply 1 inch of water per week while the tree is in fruit. A soaker hose delivers 30 gallons of water per hour, per 100 feet of hose, according to agriculturists with the New York State Agricultural Experiment Station. Measure the distance from the base of the peach tree to the soaker hose. For every 25 feet in distance, allow the soaker hose to run for 3 1/2 hours per week.
Withhold water if it rains.
Cut the amount of water applied in half after harvest. When the leaves begin to fall, cut the amount in half again.
Water the tree during the winter only if it is particularly dry, with no moisture for one month.
