When you think of peaches you may instantly think of Georgia, but they actually have been grown in Asia for 2,000 years. Within the last few centuries they were introduced to the United States and have been grown here ever since. Peaches need full sunlight and regular pruning to thrive. Watering is crucial, especially when they are setting fruit since 87 percent of the fruit volume is water. The last 30 days before harvesting is the most critical since peaches attain 66 percent of their final volume during this period.
Apply 7 gallons of water per peach tree per week throughout the months of April and May during its first season in the ground. Spread the water out over the entire root zone, which extends from the trunk to the edge of the tree's canopy.
Increase the water provided to each tree to 14 gallons per week in the month of June during the first season. During July and August the tree will need 28 gallons of water per week.
Apply 14 gallons of water per peach tree per week in the months of April and May during the tree's second and subsequent seasons. Increase this to 28 gallons per week in June and up to 56 gallons per week in the months of July and August.
Apply supplemental rainfall in September and October only if rainfall is below average. The tree's root area should receive 21 gallons per week in these months the first season and 28 gallons per week during the second and subsequent seasons.
