Pomegranates resemble shrubs but are actually tropical trees. A deciduous plant, the tree has dark green leaves and produces pomegranate fruit in late summer and early fall. The tree is prized for the fruit, which has ruby-red edible seeds inside a thick rind. Pomegranates grow only in areas with mild winters, because they don't tolerate extended periods of freezing temperatures. Watering the pomegranate tree properly is necessary to ensure that the plant thrives and remains productive.
Build up a ring of soil that is 3 to 5 inches high and of equal thickness around the trunk of the freshly planted tree. Build the ring 2 feet out from the trunk of the pomegranate.
Turn the hose spigot on fully, then fill the space between the ring and the tree trunk with water. Continue watering every three days for two weeks, filling the space inside the ring with water. The water will seep into the soil and thoroughly moisten the soil in the root zone of the tree.
Reduce watering to once a week beginning in the third week. Continue watering at this rate for the first year or until the soil ring has broken back down to ground level.
Water the tree as needed once it's established or beginning in the second year. Water once weekly during hot, dry periods in summer or when the pomegranate is in leaf.
Apply a 2-inch layer of mulch around the tree after the soil ring has broken down. Mulching preserves soil moisture between waterings. Apply the mulch so it covers an area around the tree equal to the diameter of the tree's canopy.
Things You Will Need
- Pomegranate trees require approximately 60 inches of moisture a year, including rainfall. Because they are deciduous trees, most additional irrigation should be provided when the trees are in leaf and actively growing and not when they are dormant.
- Pomegranates can tolerate some over-watering, so err on the side of too much water when determining irrigation amounts.
- Once fruit has set, the soil around the tree must be kept evenly moist or the pomegranate fruit may split open prematurely.
