Orange trees suffer if they receive either too much water or too little. They must be planted in well-draining soil. To give them the right amount of water, you need a shovel and a hose.
- Create watering rings
Use a shovel to build watering rings about 8 inches high and 2 feet wider than the canopies of the orange trees. This keeps the water where it is needed.
- Water the trees thoroughly
The root systems should be soaked thoroughly with each watering. Depending on the size of the trees, give them 5 to 10 gallons of water each. Young trees need more water than mature ones. Give newly-planted trees water every 3 days. Once they are a few months old, water them every 5 days. When they reach 4 months, watering once or twice a week is sufficient. Check the moisture level with your finger. If the soil feels dry 3 to 4 inches down, it is time to water again.
- Apply mulch
A 2-inch layer of mulch around the trees helps prevent loss of moisture. Use wood chips, shredded leaves or pine needles for mulch.
- Watch for signs of over-watering
Orange trees can die if you give them too much water. Watch for signs of over-watering such as curling leaves, pale or yellowish leaves, feeble growth or split fruit. If you notice these indications, let up on the watering.
