Citrus trees are a hedgelike plant that produces highly acidic fruit. Varieties include oranges, lemons, tangerines, grapefruits and limes. Proper watering is essential for citrus trees to produce the optimal fruit. Specifically, give it too much water and a tree will produce dry fruit; providing too little water could cause the fruit to drop early.
Set up a 3-inch deep well around the base of the three. The well should have a 2-foot radius around the entire base.
Fill the well entirely with water. For best results, begin watering early in the morning.
Allow the water to drain entirely into the soil.
Fill the well again.
Inspect the tree after four days to determine if the soil is ready for another deep watering. The best means of testing is to check that the soil is dry at 2 inches below ground level.
