Choose citrus trees that thrive in your climate. Oranges, lemons, limes, and grapefruits are common. If space is restricted, choose dwarf or semi-dwarf cultivars.
Full sunlight benefits citrus trees. Place them in an area with 6–8 hours of direct sunlight. Make sure no surrounding buildings or trees shade them.
Citrus trees like well-drained, slightly acidic to neutral soil. Add compost or peat moss to thick or clay soil to increase drainage and fertility.
Maintain moist but not saturated soil. Water thoroughly, especially in hot, dry weather. Wetting the leaves can spread illness, so use a drip irrigation system or water at the tree base.
Spread organic mulch around the tree's base to conserve moisture, discourage weeds, and regulate soil temperature. Keep mulch several inches from the trunk to prevent rotting.
Use a balanced citrus fertilizer to feed your trees regularly. Fertilize in early spring and late summer per manufacturer's directions.
Trim your citrus trees to balance their shape, remove dead or diseased branches, and improve canopy ventilation. Pruning should occur in late winter or early spring before new growth.
Young citrus trees are frost-sensitive. Protect them from frost with frost blankets, heat lamps, or Christmas lights in cold weather.
Aphids, scale insects, and citrus leaf miners should be monitored. Insecticidal soap or horticultural oil should be used immediately.
