Growing Citrus in Florida and the Gulf Coast: A Complete Guide

Citrus in the South: One of the Greatest Garden Rewards

Few things beat walking out to your yard and picking a ripe orange, grapefruit, or lemon directly off the tree. For gardeners in zones 9 through 11, that is not just possible but relatively straightforward with the right variety selection and basic care. This guide covers everything you need to know to grow productive citrus trees in Florida and along the Gulf Coast.

Best Citrus Varieties for Florida and the Gulf Coast

Satsuma mandarins are the best choice for gardeners in the upper South, zones 8b through 9a, where occasional freezes occur. Satsumas can handle brief temperatures into the upper teens and still recover. They produce sweet, easy-to-peel fruit that ripens in fall, typically October through December. Owari satsuma is the most widely grown variety in the South.

Navel oranges are the classic choice for Central and South Florida, producing sweet seedless fruit from November through January. Washington Navel is the most popular variety. Hamlin is an excellent early-season orange that is highly productive and performs well across a wide range of southern conditions.

Meyer lemons are beloved for their sweeter, less acidic flavor compared to standard lemons and grow well in zones 9 through 11. They are also slightly more cold-tolerant than true lemons and can be grown in large containers that can be moved indoors during cold snaps further north.

Grapefruit varieties including Ruby Red and Marsh White produce large, flavorful fruit and grow best in South and Central Florida where the long warm season fully develops their sweetness. Kumquats are among the most cold-tolerant citrus and produce abundantly even in zone 8b. The small oval fruits are eaten whole, skin and all.

Planting Citrus Trees in the South

Citrus needs full sun, at least 8 hours daily, and well-drained soil above all else. Root rot is the number one killer of citrus trees in the South and it is almost always caused by soil that holds too much water. Plant on the highest point of your yard or build up a planting mound to ensure good drainage. Dig a hole slightly shallower than the root ball so the graft union sits above the soil line.

Space standard citrus trees 15 to 20 feet apart to allow for mature canopy spread. Dwarf varieties can be planted 8 to 10 feet apart and work well in smaller yards or large containers.

Fertilizing and Watering Citrus

Citrus are heavy feeders. Use a specialized citrus fertilizer that includes magnesium, iron, and micronutrients in addition to the primary nutrients. Apply according to package directions starting in late winter and continuing through early fall. Do not fertilize in winter as this pushes tender growth that is vulnerable to cold damage.

Young trees need regular watering for the first two years. Once established, citrus trees are fairly drought-tolerant but fruit quality and quantity improve significantly with consistent moisture during fruit development in fall and winter.

Protecting Citrus from Cold

Even in South Florida, occasional cold snaps can damage or kill citrus. Young trees are especially vulnerable. Wrap trunks in frost cloth or old blankets when temperatures below 28 degrees are forecast. String incandescent lights in the canopy for added heat. Mature trees can often survive temperatures in the mid-20s for a few hours with some damage but survive.
