Grapefruit trees usually reach maturity after 5 years and can produce over 200 pounds of fruit. Grapefruit grows best in full sun. Direct sunlight is essential for fruit set. Choose a planting location that has at least eight hours of direct sunlight a day. Avoid planting near the north or east side of buildings or trees that could cast a shadow on the grapefruit tree. If freezing temperatures are the norm every few years, choose a location on the south side of a building for some potential protection. Choose a planting location that will accommodate the tree at maturity—grapefruit trees grow to 10–15 feet wide and 20-25 feet tall.
Grapefruit trees grow best in loose, well-drained soil. They do not tolerate slow-draining, heavy soil. Long periods in moist, clay and clay-like soil will quickly kill a grapefruit tree. The best soil for grapefruit trees is somewhat sandy in texture and with the ability to clump when moist.
Plan to water a newly planted tree every few days, slowly delivering about five gallons of water to the root zone. Keep up the regular watering for about two months, at which time the young tree should be established. Water during extended dry spells as needed. Mature grapefruit trees rarely need supplemental watering.
Hardy in Zones 9 and 10, grapefruit trees are sensitive to freezing temperatures. A freeze can eliminate fruit buds for the following season and kill entire branches or the tree itself. If a freeze is predicted, cover a young tree with a blanket or tarp, securing the edges of the cover to the ground. Mature trees are nearly impossible to protect from a freeze. A healthy grapefruit tree thrives with humidity at a minimum of 50 percent.
