#ProPlantTips For Care
Citrus need full sun to have the most flowers and therefore the largest crop of fruit! Indoor growers may need to grow lights to extend their sunlight hours.
Grapefruit also requires very well-draining soil on the acidic side. Any medium with excellent drainage is best, preferring to dry out slightly between waterings.
Citrus prefers low moisture environments. Sitting in water will lead to root rot, so be sure your site doesn't pool after a heavy rain, and your containers and planters have excellent drainage holes.
Protecting Container Citrus From Cold
Although it's famous for growing in warmer regions, it can also thrive in colder areas as long as the tree is brought indoors prior to the first frost of winter.
If you're growing these tropical trees in the ground in the lowest of their favored growing zones, they need to be planted in a sheltered spot to avoid the worst of the chill. If a spot like that is unavailable, then you are better off planting in a large, deep container.
In borderline growing zones, begin slowly acclimating your tree indoors or into a protected location, eventually moving your tree inside in bright indirect sun for the winter if the temperatures in your area ever dip below that 40°F range. In spring, reverse this process and begin acclimating your tree to again be back out in the full sun all summer. This reduces stress and leaf drop.
Fertilize with an acid-loving plant fertilizer such as Dr. Earth Acid Lovers Organic and Natural Premium Concentrate Fertilizer 3-4 times a year.
Keep your investment protected from cold drafts and sudden temperature or environmental changes, as this will result in leaf drop and stress.
