Planting & Care Instructions

Where to Plant

  • Sunlight: Give your grapefruit tree at least 8 hours of direct sunlight daily for the sweetest fruit and best growth. If you are growing it indoors or on a patio, choose the sunniest spot possible, supplementing with grow lights if needed during winter.
  • Soil: These trees crave well-draining, slightly acidic soil that never stays soggy. If your ground is heavy clay or overly sandy, amend it with organic compost to improve texture and drainage, or simply opt for a container with high-quality potting mix.

Watering Requirements

During the first year, water deeply once or twice a week to help the root system get established, ensuring the top few inches of soil dry out slightly between waterings. Once mature, the tree becomes more drought-tolerant, but inconsistent watering can lead to fruit drop or dry, pithy grapefruits.

Pruning Tips

Pruning is best done in late winter or early spring before new growth takes off, focusing on removing any dead, damaged, or crossing branches to open up the canopy for better airflow and light penetration. Since citrus doesn't require heavy pruning for fruit production, think of it as a light cleanup to maintain shape and health rather than a major cutback.

Fertilizer Needs

Feed your tree with a specialized citrus fertilizer three times a year: once in early spring, again in early summer, and finally in late summer. Avoid fertilizing after late summer, as this can push tender new growth that will be damaged by incoming cold weather.

#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.
