Ruby Red Grapefruit Tree

The Ruby Red Grapefruit Tree is a classic citrus variety known for its large, juicy fruit, attractive pink-to-red flesh, and pleasantly sweet-tart grapefruit flavor. The fruit is excellent for fresh eating, breakfast, juicing, fruit salads, and homemade citrus recipes.

Ruby Red grapefruit typically has fewer seeds than older white grapefruit varieties such as Duncan. The fruit develops yellow skin that may show a rosy-red blush as it matures. Its colorful flesh, refreshing juice, and traditional grapefruit flavor make it a popular addition to a backyard citrus collection.

The tree has glossy evergreen foliage, fragrant white spring flowers, and attractive fruit that ripens during the cooler months. Plant Ruby Red in full sun and well-drained soil. Because grapefruit is less cold-hardy than Satsuma mandarins and most sweet oranges, this variety requires a protected planting location and dependable freeze protection in North Florida.

North Florida Growing Note

Ruby Red grapefruit can be grown in North Florida, but it requires more winter protection than Satsuma mandarins, kumquats, and many sweet oranges.

Plant the tree in a sunny, well-drained location protected from strong north winds. The south or southeast side of a home or other structure may provide additional warmth during cold weather. Avoid low areas where cold air settles.

Because Ruby Red fruit normally ripens during winter and spring, freezing temperatures may damage the fruit before it reaches its best flavor and color. Protect young trees during freezes and provide additional protection for fruit-bearing trees when prolonged freezing temperatures are expected.
