Ruby Red Grapefruit Seeds 5+
Hand Harvested in 2012 from my grandmothers orchard, which has been growing Texas citrus for over 50 years.
FOR WARMER CLIMATES ONLY!
Grapefruit achieves its best quality under conditions of hot days and warm to hot nights, which results in higher sugars and lower acids than grapefruit produced in the cooler night temperatures common in Arizona and California. It grows well in both tropical and subtropical climates of the world, but it is a little less cold hardy than oranges.
Mature, healthy grapefruit trees that are well-hardened by previous cool to cold weather can probably tolerate temperatures in the mid-20's without leaf or twig damage, although ice will form in the fruit of grapefruit after about 3 to 5 hours at 27. Because severe freezes kill grapefruit trees in the Lower Rio Grande Valley, successful home grapefruit production will sooner or later require cold protection measures.
SOILS AND SITE SELECTION
Grapefruit trees on sour orange rootstock are well-adapted to deep, well-drained soils. Loamy soils are preferred while heavy clays and poorly-drained soils will result in poor growth and production as well as shorter life.
For maximum cold protection, grapefruit in the home landscape should be planted on the south or southeast side of the house. Distance from the house or other buildings and driveways or walkways should be at least 12 feet to allow adequate room for the tree to grow to its mature size. While large, overhanging shade trees will provide some cold protection, grapefruit grows and produces best in full sun.
