Citrus paradisi Ruby Grapefruit has medium-sized seedless fruit, a smooth thin peel, and dark red flesh that offers excellent quality. A grapefruit tree is an easy-care and long-lived backyard tree that is highly valued for its productivity. A mature grapefruit tree can produce over 90 kilos of juicy, sweet-tart, crimson fruit, and with the Ruby variety, the fruit becomes even sweeter as it remains on the tree. To ensure the best growth and fruit set, grapefruit trees require full sun, and a planting location that receives at least eight hours of direct sunlight per day is ideal. With its productivity, delicious fruit, and easy care, a grapefruit tree is a great choice for any backyard. Grafted Ruby Grapefruit trees typically grow to 0.9m to 1.3m.
