The Ruby Red Grapefruit Tree has shiny, green foliage that covers the tree from top to bottom and produces fragrant, white four-petal flowers. Ruby Red Grapefruits are round, baseball sized fruit with a pale lemon color tinged with pink blush. The flesh of the fruit is sweet, juicy and brightly red. This tree must be grown as a patio plant or indoors. It will not tolerate freezing temperatures. Move your grapefruit tree inside when temperatures drop below 40 degrees.
Exposure: Full sun. Plant the Ruby Red Grapefruit tree in full sun and well-drained soil. For about 2 months after planting, water your grapefruit tree deeply 2 times per week. Once this citrus tree is established, water deeply when the soil dries out. Citrus trees are drought tolerant and much prefer dry soil over wet soil. However, the Ruby Red Grapefruit tree, just like other citrus plants, love humidity so water over the leaves in dry climates for the best results.
Fertilize: Feed this citrus tree with a balanced slow release fertilizer in early spring and late summer. Citrus plants in pots lose nutrients much faster than citrus plants in the ground. Therefore, they should be fed more often. We recommend feeding potted citrus 3 to 4 times per year. Fertilize citrus in containers at the end of winter, early summer and again in fall for the ideal growth and performance.
Soil: Well drained.
