Ruby Red Grapefruit Tree – Citrus × paradisi ‘Ruby Red’

Seedless, Sweet & Nutrient-Rich Grapefruit, Grown at Home

The CELGEN Ruby Red Grapefruit Tree is America’s favorite grapefruit for good reason — it offers sweet, seedless fruit that’s easy to peel and bursting with flavor. This variety produces abundantly during the winter months, so you can enjoy fresh citrus when other fruits are out of season.

Superior Growth with CELGEN Rootstock

Every Ruby Red Grapefruit Tree we offer is grafted on our own tissue culture–developed rootstock, produced in the CELGEN laboratory. This guarantees:

• Uniform and vigorous growth

• Resistance to soil-borne diseases and nematodes

• Long-lasting productivity and consistently high fruit quality

Perfect for Garden or Patio Growing

Ruby Red thrives in the ground in warm climates but can also be grown in large containers in cooler regions. Simply move it indoors during the cold months and place it near a sunny window to keep it productive year-round.

3. Fertilizing – Feed with a citrus-specific fertilizer from February to September every 4–6 weeks.

4. Pruning – Remove suckers and prune dead or damaged branches in early spring after frost risk has passed.

5. Pollination – Self-pollinating; indoor plants can be hand-pollinated with a small paintbrush.
