Delicious Grapefruit on a Compact, Ornamental Tree
With its deep green leaves, fragrant white spring blossoms, and golden-orange fruit, the CELGEN Ray Ruby Grapefruit Tree is as beautiful as it is productive. This variety combines the sweetness of Ruby Red with a refreshing tartness, delivering grapefruits that are perfect for snacking, juicing, or adding to recipes.
Superior Growth with CELGEN Rootstock
Each Ray Ruby Grapefruit Tree is grafted on our own tissue culture–developed rootstock, produced in the CELGEN laboratory. This provides:

Uniform and vigorous growth

Resistance to soil-borne diseases and nematodes

Care Guide
1. Planting – Choose a sunny, well-drained location. For pots, use a container twice the size of the shipped pot with drainage holes.
2. Watering – Water weekly during the first year, more in hot/dry weather. Once established, water every 2 weeks when the top 2 inches of soil are dry.
3. Fertilizing – Use 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 danger has passed.
5. Pollination – Self-pollinating, but planting a second tree can increase yield. Indoor trees can be hand-pollinated with a fine paintbrush.
