The Q&A Archives: Grapefruit Tree

Question: I have this grapefruit tree that I started from seed, it's about 20 years old, growing indoors. The tree is about 6 feet high but it has never produced a flower. Can you tell me what I can do to help it produce fruit?

Answer: First, congratulations on keeping a citrus tree growing for 20 years! It's possible, however, that your grapefruit will never flower and produce fruit, even though it appears healthy. If your tree were to flower, it would take 18 months for the grapefruits to mature! You might try taking your plant outdoors during the spring and summer months and then bringing it indoors during the fall and winter months so it can rest. You can let the soil dry out a little during the resting period. Then in the spring begin watering as usual and place the plant outdoors for the summer. This treatment will get your tree back into a more natural rhythm and may shock it into producing flowers. Good luck!
