Container Grapefruit Tree Care: Fertilizing, Overwintering, and Repotting

Fertilizer Schedule

Apply a balanced 10-10-10 fertilizer in spring and summer. Because the tree is in a 2'×2' pot, it will likely need repotting into a larger container next spring.

Winter Strategies for Ohio

You have two options:

• Dormant storage: Keep the tree barely moist in a dark, cool (above freezing) basement—exactly what you did last year.
• Active growth: Place it before a sunny south-facing window and supplement with fluorescent lights hung a few inches above the canopy.

Why It Bounced Back

Citrus are resilient. Leaf drop from frost and dry storage is a survival response; with warmth, light, and water, they often regrow vigorously.
