Growing Grapefruit from Seed Indoors in Atlanta

A seedling grapefruit can be a fun houseplant, but don’t expect bushels of fruit. Keep it compact and move it seasonally:

• Winter: 1-gallon pot, sunniest window or 2×40W fluorescents. Minimal water, no fertilizer.
• Spring (nights >50°F): Move outdoors to bright shade. Feed monthly with houseplant fertilizer.
• Pinch tips at 12 inches to maintain bushiness.
• Repot to 5-gallon as it grows.
• Fall (nights ~40°F): Bring back indoors. Decorate for holidays!

‘Meyer’ lemon, calamondin, and kumquat are more reliable for indoor/outdoor citrus.
