Growing Geraniums in Zone 8B

Garden geraniums (Pelargoniums) are some of the longest-blooming annuals available — and unlike most annuals, you can overwinter them indoors for years.

Zone 8B enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Start from seed 12-16 weeks before last frost for first-year blooms
• Deadhead spent flower clusters to prevent seed development and extend bloom
• Overwinter by bringing pots inside before frost; keep barely moist
• Take 4-inch stem cuttings in late summer to propagate for next year
• Scented-leaf varieties (lemon, rose, nutmeg) are especially aromatic

Companion Planting

Good companions: roses, marigolds, petunias

Avoid planting near: Overwatering — most common cause of decline

Harvest Timeline

Ornamental; harvest scented leaves anytime for culinary or aromatic use
