Growing Cilantro in Zone 5A

Cilantro is a fast-growing cool-season herb that bolts quickly in heat. Plan for succession planting.

Zone 5A has a moderate growing season. Most crops do well here with proper timing around frost dates.

Top Growing Tips

• Bolts to seed (coriander) in warm weather — plant in spring and fall
• Succession sow every 2-3 weeks for continuous harvest
• Slow-bolt varieties like ‘Calypso’ extend your harvest
• Let some plants go to seed — coriander is a great spice
• Self-seeds readily if you let it flower

Companion Planting

Good companions: beans, peas, tomatoes, spinach

Avoid planting near: fennel

Harvest Timeline

21-30 days for leaves; 90-100 days for coriander seed
