Growing Marigolds in Zone 5A

Marigolds are the gardener’s best friend — they repel pests, attract pollinators, and brighten any bed.

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

Top Growing Tips

• French marigolds are best for pest control; African types are taller and showier
• Plant around tomatoes, peppers, and squash to deter pests
• Root secretions suppress nematodes — plant where you’ll grow tomatoes next year
• Deadhead spent flowers for continuous blooming
• Easy to direct sow or start indoors 6-8 weeks before last frost

Companion Planting

Good companions: tomatoes, peppers, squash, beans — almost everything!

Avoid planting near: none — marigolds are universal companions

Harvest Timeline

Flowering begins 50-60 days from seed; save seeds from dried flower heads
