Overview

Marigolds are annual flowers that bring a wealth of gold, copper, and brass blooms to your summer flower garden. Easy to grow, marigolds are an excellent choice for cheerful, extra-large blooms, especially in containers or beds!

Conditions

Marigolds prefer moderately-fertile, well-draining soil rich in organic matter. For optimal blooms and large plants, provide full sun (6+ hours of direct sunlight per day).

Planting

Marigolds are most commonly started indoors and transplanted into the garden. Use our grow calendar tool to find specific planting dates for your region! Seeds germinate quickly in 4-7 days.

Plant seeds indoors in starter pots or trays 4-6 weeks before your desired transplant date. Plant ¼" deep and keep the soil surface moist until emergence. Transition outside (harden) for 7 days before outdoor transplant. Space 8-12" apart for most varieties. 

In warmer climates, marigold seeds can be directly planted outdoors in the garden. When the soil is warm, plant 6 seeds per foot, 1/4" deep. Cover lightly but firmly. Keep the surface from drying out until emergence. Thin to 8-12" apart after the first true leaves appear.

Care

Watering should be done by soaking soil thoroughly, then allowing soil to dry somewhat between waterings. Once plants are established, begin pinching off stems to encourage bushier growth. Deadheading (removing old flowers) is not required, but can encourage new flowers to grow in their place. There is no need to fertilize marigolds during growth - too much nitrogen will cause plants to grow lush greenery but few flowers. 

Harvest

Cut flower stems when blooms are fully open but still have tight centers. Hang upside down to dry for long-lasting dried flower arrangements.
