Learning Download: How to Grow Marigolds
Marigolds are popular, long-lasting and brilliantly colored flowers. Marigolds are commonly grown as annuals, but some varieties are perennials.
Before Planting: Begin Marigolds inside eight weeks before the last frost and place in a warm area. Once seedlings appear, remove the plastic and move to a sunny location.
Planting: Once seedlings have true sets of leaves and after the last frost has passed, transplant outside in a sunny location in a garden bed or container.
Watering: If planted in the ground, only water the Marigolds if dry weather persists for more than two weeks. Water Marigolds daily if they are growing in a container.
Fertilizer: Feed Marigolds with a slow-release 11-40-6 granular fertilizer. Be careful not to overfeed the Marigolds, as too much fertilizer will increase leaf production and decrease bloom production.
Days to Maturity: Marigolds take around 45-50 days to flower.
Harvesting: Harvest Marigolds for cut flowers in the early morning when the blooms are just beginning to open. Set the freshly cut stems in a vase with warm water.
Tips: Encourage more growth by deadheading the spent blooms.
