How to Plant and Care for Marigolds
Step 1: Choose the Right Location
Marigolds thrive in full sun, so choose a spot that gets at least 6–8 hours of sunlight per day. They prefer well-draining soil but are adaptable to different soil types.
Step 2: Start from Seeds or Transplants
- Seeds: Plant seeds directly in the soil after the last frost. Sow them about 1/4 inch deep and keep the soil moist until they germinate.
- Transplants: Purchase marigold seedlings from a nursery for a faster start.
Step 3: Spacing
Space marigolds 8–18 inches apart, depending on the variety. Give them enough room to grow without overcrowding your vegetable plants.
Step 4: Watering and Fertilizing
Marigolds are drought-tolerant but benefit from regular watering, especially during dry spells. Fertilize sparingly, as too much fertilizer can lead to excessive foliage growth at the expense of flowers.
Step 5: Deadhead for Continuous Blooms
Remove spent flowers to encourage new blooms and keep the plants looking tidy.
Additional Tips for Success
- Plant marigolds as a border around your vegetable garden to create a pest-repelling barrier.
- Rotate marigolds annually to maximize their nematode-fighting effects.
- Combine with other companion plants, like basil or nasturtiums, for added pest control and biodiversity.
