Marigolds are more than just bright bursts of color in the garden—they’re natural pest repellents, pollinator magnets, and surprisingly easy to grow. If you want your marigolds to thrive this season, try these ten planting secrets that can make all the difference.
1. Choose the right variety. African marigolds grow tall with giant blooms, while French marigolds are compact and perfect for borders or containers. Select based on your space and style.
2. Start from seed indoors. For earlier blooms, sow seeds 4–6 weeks before the last frost. Transplant once the soil warms for stronger plants.
3. Prep healthy soil. Marigolds love well-draining soil enriched with compost. Avoid overly rich soil, which can lead to more foliage and fewer flowers.
4. Use companion planting. Place marigolds near tomatoes, peppers, or beans to discourage nematodes and aphids naturally.
5. Give them sunlight. Marigolds need at least six hours of sunlight daily. The more sun, the more continuous blooming you’ll enjoy.
6. Avoid overcrowding. Space African varieties 12–18 inches apart and French types 6–9 inches. Proper airflow keeps plants healthy.
7. Water wisely. Deep, infrequent watering is best. Let the soil dry slightly between sessions to prevent root rot.
8. Deadhead regularly. Removing faded blooms encourages the plant to keep producing fresh flowers well into the season.
9. Try natural mulch. Mulching retains moisture, suppresses weeds, and keeps roots cool during hot summer months.
10. Harvest seeds. At the end of the season, dry flower heads and save seeds. You’ll have free planting material ready for next year.
With these simple tips, your marigolds will reward you with weeks of vibrant color while helping your whole garden thrive. Whether you’re a beginner or seasoned gardener, these little secrets will make your marigold patch the star of the season.
