Difficulty: Moderately Easy
Things You’ll Need:
- Marigold seedlings or seeds
- <br>A flower garden or planting area
Step1
Don't plant your marigolds until the last frost is over. Many people find it easier to plant them from seedlings. Plants should be 12 to 24 inches apart, and you should pinch off old flowers to encourage more flowers and growth.
Step2
Marigolds control a host of pests like aphids, nematodes, cabbage loopers, Mexican bean beetles and cabbageworms. Plant the flowers near tomatoes, roses and potatoes. Many gardeners don't plant marigolds in their vegetable garden, but instead they grow them as a cover crop and then plow them under to control nematodes in vegetable beds.
Step3
Don't plant your marigolds near beans, or any member of the cabbage family, like Brussels sprouts or cabbage varieties.
Step4
Marigolds like full sun and average soil. Allow some of the flower heads to remain on the plant in the fall so they will self-sow in the spring.
