French marigold
Tagetes patula
Marigolds deter nematodes and other soil pests that might affect Ageratum conyzoides.
common morning-glory
Ipomoea purpurea
Morning Glory competes for resources such as sunlight, water, and nutrients, potentially suppressing the growth of Ageratum conyzoides.
Aphids
Aphids suck sap from the plant, causing distorted growth, yellowing leaves, and honeydew secretion, which can lead to sooty mold.
Spider mites
Spider mites cause stippling on leaves, webbing, and eventual leaf drop. They thrive in hot, dry conditions.
Steps:
- Collect seeds from mature flower heads.
- Sow seeds directly into well-draining soil in spring after the last frost.
- Lightly cover the seeds with soil.
- Keep the soil consistently moist until germination.
- Thin seedlings as needed to provide adequate spacing.
