Thank you to Bill Redhead for this important reminder: now is the time to pull these plants from your yards. Bill also asks that you cover up when walking through tall weeds to protect yourself from ticks.
Garlic mustard (Alliaria petiolata) is a highly invasive, shade-tolerant biennial herb spreading rapidly across North American woodlands, displacing native plants by altering soil chemistry and outcompeting wildflowers. It is identified by heart-shaped, toothed leaves that smell like garlic when crushed and clusters of small, four-petaled white flowers in their second year.
Invasive Impact
- Rapid Spread: A single plant can produce over 60,000 seeds per square meter.
- Seed Viability: Seeds can remain dormant in the soil for up to 30 years.
- Ecosystem Damage: It releases chemicals through its roots that inhibit the growth of native fungi and other plants.
Control and Management
Disposal: Do not compost; burned or bagged plants are recommended because seeds can mature even after the plant is pulled
Removal: For small infestations, hand-pulling is effective, ensuring the root is removed.
Timing: Pull before the plant sets seed (before or during flowering).
So rewarding because it pulls out so easily! Timely message.
Great reminder Bill, I’ve pulled several of those nasty weeds. Two years ago my place was covered and I noticed the damage they were doing to the other vegetation around the weeds.
