Maintenance Level Guidelines
it is important that each leaf gets sprayed. First year plants can also be sprayed in the late fall, after frosts have knocked back all native plants. Garlic mustard plants will still be green and growing, and can be killed at this time without affecting native vegetation. Garlic mustard control is a multi-year project. Don't forget the seed bank. Just because this year's crop has been removed does not mean that your work is finished. Be prepared to come back next year, and the next, and the next, until "finally" the area is under control. Reseeding eradication areas If a heavy infestation is being dealt with, it is important to reseed the area with native plants after eradication. Collect seeds in the late summer or fall from nearby healthy woods, save these, and plant after the garlic mustard plants have been eliminated. Remember that most native plants have been wiped out by the garlic mustard infestation. Once the garlic mustard has been eradicated, native plants can become established again. If you have healthy woods, it will be difficult for garlic mustard to get started.
