Background. Garlic mustard ( Alliaria petiolata) is an herbaceous member of the mustard family ( Brassicaceae) brought over by early European colonizers.

How does garlic mustard flower?
As an herbaceous biennial, it propagates solely through seed. In the spring of their second year, garlic mustard rosettes rapidly elongate their stems and produce a flowering head. Each plant will release many, sometimes thousands, of highly mobile seeds. Light enough to be carried by wind, they can also travel in water or by soil movement. The seeds also remain viable for long periods—over five years in optimal conditions.
What is the best mix for biennials?

Ecology
- According to the Indiana Native Plant Society, garlic mustard is considered one of the ten most destructive invasive species in Indiana today. Fortunately for us, we have options to rid ourselves of this pest of a plant.
Life cycle
- Garlic mustard has a biennial life cycle, meaning that it completes its life cycle over a two-year period. Seedlings germinate in the spring and form into basal rosettes -a low cluster of heart-shaped leaves by midsummer. Immature plants will overwinter as rosettes that stay green and continue to photosynthesize during periods when temperatures are above freezing giving them …
Reproduction
- All plants that survive the winter produce flowers in their second year and then die. An average plant produces 400-500 seeds that germinate readily in both well-lit and shaded environments. In the following spring, the garlic mustard will shoot straight up into a tall, slender flower with clusters of small white, four-petal flowers. Since the plant only flowers in the second year, the pl…
Prevention
- Eradicating garlic mustard is easy work, but takes time. Lots of time. Vigilance is key, as garlic mustard can sprout up even when you're sure that you've gotten rid of every last one. The ultimate goal in removing garlic mustard is to prevent seed development and spreading until the existing seed bank is depleted. Unluckily for us, this may take 2- 5 years in any confined area. Cutting th…
Preparation
- It's important to know when pulling garlic mustard you should always make sure that the taproot is completely removed or the plant will re-Garlic mustard its sprout. All cutting should be bagged, dried and then burned or buried deep into the ground. Contact your local landfill to see whether or not they will do this for you.
Management
- Controlled burns or herbicides may be needed in larger areas as way to lower labor costs. Both methods have potential drawbacks. Fire for instance can be ineffective if too cool or too hot. Fire that is too cool may not have an effect on the plant removal; instead it may just increase the presence of garlic mustard. Fire that is too hot can change the composition of the soils top layer…
Treatment
- The method you choose depends on the size of garlic mustard infestation you have, and the type of environment the plant has invaded. Regardless of method, eradication should always take place before seed development.
