How do you destroy wild onions?
I understand wild onions are ramps and there is a market for such. Look into it.
Hi Ermogene, here are a few things you could try - https://www.gardeningknowhow.com/plant-problems/weeds/killing-wild-onions.htm
I believe the best way to handle it is to dig them up.
These are designed to breakaway if you try to pull them up, leaving you with a handful of gree tops and the bulblet stays in the ground with the roots.
The best way is to dig them up, being careful to not shake off the dirt & you also do not want to compost them.
