[MAIPC] The Garlic Monster - Third Year Adults and Beyond

[Margaret Chatham]

Or you could continue to pull the basal rosettes, but have a pair of pliers
in your pocket to extract the roots immediately if they break off. I still
like the idea of being able to fit a thousand pulled plants into a grocery
bag instead of having to lug a large garbage bag around.
