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

Wed Jun 3 18:29:26 PDT 2015

Now is a great time to pull rosettes from along rocky creek shores.  I spent
an hour last spring doing that and had very few plants to pull there this
year.  By now those plants would have been huge.  This is good June work to
do.  Pull plants in lush areas before the first week in May before the
vegetation gets thick and the deer tick nymphs form. 

I always try to pull the root.  When the plants are tender or the soil is
hard, I grab the plants at their base.  If the plant breaks off, I brush
away the soil and find the white root or stem base.  Normally I don't need
pliers to pull them, but they might be handy to have.

Is there some actual research on this topic? It seems to be pretty important
in getting a grasp (sorry for the pun) on this.

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.
