I did read that digging stimulates it that is why I just pluck the tops now. Hopefully I will eventually starve the mothers. Also I am trying to stop the spore production, so I am fastidious about getting rid of every bit I can find every day during the growing season. Mine does grow in wet compacted clay. Removing all the thick mulch the previous owners put down did help to slow it down. It will be interesting to see how things turn out as the soil becomes more ammended
