This is probably an ignorant question, but something I've never really paid attention to.
I planted some dinky individual seedlings in my community garden plot in early summer 2015. We are talking about six inches tall, not much to them.
I paid attention to the weed control the remainder of the summer, not really to whether or not the plants were growing/multiplying.
This spring I have at least a few that have multiplied to five or six fans, one seedling multiplied to a small clump of about a dozen fans.
Did this all happen last year and I didn't see it, or does the plant do it's "stuff" underground, and shoot up the additional fans in spring?
Thanks for your wisdom/experience
