Prune confusion...Tagetes lemmonii
I planted Mt. Lemmon marigold October 2009. It has bloomed through most of the winter and is still putting out blooms. I deadhead every several days.
I found this pruning advice online: "Prune lightly in spring to encourage bushier growth and more bloom but do not prune in summer."
As spring is winding down and summer is not far off, is now the time to prune? Somehow it seems a waste to prune while blooms are still coming but I don't want to miss the opportunity to prune. I've heard this plant can get out of hand.
Should I prune by about one-third now? Thanks.
