Pinching zinnias - subsequent growth process
I know there have been posts on this before, but I am looking for a bit more detail. I grew a bunch of "Cut and Come Again" zinnias from seed, hoping to get earlier blooms (and prolong the bloom season) since I live on the edge of zones 5a and 4b. Maybe that was unnecessary and any that I plant directly outside (once we actually finally get consistently warm temps!) will surpass the indoor seedlings in growth.
In anyway, I am looking to keep several of these plants lower and bushier, for pots rather than for cutting. I pinched some of them after they got a fourth set of leaves. What can I expect to see now, growth-wise? I just keep reading that this will make them "bushy." How, exactly, will they grow? Will the stem, which so far has been tall and non-branching, with pairs of leave growing in at alternating orientations, now branch? So far nothing is happening.
