I have been growing broccoli for a couple of months now. The first head I cut off was not as firm as the ones you get in the grocery store, but it was still decent. I thought maybe I didn't let it go long enough, so the second head I let go a while longer. The second head was pretty loose and fluffy. I even let it go so long that I found one bud opening to a flower. What can I do to make the heads firmer?
