I have some gerberas and I looked online to see how to dead head them and I read that you are supposed to cut the stem at the height of the tallest leaf and then the flower should bloom again. Well I have done this, and it doesn't seem to want to grow back. Is there something else to do?
Also, how are you supposed to dead head geraniums? Do you take the little stem off, just the petals, or from below the little stems?
