I have a row of pyracantha (Mohave) orange berries. I planted them last fall. I am trying to create a hedge. I planted them about 2ft apart. I have about 8 of them. They seem to be growing bushier at the top and not at the bottom. They look healthy. Still have berries. When do the flowers come? Do the berries turn into flowers? How can I get them to spread out on the bottom please?
