I’m new here and new to growing Morning Glories. This has been my first time growing them. I planted a few different types in the spring. Some have had lots of beautiful blooms. One type I planted was a light lavender. It has grown beautiful vines but I’ve yet to have even one bloom. Don’t know what’s up with that.
My question is some of my vines are getting really scraggly looking. Is it time to cut them back? I live in northeast Florida.
