My Cannas are not growing at all. Been in the pot for about two months now - wonder if they will be a no show.I had planted one with about 4" green leaves and they have not grown after that at all. I think I can see the sides of the leaves turning a little brown - not sure though. I do water them once a week.
Do you have them in full sun? Mine were a little slow until the weather consistently stayed in the upper 70's during the day.
It may be that your soil temperature is still a bit cool, Tina. I don't think Cannas start to grow vigorously until the ground temps reach about 55 to 65 degrees.
