This is my first time planting cannas. I've been going through the forum to look for information, but I still have some questions. I have four red wine cannas that I would like to plant. Three will be going into the ground, one will go into a planter.
Since I am in a cooler area, I'm wondering if I should start the cannas inside and move them out after the last frost? If I begin them inside, do they need a heat mat and lights? These are bulbs (tubers?). I am assuming that they will bloom the first year.
I also read conflicting information about fertilizing them. Are they heavy feeders? Does too much fertilizer cause alot of leave, and few blooms?
