Canna is a very vigorous grower that does not require fertilizer in normal garden soil. The pot size is an issue mainly to keep the plant from falling over as it puts on more height. Al

I would defintely wait till you see good growth about the mulch, and then slowly remove it. I would not fertlize with anything till the plants are at least 12" into new growth. Then go to it! good luck to you Boca Joe

You can plant them anytime. I've started them indoors around December, and by late February or early March they go outside. I also get seedlings popping up all by themselves at any given time of the year. I have to go around and pick them from the flower beds. If you want them to grow fast, i would put them in the ground as soon as possible. They are EXTREMELY fast growers and you can get large plants within a month or two.

MonaRae, Canna's are tropical (sub-tropical) plants, and yes, you should wait till the danger of frost has passed before you plant them outside if you're planting potted ones. When I really want a showy mass of canna I start them indoors. Do that if you have the room do it. :) If you're just going to plant the bare tubers, you are probably be safe doing that the first of May. When is your last frost date? Cannas love heat and moisture, so make sure you keep them well watered. Have fun! Diann
