Canna in containers
I'm trying to decide whether to grow my canna in large pots this year and wondering if anyone has done this. What results did you have? Did you use any type of plant food? I know they require lots of water, so did you come up with any type of watering system?
I usually pot them up around now so that they have some growth on them before I put them out in the garden, but thought that if I used a bigger pot I could just leave them in it for the season and move them around as desired.
I live in Ontario, Canada which is zone 5b for Canadians. Thanks for your help and advice.
