I have been given some Canna tubers packed in multi-purpose, they are the smaller variety of Canna which grow to a couple of foot. What size pot should I use and what is the best growing medium ? Thanks- Geoff
I've grown them in the garden, and they were perfectly happy there, but you'd have to dig them up for the winter, or cover them with masses of mulch. They're not as fussy as you might think.
Probably a ten inch pot minimum, I would say Geoff. Use a good potting compost, the type for containers, I would add some osmocote or similar fertiliser, they like plenty of feed.
I have just read elsewhere, that they need to be in a reasonably large pot as the roots can expand so much in the season they can fill and break the pot. Don't use your favorite pot. :D :D :D
If you do decide to grow then in the ground geoff, dont plant them straight out into the garden, get them started with a bit of heat in the greenhouse, in pots first, then plant them out when its normal time for bedding plants in your area. That way they flower much earlier. :D
