Last autumn I dug up all my canna bulb/rhizomes and stored them in the
garage because I read that this would help get them started more
quickly this year than leaving them in the ground. Now they're just
starting to put out some green shoots. Should I plant them out or
will I get better results if I wait till the shoots are a few inches
long? Until then should I keep them in the dark or bring them into the
light? And should they be kept dry or sprayed with water? Any advice
would be appreciated.
