Add a lot of sand, they thrive in it.

Thanks. I can add sand, sure...

Anything else to do? I'd love to get some more of these but hope the winter (or I) won't kill them.

:-/

If you're talking about the variety called 'Tropicanna', it is hardy. I'm not sure what you mean by "tropical canna", though.

All mine come back. I just cut 'em down after the frost hits and then mulch over them.

Dunno...that's what's on the tag...guess i'll just go for it and hope for the best. The good news is that I can actually dig in my soil this year!!

I have the tropicanna and live in Southwest TN. This will be the 3rd season and I never dig them up. I do however have a problem with leaf rollers which is very common with canna lilies. I am treating them right now.

Traciham - Thanks. Of course, now I've had to google
leaf rollers to see what the heck they are! lol.

Is this *really* common?
What happens if you just leave them alone? Do they just eat some leaves or do they take over and become an army??

One site said: "If you find the grub inside, flip it onto a surface nearby where a bird can get a snack."

Does that work?

If not, I would look to hand pick & burn OR spray with soap as my "green" methods of control. I admit I'm not very good at killing bugs.

Other preventative non-chemical ideas?

Thanks. Sure hope mine make it through the winter. I used to not like cannas but this yellow one is really happy.

thanks!

I haven't had any this year but they totally ruin my canna's when they hit.

Hey --

I was in a Lowes today that had these cannas. It turns out that it's just a variety name. They have 'Tropical White', 'Tropical Pink', 'Tropical Yellow'. I read the tag, and these are just yer basic cannas. Same hardiness as any other cannas. So enjoy!

Oh, but if we get a really hard winter, be prepared to mulch em in good!

Andi, there are different ways to get rid of them, my way may not be well liked but I couldn't take it anymore and it seems to be working. I use liquid seven. I sprayed them, cut mine to the ground and then used some once they started growing back to make sure I got rid of all of them. They are beautiful plants and very easy to grow.

Cool. Thanks, everyone. I've planted and will keep an eye out for the bugs. So far, so good.
