Canna's - can i??

There was a thread here Armandii on Cannas http://gardenerscorner.co.uk/forum/cannas-10-things-t1888.html

I kow very little about Cannas - other than having read a book. However I believe that they can get pretty big and so think that the bigger the pot the better. I grew three plants from seed last year in a 35 litre pot. But hopefully this year they will be bigger.

 

I think if you can find a warm spot they actually do better planted out in the border.
If growing in pots its difficult to say how big would be needed as cannas cone in all sizes.
In general I'd go for at least a 10in pot per plant.
But I'usually start in a smaller pot say 6in for now and move them up once well rooted.
They like a good spongy compost that holds water.


Lots of water and feed once established:thumb:

At the end of summer I dry them out and cut off the foliage, in that order, then keep frost free but cool.

 

Out of interest it would be nice to see which varieties you have bought Armandii

 

Hi Armandii,
I don't know much about canna's, the reason being they are a favourite food of slugs and snails, which in my garden is the reason for not growing them.

Good luck!

 

A nice collection there Armandii. I only know Wyoming and King humbert.
Just keep an eye open for virus.

I had quite a nice collection a few years ago and lost the lot to virus, I had not heard of it at the time so I'm only getting back into canna growing very tentatively these days.
