Dahlias container size?

[hididdlyho]

This will be my first year attempting to grow dahlia tubers in containers. I've just received 10 tubers of a patio mix. It doesn't specify the varieties, but says they are compact and will grow to around 60cm tall. What size container would you go for? I know they need plenty of space, so I'm guessing I'd be better off giving each tuber it's own pot? I know I'm a bit early to start growing them, but I don't think I have enough big pots, so will need to get myself sorted with them and also more compost!

I’ve grown some last year in a 30cm pot. Definitely need a pot each. They didnt do that well so I’m going to try for bigger pots this year. However that could have been the slugs! I also put some copper tape around the rim which seemed to help.

Thanks. I was looking at some 30l 30cm pots and 35l 40cm pots, so I'll go with the bigger size and hopefully they'll be ok. I'm trialling some copper tape around my pansy and primrose pots as they got decimated by slugs last year, if it works I'll get some more in for the Dahlias.

I had some in 40cm and 50cm pots and both did really well! I did use anti slug tape around the pots and a copper ring in the pots - the slugs decimated most of the ones in the ground but the pots were safe.

Definitely the bigger the better!
