I've got some rhubarb seedlings which I hope to plant out in containers. Does anyone have much experience with this? Any particular tips? I know rhubarb's meant to be a heavy feeder so I'm wondering particularly how to keep it happy in that regard. I've also heard it's a good companion to brassicas so I'm thinking of having it share a big tub with some kale (it's autumn here so the time is right).
Any other tips/opinions?
