~I bought two crowns last year from Farmyard Nursery Hywel ~Temperley Early? I think~ and they are in very large pots with lots of horse manure.They grew well last year~ hopefully they will come through the winter and I will be able to take some this year~

Rhubarb will grow in a position with plenty of sun, I would mix garden soil and compost together and put it in a Half Barrel and make sure you put in plenty of drainage in the bottom of the Barrel as they don't like to get water logged.
Give the plants plenty of water and fertiliser during the warmer months. Occasionally add some Blood & Bone.
In late winter divide clumps about every three years.
Potted Rhubarb needs more care than Rhubarb in the ground..
These pots can be connected to an automatic or manual drip watering system. I put 2 crownd in the ground last year One was called Pink Champagne which my dear old Dad when alive grow and the taste was Luvely, I also put a Strawberry Rhubarb in too but yet too find out what that one taste's like.

Thank you both

i had some in a large tomato pots for 3 yrs until i could get them into the grown.

Thank you. I have some very big tubs and I hope to grow them in those. They should be all right.

should be yes Hywell.
