you really are better off putting them in a raised garden bed with mixed clean top soil, lots of compost, peat moss, blood meal, and a slow release fertilizer. Rhubarb get very large and can live for many years and their root systems can get quite large, keeping them in pots will restrict their growth and you will have to water more often and continually use fertilizer more often then them being in the ground.

I just ordered rhubarb crowns and plan on planting in a raised bed. My concern is that the roots will be harmed in my 6b zone winter given they are in a raised bed. What do you recommend?

I suggest you read some articles about growing them. The bigger the pot the better 18-24

Can I successfully grow Rhubarb in Miami if I plant it in a pot to keep it out of the direct sun in the summer? What variety would grow best?

In 10b zone it says here it won't grow. It is probably too hot.

Will rhubarb grow in my zone if I plant in a container and if so which kind should I plant?

Can grow rhubarb in a big pot? And which area in the garden can I place it? Thank you.

It grows fine in a big pot and is happy in semi-shared areas.

Is it too late to plant rhubarb from plants this year in my zone? The chart above says March. Or should I wait until next year? Thank you!

What about growing rhubarb in the San Jose CA area? I am in a warm, sunny, dry subtropical zone. The last rhubarb I planted was Victoria. It was pithy and green and bothered my stomach. I was going to try KangaRhu which supposedly is bred for warmer climes. I am a transplanted Midwesterner who misses my rhubarb. Has anyone had successful experience in my area? What type?
