Probably ok to compost.

We have very recently (April) moved some rhubarb plants that originated from my FIL's family homestead many years ago, from Denver CO to SC. I desperately want to keep these alive, mostly for my husband. Any advice? Our ground is hard as a rock in most spots and has a lot of clay, so figured I need to keep them in pots. How big of a pot do I need, should I be sure to put them on the side of the house where there's mostly only morning sun, in order to continue the "family line", should I try and gather seeds from the plant for the following year? Thanks!

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

Please note the question was about QLD, not USA..(Sept is spring here) I'm going to give it a go about now 'ish' and hope it enjoys winter in Hervey Bay.

What's eating big holes into my rhubarb leaves, and can I safely use insecticides and still eat the stalks? Ulla

Look for some grubs or caterpillars and research some sprays on the internet. Read the label of the insecticide. Pick the caterpillars off and kill them.

We live in Christchurch. When is the best time of the year to split a rhubarb plant so I can give some to a friend
