Rhubarb like lots of manure, a good water supply and cool roots. If you can provide this in a large tub there is no reason why not

Hi live in Goulburn NSW which is best time to grow from seed and how to thank you

i would sow rhubarb seed in the spring when the weather starts to warm up. Seeds need to be lightly covered with soil and kept moist. Spring sowing will give the plants a chance to attain some size before the following winter. Seedlings can be very variable from green to red stalks and from thin to thick stalks. Discard the seedlings after the season that don't meet your requirements.

My rhubarb is mostly leaves. Huge leaves and very short stalks??anything I can do to change this?

Nearly all of the rhubarb available is grown from seed which means that growth can be variable. An excess of nitrogen can also cause excessive leaf growth as well so don't fertilise this winter and see if the stalks are bigger next season.

Cheap potting mix is fine. Just make sure to add some slow release fertilizer and compost in it. I don't waste my money on expensive rubbish that you can make yourself for half the price. As with all potting soils you must continue to feed it. The only difference between cheap and expensive potting soil is 6 months of a plant living in it then the expensive one has the same quality as the cheap one

My rhubarb has been in about a year and I'm dying to harvest!!! Is it too soon? The colour is good and quite thick.

If the plants are doing well and have a number of good sized stalks you could very carefully take a few. Push the stalk down towards the ground and give it a careful twist to separate it from the plant. Do this carefully as you don't want to damage the crown or pull it out of the ground. New roots will be subject to damage if you are not careful. Enjoy!

Thank you Giovanni. Done as you suggested and already cooked. Can see more shoots coming through. Yummy!!!!

I have just planted out two rhubarb plants in new veggie garden.......pretty good soil with small amount of clay. In about four weeks they have developed quickly into sturdy plants, good thick stems and huge leaves. As we are going into winter (Gippsland, Victoria) I want to cut all the stalks back to within a few cms of the roots thus allowing for new stems, hopefully ready to cook, in about three months. Good idea or not?
