A friend gave me a healthy looking bunch of rhubarb with leaves intact. I have heard that it is not good to eat the stems if they have had frost on them as the toxin is forced down the stalk from the leaf, is this true? Thank you

Can l grow rhubarb in a pot ? If so what is the best way to go about it?

I have had good success growing rhubarb in wicker bed pots (they are like a big self watering pot). I kept 2 plants in regular pots and they barely survived, but my plants in the wicker pots thrived. Google wicker pots if you haven't heard of them and there is plenty of good info on how to make them

Not recommended for pots. I tried over the years in Adelaide and had the most success in the ground.

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

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.
