I have never grown it although my mother grew it in the 1960's. I think it grew a bit wild. Read all the notes here about climate to grow in, soil type, good draining soil, not heavy wet soil. Research on the net

My rhubarb is about ten years old. The plant has never been higher than 10 cm's with one or two leaves the size of a normal hand. Every year I leave it thinking next year it will grow better. Unfortunately it does not happen. What can be my problem?

Rhubarb grows for about 10 years. If you have had poor crops from it I would think you haven't looked after it very well. Plants are like us, they need feed - fertilising and watering. Maybe time to plant some fresh new ones. Prepare the soil well before planting and in a new position.

Is rhubarb best planted in garden or pot

The difference between pot and outdoor garden is how much time do you have to look after a pot. Watering and fertilising more often.

I was wondering what sort of rhubarb plant to buy as I live in Adelaide . Did have one in a pot but I think the heat got to it.

There green stem ones and red stem ones. Look at seed selling company on the internet. I use Boondie Seeds.

https://www.tuigarden.co.nz/how-to-guide/rhubarb-growing-guide/ Here is a website about growing it. Do some research about growing it. Read a lot of different websites about what is required to grow it.

Last night I read wilt is a condition in the soil near impossible to treat. Suggestion don't grow rhubarb in wet damp soil, have good draining soil. It could be an iron deficient. If you have wilt pull the plants out and destroy. Don't grow that crop in that garden bed for 4 years. Use crop rotation. I may have more info tomorrow about using Dettol.

Try a cap full of Dettol in 4.5l of water and put on the soil around the plants.See how that goes.
