Growing Rhubarb

View the Rhubarb page

17 Jul 21 David L. (South Africa - Summer rainfall climate)
I live in Howick KZN. I grow rhubarb in deep pots on the north side of our house (probably too hot) in a compost/soil mix regularly watered. Our area has heavy clay about 200mm below the surface, hence the reason for the pots. Our rhubarb grows many thin stalks (5/8mm dia.) quite slowly and many die before getting above 5mm dia.. The picked stalks are tasty if one has sufficient of them. The plants are about three years old and grown from a split off from a crown. Does rhubarb favour any particular soil PH? More or less water? Any particular soil mix? Require any special feeding? What is ideal soil depth? Your guidance would be appreciated. Thank you.

Try building your garden bed higher or use something to break up the clay - like gypsum or dolomite (I think). ph 5.5 - 6.5. Good soil depth of 12
