It says to remove the flowerstalk but no mention why there is a flowerstalk.. I was suprised today to find a stalk at least a meter high?? WHY....???

Rhubarb produces a flowerstalk and flowers so that it can produce seed. all plants need to propagate. Rhubarb can be grown from seed, but first the seed has to be produced!

Best you google about it. Flowering is part of the life cycle of plants.

Where do you buy the rhizomes from in Western Australia Perth area? I have tried before to grow but with no success so going to try containers. Thank you. Faye

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.
