I haven't been able to buy Rhubarb Crowns in Armadale 6112. W.A. You can only buy Punnets.

Hi we live in Port Elizabeth and recently started growing a rhubarb plant in a pot. It has being doing fine although some critter has been eating on the leave. I came home yesterday and it looked like it had started wilting so I gave it some water,thus morning it looks like it is dying there are some new leaves at the bottom should I be cutting back the old growth?

I don't grow rhubarb but if the leaves are dead then cut them back.

Work out your climate zone then go to Rhubarb and set your climate, then check when to plant.
