When should you stop forcing rhubarb? We have had ours for a long time - not sure exactly how long, as I did not plant it, but it must be at least ten years. I put big tubs over two of my four plants in March - I would have done this sooner, but I have not been out much because it has been so cold. However, there really is a difference between them and the other two. They have grown as high as the tubs which are about one and a half feet in height. I have raised them a bit with bricks. Should I now remove the tubs? There is a photo of the plants which I took last year in My Photos.

I don't grow rhubarb, but my understanding is that you get 1 crop of forced rhubarb, which can be started in december, as soon as you have this crop, just leave to grow naturally, but it wont crop very well next year,Derek.
