I succumbed to the lure of growing my own rhubarb, and bought a young plant in August. I planted it in our tiny front garden(about 3 yards square), and it loves it there! It's about 18" from one of the corners. On the opposite wall to the rhubarb corner we have a young grape vine and a climbing rose. It seems that there is quite a lot of bare soil. I've read that rhubarb needs its own space, but how much space?
