My rhubarb plant is in its first year. I have planted in a potatoe grow bag, the rhubarb is doing very well but due to the weight is bowing over. I know I can harvest a few stalks, can the stalks be eaten in the first year. As the plant has done very well I am planning on putting it into the ground.

Rhubarb can be ready at anytime that the stalks reach at least 10 inches long. Another thing to consider is that you must leave enough vegetation to keep the plant alive, as this is how they produce their energy.
