Growing Rhubarb

I have a rhubarb plant that has grown lots of very large stalks with huge leaves. The stalks are red at the base but quite green for most of their length. How do I know when they are ready to harvest?

Rhubarb is ready to use whenever you feel it is big enough, it does not ripen as other crops.

Rhubarb seems to come in several varieties, almost all green stemmed to deep red. I have grown both types and as long as the stems are of a decent size they taste much the same when cooked. Delicious ! Just don't eat it too often, as rhubarb is very high in Oxalic Acid and can be toxic in large doses.

You can safely eat as much rhubarb stalks as you like, just don't eat the leaves, that is the part of the plant that is toxic but they are safe to compost
