Autumn is a good time to divide established rhubarb to propagate new identical plants for other parts of your garden or to share with neighbours.

 

It is also good practice to divide rhubarb every five years or so to stop them getting overcrowded and to keep them vibrant.

Divide the crown into sections using a spade. Each section should keep a bit of the root. Compost any decayed parts. Replant as soon as possible. If you plant more than one crown you should space plants about a metre apart. You can plant rhubarb crowns throughout the winter until March if you want to.

Rhubarb can also be sown from seed in spring, but division is the more common way to propagate rhubarb.

Rhubarb is a vegetable that is very easy to grow and harvest and crops for over ten years. It is happy in any kind of soil and hardy to the weather, but likes full sun.

It is best to leave newly planted rhubarb for 2 years before harvesting from it so that it can fully establish itself. Rhubarb is ripe in the spring and summer, but you should wait to harvest until the stalks are at least 10 inches long. And it is a good idea to slow your harvesting in July so that the plant can recoup its energy to get through the winter. 

By the way, rhubarb stalks are the only edible part of the plant. The leaves are poisonous.
