Rhubarb

Rhubarb

Easy to grow.
Acquire part of a crown and get it covered in well rotted muck. Feed annually heavily. Remove flowering stems as it takes away the plants energy.

The flower

Needs to be removed as it takes energy from the plant for growing edible stems. The flowers are delicious apparently!

Snails on rhubarb leaves

Not normally an issue as the leaves are huge.
