How to make Comfrey Fertiliser

Comfrey brings bees into the garden and makes an excellent companion plant. 

Comfrey is a good source of nitrogen, potassium and phosphorus. The leaves can be used to a make a rich liquid fertiliser, particularly suited to potatoes and tomatoes.

To make Comfrey Fertiliser you will need:

  • comfrey leaves
  • a 10 litre bucket
  • water
  • a large stone or brick

Half fill the bucket with comfrey leaves. Place the stone on top of the leaves to weigh then down then fill the bucket with water. Leave the bucket in the warm, dry, sheltered place to let the fertiliser "stew" for about a month.

After a month strain the liquid and bottle. Label the bottle. The rotted leaves that remain can be used as a side dressing in the garden or added to the compost heap.

To use: dilute the comfrey liquid before using. For every cup of comfrey add two cups of water. The diluted mix can be used to water or as foliar feed for established plants. For young plants dilute the comfrey liquid 3:1.

NOTE: Comfrey leaves are quite prickly and can irritate skin so gloves are a good idea.
