Use comfrey leaves

to make a high potassium fertiliser for tomatoes, potatoes, cucumbers, and peppers.

• Fill a bucket with comfrey leaves.

• Top up with water and cover.

• Leave to decompose for 3-5 weeks, occasionally stirring (hold your nose).

• Strain the sludge – put it on your compost heap. To use, dilute half and half with water.
