How to make comfrey fertiliser

Comfrey fertiliser's great. Comfrey has really long roots, so it unlocks nutrients from deep in the soil. Turn it into fertiliser to let your other plants benefit from those nutrients too. The liquid can be used as a general plant food, but is particularly good for tomatoes. Here's how.

1. Find some comfrey. It looks like this:

Comfrey

2. Fill a plastic milk bottle with comfrey leaves (use a stick to poke them down to the bottom so you can fit as many in as possible).

3. Fill up with water and seal the lid.
4. Leave for 3 to 5 weeks.
5. Dilute 1 part fertiliser to 20 parts water for use.
