- Tea bags and ground coffee are a great source of compost.
- Keep all your used tea bags and old ground coffee in a box until you have enough.
- Break all the tea bags up and mix them into the compost around your plants.
- Egg shells are also very good for the plants.
- Borage leaves are a great homemade fertiliser. For the best results, mix a handful with water, leave to soak for at least 48 hours and pour it around the plants.
