Have your used tea bags, re-soak them and use them to start seeds off. When the seed has germinated, pop the whole thing into a pot of compost.

Take thin branches of Willow, the thickness of a pencil, strip the leaves off and cut the stems into one inch pieces. Soak them in water for a week and strain.
