At the permaculture course we attended at the Durban Botanic Gardens, we learnt about the benefits a little plant called comfrey can bring to your garden. Planted as a green manure, it fixes potassium in the soil. The leaves can also be made into a liquid fertilizer or ‘green tea’ by soaking in a bucket of water for two days.
Needless to say, we went out and got a couple of plants. And they are growing really well. We have also made our first batch of ‘tea’ and will let you know if the garden likes it.
