homemade garden plant fertilizer

You could try planting some Comfrey seeds in your garden and gather ing the leaves to infuse into water. When they have completely rotted down and you are left with a green SMELLY liquid add about one cup full to 10 litres of water and feed your plants. If you don't want to grow comfrey gather some nettles in the
Summer and do the same thing with them, however you will only get the infusion later in the Summer rather than earlier. If you live near the sea gather some seaweed, wash it and infuse that into water, cut it up first as it is much thicker than the land loving plants.
