Worm droppings that you buy ready-made can be immediately sprinkled on the soil or added to your plants.
Worm droppings from your own worm bin can be quite wet but do not have to ripen first like cow dung. It can be useful to let the wet worm droppings dry first so that you can scatter it more easily.
Wet worm droppings that have dried can become a hard ‘stick’ or lump. Crumble this or mash it finely. This also applies to worm droppings that you use outside.
