Worm castings contain enzymes, beneficial bacteria, and humus.They contain no salt and cannot burn plants like animal manures. Worm castings, in a sense, moderate a plant's uptake of heavy metals as well as excess acidity or alkalinity from the soil. They provide an organic water- soluble source of fertiliser that is rich in nitrogen, phosphorus, and potassium. In fact, the amount of potash is nearly 7x that found in regular fertilisers! This translates into dynamic root growth and plant structure. It is also a great source of calcium, magnesium, and other micro-nutrients that are key to overall vitality. Adding them to your vegetable garden will boost your production!
We add castings to our seedling mix to encourage healthy root, and strong plant growth.
