Some good hints on re-using potting soil which can save money. Note, some care need to be taken in renovating old potting soil. Potting soils contain living organisms (including bacteria, fungi, and other microbes such as Legionella pneumophila Legionnaires' disease - Symptoms and causes) some of which can be harmful to human health. It is recommended that gloves and a facemask be worn when working with potting mixes, and by minimising dust by keeping the potting mix damp.
