Vermiculite is one of three key components of square foot gardening. Vermiculite is a mineral that expands and contracts in response to changes in temperatures more easily than other minerals. The constant expansion and contraction, as well as moisture retention for longer periods of time is what makes vermiculite an invaluable tool for successful square foot Gardening.
Vermiculite is lightweight and easy to handle when mixing with soil, fertilizers, compost materials and other components used in square foot gardening. Vermiculite moisture / nutrient release characteristics eliminates worry of over- or under-watering or fertilizing and allows square foot gardens to flourish.
