Do you have heavy soils? A desire to insure non-compaction within your soil? Pumice is what you need!
Pumice is an ideal growing medium. It provides excellent aeration to the soil, it loosens heavy clay soil and retains moisture well. Being a type of volcanic or igneous rock, it's been formed from molten or partially molten material, so it won't break down, compact or rot, giving your roots the space they need. And it includes trace amounts of vital minerals such as: phosphorus, potassium, calcium, magnesium, sodium, copper, iron and manganese.
Just the addition of as little as 10% pumice in potting media and garden soils, you can improve your soil. The porous nature of pumice allows it to hold vital nutrients in the microscopic surface pores, which helps regulate fertilizer feedings. It can even be supercharged with nutrients before it is added to the growing medium. In addition, pumice is pH neutral.
It can be added to your worm compost unit as a great bedding additive - adding additional air space, prevents matting and helps to control moisture.
Coarse-grind pumice makes an excellent attractive mulch for flower and shrubbery beds. It does not break down, so doesn't need to be replenished.
