Wollastonite Lawn & Soil Mineral

Your lawn's biggest threats - grubs, disease, weak roots, and acidic soil - often trace back to the same problem: mineral deficiency.

Wollastonite is a naturally mined calcium silicate mineral that works below the surface to build a healthier lawn from the ground up. It delivers calcium to balance soil pH and silicon to strengthen grass cell walls, making your turf more resistant to grubs, fungal disease, drought, and heat stress. Unlike lime, it releases slowly and steadily - no sharp pH swings, just consistent improvement that lasts two to four years per application.

One of its standout benefits is natural grub control. The mineral's fine crystal structure physically deters grubs in the soil without chemicals, pesticides, or risk of runoff. It's straight from the ground - mined in eastern Ontario, completely natural, and safe for kids, pets, and the environment.

Apply in spring or fall at a rate of roughly 10 kg per 5,000 sq ft.
