Bag - Gypsum - 15kg

Gypsum in a 15kg bag — natural agricultural gypsum in a 15kg bag — the standard clay breaker.

What it's used for

• Breaking up heavy clay in garden beds
• Improving drainage in soggy lawn patches
• Adding calcium without changing soil pH

How much you need

Spread at about 1kg per square metre — one bag treats roughly 15m².

Yard tip: Apply before mulching and water it in properly. Gypsum sitting dry on the surface does nothing.
