Gypsum

Gysum is an all-natural NZ sourced product that works quickly to open up clay soils. It can be spread over areas of the garden and lawn that are ponding and it is ideal to apply to hard soil surfaces. Our Green-cal Gysum comes in a granular form that is easy to work with and faster-acting. Available in a 25kg bag.
