I’m wanting to apply gypsum to my lawn. What quantity per square metre should I use? 

• Use Gypsum at a rate of 500g – 1kg per square metre of lawn.
• One 8kg bag will cover 8-16 square metres.
• One 25kg bag will cover 25-50 square metres.
• The application rates vary due to the type of soil the lawn is growing in.
• For heavy clay soils use it at the higher rate, for good soils use at the lower application rate.
• Water in well after application.
