- Improves water absorption and retention
- Prevents leaching of manures, composts and fertilisers
- Contains calcium, magnesium and potassium
Application rates for new garden beds are 3-5 kg of bentonite per square metre along with manure or compost. This should be dug in to a depth of 15-25 cm. The rear of the bag contains full information on application rates in other areas of the garden.
