This natural, unmodified calcium bentonite is an effective soil conditioner that will improve your soil and is safe for aquatic systems, plants, animals and micro-organisms.

Bentonite Products WA source calcium bentonite from our own mines at Watheroo in Western Australia.

Watheroo Bentonite is a vital component of a water-wise garden:

  • improve water absorption on non-wetting, or water-repellent soils
  • increase water and fertiliser retention in sandy soils
  • improve the quality of soils for lawns, vegetable gardens, pot-plants and native gardens.
  • supply soluble plant nutrients, including calcium, magnesium and potassium.

Application rates:
New garden beds for vegetables, flowers, lawns, and native plants.

  • 3 - 5 kg per square metre (unimproved sandy soils will benefit from higher application rates)
  • add a high qualtiy matured compost as well (5-10 kg per square metre)
  • spread clay and compost onto surface of soil and mix into top 15-25 cm manually or using a rotary hoe.

Established gardens, trees, and lawns.

  • 1-2 kg per square metre: apply 500 g per square metre, 2–4 times over several weeks
  • add a high qualtiy matured compost, 2-5 kg per square metre.

Establishing new vegetable and flower beds, lawns, pot plants and soil mixes:

  • spread dry bentonite granules across the soil surface
  • apply compost or manure as desired
  • work the bentonite and compost through the root zone to a depth of 25 cm.

Establishing a native plant garden:

  • spread dry bentonite granules across the soil surface
  • work the bentonite and compost through the soil to a depth of 25 cm
  • apply mulch.

Existing gardens and flower beds (light application only):

  • apply dry bentonite to soil surface and work in well – either manually, or by watering in if there is a risk of damage to existing plant roots.
  • add manures, composts and fertilisers as required.

Existing pot plants, shrubs and trees (light application only):

  • to avoid disturbing roots, add 4 standard cups of clay to a 10-litre watering can (stir well) and apply to the soil
  • regular applications, rather than heavy single treatments, allow the clay to gradually incorporate into the soil.

Existing lawns (light application only):

  • spread dry bentonite over the lawn and water in thoroughly
  • regular light applications, rather than heavy single treatments, allow the clay to incorporate into the soil.

Precautions

  • Bentonite clay granules are very stable, however keep granules dry to ease handling and distribution.
  • Use dust-mask when spreading to avoid inhalation of fine dusts.
  • Spilt clay can be slippery and a hazard when wet.
