Water Wise Gardens

Watheroo Bentonite is a vital component of a water-wise garden. This natural, unmodified clay is an effective soil conditioner that will improve your soil and is safe for aquatic systems, plants, animals and micro-organisms.

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.

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.

Treatment of Grey Water

Treatment of grey water to reduce fats and soaps

Greywater systems divert water from your bathroom and laundry for use in garden irrigation.

Bentonite Clay is perfect in the Treatment of grey water to reduce fats and soaps. Greywater systems divert water from your bathroom and laundry for use in garden irrigation.

Greywater can be defined as any domestic wastewater produced, excluding sewage. Laundry and shower water is what most people understand as grey water.

The main difference between greywater and sewage (or blackwater) is the organic loading. Sewage has a much larger organic loading compared to greywater.

Some people also categorise kitchen wastewater as blackwater because it has quite a high organic loading relative to other sources of wastewater such as bath water.

With proper treatment household greywater can be put to good use rather than wasted down the drain. These uses include water for laundry and toilet flushing, and also irrigation of plants.

Treated greywater can be used to irrigate both food and non food producing plants. The nutrients in the greywater (such as phosphorus and nitrogen) provide an excellent food source for these plants.

Bentonite clay is used as a weighting agent in water high in color and low in turbidity and mineral content.

The bentonite joins with the small floc, making the floc heavier and thus making it settle more quickly.
