More info

EM, Effective Microorganisms is a combination of useful regenerated micro-organisms that exist freely in nature and are not manipulated in any way.

EM-1 is used in over 120 countries to accelerate the soil building process, promote beneficial microbial communities, and decrease incidence of disease in all soil types. EM-1 produces high levels of polysaccharides and other beneficial enzymes and organic acids that help build stable aggregate and soil structure, reducing soil erosion and run-off resulting in soils that are better able to absorb and retain moisture, as well as cycle nutrients. EM-1 efficiently breaks down organic matter into stable humus, a key component to aggregate formation, by reducing oxidative forces that primarily rob the soil of C and N in the form of methane and ammonium gases. The result is a greater amount of organic matter being converted to humus, aiding in aggregate formation.

How to use:
EM1 Garden can be used as it is without any further preparation, although adding equal parts of molasses or raw sugar to the solution of EM Garden and water will enhance activity by providing a food source for the Microbes in their new home - your garden.

  • Dilute EM1 Garden with water, from 1/100 to 1/1000 dilutions
  • Soil and Plant Drench: Add 10ml EM1 to a 10 litre watering can, thoroughly wet soil and plants (apply to 10m2 of garden)
  • Foliar application for maintaining plant health: dilute EM1 Garden at 1/100 with water,  spray weekly during important growth stages and during stress periods
  • Apply EM1 Garden regularly to your compost for odour control and to enhance compost activity

Eco criteria

Eco Product selection criteria

When we source our products, we try to find as many environmental benefits as possible. We source eco products that do not cause any unnecessary harm to our environment.
This particular product matches the following critera (click on each to see other products matching the same):

All of our eco criteria explained

Made from recycled materials or is recyclable

Recycling has many benefits like saving energy, conserving raw materials, reducing the amount of stuff that goes to landfills and it's also saving you money. 2.5 Million Tons of waste go to landfills each year (8kg per person/week) 3/4 could be saved by re-using, recycling and composting. Re-duce, Re-use, Re-cycle!

Contain no toxins or harmful ingredients

Many people suffer from allergies, asthma and other sensitivities because of products that contain toxins or otherwise harmful ingredients. Most of these products are used inside the house eg. for cleaning, as body care products, as a detergent and so on. We try to source products that are mostly natural and do not cause any harm to you or your environment.

Be compostable or biodegradable

What is the difference? Compostable materials provide the earth with nutrients once it has completely broken down. Biodegradable materials refer to the ability of breaking down and return to nature. Buying products that are compostable and/or biodegradable will help to reduce the amount of waste that goes to landfills.

Fairly traded or Fairtrade certified

At the beginning of most production chains are the workers and farmers (producers). Sadly they do not always get a fair share of the benefits of the trade. You as a consumer can now make a conscious decision about buying fairtrade or fairly traded products and putting this right.

Reduce the dependence on oil

Many household items are made of plastic. Because plastic doesn't react chemically with most other substances, it doesn't break down or decay. Therefore, plastic poses a significant environmental problem as it hangs around in the environment for a very long time. We stock many products that use little or no plastic in order to reduce our dependence on oil.

Cruelty free

The testing on animals for cosmetic and consumer products needs to stop. Whether you decide to buy only vegan products, or just start incorporating more cruelty-free products into your life, it's definitely worth to go animal friendly. The products we source are cruelty-free and do not harm or kill animals in their making.
