Important reasons to choose organic!
  • Organic fertilisers are of benefit to the soil, not just the immediate crop.
  • Natural products based on kelp, rock minerals, fish and animal manures have a slow release.
  • Chemical fertilisers are highly soluble so may wash into the waterways causing toxic algal blooms.
  • The fast, lush growth caused by chemical fertilisers also attracts pests and fungi to the plants.

BD 500 Preparation
Aracaria Biodynamic Farm, located in Mullumbimby, New South Wales, are now making available to the home gardener their Biodynamic Preparation 500. This product is made from manure supplied by Aracaria's own lactating cows that has been buried in cow horns during the cooler months of the year. The pure 500 is then embedded in Aracaria's biodynamic Cow Pat Pit compost. The CPP contains the biodynamic preparations 502 – 507 as well as crushed egg shells and basalt dust. Preparation 500 enlivens soil by improving soil structure and microbiological activity and promotes humus formation and water holding capacity. You can divide the preparation into four equal parts and mix in 4 to 8 litres of water. Each part is enough for a seasonal application providing your home garden with a biodynamic feast for the full year or you can use the entire pack to cover 0.5-1 acre. Illustrated application instructions are included. Keep the 500 in its special packaging in a cool, dark, dry place.

Biochar Active - Soil Conditioner.
Better Earth Products' Biochar is an environmentally beneficial soil conditioner suitable for vegetables, herbs, trees, lawns, pot plants and ornamentals. This highly porous substance is formulated to improve soil structure, boost drought tolerance and reduce fertiliser requirements. It will improve soil quality and thereby enhance plant health and performance. This 100% Australian product is made from agricultural and timber residues by a rapid thermal carbonisation process, so rapid that the char is created in 90 seconds. This converts a portion of the organic matter into a stable form of porous carbon that is then inoculated with nutrients and beneficial soil microbes.

Biochar removes carbon from the natural carbon cycle and locks it into productive soils for potentially thousands of years. The open porous structure holds moisture and nutrients and creates habitat for microbiological life. It increases the cation exchange capacity (CEC) of the soil and is alkaline with a pH of 8 - 9, which will help reduce soil acidity.

By increasing your carbon held in the soil you will reduce high rain fall nutrient loss, sweeten acid soils, reduce long term fertiliser costs, improve soil moisture retention and contribute to sequestering carbon in the soil.
  • Improves soil structure and improves soil life
  • Reduces high rain fall nutrient loss
  • Sweetens acid soils
  • Improves raised garden bed performance
  • Long term reduced fertiliser costs
  • Less fertiliser, same yields
  • Improves soil moisture retention
  • Sequestered fixed carbon can last millennia
Nutrient Analysis:
Fixed Carbon: greater than 65%
Organic matter: 10 - 20%
Plant sourced minerals and nutrients: 8 - 25%
pH in CaCl2 solution: 8 - 9
Suggested application rates are a minimum rate only.
Existing Trees: Sprinkle 5 handfuls per square metre around drip line.
Planting Trees: Thoroughly mix 5 generous handfuls of Biochar Active into topsoil and water in.

Material Safety Data Sheet

Can I use Happy Roses on other plants?
Yes. Happy Roses can be used all over the garden, especially on plants with waxy leaves. On sensitive looking leaves do a plant test patch first.
Does Happy Roses kill aphids?
It is not designed to kill aphids, but it does act as an effective repellent. To kill insects, use Beat-A-Bug Naturally Based Insect Spray.
What is the best way to control black spot and other fungal diseases on my roses?
General good gardening practices are always beneficial. For instance, roses should be planted at a distance apart at which they do not touch each other; watering should never be done from above, as drops spread fungal disease; roses should get at least six hours of sunlight per day; they need a well fertilised soil with plenty of organic matter (sheep manure is particularly good) and they should receive frequent deep watering.
In addition to the above, Happy Roses should be applied regularly. Naturally occurring sulphur and seaweed extract in Happy Roses controls existing black spot while the general qualities of the product boost plant immunity against further attack. If at any stage black spot should re-occur, remove damaged foliage and discard or burn.

I just wanted to drop you a quick line to let you know how delighted I am with the Backyard Bloom (Ed. now called Organic Blooms) fertiliser. I have been using it fortnightly on my bean plants and am having a wonderful result. Before I used to use 'flower and fruit' products because I could never find an organic high potash liquid. I will be using it with all my flowers now as well as my tomatoes!

How do you decide which fertiliser to use?
For gardeners with large areas, planning new orchards or market gardening, a soil test is essential. It gives you a starting point to judge your soil's improvement over the years and identifies initial problems that have to be addressed. Without the information from a soil test, large sums of money can be wasted on inappropriate fertiliser applications or young trees lost due to nutrient deficiencies.
For home gardeners it is hard to go wrong just adding compost to the soil, with organic seaweed or fish fertiliser to help seedlings along. Organically certified fertilisers such as NTS Liquid Humus and Organic Link can safely be used in any gardening situation. Soils vary a great deal from region to region, in some areas of Australia soils are low in magnesium whereas SE Queensland is the reverse, often far too high in magnesium but low in calcium. As a general rule Australian soils are deficient in trace elements which is why a seaweed spray such as Natrakelp is a useful addition.
Checking with a local organic gardening organisation will give you the benefit of the members long experience and understanding of your area's climate and soils. See our links page for websites.
Why buy organically certified fertiliser?
English is a constantly evolving language and changing all the time. Many words have several meanings and 'organic' is one of these. 'Organic' meaning carbon-based is one meaning used as the opposite of inorganic. Grown without the use of chemical fertilisers and pesticides is simply another meaning, that has developed semantically since the early 1900's. This is obviously a valid meaning as the function of language is communication and this meaning is understood by millions of people world-wide.
Organically certified fertilisers are those where the original materials and the processes to manufacture them have been audited by an organic certifying organisation. This means that tests are done for heavy metal residues and chemical residues such as fungicides. To give an example, gypsum mined as rock could be available 'organically certified'; gypsum as a waste product from gyprock manufacture with residues including fungicides could not be 'organically certified'.
