WHAT WE DO – Prevent Pests and Disease

We have international solutions for most of the common problems concerning pests and diseases in modern day agriculture/horticulture. see our archives section for the latest updates.

In 2017 we discovered that we have cured black spot in Roses with our HH-4 product. You only need to spread the end product 1 inch (25 mm) thick around the root zone of rose plants in the autumn, and then a second dressing before flowering and possibly a third dressing in the winter again if the problem persists.  NOTE There is no other cure for this condition with an organic product from any individual or any company.

The HH-2 system of growing is easier and a lot simpler than  ‘Bio Intensive farming’, and ‘the double digging method’ and the ‘Biodynamic’ system. It is more scientific than esoteric. The HH-2 horticultural/agricultural system shows how less machinery is needed and thus less fuel. Not only this, but our research shows over a 22 year period increased profits can also be easily achieved because the end product has such a high value. This is not a new science but rather is the result of the work of the great Sir Albert Howard MA., CIE., etc., combined with the other sciences that have been brought in by Richard Higgins – inventor and founder of this web site.

A comparative study by Rodale Institute is made between conventional systems and organic systems. But we can increase on these standard organic systems with the Howard-Higgins system which starts at the most basic level of agriculture/horticulture which is the micro organic level. We proliferate these organisms, namely fungi and bacteria, and introduce them into any soil type with the HH-2 system. Thus the soil will become instantly more fertile and will be able to support much higher densities of cropping. The economy is such that you do not need to apply the fertiliser, HH-4, every year once you have achieved the minimum standard of fertility.


We teach zero till and low till systems for horticulture and agriculture. The Good Gardeners have been practising no dig gardening for 55 years. This makes farming and gardening a whole lot easier. Together with two other sciences we now have a complete package to take sustainable farming and gardening into the 21st Century. No chemicals are needed in this system; organic or synthetic.


Indeed our surveys in Africa reveal that with this technology we can take children off the fields and put them back in school as far less work is required to grow increased harvests. You can help our work here by donating to the Good Gardeners charity.

The optimum fertiliser/soil conditioner, we have developed, known as HH-4 is complete in its quick and slow release properties. It is a plant medicine, a tree medicine and second to none in disease prevention. Anyone who purchases the HH-2 system will be able to produce this reliable and consistent end product HH-4 themselves.  John Innis Labs inspected HH-4 and stated that we have manufactured fertile top soil – something that takes Nature between 500 – 1,000 years to produce.

Consultants to the Industry

We are consultants for the regeneration of exhausted agricultural land and marginal land. Both these types of land can be brought into full production within one season with the HH-2 technology. With crops ranging from vines to  vegetables we are able to greatly increase crop production with pest and disease free capabilities.

By operating the HH-2 system correctly we can solve many of the problems in agriculture today.

By solving the problems of Pests and Diseases in the Farming World we can completely avoid the use and production of all types of chemicals, herbicides, pesticides and fungicides and all types of mining for the basic elements in agriculture, namely N P and K,  become completely unnecessary. All these and the CO2 emitting methods of refining them become unnecessary.


Like no other manufactured system

For small scale operators our HH-2 superfast Composter units are ideal – with No moving parts – and No electrical hook up. They are self convecting and self condensing and proliferate the right type of fungi and bacteria for the manufacture of a consistent and reliable fertiliser/soil conditioner in one. One pair of HH-2 can produce 8 tons of finished HH-4 per year in the temperate climate and 12 tons a year in the tropical and subtropical regions of the world. It is the design of HH-2 and the management process that is so effective. 


The HH-2 facilitates the right fungi and bacteria

WE CULTURE SPECIFIC FUNGI AND BACTERIA TO PROLIFERATE OVER A SPECIFIC TIME FRAME – This renders all manner of wastes into perfect worm food with a carbon to nitrogen ratio of 10:1 and in conjunction with biochar and Volcanic rock dust anyone who owns a TWIN SET of HH-2 can easily make this optimum fertiliser/soil conditioner known as HH-4.   The basis of the research for this work was Albert Howard, the great agricultural pioneer who observed that the fertile forest floor was at the outset in the region of a 10:1 carbon to nitrogen ratio. Thus this is the basis of  the research that has enabled Higgins to produce such an effective natural fertiliser and soil conditioner. Today it is being rolled out as the Howard-Higgins Horticultural System or more commonly known as the HH-2 Horticultural System.

This material HH-4 prevents pests and disease in all types of growing systems

Solve pests, disease and all your waste management problems at once with the HH-2 Horticultural System


The results are that all types of pests and disease will be reduced to an absolute minimum, meaning no slugs, snails or caterpillars, no aphids, black fly, green fly, white fly etc., eating your crops. This applies to all temperate, tropical and sub tropical zones. This has proven to be of great interest to the RHS’s head gardeners and assistants at Wisley and to the National Trust, Rothamsted, Niab, Wellsbourne Horticulrural Research International  (now owned by Warwick Univertiy) and to many Universities around the world.

A) Agriculture/Horticulture

With over 25 years of research,  we are able:

TO CONDITION ANY SOIL TYPE – WITHOUT ANY KIND OF SOIL ANALYSIS    to produce healthy and abundant crops in one season. This is a remarkable breakthrough in Agricultural technology.                                                                                                                         TESTED IN THE UK, FRANCE, INDIA AND AFRICA and HAITI

 “FRESH HUMUS”  (HH-4) HOLDS 20 TIMES ITS OWN WEIGHT IN WATER. (Oxford Real Farming Conference) Thus it is what is needed in modern day agriculture, what with climate change and increasing incidents of drought the natural wicking action (capilliary action) of the un dug soil fuels the crop with water in the very important earlty stages of development.         

PV smiling face

the happiness of free fertiliser


even the potato blight phytophthora infestans, which is an airborne blight, is done away with with the HH-2 technology.

For scaled operations we are suppliers of the HHI wheel hoe. By operating this simple tool weeding becomes a hundred times faster than by hoeing by hand hoeing.

please see our products page 

By purchasing the HH-2 system you will embark on a journey of agricultural adventure and without any previous agricultural training or PhD etc., you will be able to produce abundant produce for yourself and the community around you. Being guaranteed for 25 years the system will progressively produce free food. Also the system can be used to process waste into HH-4 which can be sold at a premium price equating to the system paying for itself in five months.


B) Health

Your soil will become continually micro-organically active and crops grown in this soil will contain fully synthesised protein rendering the crops unattractive to pests and disease. The health giving properties of food grown in this way is vastly increased as it contains much more minerals, vitamins and proteins and with many more times the anti oxidants than conventionally grown food.

Crop yields are increased and the attributes of disease resistance are passed on to the consumer; forming a stronger immune system for both animal and man.

We exemplify our work for schools, colleges and Universities to expound these principles into farming today. Also for NGO’s and their training staff, such as CRS., OXFAM, UNICEF, WORLD VISION, SAVE THE CHILDREN and NORGESVEL, etc., who may wish to take this work to the rest of the world.

The land at our Well End Micro-farm has not previously been ploughed for 45 years and and no expense of heavy mechanical subsoil treatment. We have employed deep rooting plants to crack the subsoil pan. Food grown in this way with the Zero Till/Low Till methods is much higher in minerals, vitamins and proteins and is ten times higher in anti-oxidants. And is therefore considered the fastest/safest route to Preventative Medicine (Howard).

This is the original science of Sir Albert Howard. Now reformulated for modern day use, passing all the Envirnomental Health regulations and guidelines against pollution from the Environment Agency.

with the conclusive research of both Sustainable Agriculture London and The Good Gardeners charity, the Director, Richard Higgins has moved this work into international status and is now appealing for help to take this work to the needy peoples of the world.

Please see our appeals on the web site  charity
Surface water control/drainage is essential for times of heavy rainfall, thus many plants can keep growing, unhindered, in all weather conditions.

All types of modern sustainable agricultural practises will benefit from the principles that we teach. These are missing in mainstream agriculture today the world over.  They will play a large part in food security and disease prevention in crops and animals in the future.

 If you wish to support our cause please donate to GGI stating what area of our work you would like to support. It is of the utmost importance that this science coming from the work of the great Sir Albert Howard CIE., MA., etc.,  who is now considered the Grandfather of organic farming, becomes available to the general public and the world-wide farming community.
