Monty Don goes No Dig

Monty Don, the Chairman of the Soil Association goes NO DIG!

In this article he has proclaimed that the best thing you can do is to spread a layer of compost over the land twice a year before planting. (we are so glad we sent him a sample) This is the No Dig system from the Good Gardeners. We sent him 40 Kg’s of HH-4 and he has tried it out. But somehow he is calling his page DIG FOR VICTORY?

The Good Gardeners research has reduced the effort to Spread HH-4 compost over the ground 1″ deep over the winter period and you need only do it once a year. We call it DON’T DIG FOR VICTORY! and if you do this you won’t get the slugs, snails or caterpillars either, so it really is DON’T DIG FOR VICTORY.


The health of the population is of paramount importance being affected by the quality of food produced, not only here but all over the world. Mineral, vitamin and protein content of the soil must be improved to improve the health of the population. The Good Gardeners are consultants to agriculture with scale up and we also teach in schools and colleges…… To become really sustainable we have to look at agriculture – from the roots up.

Link to a United States video on failing nutrition in that country 

….Everything in this talk, in America, is covered by the Good Gardeners technology. Although a little  on the heavy side..We feel that “Farmacy” is the way forward, as mineral supplements etc., are not assimilated in the body as well as food is.  The old adage springs to mind….. ‘let food be thy medicine ……….  Please also see our other web site http://www.suaglon.co.uk/


For 60 years the Good Gardeners have been advocating that real healthy food will give you a real healthy life. Founded in 1962. This web site and Sustainable Agriculture London (www.suaglon.co.uk) explain how this works.

Supermarket Promotions – now on HOLD

From our national work promoting our localised waste management programme to educate children how to manage their own college or school waste and sell the countries most effective fertiliser and pesticide made from it. We are having very good response.

In Cornwall we met two School Governors who want the HH-2 in their Schools

In Christchurch we met the Head Teacher of two Schools who is interested in having the education programme in her two Schools.

They all agreed that the learning of how to grow food is important and that good nutrition is the root of good mental and physical health.

This project has a local collection service to source waste from a variety of locations, including restaurants, shops and community kitchens and horse stables. The waste will all go back to the Manor where there are two sets of HH-2. There with the help of the students it will be made into compost for the farm in conjunction with their own waste from their restaurant and community kitchens. The finished product can be sold back to the visitors through their shop.

UK Schools – Improve immunity in children to protect against virus infection

Post on BBC NEWS on 17th November, 2018.

Due to cut backs in funding for schools, and some schools will be dropping hot school dinners altogether, all schools will be reducing the quantity and quality of their school meals  This means a drop in nutritional content for all schools. Therefore our National programme to educate children in the art of recycling to generate fertiliser that is full of minerals, vitamins and proteins is vitally important. The produce grown can go to the School kitchens or the children can take the mineral rich vegetables home for their Parents to cook.

Good Gardeners International have for 60 years been dedicated to improving the nutritional content of UK food which should be made available to everyone. Not least in Mental Health Departments of the NHS where this would not only be good therapeutic engagement for the patients but the best food their kitchens could use.

We know from our research and the research of the Institute of Brain Chemistry (IBCHN) that the nutritional content of food has three main effects on the population. Professor Crawford, the chairman has, personally visited our farm with his team and  fully supports the nutritional improvement growing methods of the Good Gardeners which are unique and have been developed over 25 years.

1. it affects from the prenatal stage of development the cognisant potential of all children
2. it affects the natural immunity in all people
3. it affects the mental and physical health of all people.


We have systems installed around the country that recycle the organic fraction of household waste and turn it into a revolutionary optimum nutritional fertiliser, HH-4, that prevents all kinds of pests and diseases in farming and growing.  We aim to fill the gap in University education in this field and teach this unique Science for the benefit of all.  Our HH-2 installations we train and demonstrate how to replenish soils that are deprived of OM (organic matter, in the right condition) This material HH-4 applied to the soil surface without ploughing or digging is a revolutionary approach to replenishing soils ‘and should be taught in every College and University’ Dr. Rosemarin, Research Director of the Swedish Environmental Institute.

The farm for sale listed above will be an ideal opportunity to train more local people in the art of replenishing soils without necessarily using high tech equipment used in modern farming.  Please donate for this UK project with the button above..   We also have appeals listed which require specific funding. Please write to us  info@ggi.org.uk   See the APPELAS tab and state which appeal you are donating to.


Statement from the Mother and Child Foundation

“If a child does not get the proper nutrition, even at the prenatal stage, it will not develop to its full capacity.”

Also 11 million children are threatened  with pneumonia this year due to a lack of nutrition in their diet which lowers their immunity. This will not happen with the Good Gardeners food growing programmes, similarly protection from the Corona Virus etc., will be increased with our type of food production.


STOP PRESS – BBC world Service 13th October, 2019

UNICEF have announced that it is now one third of the worlds children are malnourished resulting in malnutrition or obesity and that the world’s food system is failing them.

STOP PRESS – BBC world news 17th January 2019

International experts have announced that 11 million lives could be saved a year if we halve the amount of meat we eat and double the amount of fruit and veg.

Preventing malnutrition

For children who survive it, malnutrition has lifelong consequences, affecting their performance in school and future prospects. This has an impact on entire populations, contributing to a cycle of poverty. That’s why we’re doing everything we can to work with communities and governments to prevent malnutrition and break that vicious cycle.   (UNICEF, 2019)

“Our HH-2 technology offers a very cost effective method of producing nutrient dense food. Anyone who consumes food grown in this way will not suffer from malnutrition and will generate optimum immunity without taking supplements”   Director, Good Gardeners International.



Three Problems in many countries of the developing world

Centre, Richard Higgins, Director Good Gardeners International

Nutrition  –  Hygiene  –  Deforestation

Many children go hungry at home and in school in Africa. Often there is a lack of the supply of leafy green vegetables essential to a healthy diet. This is one of the main causes of malnutrition.

Poor sanitation systems are often the cause of pollution of water courses that are used for drinking water and irrigation water.

Exhausted and overworked soils are the result of over cropping with no soil replenishment and from deforestation. Where trees are burnt either for charcoal or to ashes the result is an unprotected soil that will quickly lose its nutrients by evaporation and when the rain comes  be subject to erosion. With the HH-2 system of soil remediation there is no need for a fallow period in the farming system and all soil types will be rejuvenated in one season.


All these problems contribute to problems of malnutrition, disease and loss of livelihood

One Solution

seed can be thrown down and just raked into the soil. The Hertfordshire Demo Farm

The HH-2 Horticultural System of waste management and DRY sanitation as taught by Good Gardeners International works ideally in association with Agroecology. If new land is required for food production then agroforestry design can be employed. The Good Gardeners offer this service.

When water runoff is a threat to soil erosion, planning and surface water management needs to be implemented. The Good Gardeners offer this service.

Once this is planned out, very often lines of productive trees can be planted and maintained with row cropping below. The two crops enhance one another.

Or the HH-2 equipment can be simply flown out from our Norwich factory and we go out and train chosen staff to operate it and they can start growing Super Healthy food for the people right away. This will prevent malnutrition which is the first stage of starvation.

The HH-2 Horticultural System does not involve digging over the ground or ploughing. This loses moisture and carbon especially at the critical times when they are most needed. By not digging the soil far more nutrition is transferred into the plants than in conventional systems.

There are thousands of acres of brush that are just burnt off every year in Africa. Instead of burning off brush it can be harvested green as a nitrogen source for input to the HH-2 with other wastes collected from households, schools, market places, food processing plants etc., all for use in the HH-2 system. The HH-3 DRY toilet system is designed for Africa and developing countries. These two components work in conjunction with one another and the output is processed into a rich nitrogenous fertiliser which is the key to regenerating exhausted soils. Moisture is kept in soil and new and existing carbon is introduced and protected. In India, many years ago, the Good Gardeners team set up an HH-2 and HH-3 system which was successfully managed by teenagers.

Anyone can learn how to make the end product HH-4 with the HH-2 equipment in conjunction with organic wastes that are just found lying around the world over. You can make HH-4 with just general farm/garden waste or with human effluent as a further nitrogenous input the choice is yours. All surplus HH-4 from your growing operation can be sold and will prove to be a good income generator.

So fertile

The land  becomes very fertile with the HH-2 Horticultural System of soil management and the crops produced keep for far longer due to their mineral content.  The health giving properties of crops grown this way are greatly increased as they all contain larger amounts of minerals, vitamins and proteins. The HH-2 system can also be used solely as a DRY sanitation processor; again the Choice is yours.


Thus any school, village or community can learn this simple, yet scientific,  technique. How to protect their drinking water from pollution and how to grow their own fruit and vegetables with a much higher standard of nutrition than conventionally grown food. (This science is Supported by the IBCHN.,…..read on)

Safe Drinking Water

Replacement of pit latrines with the HH-3, DRY toilet system, is always a first consideration when our teams arrives in any location. None of the problems, or costs associated with waterborne sewage, occur with the HH-3 DRY system. Even Cholera and Malaria are prevented because there are no pools or ponds holding any water or effluent where mosquitoes and rodents are encouraged to breed. It is an age old tradition in Africa to collect such wastes and re-introduce them into agriculture when they are fully processed (recycling). These diseases become such a great threat through poor sanitation and poor agricultural  management.

Environmental Health

With our equipment all environmental and health regulations meet the modern day requirements of the United Kingdom. Therefore the improved health and safety of all inhabitants employing the system will be a quickly noticeable feature. WASH clusters around the world can take advantage of our system and benefit any community in the same way by employing ‘The HH-2 productive sanitation system.’

Success Success Success

So effective is this concept of fertility making that the need for digging over or ploughing of the soil becomes completely unnecessary thus saving time, money and often child labour.  Our system employs unique fungi and bacteria that are generated in the system that process the wastes and subsequently attract and generate the myriad of microbial and larger life forms that thrive in fully fertile soil. The health of the plants that grow upon such soil are full of nutrients, trace elements and minerals,vitamins and proteins which are essential for the full and proper development of all those who are fortunate enough to consume food grown in this way. On fertile, weed free ground, seeds can be just thrown down and just raked in (pictured above) and will flourish – as demonstrated on the Good Gardeners demonstration farm in Hertfordshire, England.

Proof of Success

Today the soils of the world are becoming increasingly devoid of these essential organisms and elements and therefore produce foods of inferior quality which are prone to attack by pests and disease. Indeed our soil science is simple to understand. If the plants are being destroyed by pests and disease there is a sever lack of soil fertility. Likewise if there are no prevalent pests or diseases in your crops (without the used of chemical treatments) then you have achieved a good state of soil fertility.

Nutritional Development

By keeping the soil structure in tact, by not turning over the soil and feeding the soil with our soil improvement technique more nutrients become available to the plants  (mycorrhiza science). The nutritional quality of the food increases and hence the capacity for instance for proper child development both mentally and physically is thus realised. This work is supported by the research group   The Institute for Brain Chemistry and Human Nutrition, London and The Mother and Child Foundation. With Good Gardeners International you can help imbibe this science to the indigenous peoples of the world and help them learn a most important skill – how to protect their water sources from pollution, how to produce their own food crops which will be free from pests and disease and how to boost their intelligence and immune systems.

“There are enough resources to feed the planet if only the resources are  properly managed.” 

Richard Higgins, Good Gardeners Director

Food Economy

The HH-2 Waste Management and Horticultural System is an income generator and the quality of the produce will bear its weight in village and town markets. Market gardens near cities can also take advantage and supply the cities with the same quality and keeping power of fruits and vegetables the rural farmers will achieve. This will show the value and help preserve any indigenous culture.  The diet of all such inhabitants with access to food grown this way will automatically imbibe preventative medicine. (also see our web site www.suaglon.co.uk)

The system was so successful in the past, as employed by Sir Albert Howard – the originator of this science, that many communities’ health was documented and it was found that medical bills were vastly reduced and peoples life expectancy was significantly increased.


So why a charity and not just a business?

Put simply, we can do things that conventional businesses can’t. We take the time to travel to remote schools and rural communities, look at how they dispose of their wastes, and how we can easily close pit latrines and other waterborne systems, saving them water and disposal costs by installing HH-2  in conjunction with our DRY toilet system HH-3. This alone will be of huge long term benefit as governments and contractors are finding it increasingly difficult to service communities with cost effective disposal in wet systems such as the Vietnamese twin pit system and pit latrines in the time required – which often leads to overflowing pit latrines and septic systems that produce pollution rather than a useful fertiliser.

We can install the HH-2 Waste Management and Horticultural System as the basis for a growing programme in order that any school, village or community can supply and teach the sustainable concept of growing their own food while improving their economy and health at the same time. This system cleans up all kinds of organic wastes that are often found lying in heaps and rubbish piles that breed flies, rats and dogs.

To install a complete system with a full education programme also costs money. But it should be seen as a long term investment, not a cost. The benefits and knowledge transfer for schools and the above mentioned communities and their children will go on for ever.

We need help to get this investment to the people that need the most help – the Children of the future. Please donate with the purple button above.


 The HH-2 equipment  with its vermin proof  and insulated flat pack construction  generate the right fungi and bacteria enabling anyone who is trained to use it to produce abundant food on even so called marginal or un-usable land, because it re-introduces the specific fungi and bacteria back into the soil which enables the land to digest whatever organic mulches are placed upon it. This builds the soil rather than depleting it and the results get better year after year rather than worse year by year which is the result of farming with chemicals and ploughing.

So all shortfall in food production can be met with this simple but most effective tool.


Richard, Higgins, pictured right at the 3rd African Congress for Water and Sanitation in Kigali, Rwanda.

Richard Higgins, the CEO and director of Good Gardeners, lectures and demonstrates this system with tutorials through Colleges and Universities in the UK and lectures and installs systems in Africa.    He says the world can take up this science that preserves all animal and insect species by nature of its complexity and produce food for people at the same time. As soon as we get funding for our listed appeals (see appeals above) regional governments can then roll out the system across countries.

Over cultivation of the soil, the continued use of chemical pesticides, herbicides and fertilisers, is leading to a tsunami of unsolved pest and disease problems. Conventional farming, with chemicals and ploughing, destroys microbial life in the soil and leads to the loss of moisture and valuable carbon. For over  twenty five years the HH-2 System has demonstrated to reverse these soil conditions and also reduce all types of agricultural pests and diseases to an absolute minimum. Therefore it is of extreme importance that indigenous peoples, all over the world, can be trained in the management of such a system.

This was practised by the ancient Chinese thousands of years ago where the science was discovered. There need be no starvation in the world. It is growing cities that present the greatest problems for food security. It has been proven time and time again that you don’t need to be a farmer to operate this system. With the training that we offer… anyone can become a food producer; supply their own food and supply food for villages and cities as the Chinese have done for thousands of years. This is what is needed to alleviate world hunger.


70% of Africa and 70% of India are rural poor (Unicef)

Especially important for these peoples is this simple and easy to use HH-2 system which brings huge health benefits to the population. It automatically renders all wastes pathogen free in a 30 day period. This offers large opportunities for employment and as an income generator for micro scale local business. Supplying  cities with high quality fruit and vegetables which have much longer keeping power is also an essential part of our strategy.  (The keeping power of vegetables is dependant upon their mineral content. study by DEFRA., UK., 2007). We are now harvesting root crops, on our demonstration farm, that have been in the ground for up to 12 months since planting. This, in the UK, is food security for the ‘hungry gap’ early in the year. Also the storing of food crops in the ground means they are absolutely fresh when they are needed. This is a factor in ‘what is healthy food.’


Due to the proven science of ‘heat – destroying pathogens’ in containerised units, the HH-3 and HH-2 units offer a Cholera proof sanitation system.

Good Gardeners International’s mission is to pioneer this revolutionary technology across the world.

“What you are doing is in a sense revolutionary, but at the same time traditional”   Professor Michael Crawford, Chairman, Institute for Brain Chemistry and Human Nutrition. 

Bringing HH-2 to Africa and the World

Good Gardeners CEO explains the system to the charity ‘Slum Dwellers International’

Good Gardeners has extensively trialled and tested the HH-2 system from the Haiti earthquake in 2010 to scale up trials in Kampala in 2012.

Richard Higgins opened a waste remediation site, under the banner New Directions Foundation, at the Haiti earthquake disaster which was visited and won the approval of leading expert Professor Reid of WEDC (Water and Engineering Development Committee) who was sent to make an appraisal of the sanitation disaster in Haiti at that time. The film of this can be viewed on the above link.

Now moving on from this time the HH-2 equipment has been developed and introduced, which brings the processing system fully up to date meeting all the modern day health and environmental regulations of the West.

Further projects are now underway in Africa but we urgently need donations to help bring our mission and dreams to a much greater reality. We have staff trained and ready to install these systems.

Every school we visited in the Kampala area, some as large as 1,500 pupils, were all eager to receive this technology and training but we need your help to make this a reality.
