Our green home

Our green home is a series of essays printed in our local newspaper. It covers subjects as diverse as harvesting rainwater and sunshine to making compost heaps; and growing many different legumes for vegetable protein.

Starting on the green journey will be daunting but it is made one step at a time, beginning at where you are.

That could be a need for more vegetable protein from your food because you have had a scare in the family; you want to cut back on commercial red meat. Free-range methinks is quite different if you can get it.

Then you would want to start with growing green beans and peas; and learning how to make hummus.

Or perhaps you are getting repeated infections and want to know how to increase the antioxidant vitamins for your well-being; and making a natural probiotic in your own kitchen.

Could you create a little blue zone in your own home and garden where longevity, many years without the chronic diseases that today bedevil our lives, becomes central to your planning?

Not only the length but the quality of our remaining days on Mother Earth is obviously important. Vibrant, busy and strong with all one's marbles intact to the last breath is our motto.

"To stand with those who see the world differently from the majority is not easy. It requires a degree of courage and a willingness to follow our own individual path."

- Dr Tess Lawrie, MD

I am not a vegetarian myself but it lies in our family history, so growing lettuce and rocket is where we personally began; and herbs like parsley. My great-grandmother gave up meat after witnessing the slaughter of horses for food during the siege of Ladysmith.

Recycling the waste from our homes is something that all those who have a love and respect for the planet should be doing. Do you want a habitable, pristine place in the sun for your offspring?

In short start where you are, rather than the first blog you read.

Our green home

Our green home covers the blogs published in the media over the last five years. We will set it up in categories. Taking good care of ourselves and our possessions is the theme tune.

End of winter chores like cleaning out gutters and turning compost heaps need to be done mindfully. It is easy to injure yourself if the ladder slips or you put the garden fork through your boot.

Our green garden

The organic fruit and vegetables from our green garden are at the heart of our wellbeing. Food free from toxic pesticides and grown in compost and vermi-leachate from the worm farms is absolutely central. It is our desire to protect our lives from malignant neoplasms and the chronic diseases; that means a fresh look at lifestyle.

Freshly-picked the flavours are divine; you will never know just how much better until you begin to indulge yourself in food grown on your own land.

Eat greens for your eyes' sake whether you like them or not; needless adult-onset blindness is not a pleasant thought. Over ten million Americans are affected; and all those enjoying the commercial diet found in traditional supermarkets are vulnerable.

Curly leaf kale is good for the eyes.

When making recipes with lemon juice, as with many green salads, ignore the prevailing advice. Use the pulp too; that is where more than half of the nutrients are to be found.

There are literally thousands of important phytonutrients in our organic food; like beta-cryptoxanthin, the most powerful antioxidant known to protect our brains against the neurodegenerative diseases. Not just an apple a day but a citrus too; use the pulp. You are unlikely to find these carotenoids and many other gems in the highly-processed concentrate; it tastes awful in any case.


Legumes are the foods that enable vegetarians to get sufficient protein without eating meat, fish or chicken; or dairy products and eggs.

At our green home we specialise in many different legumes but queen of the table is the broad bean; they are also known as favas. They protect us from the ravages of Parkinson's disease.

We are not vegetarians but are trying hard to reduce our reliance on meat for protein, partly because of the way animals are reared today; but also the contribution they make to greenhouse gases and a shortage of water.

Rainwater storage is our other contribution to this growing nightmare in South Africa. First Cape Town and now Port Elizabeth have been in dire straits.

Broad beans

Broad bean pods

Broad beans are the first on our list, firstly because they are the only legume that are a complete protein with all the amino acids; and secondly since they are only edible if harvested and enjoyed freshly-picked.

Since they are difficult to buy, we make a call for some gardeners to become broad bean entrepreneurs who will be able to supply those suffering from Parkinson's disease; these legumes are the only common source of pharmacological amounts of the precursor of dopamine, the "happy hormone."

Broad beans on toast will provide a marvelous dish that can be prepared in a very short time; certainly don't pop them out of their skins.

"There is little to no benefit in taking vitamin or mineral supplements to prevent CVD, cancer or death."

- US Preventative Task Services Force

I am yet to meet someone who does not love freshly-picked green peas or climbing beans from the garden. They have pride of place, not least because they supply nitrogen to the soil, obviating the need for inorganic fertilisers.

Compost heaps are important at our green home; they help provide the humus that makes for increased uptake of water from the soil. Building and turning them is hard physical work but they remain central in our attempt to turn our garden into a Cyan Zone; where ten times as many people live to one hundred years old, whilst simultaneously caring for the planet.

In short if one wants to live long in the land, a garden has to be central; apart from anything else, taking time to smell the roses means less stress. It's being called forest bathing. 

Growing and eating food from one's own garden, especially more legumes like beans and peas is common to all five of the Blue Zones where ten times as many folk live regularly into vibrant old age.

What is a cyan zone  you may be asking. The colour is a mixture of blue and green; some would call it turquoise.

"There is increasing evidence that exposure to plants and green space and particularly to gardening, is beneficial to mental and physical health."

- Clinical Medicine (PMC6334070)[2]

Our green kitchen

What goes on in your own kitchen at home will have a far greater impact on your wellness and longevity than how good or bad your doctor is; and the pain and disability you may suffer from.

In our green kitchen we often boast about our compost bin; it too will give a measure of your well-being.

Compost bins are an important part of gardening, and how healthy you will be.

Brewing various beers and meads is a favourite occupation; do you know how to make merrylegs perry cider? It's not difficult if you have a glut of pears.

Spices and all things nice

Peppadews bucketful

Peppadews are one of the most interesting and profoundly tasty foods I have grown. They are simply a delight. It's not difficult.

I do not have the energy for it but you could make a few bob on the side out of a little peppadew cottage industry in your garden. They take up about a square metre per plant and produce in excess of 100 delicious, spicy fruits that are not too hot.


Summer garden kale.

This page is constantly being updated. It's all about the protection afforded by plants like kale and lettuce in a delicious summer salad; with copious amounts of olive oil and various condiments made using the pulp and the juice of lemons and limes.

Divine salad colours

These are the kinds of foods that protect us from the chronic degenerative diseases.

worm farms

Worm farms and the black plague are not so far-fetched. Madagascar had a serious outbreak in 2018. Whenever garbage is not effectually collected and properly treated then the rats that harbour bubonic bacterium will have a field day.

These confessions of a waste picker all started because of a need to feed the worms, only to discover there are totally other and new dimensions to dumpster diving. People too will eat what the greengrocer throws away.

Remember that water is the greatest enemy of the worm farms; they will drown if the tanks are flooded.

Our green Solar power

Our green solar power, harnessing energy from Mr Golden Sun as our grandchildren call him is a very large topic at this site. In countries with an unreliable grid that means batteries for storing the energy. Make your home resilient to the inevitable change that is coming upon our world.

It is time to go solar.

What is a professional is an important question to answer before setting out on a solar installation.

Lithium batteries

Lithium batteries at our green home.

Lithium batteries are still the best way to store electrical energy in the home. There are many new types coming onto the market but they at this stage are still more expensive and less proven.

These are astonishingly good; we are waiting for several consecutive wet days to see how they cope before going off the grid. Here is an update; we have used only 43 kWh from the utility in the last four years.

Should you put in a gas geyser or go onto a prepaid electrity meter is a question that has haunted us; we have finally made the decision.

The big hit in electricity prices should come into the equation when considering the financial viability of going solar.

The total unreliability of the utility in our village gave rise to drama on Town Hill.

There is a solution to load shedding and security sytems; it is as simple as replacing the small inadequate gel-cell batteries.

Electric vehicles

Jean in her new Nissan Leaf.

Electric vehicles are the future but they remain very expensive and not many are available in South Africa. In December 2019 we gave ourselves a much desired Christmas gift; a second-hand Nissan Leaf. Four years later it still has pride of place of all the cars I have ever earned.

Turning over a blue Leaf has taken on a different meaning this New Year.

But first an update on the general status of electrical vehicles in South Africa. The E-car has landed gives my take on the subject.

Servicing of E-cars comes into the equation when considering entering this brave new world. The costs are minimal except when you need a new battery.

There are no hints in this Warren Buffett interview what car he drives but this man is an inspiration to me; he is a world leader in the art of frugal living.

Our green rainwater harvesting

Harvesting rainwater remains near the top of the list of priorities at our green home.

Whilst it is true that the rain in industrial areas will absorbe some pollutants from the atmosphere, nothing compares with the micro-particles of plastic that are found in our municipal and most bottled waters; over 300 tiny bits per litre on average.

How safe is our drinking water is a very disturbing question to face.

Post-chlorination products too are highly carcinogenic; it was our desire to have a copious supply of free pristine rainwater straight from the tap in our home. There is plenty for the garden too.

Green rainwater harvesting is a building project that can be completed in about two weeks for an estimated cost of R50,000 in 2024.

At rain-water storage you can weigh more thoughts on the subject. We have been harvesting the manna from the skies for more than ten years; I would still do it no other way. A life without vicissitudes of the utility companies is a joy.

It is hard to believe but the average American consumes 5g of plastic from the water he drinks every week; that is the weight of a credit card.

Harvesting rainwater is not rocket science; we have found that storing it in an underground reservoir is the best way.

Cleaning the gutters at the end of autumn is a chore that isn't pleasant but should be done regardless of whether one is harvesting rainwater or not.

Hot water is best obtained via a solar geyser.

The microbiome

Beneficial bacteria, viruses and protozoa known as the microbiome inhabit different parts of the human body. However, should the environment get out of balance, their numbers decline and pathogens may take advantage of the situation.

Caring for the microbiome by fermenting many different foods is a central theme at our green home.

One such community of bugs lives in the armpit; raising the pH by using bicarb as a deodorant discourages those that cause body-odour. It is highly effective but does not reduce sweating.

The gut-lung connection and the coronavirus means there is real value in making kefir in our own kitchens. Probiotics prepare us for the day that we will be exposed eventually to this extremely virulent flu; and a host of other infectious diseases that bang continually on the door.


Planet Earth is in dire need of beekeepers, both hobbyists and those who wish to make it into a commercial venture; certainly worth a consideration at any green home. The startup costs are relatively small and the return immediate.

With one in four mouthfuls pollinated by our little friends, who will save the bees? It's a question every human should be asking.

Making honey mead has become very special; brewing a natural wine that acts as a probiotic and will not increase the likelihood of a malignant tumour.

Notice the synergy of all these activities and the contributions they make both individually and together at our green home; caring for our wellness and that of the planet.

Glass mulberry meadNatural wines do not cause cancer.

We should carpet South Africa with Spekboom not just for its ability to sequester carbon-dioxide from the atmosphere but also for the prolific nectar this beautiful bush produces.

Beautiful bouquets of flowers from the florist mean yet more misery for our landfills already totally overloaded with plastic waste.

Proper chickens

The English love their proper eggs from free-range and fertile chickens; that means a cockerel. Half of those little darlings grow up to be very randy and raucous young males; so what do you do with them? Why, set out the chairs and invite the ladies to come over with their knitting, of course; off with their heads.

The only problem is that my wife is a racist and will simply not touch that brown meat; and I still find it extremely difficult to kill a bird or any animal for that matter. Despite the tribulations of hens and roosters they certainly make a great contribution to our green home.

Farmers' markets

At farmers' markets you have a far better chance of getting fresh organic fruit and vegetables. Do not expect to get bargains because producing food without fertilizer and pesticides is hard work.

We support the Reko Farmers' Market in Hilton, South Africa. It certainly does contribute to our green home.
