It’s hot and dry already but we have not yet started irrigating the fruit trees. That could change in the coming weeks. In the meantime we’re enjoying a good fruit set in part thanks to our resident bees. These are early plums that will be ripe in about a month from now.
Additionally, we’ve got plentiful grapes, apples, pears, peaches, guavas, olives, figs, feijoas, and for the first time quince. Flowering on the avocados is massive so we are hoping for good cross pollination there.
We’ve also had excellent germination of the Black Boy peach stones. We’ve potted up over 50 and still going.
On the animal front we’re up to about 60 muscovy ducklings hatched along with 8 goat kids. One of the kunekune sows is pregnant and due in the next weeks. Chooks laying up a storm with a broody hen sitting on a dozen Wyandotte eggs.

4-Dimensional Design: Master Class
23rd April, 2020
Kaitiaki Farm, Whanganui
On our farm it takes a month to cut down a tree, six months to build a garden bed, and two years to plant avocados.
Before and After
Building Beds
Time is the 4th dimension, and using it to our advantage saves effort, money, and fossil fuels while establishing and operating highly efficient and regenerative systems. Designing in 4 dimensions maximizes the value of available resources and minimizes waste as well as the need for heavy equipment and a fat wallet. It’s working smarter instead of harder.
In five years we have transformed a worn-out horse property into a fully integrated permaculture farm on a shoestring budget and essentially without the burning of fossil fuels. We engage a regenerative approach to food production on 5.1 hectares on the outskirts of Whanganui.
The programme includes: water management; soil enhancement; wind protection; animal management; annual gardening; successional planning; integrating systems; off-farm inputs and outputs; other stuff we do.
1 pm to 5:30 pm. Afternoon tea included. $55 p/p, $85 couples.
Dinner and overnight accommodation available before the PINZ Annual Hui.

When it comes to fruit trees, I have always put disease-resistance as a top priority. Here are two peach trees planted four metres apart.
The left-hand one is not particularly disease-resistant. I think it was given to us four years ago and I cannot recall the variety. You can see it is suffering from curly leaf, which reduces photosynthesis and overall vigour.
The right-hand one is a Black Boy peach. We have grown them for eight years and have never had curly leaf. When growing organically, it helps to have cultivars that are less vulnerable to plant diseases.
Plums, like the one pictured below, seem to be highly disease-resistant.
We have eight different varieties and have never had any problem with disease.
Plums are nice, but I do like peaches more. We have about 30 Black Boy peach trees in the ground that produce deep purple fruits.
We propagate them from the stones and sell them locally to those interested in low-maintenance, beautiful peaches.
We also grow disease-resistant apples. Apple varieties reported to have higher resistance include: Liberty, Monty’s Surprise, Belle de Boskoop, Peasgood Nonsuch, Priscilla, Akane, Captain Kidd, Lobo, and Reinette du Thorn.
Avocados are another story entirely. They are known to resent wet feet and suffer from phytophthora root rot. Soil conditions and/or mounding and drainage seem to be the most important factors for preventing stress in avos. Those shown below are stressed from being in pots to two years (a long story), but you can see the new growth forming at the tips. We planted them last autumn in a area with free draining soil, but also added small mounds and drains to be extra safe.
The avos below come from the same order three years ago but went in the ground straight away.

An amazing ‘teachable moment’ occurred recently regarding the concept of micro-climates. The “Black Boy” peach stones have been in sand – black sand from the west coast of New Zealand – for the winter. This is our germination strategy.
About four weeks ago, due to changing seasonal sun angles, morning sun reached under a shed roof and struck one small part of the beds. The resulting warmth caused early germination of five seedlings in one little spot. Only now are stones germinating in the rest of the beds.
That teachable moment gives way to larger discussions on micro-climates and how they can be embraced, designed and improved. While our market gardens are out in the open and often take heavy winds, we have a smaller ‘kitchen garden’ protected from the prevailing winds that also benefits from the ‘sun trap’ effect created by the home and carport.
We shifted the herb garden to this north-facing location in the car park. Most herbs love hot and dry conditions, as does the dog.
Similarly, these grapes grow in a north-facing sun trap that is also protected from the prevailing winds. Additionally, most of the leaves are kept dry by the shed roof, which reduces the chance of moulds and fungus growing on them.
Plants in the nursery receive morning sun but are protected from midday and afternoon sun in the summer.
The potting bench also receives morning sun but nothing else. This is good for transplants and hardening off purchased seedlings grown in hot houses.
With heavy soils we have struggled with where to plant citrus. The solution was to build up a “hugel-mound” to improve drainage and increase soil carbon, and to site it in a spot protected from the prevailing winds by existing lacebark and recently planted tagasaste.
While micro-climates often seek to achieve protection from the wind, there are instances when the opposite is desired. Evapotranspiration beds seek to draw moisture out for the soil using plants and a windy location. This from Wikipedia:
Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth’s land and ocean surface to the atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent loss of water as vapor through stomata in its leaves. Evapotranspiration is an important part of the water cycle. An element (such as a tree) that contributes to evapotranspiration can be called an evapotranspirator.[1]
Below is a sketch of a mounded ETS bed for grey water treatment using biomass willows and carex grasses. The idea is that the willows grow rapidly in the presence of the nutrients in the grey water but transpire excess moisture to the atmosphere. In winter when the willows are dormant the grasses take over the transpiration task.
By understanding micro-climates we can use them to our advantage. These are examples of using the permaculture principles: Observe & Interact, and Design from Patterns to Details.

A recent poll reveals water pollution is the top issue of concern in New Zealand. Climate change ranks not far behind.
Here are a pair of articles I have written for NZME (the Whanganui Chronicle) about how we can use good design to address both issues while building more resilient farms.

“All water has a perfect memory and is forever trying to get back to where it was.”
These words, attributed to Toni Morrison, have been echoing in my mind ever since I heard them in a recent tribute to the late poet. In one sentence she’s able to explain the hydrologic cycle, surface water runoff, groundwater movement, flooding, land drainage, waste water systems design, guttering and spouting, and even spilt milk.
The best I’ve come up with is “Water never lies.” That’s how I help our farm interns understand topographic landforms, overland flow paths, drainage and swales.
I’ve always been fascinated by the way water moves across the land – one of those kids forever playing on piles of soil with buckets of water. I had great difficulty learning to read at school but somehow could read the landscape effortlessly.
When introduced to topographic maps at age 15, I took to them easily as my classmates floundered with the concept. Contour lines sprang into three dimensions before my eyes while peers saw them only as so many squiggles. They scored A’s on spelling tests as I scored C’s.
For the next decade I spent a lot of time trekking and trip leading, and in one instance relied on my map reading and navigation to lead a group of students out of the Smoky Mountains during a freak spring snowstorm that dumped over a metre in 36 hours.
It was not long after that when my understanding of landforms took a leap forward one evening at a presentation by a local naturalist and university lecturer, Tom Wessels, who had just published a book: Reading the Forested Landscape: A Natural History of New England. Wessels helped me understand the role that life plays in helping shape the landscape and specifically the role of trees.
Not long after that I spent my life savings on a small farm in rural New Hampshire that consisted of steep slopes, glacial till, a 220 year-old farmhouse and pit toilet. It was exceptionally cheap, but served as an invaluable tutor over the next eight years as I floundered toward the good life.
These are the memories that played across my mind last month while planting poplar poles on a hillside above Purua Stream in Okoia. Having already planted 125 on our land over the last four years, I was able to take my time and carefully choose exactly where to place these last 15.
Extreme weather events worsened by climate change were also on my mind. The overriding goal for our small farm is resilience to both heavy rainfall and drought. By planting more trees we address both, but this is only part of the equation. The other parts are shrinking our carbon footprint and sequestering CO2 from the atmosphere.
Along those lines we’re planning to build a super efficient dwelling along with an innovative wastewater treatment system. Passive solar home design is well recognised so I won’t address it here but instead will focus on water.
Much of rural New Zealand suffers from water pollution but it’s not just cows. Older septic systems are failing and because of the high cost of upgrading to modern standards many people choose not to. A friend recently told me how bad the situation is.
Regular Chronicle readers will know that I’ve been writing about eco-thrifty approaches to building and renovating since 2011, and this is no exception. Having studied rural wastewater systems intensively for the last year I’ve adapted a European design to local conditions that addresses not only treatment for health and environmental standards but also carbon capture from the atmosphere.
In most cases wastewater is considered a pollutant and disposal is all about mitigating negative effects. I take the opposite view: it’s a valuable resource that should be harnessed for positive effects. This perspective represents a shift from what designer William McDonough describes as moving from “eco-efficient” to “eco-effective.”
Eco-efficiency is about being less bad while eco-effectiveness is about being good. Which would you prefer?
Additionally, the wastewater design is more affordable to build and has a much lower carbon footprint than others. That is the type of win-win-win approach the world needs in these turbulent times, because water never forgets and nature bats last.

The New South Wales government has announced it will spend $10 million to relocate native fish from the Lower Darling, which is experiencing low water levels and facing a long Australian summer with little rain forecast. Researchers indicate the causes are climate change and water extraction by irrigators upstream, resulting in an expensive “Noah’s Ark” type intervention funded by tax payers with no guarantee of success.
This is the type of lose-lose-lose situation humanity increasingly faces worldwide: environmental disruption accompanied by poor resource management resulting in an expensive Band Aid response.
Observations suggest these scenarios result from a failure to connect the dots or see The Big Picture. This is often called “reductionist thinking” or “tunnel vision.” It is the opposite of holistic thinking, and leads to a whole lot of costly mopping up afterwards. It’s a waste of time, resources and money. I hate waste!
The most effective way to address waste I have come across was popularized by William McDonough as Cradle-to-Cradle design in which his motto became “waste equals food.” A fortnight ago I introduced how McDonough designs with the goal of “eco-effectiveness” rather than “eco-efficiency,” or, in other words, being good rather than being less bad.
This approach to design requires a holistic perspective and a clear set of desired outcomes. When I design systems I seek to achieve the following: robustness, resilience, effectiveness, affordability, easy replication, and low resource input.
Take wastewater for example. In most cases it’s considered a pollutant and disposal focuses on mitigation. I take the opposite view: it’s a resource that can be harnessed for positive effects.
I’m in the finishing stages of designing a land application system from greywater that turns waste into food by using the effluent to ‘fertigate’ (fertilize and irrigate) willows* and other plants as part of a greater land management plan on our farm that involves growing food, sequestering carbon and building resilience to climate change. This approach to farming is called regenerative agriculture.
Central to our management plan is growing more trees and feeding them to goats while protecting slip prone hillsides and unstable stream banks. This is a win-win-win farm plan in and of itself, but the greywater design adds to the overall productivity and resilience of the land while offering affordable, effective replication on other properties as needed.
The system addresses environmental challenges in these ways:
1) By using coarse woodchips instead of mined aggregate as the bedding material, the carbon footprint of building the system is reduced through eliminating the need to mine and transport aggregate over potentially long distances. Woodchips, on the other hand, are a local resource everywhere in New Zealand and can be processed and transported using relatively little fuel. Additionally, aggregate is a non-renewable resource while woodchips are renewable.
2) While serving as an aerobic media for the biological treatment of greywater the woodchip bedding material is stored as a carbon sink.
3) Fast-growing willows sequester large amounts of carbon from the atmosphere while also taking up nitrates and phosphates from the wastewater.
4) The system is designed to be affordable and to encourage those living rurally to engage in a lower cost upgrade rather than continuing to use substandard systems or upgrading to an inadequate system. Redirecting greywater takes pressure off existing wastewater systems and extends their lives, thus reducing costs and dispersing wastewater over broader areas of land. (It’s possible this approach can also be used for stock effluent.)
5) Willow branches are fed to stock (in our case goats) which takes pressure off grazing during summer months and helps prevent the need for buying in feed during droughts.
In a nutshell, this land application system is easy and inexpensive to build; adaptable to different soil conditions; replicable and scalable; low in embodied carbon footprint; and, increases the productivity of farmland while sequestering atmospheric carbon. How many wins is that?
