Winter and early Spring are a great time to get those trees in the ground, giving them a good chance to settle roots and prepare for the dry Summer months. As climatic shifts and global weirding looks set to threaten our food security, biodiversity and social cohesion, are community orchards and more planting of fruit and nut trees the answer?
The dominant crops we plant are annual - planted, harvested and replanted every year. Perennials
come back every year with similar yield and higher rates of carbon sequestration. Staple foods from
trees include fruits like bananas and breadfruit, oil rich avocado, and nuts like macadamia and
hazelnut. These trees can be a part of forest farms, multi-level agroforestry or intercropping
They can also reverse erosion, runoff and create higher infiltration rates for rainwater. You can grow them on steep slopes and in a variety of soils while they also require lower inputs of fuel, fertiliser and pesticides. If you create a diverse orchard, the system can often become self managing, creating fantastic habitats for wildlife and generally encouraging greater bio-diversity than parks and gardens.
Which is why urban, community orchards could be such a nifty solution to feeding and supporting people in city environments. Planting orchards in urban areas increases tree coverage, the benefits of which include more shade coverage and cooling effects as summer temperatures increase. Increased rainwater uptake and a carbon sequestration rate of 3.34 tonnes per hectare, every year, for decades, perennials produce 2.4 times more food than annuals grown in the same area. They cost 40% less to produce than annuals (trees just kinda grow and fruit with very little input required). There is always abundance and enough to go around when you have mature perennial tree crops producing.
We visited Mel, one of the founders of Wellington's first urban community orchard, now mature, busting with life, insects, fruits and people and positioned in a busy walkway next to a school in Brooklyn. The project started by guerilla planting available space, asking for permission from Council while proving the case. All of the trees had stories attached to them. There was still fruit on the trees because the community knew to fill only their pockets, not their bags, so to leave some for others to enjoy. Kids picked fruit for their lunchbox on the way to school. It felt like a wonderful place to go and bump into people, learn about what likes to grow in that area and find inspiration from the place and purpose. We take you for a look around the orchard in our short documentary, Growers of Aotearoa, with a sneak peak below.
Leafy greens provide us with some really vital micro-nutrients and are so important in the transition to
increasing the plant based content of your diet and good health. Winter is a perfect time to grow them
and Summer, the perfect time to collect their seeds, ready for the next planting season.
Kale, as an example, is considered one of the most nutrient dense foods on the planet, high in Vitamin K, A and C and also anti-oxidants that help maintain great eyesight amongst other things. Other greens are just as beneficial. Many can be grown year round and easily turned into stunning, nutritious and tasty meals. You're basically eating for free, with minimal effort.
Maybe what you didn’t know, is that according to recent NZ based research, the case for growing your own
has additional benefits to your long term health, and that of your friends, family and global neighbours.
The benefits of some real, meaningful climate action when you figure the figures out.
According to Otago University, leafy greens (so your kales, silverbeets, mesclun, lettuce, spinach, microgreens, cabbage etc) have just over 3kgCO2e/kg (or 3kg of carbon emissions for every kilogram of greens)..which means per weight of leafy greens, grown at home, nutritionally better for you, fresh from your garden, you save 3 times their weight in emissions!
Source The MouthfulDoesn’t sound like much? Our family of four ate 1kg (easily) of homegrown leafy greens this week. There’s enough amongst our 4 cavolo nero plants, 4 collard green plants, mesclun, kale and herb pots to harvest lots more than this. Every week.
Now here’s the really interesting bit. In a 2017 study in Santa Barbara, researchers modelled the
potential for carbon sequestration in a vegetable garden, compared to other options for your outside
space like lawns.
In the UK, pictures emerged just before Christmas, as the result of a new Covid strain and unexpected
lockdown, of trucks filled with supplies parked on motorways. They were unable to reach their final
destination and UK citizens became instantly aware of food security issues in a country dependent on
overseas food exports.
This week, Auckland entered Level 3 lockdown, with the remainder of New Zealand in Level 2 and an uncertain future as we head towards Autumn and Winter when the bugs and viruses love to thrive. Wherever you’re from, whatever your background, food is something which links all of us as human beings, and animals and plant life. This common connector is a need for every living thing. When it is threatened, our survival instincts have to kick in - it’s evolution. It’s why we’ve survived for this long. And it’s why many countries are experiencing a boom in demand for seeds and seedlings, in recognition of our animal instincts to adapt and survive. To have the capacity to grow some of our own food, improve food security and sovereignty alongside the ability to avoid reliance on supermarket shopping.
Seeds, the embryos of plants and trees, and their supply are globally largely controlled by only a few
corporations. After mergers, 4 dominant companies control over 60% of seed markets.
Our indigenous cultures, marginalised and colonised, know how important it is not only to preserve seed but
also to select the best plants which have adapted to the unique local environment. Their close connection
with the lands, plants, water, animals, sky is all about observation and preservation for survival. The
wealth of different kinds of corns, uniquely adapted for some of the harshest climates in the world are
just one example of the importance of diversity as we enter a climatically uncertain period of human
history. Indeed the Native American Food Sovereignty Alliance state "Seeds are a vibrant and vital
foundation for food sovereignty, and are the basis for a sustainable, healthy agriculture. We understand
that seeds are our precious collective inheritance and it is our responsibility to care for the seeds as
part of our responsibility to feed and nourish ourselves and future generations." There is untold and
unrecorded bio-diversity remaining. Grandma’s lemon tree, Great Grandpa’s pumpkins. Perhaps even more so
in Aotearoa where we are GMO free and in gardens, pots and communities there is huge potential resource
of open pollinated, heritage seeds that have evolved with us over the last few hundred years to perform
beautifully in our climate. Although there are a few seed suppliers here, much our seed comes from
hybridised varieties bought on the international market from the big suppliers.
PlantMe.io was designed, in part, to record, track and share real-time information on which species of plants do well where, while also making it really easy to trade, buy or sell a wider range of heritage and open pollinated plants and seeds.
