Here we are folks, plant life article number two ( and it isn't even about plants!)

Hot Off the Press

Last week I redirected some of my literary creativity into a new medium and produced an article for the Dunedin Botanic Garden's weekly column in the local paper, the Otago Daily Times. Each week a different D.B.G staff member is tasked with profiling a plant or horticultural concept that can be found on display in the garden. Keen to give it a go, I put myself forward and was assigned two articles. The first of which can be found via the link below.

Article- ODT

This is a topic I feel very passionately about and feel is very much overlooked in the world of amenity horticulture.A garden is more than the sum of its parts!

Enjoy!

Tannock House Vegetable Garden- R.I.P

Upon my return to Dunedin almost a month ago, I was dismayed to find that my wee vegetable garden that I had been tending to and snacking from before I left was, shall we say, past its best. I can't really complain though, having two consecutive growing seasons to experiment was an absolute treat. Bring on the third, I say! 

So just for a bit of fun, here are a couple of snaps that I took before Christmas charting the rise of the Tannock House veggie garden.

Once more into the Wiggy Wig Bush!

New Zealand is an island (well, two islands) and has been for millions of years. Geographic isolation has resulted in many an evolutionary quirk occurring within both the island’s flora and fauna and as it stands today 80% of the country’s trees, ferns and flowering plants are classified as ‘endemic’, meaning that they naturally occur no where else on Earth. One such quirk is the rather splendid and unusual growth habit known as Divarication. Divaricate plants have small leaves and wide angled branches that grow in a characteristic, interlacing ziggidy-zaggedy manner producing a dense, highly tensile shrubby mass. While plants exhibiting this form are found throughout the world, they are nowhere as prominent as within NZ’s flora.  Around 10% of the country’s woody plants display this growth habit with specimens occurring across 18 different taxonomic plant families. Bizarrely, certain plants, such as the Kōwhai tree (Sophora microphylla) have a divaricate form as the juvenile stage of their development before adopting a more conventional branching arrangement as they mature. A prime example of a plant with a strongly divaricated habit is our old friend the Wiggy Wig Bush (Muehlenbeckia astonii) with its highly geometric, molecular shaped branching.

A number of theories have arisen to explain the penchant for divarication of New Zealand’s plant life.  Some have postulated that the dense and tangled branch growth had evolved as a defensive response to the browsing of the now extinct Moa, a large flightless bird similar to the modern day emu. Indeed, such a theory would explain the juvenile divaricate habit of certain plants as once of a mature height they would no longer be at risk from browsing animals. Others claim that divarication aids plants in protection from dry and windy climatic conditions by acting as a windbreak, reducing transpiration from the plant’s inner leaves and limiting water loss.  The inner depths of a divaricate shrub also provide a hospitable environment for native lizards such as skinks and geckos. In return for acting as agents of fruit and seed dispersal, the lizards are provided shelter and protection by the interwoven branches of the plant.

Off the Road

Well, avid readers, I'm back! Following an extended summer jaunt that saw me successfully take in a good portion of New Zealand's South Island (and only exploding my van’s battery once) I have landed back in Dunedin once again to carry out the final two months of my placement. Though, admittedly, most of my time on the road was spent recreationally, I did set aside some time to look into a blog-worthy project that has been of interest to me since my arrival on these far flung shores. Two weeks into my time here in Dunedin, I heard about a family that had established and grown what was being described as a ‘Forest Garden’ at their home in the small coastal town of Riverton. A low energy input growing system based upon the ecological relationships of a forest, an established 'forest garden' is able to produce an abundant variety of perennial vegetable and fruit crops with a minimal amount of maintenance. The concept fascinated me with its unique combination of ecology, inventive design, biodiversity and practicality. After doing some more research, I managed to get in touch with Robert and Robyn Guyton and arranged a week’s stay with them in order to view their work first hand and help out in any way that I could. 

The Guyton Household- Riverton, NZ

As it turns out, very little help was required in the forest itself aside from a few small plantings- a testament to the low maintenance requirements of the garden! However, the Guyton’s food forest is just the tip of the iceberg in terms of their environmental endeavours and there was plenty to get my teeth stuck into! Since moving to Riverton over twenty years ago, Robert and Robyn have been instrumental in establishing a number of fantastic horticultural projects including a community orchard (and a secret guerilla orchard), an organic gardeners network, a living catalogue of heritage varieties of fruit tree specific to Southland, New Zealand and Riverton’s very own Environment Centre, a one stop shop for organic produce and information located on the town’s main street. Inspiring doesn’t even begin to cover my time in the company of these lovely and incredibly generous folks. Upon my arrival, Robert gave me a detailed tour of “the system” as he referred to it, which covers almost two acres surrounding the family home.

Meandering through the garden, it did not take long to become totally immersed (and a bit disoriented) within its wild beauty. The ground is thick with leaf and plant matter that is left where it is to decompose rather than being swept aside and turned into waste. Robert informs me that this process of heavy mulching with organic matter over the past 20 years has led to test sample of soil displaying a perfect balance of all nutrients apart from selenium (and that is only because the element is lacking in all of New Zealand’s soil). Beneficial perennial herbs form a healthy understory for apple, plum, peach, walnut and hazel trees dotted across the landscape. Each fruit tree has been selected and grafted by Robyn who delights in telling me their history as we pick and grade apples later in the week.  Scattered throughout the system also are currant and raspberry bushes that give off a bumper crop of soft fruit each year. All in all around 450 plant species are grown within the garden, many of them edible- all of them useful. There is no weeding to be done in the system either as carefully planned succession of plantings and lack of open cultivated ground keeps common weeds from taking hold. Pests and diseases are similarly notable by their absence. Thanks to the innate biodiversity of the forest garden, pests are predated on before they get to become a problem. Unlike many conventional gardens, plant are protected through solely natural means without needing to resort to toxic chemicals time and time again as a short term solution.

Deep in the Forest...

I believe that a lot can be learned from the Guyton's forest garden. It serves as a useful reminder that horticulture need not be a constant battle against plants and their natural processes but a joyful and beneficial undertaking, for both gardener and the environment alike! It is amazing what you can do when you don't have a lawn...

Not a blade of grass in sight!

I would like to take this opportunity to thank the Guyton family for hosting me and allowing me into their home. Your time was gratefully received. Long may your forest grow!

The Guytons and I.

                                                                               

On the Road

As those of you following this blog may have noticed, there has been a lack of activity of late. Fear not! I have been on the road living out of the back of my van for the past month or so and have had very sporadic internet access. I will be back in action as of the 24th of February and will have info. aplenty for you all. Cheers in the mean time!
