HERE ARE THE RESULTS FROM THE FOURTH YEAR OF OUR MARKET GARDEN POLYCULTURE STUDY. THIS STUDY LOOKS AT THE DIFFERENCES BETWEEN GROWING ANNUAL VEGETABLES AND HERBS IN POLYCULTURES VS GROWING THEM IN TRADITIONAL BLOCKS.
In this post you will find an overview of the trial garden and the polycultures we are growing, a description of what we record and the 4th year results from the trial. You can find results from previous seasons here.
First of all we’d like to say a huge thank you to the team of volunteers that joined us for the study this year and that make it possible for us to carry out our experiments and research. It was a pleasure to work together with you. Thank you Victoria Bezhitashvili, Angela Rice, Malcolm Cannon, Elise Bijl, Alex Camilleri, Daniel Stradner, Emilce Nonquepan, Ezekiel Orba and Chris Kirby Lambert.
It was a great a mix of people from all over the world including university students, a crypto fund manager, ex-nintendo web editor and market gardeners. Thank you all for your valuable input, it was our pleasure to host you and we look forward to seeing you again some day.
In crop gardens, we sometimes get into a spatial race with weeds, and the solution is to replace the weeds with “designed weeds” to take up the space. This can be done with green manure mulches to fertilize the gardens and supply quality mulch. This is an example of how understanding the inner workings of weeds allows us to harmonize with natural systems to both repair the earth and create production for ourselves.
It’s important to understand that the term “weed” is applied to any plant that isn’t wanted in a particular area. While we now call dandelions weeds, they once were sought-after greens. Banana trees are so prone to take root in the tropics that someone might consider them a weed, removing them from the yard, though they are the best-selling fruit in the world. The point is that just because we call a plant a weed doesn’t mean it lacks value. “Weeds” can be useful, or they can be prevented. Often, it’s us, as cultivators, who make and foster these choices or pick our small battles.
Mulch – The best way to have a weed-free garden is to prevent them in the first place, and organic mulch is probably the best way to go about that. Thickly (about 5-10 cm) mulch gardens with straw or leaves to effectively suppress weeds, and those weeds that do make it through are much more easily pulled. Not only will mulching help with weeds, but it’ll reduce the need to water, support soil life, and prevent erosion. Ultimately, the mulch will break down and continually replenish and improve the soil.
Paul Alfrey from Balkan Ecology Project shares with us his observations and thoughts in regards to a visit he made to a farm he designed and how it slowly developed into a polyculture of fruit trees, aquaculture and vegetable gardens.
Last week Dylan and I set off on a road trip to discover the flora and fauna of the North East of Bulgaria. Our first stop was to Catherine Zanev ‘s farm in Todorovo, North Bulgaria. As those of you familiar with our project may recall, this was a farm I designed in 2013. I had not visited the place for some time and was very excited to see how the plans had emerged into reality.
Catherine’s goals for the plot were to create a polyculture farm with focus on producing fruit for juicing, to include vegetable production for a CSA (Community Supported Agriculture) scheme and to experiment with dye plants. The design was complete by 2015 and implementation began that year.
The design concept for Suhi Dol was to create an agroforestry system of “Belts” that are comprised of mixed species fruit trees, soft fruits and nitrogen fixing shrubs planted in “Rows” under-storied with support plants, herbs and perennial vegetables. Between the rows are the “Alleys”. The Alleys have potential to be used for growing hay, cereals, vegetables, herbs or rearing pasture raised poultry such as chickens or turkeys. Integrated throughout the belts and around the perimeter are various beneficial habitats to enhance biodiversity. The designed system is an elaboration of Alley Cropping and is based on tried and tested models of our small scale forest garden systems scaled up.

In the Northern Hemisphere, the balance of light is turning ever more towards darkness as we approach the Autumn Equinox. This is following a summer which in many places was unusually hot and dry(1, 2). This is perhaps not unexpected; climate change scientists have been predicting extreme temperature spikes for a number of years(3). However, it seems that a lot of farmers were nevertheless unprepared and many crops have been lost(2). Such occurrences can be seen as unfortunate; but can also serve as lessons for us. When you look at the factors exacerbating aridity, it seems clearer than ever that industrial farming is ill-equipped to deal with adaptation. This article will explore a little what happened in the heatwave, particularly in the UK and look at an example of a permaculture site which survived unharmed.
Throughout Europe, rainfall in the summer of 2018 was so low that many places were reported as having droughts. While some of the affected areas of the drought were wild places, such as the forest fires which swept through the coniferous forests of Norway and Sweden in June and July(4), the main losses were from the farming industry. Both Lithuania and Latvia declared national states of emergency in July(2, 5). Germany and Poland were reported as experiencing severe losses in wheat production(2), with many farmers in Germany resorting to destroying their crops since they did not have the resources to continue watering them(2). Many cattle farmers, such as in the UK, had to use their winter supply of animal food to feed their cows(6), since the grass had all withered and dried, creating a temporary solution and more problems in the months to come.
