Arno's jungle on 2018-05-18

Backyard in the middle of May 2018.

My front yard and back yard provide the perfect practice ground for trying out new ideas. These pages document some of the ideas I have executed and the reasons for them. As with every design, with changes come new possibilities. Some ideas have proven not to work too well in the context of my garden. Those failures provide essential input on what could be tried next.

Background

When I bought the house in 2005/2006 with my former wife, the garden was ornamental. The previous occupants had planted some nice looking but inedible shrubs. There was a young fruit tree. The terrace was paved with concrete slabs and a major part of the garden was grass lawn. My partner took care of the garden and I helped.

After the divorce in 2013 I let the garden do its own thing. I did very little maintenance mostly because I could not be bothered. The result was a jungle. I liked what I saw. There was much more life in the garden.

In October 2016 I followed an online course: Oregon State University's Intro to Permaculture Design. This course was given by Andrew Millison. During the course I used my back yard to learn the different tools the course offered. The hugels are a direct result from this work.

In February 2018 I completed a Permaculture Design Course given by Rakesh "Rootsman Rak". Consequently I have started looking again at my front yard and back yard. I try to apply what I learned.

Design strategy

As shown in the introduction, the garden has gone though many iterations. Starting out I had zero gardening experience. The vision for the garden also changed significantly over the years. One thing I do note: over time, the designs have become far more informed by observation.

To present the current iteration of the back yard, I have retrofitted CEAP as the design strategy. This is to show where changes fit into the permaculture way of thinking and where improvements can be made.

Client interview

I believe the future of our species survival will depend on intimate knowledge of the natural world and our place within it. Permaculture is a strong basis for this knowledge. We need to deepen this knowledge in individuals and groups to ensure at least some of it will be passed on to next generations.

Our vision for the future is to start a farm and make it a beacon of learning and community. We are already doing this on a small scale in our house and our surroundings.

While a PDC provides learning in a broad range of topics, I find much more depth is needed to become a good permaculture designer. One of the goals for the back yard is therefore to gain as much practical knowledge as possible.

  • Everything gardens
    • use compost, green mulch, chop-and-drop
    • put vines next to support beams and trees
    • compost bin
    • invite ants, other soil creatures to set up shop in the garden
  • the problem is the solution
    • annuals don't work well under the shade of the tree → use plants adapted to forest floor or forest edge
    • snails eat leafy greens → most snails actually prefer eating dead and decaying material → use green mulch and harvest the snails that come to feast
    • lots of snails → invite more birds, animals and insects to eat the snails
  • yield is theoretically unlimited
    • jungle retreat
    • increased biodiversity
    • many interesting living things to discover
    • source of nutrition
    • source of education
    • source of inspiration
  • work with nature
    • plant the desired species in a spot and watch it find its niche
    • plants wander to spots they like better
    • use plants adapted to shady places for under the tree
    • reserve sunniest spots for annuals, more shaded spots for perennials
    • lead climbing plants up the tree for more vertical space
  • minimum effort, maximum effect
    • to get rid of grass → plant Fragaria vesca → watch it take over
    • compost bin is four pallets set on their side, easy to assemble, easy to take away if it had not worked

Holmgren principles

  • Observe and interact
    • watch the tree grow over time changing the vegetation underneath

    • harvest mirabels from tree
    • harvest berries from bushes
    • harvest annuals from garden beds
    • learn about nature: plants, animals, ...
  • Apply self regulation and accept feedback
    • annuals don't grow under the tree any more, change to perennials
    • water catchment took a few iterations to work out
    • experimenting with plants that will grow in a shaded understory
    • Allium ursinum (wild garlic / daslook) disappeared because we planted it in a place that was too sunny and had too many nutrients

  • Design from patterns to details
    • work from tree to smaller areas around it
    • work with existing structures as much as possible
    • water flows from high points to low points
  • Integrate rather than segregate
    • hugels provide nutrients, moisture and fungal trading networks for plants on the hugel and the tree roots underneath it as well as habitat for bacteria, fungi, invertebrates and other animals inside it
    • use as many of the seven layers of a forest
    • maybe connect up the compost bin and the hugels to create a fungal superhighway
  • Use small and slow solutions
    • all construction was done by hand using simple tools
    • compost bin

    • use of available edges
      • on wall and in tree: Hedera helix (common ivy / klimop)
      • on fence: Hydrangea macrophylla (bigleaf hydrangea / gewone hortensia)
      • in tree: Rubus phoenicolasius (Japanese wineberry / Japanse wijnbes)
      • on side of the compost bin: nothing yet
    • marginal plants include growing a number of common weeds
    • adding edge by using hugels and raised garden beds
    • using the edge of the hugel as the overflow gutter
  • Creatively use and respond to change
    • gardening is an ongoing exercise in responding to change
    • tomato seeds geminating on the compost pile? Let them grow! And plant a pumpkin there as well.

Maintain

Evaluation of growing season 2017

  • What went well?
    • Growing tomato's was a great success
    • Mirabelle harvest was huge: 40kg!
    • Cucumbers were late developing, good harvest
    • Raspberry had two harvests
    • Slugs had a great party (unfortunately for us)
    • Water harvesting went well after initial hiccups
    • Compost bin worked
  • What would I do differently?
    • More focus on perennials and self-propagating plants: berries, tubers
    • Guide tomato plants earlier using some sort of enclosure
    • Let plants grow stronger indoor before planting outside
  • What is my vision?
    • Incorporate front yard as well
  • What is my next step?
    • Observe newly planted berries next year
    • Add more planting containers to more effectively use available sun
    • Try a few different annuals
    • Try polyculture and overlapping plants in time
    • Continue trying new things

Evaluation of growing season 2018

  • What went well?
    • Indoor sowing gave us
      • three tomato plants,
      • three pumpkin plants,
      • two cucumber plants,
      • two aubergine plants,
      • a batch of Ocimum basilicum (basil / basilicum) and
      • a batch of Eruca sativa (rocket / rucola).
    • To combat the drought, we used the grey water from the kitchen to water the tomato and aubergine plants. Those plants thrived for the most part while others suffered.
    • The A-frame construction with bamboo worked well for the Cucumis sativus (cucumber / komkommer)
    • Helianthus tuberosus (Jerusalem artichoke / aardpeer) grew to 3m height with a huge cluster of tubers produced.
    • Compost heap has turned into very good compost.
    • The Humulus lupulus (common hop / hop) in the front yard turned out to be female. We harvested and dried a small batch of hops.
  • What would I do differently?
    • Due to the drought, the berries on the hugels died. I would plant them deeper in the soil the next time.
    • We should try to take the top out of Solanum lycopersicum var. cerasiforme (cherry tomato / kerstomaat) to keep its growth in check. This is also better for the integrity of the bamboo construction we made to guide the plants.
    • Bring the grey water further out in the garden as well not just in the planters closest to the back door.
  • What is my vision?
    • Try scaling this up to an allotment or community garden
  • What is my next step?
    • Get an allotment (done!)
