Building beds with bricks

The mulch-generating polyculture for Mortal Tree’s PASSIVE garden system is going well. It’s the bed in Foundation for a future I am establishing with bricks.*

The intent for this bed, per A bit blunt method, was to shift the rocks every couple of months to kill off the grass underneath. This worked pretty well for most of the bed. I shifted the bricks in July and made a final small shift about a week ago. Above is the freshly shifted “mulch” around an amorpha.

I also tried covering a small part with grass mulch in May last year, and this took care of any weeds growing through the cracks. Below is the planting now. Like most fun times, there is a mess to clean up afterwards. This bed had a lot of fun last year. What you see is actually mulch I applied, the healthy comfrey, and some amorpha interplanted. I plucked out the little bits of green quackgrass, and look forward to some very lush, beautiful growth here come summer.

I plucked out the quackgrass when I shifted the rocks. Because they block sun and moisture loss, the rocks encourage the quackgrass to grow shallow, allowing me to just pick them up rather than pulling them. What roots did grow deeply are easily pulled because the soil is so soft under the bricks.

 


This soil conditioning is one if the main perks of using rocks. The soil life is everywhere, with centipedes, worms, spiders -even at this cold season. Soil between the bricks which heaved from the freezing over winter is unbelievably friable. It looks like it has been tilled.

Considering how low this soil is in organic matter, with a clay-coal base, with no amendments like sand or ever even being tilled before, I am very excited to already have such results. The moisture and soil life have brought it so far because I have created the right habitat, covering the soil. The organic matter is starting to accumulate.

Above are some amorpha leaves dropped last fall, which likely have brought in nitrogen the system formerly did not have. The plants were already beginning to nodulate in their pots when I planted them last year. If you would like to learn more about how I ensure they make nitrogen and get off to a good start, I have some notes here on Growing amorpha.

I also harvested some of the comfrey leaves last year, which I left around the plants I harvested from. This is breaking down into gorgeous soil, bringing in carbon the system did not formerly have.

Pictured is some broken down comfrey from a larger patch in the food forest. This new patch should be producing similar soil in the near future. It’s already well on its way.

 

*This could have been done with some large piece of canvas or the like, or a large piece of plywood. One of my clients decided to try clear plastic just to block water, which was still effective at removing the plants underneath.

The Garden of Mortal Tree

Such gardens arrive after some years of trials, where species themselves indicate their preferences, often in defiance of the dictates of literature. It is fortunate indeed that plants cannot read!

-Bill Mollison Permaculture ll

The sun bleeds a hotter light as it sets in the west, and this slope leans into it. It’s face to the setting sun, backed by trees to the east that swallow the gentle light of morning, days begin in shadow that lingers almost to the heat of midday only to be seared by the red light of evening.

The plants grow from these elements. Red-tan brushes of broomsedge grass (Andropogen) speckles the front in tall clusters like an artist’s idle tools, while at the back, messes of honeysuckle cling on piles of logs below scraggly chokecherries. Near the center, in contrast to the lush green Catalpa tree down the hill, stands the skeleton of what was once an apple tree. This is Mortal Tree, the sun scorched slope next to my house that’s becoming a vibrant, lush, productive food forest.

You might say I’m starting from scratch on this fourth acre of scrubby land; but I don’t plan on doing it alone. I know that every plant and tiny animal living here intends as much as I do to make the place burst with life. The aim of all nature is to create more life. My aim is not to take over, it’s to encourage and strengthen the process already at work. All this through carrying out a design.

Design works for me as the bridge between growth the garden wants, and yield I want. The more my design mirrors nature’s design, the more successful the project will be. In Mortal Tree, that design is a self-sustaining organism, every part interacting to make the whole, every part feeding the others, in care and nutrients, demanding little intervention from me.

Mortal Tree is the center of this design. Paths radiate from this point in fractile, lightning-like arms, and around this point the intensive planting starts -at the “nucleus” of the garden, growing out. The rest I let grow wild, mowing the grass and weeds with the quiet swing of my scythe, gathering excellent mulch. This mulch is fertilizer, moisture retention, and a tool for clearing space my edible plants and fruit trees need. It’s my main tactic, directing free growth of the ecology into my designs of hungry crops.

I’m experimenting with a no-till grain patch, fine-tuning PASSIVE gardening, enjoying the productive beauty in polycultures full of fruit trees and perennial vegetables. Nut and more fruit trees are scattered through the wild growth further down the hill that would perform far better if I had the mulch for them, but there lies my biggest problem:

It’s easy with the desire to power more plantings to overtax the free growth, and damage this delicate ecology. The current design has its limits. Over time, the area of free ecology I harvest for mulch is becoming smaller than the area producing food. What will happen when the need for fertility is greater than the supply?

I watch for what the garden offers. Mirroring the designs of nature in the yields, the design is improving. I’m using running plants to manage weeds, plants that produce massive amounts of mulch in the organized plantings to cycle nutrients and provide cover that protects the ground, and nitrogen fixers that can meet high demands of the hungry production plants. Slowly but surely, the two ends of the equation -wild carefree and productive, labor intensive -are drawing close.

I have to remember design is only so good as the nature that informs it. Nature is only so good as the life that fills it. No matter how refined my designs become, they are still nature. They house the light that bleeds from the sun, stretching up as growing plants, spuring on change in every aspect. Sometimes that change is good, sometimes not so good; but with the hope of achieving an ever more harmonious design to harness this light, through the changes each day brings, this garden, and its designer, lean into it.

For those of you new to this blog, “The Garden of Mortal Tree” used to be my About page, but after placing it in the Visual Archive, it fell out of existence. This is a major overhaul of that page that better reflects the present Mortal Tree.
