What’s going on in That Yard?

This is the 100th post on That Blog. While the blog was started just over a year ago, That Yard has been a work in progress for three summers. Since permaculture practitioners say it takes three years for a design to come together and start functioning as a self-sustaining system, this seems like a good time to review what’s going on in That Yard.

The first summer was spent observing, learning about the site conditions, and planning for subsequent years.

In the second summer, several different plantings were established. These formed the nuclei for miniature ecosystems, including a prairie, a forest, and a rain garden.

In the third year, these ecosystems were expanded on, and remaining unconverted areas were turned into a Hugelkultur bed and a pond. Now the entire yard is planted with native species, except for a few oddly-shaped corners, which will be filled in next year.

All of this has been accomplished with no chemicals and no powered equipment. What have been the effects?

First, life abounds. At any given time, from early spring through late fall, multiple species of plants are flowering. These plants attract a wide assortment of pollinators, among them bumblebees and monarch butterflies. The yard has hosted at least 49 species of birds, and thanks to the pond, a pair of frogs has recently moved in.

There are lots of benefits for people, too. All those plants provide plenty of clean air for the neighborhood. They don’t need to be mown, eliminating noise and air pollution. They capture rain before it reaches the street, while taking nothing from municipal water supplies.

What remains to be done? In summers four and five, the new plants will continue to get established. As they do, the number of species flowering will increase, and the odd corners will fill in. Non-native species, such as buckthorn and garlic mustard, will be pulled out to help with this process.

Before long, the yard will be a healthy, mature system, providing a variety of benefits and requiring minimal work.

Like any kind of transition, establishing a natural yard can be difficult and messy. But success is virtually guaranteed, and the results are more than worth it!

What is an herb spiral?

Ask a permaculture practitioner to name a design pattern, and they’ll probably describe the herb spiral – a way of creating a lot of microclimates and producing a lot of food in a small space.

An herb spiral is built by piling up a mound of soil. Stones are then placed in a spiral pattern down the sides of the mound, and the soil between the rows of stones is flattened out. This forms a sort of spiral path, which serves as a planting bed.

As the name of the design suggests, it is customary to plant herbs along the spiral. The plants are placed according to their preferred microclimates. A species that likes cool, damp spots can go at the bottom of the shady side of the mound, while a species that thrives in hot, sunny, dry conditions can go on top.

By building up, the spiral creates a lot of planting space in a small footprint. It also makes plants easier to reach.

Building an herb spiral outside your kitchen door can provide you with fresh flavor all summer long.

What is a keyhole garden?

Every vegetable garden needs paths – if you can’t reach the plants, you can’t eat them.

The simplest layout for a garden is to plant in rows, alternating planting beds with paths. This design, however, results in a lot of space devoted to walking, relative to the space used for producing food. That’s not a very efficient way to garden in a small yard.

Raised beds are a little more efficient. Because they’re higher and easier to reach, the beds can be wider, increasing the ratio of planting area to walking space.

An even better way is a layout called a keyhole garden. This design features a circular planting bed with an open work space in the middle, and a single narrow path connecting the inside to the outside. By standing in the center and by walking around the outer edge, the gardener can reach all the plants to care for and harvest them, while not taking up any more space than necessary for paths.

This image compares traditional rows, raised beds, and keyhole gardens.

Keyhole gardens must be relatively small, since they only work if the gardener can reach the middle of the planting bed from either side. When more space is available, however, multiple keyhole gardens can be linked together in a pattern called a mandala garden.

By using space creatively, we can produce a surprising amount of food, even in a small suburban yard.

What is Earth Overshoot Day?

We all understand budgeting with money. If a household makes $50,000 in a year, then $50,000 is the most they should spend in a year. To spend more, they would have to overdraw their checking account or run up their credit card balance – practices that can quickly lead to financial disaster.

Ecosystem services need to be budgeted, too. The Earth “pays” us various resources, like food, wood, clean water, and breathable air. These resources continually replenish themselves, which is why we call them “renewable”.

However, even renewable resources only renew so fast. Each year, the Earth only generates a certain amount of the products and services we need. To budget wisely, we should make sure we aren’t using these services faster than the Earth can provide more of them.

Unfortunately, right now we’re not living within our ecosystem budget. Between last January 1st and today – August 8th – humans have collectively used as many resources as the Earth will produce in all of 2016. In other words, it’s taken us just over seven months to use up resources that our planet needs an entire year to generate.

That’s why today is called Earth Overshoot Day. But don’t mark your calendar for August 8th, 2017 – unlike other holidays, Earth Overshoot Day gets earlier every year. That is, we’re using up resources faster and faster, and wiping out the plants and animals that provide those resources, thus slowing down the rate at which the Earth can produce more of the things we need.

In 2015, Earth Overshoot Day fell on August 13th. As recently as 2009, it was in September. And in 1970, we just barely overspent our ecological income, using up a year’s worth of resources on December 23rd.

This isn’t a sustainable path. By taking less from the Earth, and putting back more, we can live within our ecological means.

What is a lasagna garden?

No, it isn’t a garden that produces the ingredients for a baked pasta dish. Rather, it’s a type of raised bed that is built in layers, like a lasagna.

The first step in building a lasagna garden is to choose a good location and put down a layer of sheet mulch.

Next, add layers of organic material, such as compost, grass clippings, fallen leaves, or old newspaper. A frame can help to hold the materials together, but isn’t strictly necessary.

A lasagna garden should stand eight to twelve inches above ground level. It needs to be built higher than this, though, because the materials will settle a lot as they break down into soil.

As with a Hugelkultur bed, a new lasagna garden should be watered thoroughly, to help the materials break down and to provide plenty of moisture for the soil. Once the lasagna garden is established, it will hold moisture well and need little additional watering.

Late summer or early fall is a great time to build a lasagna garden. Plenty of yard waste is available for building up the layers. The material will break down over the winter, and will be watered in the spring by rain and snowmelt. Then, it will be ready for planting!

Seeds and seedlings can be planted directly into the lasagna garden. A final layer of mulch – such as straw or wood chips – will help prevent unwanted plants from inviting themselves in.
