Chapter 2: Planting, Implementation, and Facilitation
Now that we've established the vision and principles behind Miyawaki forests, it’s time to transform those concepts into action. Planting a Miyawaki forest is an exciting, hands-on process that blends ecological science with practical skills. This chapter will guide you through the process, step by step—starting with selecting the right plants and ending with engaging the community in your project. With the right approach and a little effort, your Miyawaki forest will take root and thrive, bringing long-term ecological and social benefits to your area.
Choosing the Right Plants
When it comes to Miyawaki forests, plant selection is the backbone of the entire project. The biodiversity and resilience of your forest depend on choosing the right mix of species. This process involves considering native species, layering plants to create a diverse ecosystem, and ensuring your selection supports local wildlife and promotes soil health.
Work with Local Experts
Choosing native plants should always be your first priority. Native species have evolved alongside local ecosystems and are best suited to the climate, soil, and pests in your area. That said, plant selection is a nuanced process, and collaborating with local experts is key. Consult with ecologists, environmental consultants, and local forestry specialists who are familiar with the natural plant communities in your region. Their input will be invaluable in selecting plants that are well-suited to your site’s specific conditions, whether you're planting in a wetland, forest edge, or urban area.
In addition to native plant specialists, consider reaching out to local universities, botanical gardens, and nonprofit organizations. These groups often have extensive knowledge of the region’s flora and can help you source seeds, seedlings, or even offer advice on species that thrive in particular microclimates.
Biodiversity is the Goal
A Miyawaki forest thrives on diversity, which mimics the natural ecosystem that once existed in the area. The more biodiversity you can incorporate into your plant selection, the better your forest will perform in the long run. A balanced mix of species—including trees, shrubs, grasses, and ground covers—helps to establish a robust ecological web, improving soil health, water retention, and air quality.
Think about planting species that occupy different ecological niches. You’ll want canopy trees, mid-level trees and shrubs, as well as low-growing ground cover plants that will work together to create a multi-layered ecosystem. For example, nitrogen-fixing plants can be used to naturally enrich the soil, while flowering plants will attract pollinators. The goal is to create a rich tapestry of plants that not only thrive together but support the entire ecosystem—starting from the soil up.
Sourcing Plants Locally
When sourcing your plants, always look to local nurseries or seed banks that specialize in native species. The closer the plants come from the actual region where you are planting, the better. This ensures that the species are genetically adapted to your area’s specific conditions and are more likely to succeed in the long run. Consider working with local producers who grow plants organically, as this minimizes the risk of introducing pests or diseases into the soil.
If your budget is tight or if native plants are hard to find, consider growing your own seedlings from locally collected seeds. Be sure to collect seeds sustainably and only from plants that are abundant enough in the wild. Growing plants from seed can be a rewarding experience that also helps build a stronger connection to your project.
The Planting Process
Planting a Miyawaki forest is a structured yet flexible process, with each step designed to give the trees and plants the best possible start. The dense, multi-layered plantings of the Miyawaki method require careful attention to detail, from site preparation to the final watering. Let’s take a deeper dive into each phase of the planting process.
Site Preparation: Intensive but Necessary
Site preparation for a Miyawaki forest is where much of the work happens, and it sets the foundation for a successful forest. While the technique does require some disturbance to the soil, this is very different from repeated conventional ag tilling, which can harm soil structure and health over time. Instead, Miyawaki forests use a one-time deep working of the soil to break up compacted soil layers, allowing tree roots to grow deep quickly and access the nutrients and moisture they need.
This approach employed in this one-time disturbance is designed specifically to create ideal conditions for your trees to grow quickly and establish themselves. The key here is not mixing the top layers of the soil with the lower layers of the soil in any way. You want to avoid upending the natural soil biology that exists beneath the surface. Instead, the goal is to simply loosen the soil to a depth of at least 12-18 inches, breaking through any compacted layers. This can be done using a broadfork or a tractor implement called a deep ripper.
Once the site is loosened, you’ll also want to add organic compost to the surface and perhaps a bit of fertilizer to ensure that the soil is nutrient-rich. However, be careful not to over-fertilize. The goal is not to push the plants into unnatural growth, but to provide just enough nutrients for them to thrive in their new environment. This process helps mimic the natural conditions of a forest where soil is rich in organic material but not artificially enhanced.
The Planting Process: Step-by-Step

Digging the Holes
When it comes to digging the planting holes, it’s important to create spaces that will support strong root growth. Aim for holes that are slightly wider and slightly deeper than the root ball. The ideal planting depth should result in the root flare of the plant being placed right at ground level. If holes are dug too deep or too wide and then filled back in with loosened soil, the soil around the tree often collapses, which results in trees that tip over or have water pooling around the base. The ideal planting hole is just big enough - no more, no less. -
Planting Densely
One of the signature features of the Miyawaki method is dense planting. For dense plantings, space the largest trees about 2-3 feet apart, and interplant understory herbs and shrubs every 6 to 8 inches. Such a dense planting encourages natural competition, which boosts vertical and horizontal growth. While it may seem counterintuitive to plant everything so close together, this is actually an essential part of the process. Dense planting encourages competition for light, space, and nutrients, mimicking the conditions of natural forest regeneration. It also ensures that your forest grows upwards and fills in quickly.

Mulching and Watering
After planting, make sure to thoroughly mulch and water the entire planting site to cover the soil and settle it in. Watering is especially critical in the early stages, as it helps the plants establish deep root systems. Fertilizing should be done with care—use organic compost or biological fertilizers, but avoid synthetic fertilizers that can harm the local ecosystem. Then cover all of the soil with any kind of organic mulch like leaves, wood chips, or compost. If planting seeds in your Miyawaki forest, take care not to mulch so deeply that your seeds can't germinate through it. Otherwise, lay it on thick: mulch helps retain moisture and suppresses weed growth, slowly fertilizes your plants, and provides habitat for diverse soil organisms.
Tools and Materials for Success
Having the right tools for the job is crucial to ensure the planting process goes smoothly. You’ll need basic tools like a shovel, rake, and broadfork for digging and prepping the site. If you’re working with a large area, consider using a mechanical auger or deep ripper to speed up the hole-digging process. You'll also need protective gear like gloves, hats, and sunblock, especially if you're working with volunteers.
When to Plant
The best times for planting are during the cooler months of spring and fall, when rainfall is more predictable, and temperatures are moderate. This gives plants time to establish their root systems before the heat of summer or the cold of winter. Early spring or late fall are ideal for most temperate climates, while in warmer climates, the rainy season provides an excellent window for planting.
Facilitating Volunteer and Community Participation
Miyawaki forest planting events can be transformative, not only for the ecosystem but for the community. Getting local groups involved in the planting process is one of the most powerful aspects of this method. It fosters a sense of environmental stewardship and creates lasting connections between people and nature.
Organizing Volunteer Events
A successful planting event starts with clear organization. Start by identifying the groups that would be interested in participating. Local schools, environmental organizations, businesses, and community groups are all excellent places to start.
Once you’ve identified your volunteers, make sure to provide clear instructions on what to expect. Whether it's a group of corporate employees or a community gardening club, each participant needs to know what their role will be, and how their efforts fit into the bigger picture. Assign specific tasks—digging, planting, watering, mulching—and make sure everyone is equipped with the tools they need.
Making the Event Educational and Fun
Planting trees is a rewarding experience, but to maximize the impact, you should make the event educational. This means giving participants the opportunity to learn about the Miyawaki method, its benefits, and how they’re contributing to local biodiversity. Provide short talks on forest restoration and the importance of native species, or even bring in guest speakers from local environmental organizations.
Hands-on workshops or demonstrations can also be a great way to engage people in learning more about sustainable forestry practices, planting techniques, and the broader impacts of biodiversity conservation.
Building Local Partnerships
To make your planting event even more successful, consider building partnerships with local stakeholders. This could include businesses, schools, government organizations, or other nonprofits. A strong partnership network will help spread the word about your event and generate more interest in the project.
By partnering with local stakeholders, you can also tap into their resources, whether it’s funding, volunteers, or materials. Plus, having multiple organizations involved can amplify the community impact and build momentum for future projects.
