What this site documents
The Miyawaki method was developed by Japanese botanist Akira Miyawaki as a way to restore native forest communities on degraded land by planting a dense, multi-layered mix of indigenous species. Over the past decade, municipalities and civic groups across Europe have adapted the technique for tight urban plots — parks, schoolyards, roadsides, and post-industrial strips.
This site covers the practical aspects of running such plantings in Poland's temperate continental climate: which native species are suitable, how planting density affects early competition, and what maintenance looks like through the establishment phase.
- Planting density Typically 3–9 plants per square metre, combining canopy, sub-canopy, shrub, and groundcover species in one go.
- Minimum plot size Effective results reported on plots as small as 50 m², though 200 m² or more provides better species diversity.
- Maintenance window Active weeding and occasional watering in years one and two; self-sustaining growth typically established by year three.
- Soil preparation Biomass amendment — wood chip mulch, compost, and sometimes mycorrhizal inoculant — before planting to improve structure and water retention.
