Miyawaki Method
Identify a site. Partner with landowners: schools, cities, churches, or private land owners to plant a mini forest!
Prepare the soil well. Dig to at least 12 inches. Hand tools or machinery can be used to aerate the soil.
Add compost and mix together with the existing soil. In the end the soil should be so soft that you can scoop it with your hands!
Size of plot determines number of plants.
This plot is about 300 square meters.
Plant 3 seedlings per 1 square meter.
300 × 3 =900 plants

Based on the Miyawaki method density of 3 seedlings per m². Results are rounded to the nearest whole seedling.
Dig a hole as deep as the pot so that the plant will be buried at the same soil level as in the pot.
Hold the pot underwater until bubbles stop emerging from the pot.
Gently return the soil into the hole and around the plant. Don't push down on the soil. Soft, porous soil facilitates rapid root growth.
Cover planted area with 3 inches of mulch and then water thoroughly .
