Water the plant in its pot and set it aside. Dig a hole
three times the width of the pot and twice the depth of the soil
in the pot. In a pile to the side, mix that soil with 10%
to 20% Amend mulch or equivalent.
Refill the planting hole to about one inch above the bottom of
the pot with the mulched soil.
Tamp the area where the plant will sit down one inch where the
top of the plant's soil will be even with the top of the ground.
This will prevent the plant from sinking and resulting in trunk
rot which may kill the plant.
Remove the plant from its pot and gently loosen any bound roots
with a fork. Place the plant in the ground and check to be
sure that the top of the plant's soil is level with the top of
Refill the hole with the remaining mulched soil, tamping it down
as you go, until the soil in the hole is level with the ground.
Build a berm around the plant approximately the size of the
outer border of the hole. Water the plant twice. You
have now successfully planted your native plant. (Just
a note: This is also the best way to plant all plants
except that non-native plants prefer 50% mulch in their planting soil)
