FULL SHADE
PARTIAL SHADE
LIGHT SHADE
or what we consider FULL SUN
If the entire backyard was not bordered by trees the above would be consider by most to be FULL SUN
Briefly Defined Shade
Full sun = 8 plus hours of direct sunlight.
Light Shade = 5 to 7 hours of direct sunlight.
Partial Shade = 2 to 4 hours of direct sunlight.
Full Shade = no direct exposure to the sun,2 to 6 hours of indirect sun light.
Dense Shade = no direct sun all day,very little if any indirect sun light, dappled.
With my experience....
for Full Shade Plants ...
the more hours of indirect sunlight the better !
