Hi i d leave that area as an access trail for painting etc and either move plants or plant outside the eave perimeter.
Planting under roof overhangs in shaed.
One thing i didn t consider how dry it is under the roof overhangs.
Deciduous plants allow winter sun through their bare branches and exclude summer sun with their leaves.
A building or fence that blocks the wind may affect the rain direction in windy storms.
At my house in the sandhills the roof overhang is about the only place that gets enough water to keep the above plants alive.
Rain snow and ice will damage any plant in.
But i don t think i have as much shade as it looks like you have.
You could fill the area with river rock mulch bricks etc.
Planting directly under the drip line is asking for trouble.
Rain snow and ice will damage any plant in that location sometimes terminally.
Note too that water cascading off a roof can damage plants below.
In addition to providing shade plants can assist cooling by transpiration.
A roof overhang can create a band of dry shade near the house.
It s going to remain as natural and rustic as practicable using native plants where they make sense.
By moving out from under the overhang there will be much less maintenance work and the plants will love it.
Fixes for dry shady plantings.
Notice how the trees and shrubs in this foundation planting are placed beyond the drip line of the overhanging eaves.
I don t have much use for them but maybe aspidistra cast iron plant.
They are 24 plus gutters so about 30 deep.
Tolerating dry shade is not the same as thriving in it.
Planting under evergreens is tough because there s little light and plants have to compete with roots for.
Dry shade can even be found under plants.
When planting under trees keep in mind that tree roots suck up much of the available water and give a fair amount of shade once the leaves fill in.
I ve noticed how dry it is under the eaves now that the gutters are up.
Design the back layer with plants tolerant of full shade.
Plants also enhance the visual environment and create pleasant filtered light see landscaping and garden design.
Blocked shade is when a building roof overhang wall or fence keeps out sunlight.
You could try them they all tolerate a lot of shade.
Even if other areas under the overhang receive partial sun for a few hours per day the back row is unlikely to get a significant.
