The raised beds against the pale wall

Before you buy a pergola, move the table.

Every change below is put into the plan and the whole model is run again. That is why a pergola's winter cost shows up here without anybody having written it down, and why the cheapest thing that works is allowed to win.

Where it stands now

Something growing here

In the bed works for growing things across a day like this.

Usable light is inside what this use needs: 34.3 mol/m2/day against at least 6 mol/m2/day.
Hours of direct sun is inside what this use needs: 12.3h against at least 1.5h.
How long it stays wet is inside what this use needs: 7h against at most 10h.

Confidence medium (60%). Enough to point in a direction, not enough to buy against.

What this answer was built from

Use: Something growing here
Place: In the bed
Weather: High desert, cold winters, intense sun (scenario shape) (from a published source)
Method: A whole day in September, traced against the scene rather than read at one hour

Something growing here is read across a whole day or year rather than at one hour, so single changes are compared on the questions pages instead. Go there.
