Not sure where to post this, so here goes. We have a down-slope that needs clearing. Most of the weeds are dead (sorry, we have to use RoundUp around here). Several considerations:
We need erosion control.
It's expensive and difficult to dispose of the weeds.
It's a south facing and difficult slope to grow anything on, so we're going at this deliberately, no matter how long it takes.
Our idea was to remove the weeds and cover with black plastic, then start planting in the fall. We will be planting CA natives, so no amendments will be added to the soil. With the heat the slope gets, it should kill any weed seed, at least in the top layer, right?
So, now I'm wondering if leaving the weeds that are there is a viable option. That way we don't tear up the soil removing them and we don't have the disposal problem.
Question: When we go to plant, what will be left? Do the weeds break down under the plastic, or are we going to be faced with a mess to clean up anyway? Never having done this solarizing method before, I'm wondering.
Thanks for any input.
