I ended up leaving the plastic down for over seven weeks.

And now, another week later, it is being colonised by nasturtium.
Which for now is all right. It's easier to get rid of than most other weeds.
Overseas you'll probably be surprised to read that even nasturtium is a weed here. We have a saying here, anything you stick into the ground will not only grow, it will flourish.
From now on until spring in September, this are will be in shade and therefore probably not much use trying to grow any shrubs.
I want eventually to grow native sennas there, to encourage the white and the yellow migrant (two distinct species) butterflies.
