ᐅ Preventing weed growth on excavated areas

Hello everyone.
We are currently planning our outdoor area and are doing as much as possible ourselves.
We have already had the future lawn area excavated, since large trucks cannot easily access the site after the terrace and other surfaces are installed. Early next year, we plan to fill the area with 20 to 30cm (8 to 12 inches) of topsoil once all the paving and other surfaces are completed.

Now we have a serious problem with weeds, especially thistles, and I have been considering covering the excavated area. The question is: Is this effective, and can it help control the weeds well? Would it be better to use an opaque landscaping fabric or a tarp for this purpose?

Thank you very much and best regards 🙂

How large is the plot or the area to be filled?
Depending on the size, filling to a height of 30 cm (12 inches) can add up to several cubic meters.
Do you really want to wheelbarrow that later, or would it be better to have topsoil delivered now?

At the back of the house, it's about 200 to 300 square meters (2,150 to 3,230 square feet). We're still debating back and forth. A truck can easily reverse in but can’t reach the far corner because it can’t maneuver around.
The financial aspect also plays a role, so everything has to happen gradually.

When do you mow everything down, and can we just leave the mowed material on site and cover it with topsoil?

Cutting down, leaving it in place, and mixing it in—that is, working it into the soil. It all decomposes. That was definitely our experience.

Leveling off, leaving it and mixing it in underneath. It all breaks down eventually. That was the case for us, at least.

And when do you cut it? After winter?

No, they are not frost-resistant. It’s all stated on the packaging. It’s been too long for me to remember exactly. You can also do several cuts in a row, so now and then again in spring next year.

Great. Thanks so much anyway for all the tips and ideas.

You can use yellow mustard.
Sow the seeds.
Keep moist until germination occurs.
Mow a few days after flowering. If it does not flower, let it die off when frost sets in, and work it into the soil next year.
