Avoid weeds on excavated areas

How large is the property or the area to be filled? Depending on the size, a few cubic meters will add up at a 30 cm fill height. Do you really want to wheelbarrow it later or should you better have the topsoil delivered now?

So behind the house it’s about 200 to 300 sqm, we are also going back and forth thinking about it. A truck can reverse in nicely but not all the way into the back corner because it cannot swing out. Also, the financial aspect plays a role, which is why everything has to happen gradually.

When do you mow everything down and can we then leave the mown material lying there and just put the topsoil over it?

Mow, leave it lying and work it in, so mix it. It all decomposes. At least that was the case for us.

Absences, leaving it lying and underworking, so mixing. It all decomposes. At least that was the case with us.

And when do you mow it? After winter?

No, they are not winter-hardy. It’s all stated on the package. For us, it was so long ago that I don’t remember. You can also do several in a row, so now and then in spring next year.

Great. Thanks a lot anyway for all the tips and ideas

You can use yellow mustard.
Sow
Keep moist until it has germinated
Mow a few days after flowering. If it does not flower, let it die off when frost does its work and work it in next year
