ᐅ Weeds on stockpiled topsoil

Hello!

Our stockpiled topsoil is completely overgrown with weeds. Currently, we are considering how to proceed. The topsoil is planned to be spread across the plot in October, and the garden will be prepared next spring. Should we start removing the weeds now or use herbicides?

We have a similar problem. The soil has been spread out on our property for a year now, but due to various construction activities, no grass has been sown yet.

As a result, weeds are happily growing around. We plan to deal with them thoroughly by autumn and then sow the lawn.

You should at least prevent the weeds from growing so large that they can reseed themselves. That means at minimum cutting them back—pulling them out completely is better.

Also, keep in mind that roots can regrow once they are in the soil, sometimes even if only root fragments remain (for example, with thistles). The only solution here is to remove the roots as well. By the way, I haven’t had good experiences with hand weeders for this. @T21150 had very positive results with the Fiskars weed remover (advertisement: stab, click, pull out). My primary tool for working the soil is a digging fork.

We also use a weed puller, but you should be aware that it leaves holes in the lawn. I wouldn’t pull weeds without reseeding the lawn afterward. Personally, I find that too time-consuming.

If you plan to sow seeds in spring, it is enough to dig or till the soil when there is a light frost. The frost will then kill the weeds.

This way, the sowing can be done initially without troublesome weeds, although they will of course return very quickly.

Only then does the real battle against dandelions, horsetail, and other weeds begin.

If sowing is planned only for spring, digging or tilling the soil during light frost is sufficient. The weeds will then die off in the frost.

Be careful – it really depends on the type of weeds.
If the weed growth is small and fine, then your statement is correct.

For typical deep-rooted weeds, digging and some frost don’t really help.
It always depends on the weed growth. How large and strong the plants are.

Last year, we already removed huge amounts of poppies, thistles, dandelions, wild chamomile (which is not deep-rooted), etc. We also dug the soil again because lawn seeding was actually planned for this spring. Nevertheless, this year we had our usual favorites returning, happily growing both upwards and downwards.
