No-dig Method and Nemaslug

[Return2thebasic]

So I sprayed Nemaslug the other day. But the problem is that I'm unsure when I could start using no-dig to create new flower bed after that.

The point of Nemaslug is to allow slugs get exposed to the nematode in the soil. If I cover up the sprayed soil with cardboard and compost, wouldn't that defeat the purpose of Nemaslug?

Do I need to wait for a week or so to allow the nemotode work before starting no-dig? Advice please!

I’d just make up the beds and get cracking, to be honest. I don’t think cardboard and compost is that much of a barrier to microscopic worms. Hopefully there won’t be too many slugs in the compost you’re using. You reapply nematodes every 6 weeks anyway so it won’t be long until you top up the new beds.
