Self seeders and mulch

I'm new to Permaculture and up to now I have used the lasagna/sheet mulching method in my kitchen garden with much success. However, I am planning now to grow self seeding plants, like Egyptian onions, marygolds, lettuce and so on. My question is, will the mulch prevent these from self seeding? How do you guys solve this in your gardens?

My mulch consists in a sheet of cardboard, with soil/manure/compost on top, then a thick layer of straw as it breaks form the bale (ie, still compressed). I am invaded by grass and perennial weeds but nothing grows with these barriers. In fall, I add similar layers on top of these, let rest all winter, plant in spring (slicing the cardboard open if needed).

The quality of soil has improved enormously with this method and I never have to weed , but how about the self-seeders??

Thanks,

Understand there is going to be a randomness to the process and you take
what you get. I try to encourage re-seeding by shaking out seeds where I want
them. Sometimes I pull back the mulch, shake out the seed and then lightly
Re-apply the mulch. The true volunteer plants are still going to happen when and
and where they want to come up. Yes they do come up in and through the mulch.

Thanks, Alex. I'll encourage the self-seeders and maybe I'll reserve an unmulched area for them, too.

does comfrey self seed readily?

Hi Tim,

true comfrey (officinalis) does, but the blocking varieties don't.
