I've been thinking about planting my onion plants in black mulch next season although we harvested a fair crop of bulb onions yesterday the onions are having to complete with weeds
I've tried this method before with little succus but that was planting through thick black plastic sheeting but as the black mulch is much thinner it maybe better for planting and I made the holes in the plastic sheeting to big and as sets just didn't come through the plastic and weeds emerged instead of onions so I ended up removing the plastic sheeting as a bad job for the sets to grow
so a smaller cut in the mulch so it could be better what I'm not sure about is as onion plants when the onion plant grows will the bulb it produces grow through the mulch or under the mulch?
I've looked for some info on youtube about planting in black mulch but its a bit vague and doesn't really explain to much its more for the commercial grower so any info on this topic would be much appreciated as i would really like to try growing onions in black mulch as well as my brassicas and if it works its going to save quite a lot of work removing nets of the brassicas
