I’ve never tried and yet to find anyone that has purposefully tried in the past.Late autumn being November, winter Dec to Feb, if you can sow plants after WW and have them producing seeds by November then that's good going. I think it's just possible following Winter Barley.
There’s a few people saying they drilled an AB9 mix late and it never seeded but they used a completely different seed mix to what I intend to use…
Theres a few people that say they killed off mustard/radish cover crops early because they thought they were going to set seed but they didn’t wait and find out…
There’s just as many advisors that suggest it might work as say it won’t work.
None of the scheme is backed by any real world trials data the whole ethos as I see it is “have a go and see what happens”
Ask me again in December and i’ll let you know if I achieved it …
