Hi Steve that is spooky! I have a solar tunnel if you want to ask anything about them – will try and help.
I don’t see why you can’t use no-dig for growing flowers – although if you want self-seeding annuals you’ll have to be a lot less efficient with the hoe in case you take out all the things you’d want to keep. You would probably have to consider hand weeding beds instead and get good at recognising flowers vs weeds at a small stage. Beds of perennials aren’t usually dug anyway.
