I have been gardening vegetables for decades. No till, heavy mulch, even composting and swills and teas. But again this year my efforts were mostly consumed by cabbage butterflies and flea beetles. Yes, I've used many hoses and tents of mesh. Yes I've rinsed with the hose. No I will not spray with chemicals. I have used neem though.
I'm in zone 3b. Studying regenerative farming. The belief that if I get the soil right the pests will leave my plants alone leaves me scratching my head and continuing to search for the holy grail of soil health.
Currently thinking: trace minerals and looking at Steve Solomon. I understand (especially on our 100+ year old family farm) that agricultural chemicals of the past have rendered zinc inert or so I am told. Also get that some say the minerals are all still there, we need only the bacterial and fungal friends to deliver them.
Anyone get the brassica soil formula right? I wanna learn.
