Anytime I get cabbage worms I've always used BT, and you could use sevin dust as well, considering bees don't really pollinate cabbage unless it's flowering. I don't have the experience with the salt or the flour though, so I can't comment on that. ON that note, many don't like sevin, which is okay. Do what you feel is best, but I'm not against it if used with respect. For example, I don't use liquid sevin or any liquid pesticide harmful to wildlife or the environment, as it's not easy to control. Dust on the other hand can be spread on at night and then washed off the next morning. I take care not to get it on flower blossoms. Of course, I only do this on certain plants to avoid harming bees which pollinate others. BUT not everyone is okay with that. BT is a good harmless pesticide as well, considered organic if you're an organic gardener. Some people, like my grandma, spray liquid sevin, not following the recommended dose, on their crops EVERY day to get rid of bugs and the such. I don't agree with this!! lol

I don't know about the sauerkraut. I always follow by taste for mine. I start with a tsp. of salt or so per head, and work my way up until the raw cabbage tastes plenty salty enough for me after kneading it. If the cabbage itself needs more salt because it's bland, I add more. If it's WAY too salty, I don't add any more. When I've measured in the past, I've always used Kosher pickling/canning salt. I think it was 1 tablespoon per 4 cups cabbage.

Cabbage is awesome. So many ways to make sauerkraut. I love it. If we have it, it's a bit of a staple for me. Have you ever tried it in an omelet?

I use broccoli in scrambled eggs sometimes. This morning I had asparagus in scrambled eggs. In omelets I usually use sweet red and orange/yellow peppers, onion, mushrooms. Have never used cabbage in either, but I've used it in chicken-fried rice and that's really good. Today for lunch I had a fat cauliflower steak browned in bacon with a big squirt of fresh lemon on the plate. Mmmmm! I love cabbage just sauteed in real butter with salt and pepper. Maybe a little vinegar. I have a recipe that I got at The Brick Haus in the Amana colonies for sauerkraut salad that I enjoy, but I cut the sugar back by half. Oh, if you've never been to the Amana colonies near What Cheer, IA, you should go. Go for the huge flea mkt in What Cheer and then go to The Brick Haus in Amana for lunch. BE HUNGRY. I see online that those places / events are all still there, but it's been ages since we went.

Sometimes I will use Sevin dust, I had to, last summer, or I would've lost my squash. It put up a good fight but then so did I, out there diligently every morning, killing off adult squash bugs and scraping those little round red eggs off the leaves, laid so carefully in neat rows, seemed almost a shame they were so pretty. But right into a container of water they went, and after I was finished, all the water was flushed into the septic tank. Like you, I don't like to endanger the bees and butterflies. Or myself, actually. I have used BT before. I don't really like to use anything like that if I don't have to but seems like I have to use something or I don't get a crop at all. Japanese beetles move in about July and late August, it's the grasshoppers. My garden just can't catch a break. I've been doing everything I can to attract the beneficial insects, including the predatory ones, and am seeing progress.

My parents did a lot of questionable stuff, like you say your grandparents do with Sevin. Mom thought hybrids were the best thing since sliced bread and never saved the seed of anything except for some little "squash" someone gave her seed for (might've been luffa, picked young, it made star-shaped pieces when sliced. She made a lot of stir-fry with those in it), and that's only because she didn't know exactly what it was or where she could order more seed for it. Everything else, bought new every year after studying the Burpee catalog for several days on end. She spread a lot of Sevin around and some other things, too. She didn't like butterflies, said they were "worms with wings" and also birds were "rats with wings". But you had to know my mother to see how classic those attitudes were for her. ; }
