There are some solid arguments against rotation in here, and I'm starting to wonder if its benefits are over-rated. It would definitely be simpler not to rotate. Each time I set up a new trellis, I know I will have to move it by the end of the season, which is a drag. Knowing I have to rotate influences the sturdiness of each trellis, too. If I have to dismantle it anyway, why should I take my time over its construction?
Additionally, there are some crops I'd rather not grow in my front garden. I would think, I'm not certain, though, that my pumpkins and watermelons will prove garden-lifter magnets, and my two old dogs sleep through many a slow-passing car these days.
Furthermore, my very best tomato bed, the one in which I can grow the most extraordinary peppers and tomatoes, has only been used twice now for its best crops. There's something definitely odd about that bed. That's the bed that made me decide I needed to test my soil. There's nothing I can't grow there, so it always seems a waste to squander it on cucurbits and legumes.
I wouldn't be restricted on what I could plant in my small garden, either. It's not that I don't like cucurbits and legumes; it's that I like solanaceum better. Even though I'm getting a huge kick out of my watermelon and pumpkins this year, it would be nice if I could ditch cucumbers and squash forever. I like peas, but I really don't like eating beans. More importantly, I like
corn, but I haven't grown it in years. It doesn't really fit in my rotation. Even grown with beans, growing corn is like taking nitrogen right out of the mouths of my tomato plants
As for the diseases, by using municipal compost last year, I actually incorporated (apparently) first blight and bacterial speck into all
my beds, so I've been struggling with the issue of tomato-rotation, anyway. Disease? Got it anyway, despite rotation.
As for pests, we don't get that many up here, not like I hear everyone else reporting; they have to be able to over-winter in below-zero temperatues, which many of them can't handle. There was talk last year that this would be a killer grasshopper year, but I've seen killer grasshopper years in the past, years when all you had to do was walk across the yard to raise a cloud, and we're not having one of those years here, probably because of the frigid October we had last year.
I'd like to hear more from people who don't rotate. If I didn't have to rotate next year, I know just what I would put in each bed, and I'd definitely put in more tomatoes and peppers than I do now. Oh. I'd grow corn, too!
