Trying to get my head around crop rotation.

It’s not traditionally used for pots I don’t think but I just can’t face the physical job of emptying and sterilising all the soil and pots or buying more potting mix after the tomatoes and zucchini are spent. (They got hit by black spot and powdery mildew despite the spraying.)

I’m willing to pull out and dispose of the spent diseased plants afterwards and maybe dig in some manure but am trying to avoid the physical labour of emptying the pots and thought of treating them more like a garden bed.

Maybe I’ll try just chucking a different fungal resistant plant in there afterwards. Perhaps it might be ok if I choose resistant hybrids. Beans and peas are recommended after tomatoes and zucchini to restore nitrogen but also get fungal diseases so I don’t know.

I could just be lazy and do a manure crop over autumn or winter.
