Pretty much. I think crop rotation is a bit overstated personally. If I find a spot that a particular veg. grows well in, why would I not keep growing it there. If you’ve got healthy soil and don’t introduce infected soil, all should be good, though some diseases can blow in with the wind, but here, where I am, due to geography, it’s not known to be an issue.

Some plants can build up bugs like nematodes in the soil if continually cropped in the same spot. However, that can be managed, either by planting companion plants that repel the pest, or growing a crop that inhibits it in the off season. I don’t go overboard on this type of thing, but it can be helpful in some cases.

With potatoes, the issue is spreading the disease - I’m not intending to sell or give-away potatoes as seed, so that’s not a problem. I’m more likely to bring in disease if I buy in seed potatoes, but certified seed potato should be okay.
