Can you plant tomatoes in the same spot for more than 1 season?

Not in the same compost in a pot, that's for sure! If in the soil outside, just dig and refertilise. Otherwise, fine!

I wouldn't recommend it - they might be Ok for a couple of years, but I've had problems with 'bottom end rot', which is caused by an innappropriate balance of nutrients in the soil, caused in my case by growing them in the same place for too long, even tho I fed them and improved the ground each year.

The general recommendation for all vegetable crops is to rotate them to avoid the build-up of pests by growing them in the same place year after year. I have four small beds which are rotated - peas and beans, brassicas, carrots and leeks, and tomatoes

we grow all our toms in pots in the greenhouse, just sterilise pots before required and also use new compost.you could also do this outside
