Number of trusses?

Scarlet, do you grow tomatoes in the same border every year? Currently we grow out greenhouse tomatoes in pots, with the borders being pebbles over weed membrane instead of soil, but I would like to grow in the ground next year for a few reasons. Just slightly concerned about the potential of disease.

I've been growing toms in both GH border soil for decades.  Every couple or three years I dig out, say, 8" or more soil and replace with sieved veg patch soil.  Only one year had disease problem but that was a fungus due to poor ventilation not the soil.  Mind you it's only an 8x6 GH so it's not that much work to change the soil, anything bigger could be a chore.
