yes, tomatoes are a tropical vine....they only behave as annuals in gardens because it gets too cold for them. But in tropical and subtropical environments, when protected from frost, they will keep growing year after year. If you give them enough soil (like more than 5 gallons), and you let them grow by letting them crawl around your bulwarks for instance, their size will buffer some of the problems they might encounter, but you want to keep the soil as salt
free as possible. If you do end up soaking them in salt
, once the encounter is over really soak the beeguz out of them with fresh water
....Let it run through the soil and take the salt away out the bottom.
