Tomato question

Hi. I'm planning to grow some tomato plants outdoors on the plot this year as well as in the greenhouse. The thing I'm confused about is the area of ground I'm going to use had potatoes in last year and some stragglers I missed have sprouted. Am I safe to use that ground for toms once I've dug it over and pulled all the sprouted potatoes out or should I use another space? Thanks.

As tomatoes are rather prone to a variety of troubles, I would definitely plant elsewhere.

It's generally good to rotate crops so that you do not grow plants of the same type in the same bed in the following year.  So ideally, I would put the tomatoes somewhere else.   However it often gets difficult to follow this advice to the letter, especially if you have a small plot and need to juggle things to fit them in. 

Unless you had blight problems with your spuds last year I don't think your tomatoes would come to much harm due to an unwanted volunteer potato in the same bed.
