We are planting heirloom varieties this year and are planning three
different types of tomatoes (beefsteak, roma and one other). Our
garden plot is small and even if we plant them all as far away from
each other as possible I would say there will be less than 4 feet
between varieties.

Will these three plants "interpolinate" creating a non-standard variety
from the seeds next season? Hubby seems to think this is inevitable
since the plants are so near to each other.

Has anyone had any experience with this happening?

Thanks.
