I don't know about potatoes, but a solution for tomatoes is to plant them earlier. Use a protected area or sun room to start them and put them out as early as possible. I've already got cherry tomatoes about grape-size. Another tip is to rotate plants so you never use the same soil for the same kind of plant two years in a row.OK, maybe you can tell me what to do about late blight on my tomatoes and potatoes? ...
To keep this pool related: It snowed in Edison during the recent Make It Happen event (April 15th or so), and I hope people didn't already have their early tomatoes out.
