Looks like leaf blight not leaf spot...not that it really matters. lol Pick off the bad leaves and burn them or replace the plants if they are sending new ones. Get some mulch under the plants to reduce rain splash.
If I had a tomato that was REALLY important to me and i couldn't pick up more seeds someplace esily I too would move a couple waaaaay over there to protect them! :)
I means it COULD happen. I asked our county extension agent about this at class last week and he said that the chances are slim that they will cross because of the way tomatoes pollinate.
I try to never let my small seedlings dry out. They need to be kept at least damp when they are first starting out. It also sounds like you may be over fertilizing. Most seedlings that are started in a starting mix need NO fertilizer until they are much bigger.
It snowed off and on all day here and sometimes really really hard but almost none really stuck. The ground was fairly warm and wet.
It's supposed to get up to almost 50 tomorrow. I hope it hurries and does it EARLY. We are taking our GD to a memorial service to mark the anniversary of the wreck...
I have Virginia Creeper that Mother Nature planted on my chain link fence. It runs about 50 feet down one side and I have to beat it back from the gate to keep it open. lol Last year the Japanese beetles chewed it to pieces but that kept them out of my garden. :)
