That is too bad!! I'm so sorry!

I have read here at gardenweb that sometimes saving heirloom seeds from the same genetic line over and over can eventually cause weakened/sterile seeds. Hopefully someone with firsthand experience can tell you more.

You may want to try posting in the growing tomatoes forum. That forum is very active, and you may get a faster response there.

In the meantime, whatever the reason, if you've waited a week or so and you've got no sprouts, I would order new seeds. There are lots of online retailers, including ebay, and I would be happy to point you to some of the ones I like if you're nervous about online ordering.

Sorry-- I would be heartbroken too :-(

Oops-- nevermind-- they were saying inbreeding weakness happens with corn, but not with tomatoes.

Jessica - thanks for responding. I hadn't heard of tomatoes weakening, but seriously, anything is possible. Thanks for pointing me to the tomato forum - I guess I should have posted there first, then I read the note about not posting the same thing to multiple boards & just went with heirlooms!

I do appreciate your kind words - we will probably just buy new plants at this point. Isn't this weather amazing?? I can't remember it this hot for this many days in April! Hopefully, we will have a good growing summer with enough rain water falling for our plants!
