The average last frost date for our city is April 3, +/- 10 days. We planted our garden on April 25. On April 28 we had heavy rainfalls and on April 29 morning frost. All my tomato plants are dead and most of the pepper plants too. The only survivors are the seeds we planted, they are all coming up well. Unfortunately we have no extra money at the moment, so buying replacement plants is out of the question. Looks like I'll be having a tomato-less Summer (at least as far as homegrown tomatoes go, there is always the farmer's market). Yikes.
Note to self: Don't plant anything before the first weekend in May next year.
