I am trying to sprout seeds for my garden this year and having a lot of difficulty! For the past two seasons I lived in Denver and had no trouble growing healthy plants from seedlings indoor. This season, I am in a new house in Sacramento, California, and nothing seems to germinate.
I have two trays of a variety of vegetables. The seeds were planted in seed starter soil. I have two grow lights above the seeds on a timer. Most of the seeds have not sprouted. My Zinnia did sprout 3 days ago, only to have keeled over and wilted today.
I am not sure what variable is causing the seeds to stay dormant, or die as soon as they start to germinate.
I have never needed a heating mat in the past, but wondering if temperature may be the missing piece of the puzzle?
Any suggestions are welcome!
