I'm starting seeds several months early this year and, yet, I'm already late! According to my favorite planting calendar, I'm a week or so late in starting my onion seeds. To be fair, I had every intention of starting them last week but USAir cancelled my flight home (oh the joys of being in the airport for 8 hours with an infant!) from Florida and I arrived home too late to start the process.
To revisit how to start your own seeds, here's a concise overview of the process (more details & photos are in my previous post on the subject):
1. Sanitize pots/yogurt cups/whatever in a 9:1 water/bleach solution. This keeps any nastiness away from your impending babies.
2. Wet potting mix & put it in pot/yogurt cup/whatever. Don't use dirt from your yard.
3. Plant seed at depth listed on the package.
4. (Optional) Sprinkle milled spaghnum moss over top. This, along with adequate air circulation, prevents damping off. I've also heard that cinnamon has some anti-fungal properties so you could try that.
5. Keep the soil moist & wait.
I started onions, kale, two types of kohlrabi and some cilantro. I'm probably early for everything except the onions, but my kale and kohlrabi grew so slowly under the grow lights last year that I decided to give them more of a head start. Overall, I filled an entire flat with just these 4 crops! And, I plan to start another round of onions in a few weeks. I've only got 2 grow lights so it will be interesting to see if I can make my ambitious plans happen.
