On January 16 I started my first flats seeds for the 2011 edible gardening season. I started half a flat of each ‘Red Burgundy’ and ‘Borettana Cipollini’ onions. Onions like warm soil, so I put it on the 10″ x 20″ seedling heating mat my mom lent me. I covered the flat with a clear dome to keep in the warmth and the moisture and waiting, checking on them every day of course.
When I checked them in the morning on January 21 and I had germination! That’s pretty quick for onion seeds, they always seem to take a little extra time. Of course there were only a dozen or so tiny shoots on that day. Seeing those first little green shoots of the seed starting season is always an exciting thing!
Yesterday every soil block in the flat had at least one little green shoot and most of them had three. Looks like these onions will be ready to plant out in the garden come March. I can’t wait!
I also have other onions in the basement planted only 2 days later, but since they’re not on a heating mat they haven’t germinated yet. I ordered a 48″ x 20″ heating mat which will have enough room for four flats. I’m hoping it arrives soon so I can start 4 more flats of onions. If you’re planning on starting a lot of vegetables that like warm soil as onions, eggplant, peppers and tomatoes, a heating mat is definitely a good investment. Especially if you happen to have your seeds starting area in a 55 degree basement like I do. At least it’s the perfect temp down there for spinach and lettuce seedlings, which I take full advantage of mid-summer when starting my fall greens.
