They're here!! Today has been a very good day. Not only did I discover that our income tax refund had already been direct deposited to our bank account, but the first order of garden seeds from Pinetree Garden Seeds arrived in the morning mail!
There are so many good reasons for growing your own plants from seed: economic, environmental, greater choice of varieties and colors, preserving heirloom varieties, avoiding GMO veggies, and so on. But aside from all those reasons, there is something just so satisfying about the whole process, and for me, at, least, seeing seeds break the surface and lift their heads to the light is a wonderful and exciting experience!
I like buying seeds from Pinetree because there are fewer seeds in a package, which means less waste and less seeds I have to carry over from year to year and run germination tests on, since I hate to waste seeds. After reading Mel Bartholomew's Square Foot Gardening, I began using his single seed sowing method which made a lot of sense. Sowing just the number of seeds I needed also alleviated the guilt pangs I suffered when thinning out little seedlings that had struggled hard to break free of their seed cases and emerge victorious, only to be rudely plucked from the soil and discarded!
Having already made space in the greenhouse a few days ago, and having disinfected my seed starting containers, I was ready to begin sowing. I use basically the same equipment in the greenhouse that I used before we had the greenhouse: A large black plastic mortar mixing box, heat cables, a fluorescent light, a few plastic flats without drainage holes, and a variety of recycled plastic containers such as yogurt, cheese, margarine tubs and some containers that gourmet dog food came in. I punch drainage holes in the bottom of these and have found that they last very well and can be reused several times.
First we put some sand in the bottom of the mortar mixing box, then bury the heating cables in the sand.
I like to start my seeds in vermiculite rather than a seed starting mix because I've always had good luck with it. The vermiculite moistens easily and it's very easy to extract the seedlings for repotting without damaging their roots. After making sure they all have drainage holes (I use an ice pick to punch the holes), I fill the tubs with the vermiculite, then place them in a plastic flat half-filled with water. Once the vermiculite is evenly moist, I remove the tubs and begin to sow the seeds, using a Popsicle stick marked with the seed name and sowing date, and place them in a dry flat on top of the sand.
I then place a piece of clear rigid plastic, like Plexiglas, over the mortar box and plug in the heating cable. I keep a thermometer inside the mortar box to monitor the temperature, which I try to keep at around 70 degrees Fahrenheit. On sunny days the greenhouse heats up and we don't need to plug in the cables. Even when the outside temperature is in the 20s and 30s, with the sun shining, it sometimes gets so warm that we need to vent or remove the cover. I keep an eye on the moisture so that the containers don't get too dry or too moist, and water the containers by putting water in the flat so the the containers are watered from below. This method seems to help avoid the seeds damping-off. I don't fertilize at this point, since seeds contain all the nutrients they need to germinate, and once the seedlings have developed their first true leaves I prick out and transplant them into individual containers filled with potting soil and begin to fertilize them. So now, all I have to do is wait for that magic moment when I see little crooks of green poking up through the vermiculite, ready to greet the world! At that point, I'll keep the temperature a little cooler and bring on the lights so that they will develop into sturdy little seedlings ready to move into the garden when the soil is warmed by the spring sun.
