April 26 2011: Taking the seedlings out for a walk

Once a week or so, I take my older seedlings out of their watering trays and give them some liquid fertilizer. (Once they get their first set of true leaves, they're ready to start getting fertilizer.) I start them on a very dilute mix (one-quarter of its regular strength) and build them up to full-strength fertilizer by the time they're ready to plant outside. My plants are on about half-strength fertilizer right now. You can see most of my seedlings in this picture -- the only ones that aren't down here are the very new ones which haven't sprouted true leaves yet -- chard, cucumbers, & zucchini, and a couple varieties of flowers. (Oh, and the cauliflower and broccoli are still in the lightbox upstairs.) You can also see the totally decrepit old freezer our house's previous owners left in the basement -- it is too heavy to move up the stairs! HOW DID IT GET DOWN THERE IN THE FIRST PLACE? Theory: the house was built around it.

I guess I could just give them fertilizer in their usual watering trays, but I'm wary of that because I don't want the fertilizer to collect in there -- it stops being dilute if the plants are sitting in it. So instead I take them out and put them on other trays just for today.

This is kind of a big job at this point, so to help make the work worthwhile I'll leave them sitting out for a couple hours with the fan on. I'm not sure if this is just superstition, but I have heard that setting seedlings in the breeze from a fan helps to prevent damping off.

I'm contemplating starting to move some of the seeds outside during the day -- partly to harden them off, but also partly just because I'm running out of space and lights. If it was just a little warmer, I would consider planting some of the tougher plants out. We are still getting night-time temperatures of 0 or a few degrees below, so I think it's almost time to plant out the artichokes, broccoli and cauliflower. In the meantime, I will just have to keep squishing them in, since I'm obviously not going to stop starting new plants -- that's a little too logical.
