Seedling Update

So we are a little over two weeks since our last post, and I was mentioning that I would need to re-pot the Aerogarden soon, because the seedlings were outgrowing the current situation.   The post was on a Thursday, and I did, indeed transplant about half of the seedlings into larger pots that weekend.  These went out under the 4-tube fluorescent fixtures in the garage.

This included all of the Bok Choi, Some Arugula, and two Swiss Chard.  I planted the plugs into a larger plastic garden pot, using generic potting soil.  When I opened the Aerogarden, the roots had grown together into a thick matted tangle, which I had to separate out with careful fingers.  Roots were snapped along the way, and I had to coil some around the pot to make them all fit.  This suggests to me that I probably should have re-potted sooner.

I didn't loose any of them, though, and they all seemed to like the new light, on an 18-hour cycle.  I also gave them a weak feeding of miracle-gro.  After two weeks in the larger pots, they became as you see them above, still rather compact, but pressing on the lights.

Emboldened by their eagerness, I took a small sample of 4 Arugula and 2 Chard and planted them in my outside garden, after a couple of days of hardening.  The garage is not heated, so they hadn't been in a climate controlled area for many days, and I still have the low tunnels up to enhance the microclimate So we'll see how they do.

This is what they look like in the raised bed.

The Arugula above is definitely looking a little ragged and I'm hoping a bit of space will help them even out.  The spatulate leaves seem to be yellowing, but new leaves are showing in the interior that are deeply lobed in the Rocket style, and are a much nicer shade of deep green.

The chard, to the right, is in beautiful shape. With a rich red color on the stems and veins.

Both of these had roots throughout the pot, growing out the bottom and up the sides, so two weeks seemed to be plenty to get them ready for outdoors.

These were seeds that I planted in the Aerogarden on March 4th.  It's about 5 weeks later and they are ready for transplanting into the garden.  My calendar for their progress looks like this:

• Week 1: planted seeds into aerogarden plugs.  By the end of the first week, all the bok choi, arugula and chard had germinated.  One week for germination
• Week 2-3: weeks two and three, the seedlings grew well.  Water and nutrients were cycled and light was on a 24 hour cycle
• Week 4: In the middle of this week, I transplanted the Bok Choi, Chard and Arugula into small pots.  2.5 weeks in the Aerogarden as seedlings.
• Week 5: Grew for 1.5 weeks in transplant pots under fluorescent lights.  At the end of this week, I transplanted into the garden the first half of the re-potted seedlings.
• Week 6: This is the transplant's first week in the raised beds.  I still have all the bok choi in pots for one more week, giving them the full 6 week start cycle.

That gives me about 6 weeks from planting seed to transplanting into the raised bed.  And these are for simple plants.  It is likely that other plants (like tomatoes and peppers) take longer to germinate and require a longer growing out period before they are ready for the garden.

So that means that if I want to plant tomatoes and peppers in the first week in June, I need lead time of at least 6 weeks to prepare seedlings.  If that's true, I should be preparing to seed peppers and tomatoes soon.
