Well, it was time.
The yellow celery (Golden Boy celery) had outgrown their tray. They needed potting up.
The question was, how to do that without damaging their roots?
That’s the down side of scatter sowing such tiny seeds. Especially when the germination rate was so high!
I decided the best way to do it was to set them into a seed snail roll.
As with the onions, I wanted to use potting soil rather than a soilless seed starting mix. That meant, more sifting. Which had its own challenge. Wearing a dust mask again was out of the question. I just can’t wear a mask anymore, and trying to last time was really awful. Yet not having some sort of protection was also out of the question because of how much dust sifting the dry potting soil would raise up.
My solution turned out to be pretty simple. The clear plastic garbage bag I use to protect my work surface is large enough to cover the entire bucket, and have enough slack that I could grip the handles of the colander I am using as a sifter and shake it. Yes, small amounts of dust did come out from below, but this was at floor level and it wasn’t an issue.
Before I started, I emptied the old, cracked tray I was using to collect the big pieces. This is what I got.
The depth of the soil barely reached my second knuckles. Meanwhile, just look at all those pieces that got sifted out! Totally insane. This bag was purchased last year, and I’ve heard that a lot of people were having the same issue. A few sticks is pretty normal, but nothing to this extent. It wasn’t even just one brand, either. Hopefully, the companies have gotten better at making sure their raw material is properly composted before bagging it up and sending it out!
That done, it was time to prepare the seedlings.
The first picture is the “before” shot. You can see how dense they are. The tray is bottom watered, and roots are showing out the opening. Roots that would be quite entangled. How to get the seedlings out and apart, then transplanted, gently?
In the second picture, you can see what I decided to do. I had a tray (a thoroughly cleaned and repurposed meat tray that we’ve had for a few years now) that was wider and flat. I carefully moved the whole clump over into the tray, then very gently started to loosen the seed starting mix to untangle and free up the roots a bit.
Then I got some hot water and thoroughly moistened the sifted soil. The seed starting mix the seedlings was in was really quite cold. Not good! I wanted to transplant them into soil that was at least a bit on the warm side.
I had prepared a strip of packing material – this time, using a clear repair tape I happen to have, instead of painters tape, to join three sections to make one long strip. I started out by laying a thin layer of soil over about 3/4 of the strip, as I wasn’t sure just how much of it I would need to use. Then it was time to VERY carefully and gently pull apart and set out the seedlings.
I was able to get all of them in, and did add more soil to the roll to fit them all.
The remaining seed starting mix got added to the bucket of sifted soil. I added more hot water and mixed it all up before adding another layer of soil to the roll; just enough to cover the roots.
Before rolling it, I added strips of masking tape to the end, so it just needed to be lifted into place, with the tape already handy to close up the roll.
With the two layers of soil in there, the result was a pretty thick roll. I could use the plastic underneath to hold the soil in at the bottom, but there wasn’t much that could be done at the top, and soil was falling out. Once it was taped closed and the roll set upright, I found a few seedlings had fallen out with the soil. I found some gaps and carefully set them back in. I then used some of the soil that fell out to fill in the top of the roll and support some of the seedlings that seemed to need it more.
Now, it’s back in the tray under the shop light. Both trays were empty of water, so I added warm water to the trays to maintain bottom watering.
While I was doing all this, I had the heater going. It’s aimed under the shelf I have the trays on. The thermometer is kept at the far end, and the temperature was only about 13C/55F. Holding my hand under the shelf, though, I could feel it was a lot warmer just under the trays. So I set up the thermometer next to the tray with the snail roll, which is at the far end from where the heater is.
The first picture shows the “potted up” celery back in their tray. After setting up and leaving the thermometer for a while, I got a reading, which you can see in the next photo above.
It’s just barely touching 25C/77F! This is great, as cold is the big issue here. The ambient temperature really should be about 20-24C/68-75F
Since the heat is under the trays, that will warm up any water that is in them which, in turn, will warm up the soil and seed starter mixes. Not by a lot, but enough to hopefully keep the chill off the roots. Plus, it will be better for the fresh pepper and eggplant seeds I sowed to hopefully replace the ones eaten by a mouse or whatever it was.
The hygrometer reading is low, though. Ideally, it should be between 50% and 60% – even 70% for some plants. Hopefully, the bottom watering and occasional misting helps counter the ambient humidity at least a bit.
The celery seedlings now have a nice deep roll to spread their roots into, so they should be good in there for a while.
Hopefully, they will survive this! I seem to remember that I used the entire packet of seeds for this, so there’s no trying again if they don’t make it.
Well, we shall see, soon enough, I guess!
