The strawberry seedlings are also doing well.
Funny update on the "Malabar spinach"... So like a true newbie gardener, I of course didn't mark any of my containers, thinking, "Pshhh...I'm not going to forget what I planted in each container."
After which, I promptly forgot.
So this whole time I've been thinking that the basil seeds were no good and that it must have been my Malabar spinach that had sprouted. Well, now that this little guy is big enough, I was able to compare photos online of Malabar spinach seedlings and this, and what I have sure isn't Malabar spinach. It does look an awful lot like basil seedlings, though. So I'm 99.9% sure that I have a happy, healthy basil seedling on my hands that is ready for transplant.
As soon as the bag of potting soil I ordered arrives, I'll transplant it. Meanwhile, I guess I will try to germinate the Malabar spinach again because I already have a trellis on the way for it!
Sadly, I discovered a couple of fungus gnats on them yesterday after work, so I made up a batch of liquid Castile soap/cinnamon spray and sprayed the leaves and top layer of the soil last night and this morning. I haven't spotted any more gnats, so hopefully it's working.
Since our last update, the leaves continued to yellow. They became dryer and developed a weird rubbery texture. Then last week, I can home from work to find they had fallen off the stem. I picked off the other yellowed leaves since clearly, they were not improving.
Now, a few new leaves have grown on each plant. These leaves look a little greener and healthier, but I'm still not too confident that we'll get any 毛豆 (edamame) out of these guys.
I suspect that it was actually a bad idea for me to try putting vermicompost on them. They definitely got worse after that. I've read online that unlike many other plants, soybeans don't like nitrogen-rich soil since they produce their own nitrogen. Vermicompost is rich in nitrogen, so this was probably not a good combination.
We'll see if the plants perk up after no more fertilizer being added. In retrospect, I should have added fertilizer to only one plant to better test the effects. Live and learn.
