I waaay overseeded my mustard seeds when I planted them in the garden, because the seeds were a few years old and I wasn’t sure what was going to come up.
They desperately need thinning now, but I hate to thin seedlings, because it feels like I’m killing perfectly good plants, and what if I thin one that would have made delicious greens and leave one that turns out to be a dud! I know, I know, it’s completely irrational. If I don’t thin, they won’t be able to grow and I might as well kill all of them.
So, I thinned them. A bit.
The seedlings are so spindly. I was having the same problem with the cilantro. They’re just not getting enough sunlight, I think.
