At what point should I thin my tomato seedlings? Right now they're three to a container (pic related is the container) and they each have a set of true leaves.
Also, I've heard that it's possible to get away with not thinning them, by taking the root ball out and trying to "unthread" them. I imagine this has a pretty low success rate, but if that rate is still higher than say 40% it would still be worth it.
