I've heard that it's good to bury up to the cotyledon leaves when transplanting into a new pot. But I've also heard that burying a stem too late in a grow can cause the stem to rot. My plants are just starting their fourth set of true leaves. The stem is quite long and has kind of spiraled up. It's more rigid than a few days ago. Is my plant too old to bury the stem when I transplant?
Thanks
