After more attempts than I would like to admit, I finally managed to germinate some Camellia Sinensis (tea) seeds. There are around nine of them, and it's gotten to the point where almost all of them are around 4 inches tall, and have 2-4 big leaves. There are three to a pot (the soil is just the basic Miracle Grow seet starting mix), and I'm worried about them starting to be overcrowded. What's my next step here? Should I put them in separate pots with some proper potting soil? These plants seem to be hardy from what I've read online, but I don't want to risk it. Any help is much appreciated. Thanks!
