I have had a bonsai tree for a few months now and it is growing well. However the other day i noticed a little sapling starting to grow in the soil. My question is whether or not i can put it into another pot and grow it or just to leave it.
Yes, you can. It won't disturb the Bonsai(although it may kill the plant you're moving if you're not fast enough).
It may, as parker pointed out, be a weed, so please do post a picture.
