Hello. I have a spider plant (well, it's two in one pot), and the tips of the leaves are turning brown. The plantlets are ok (there are about 18 of them), but the leaves on the Momma plant and some of the leaves that grow over the node things on the stems are brown. Does anyone know what can cause this? Also, out of curiosity, how come some plantlets grow at the end of their own stem, but some of them grow straight out of a node on the stem without their own stem? I had a stem where the plantlet broke off accidentally, but now there are three plantlets growing out of that stem without their own stems... I don't know if that makes sense.
