Q.Browning tips & leggy vines

Zone Boston, MA | lilygould added on September 12, 2019 | Answered

Some of the leaves on my polka dot plant seem to be getting brown tips and turning a yellowish color, and I’m not sure why. It sits in a West-facing window and I don’t let it dry out too much between waterings. Any ideas on why this might be happening? Also, as you can see from the bird’s-eye image, some of the stems are coming from the middle in weird, vine-like formations. Any ideas about that? Thanks in advance for the help!

They are being overwatered and not receiving the correct DURATION of light. They don't tolerate direct light, but they do like bright light. Window light, even South facing, will not be enough to scorch these plants, and will give you the duration of light that you need. Alternatively, you can try using a small horticultural grade lamp.

As for the fungal infection... It is best to let these dry out very thoroughly down to about 2 inches. Not doing so causes what you are seeing now. Wet Feet=Fungal Infection.

I would treat with a fungicide. this article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
