I have a Pothos Joy plant I’ve had for 15 years now. Lately over the past month and a half it’s not drying out. I haven’t changed the location and according to the app it’s in a good spot. It looks healthy but I have had to skip watering it and fertilizing it but it’s still too moist. The plant meter I have seems to be working fine in all my other plants, of which I have about 40!!!! So what’s up with my Pothos not drying out? Any suggestions, please?????!!!! Thank you.
