Please help! The majority of my plants are thriving but I cannot for the life of me revive my poor philodendron. He used to be full of leaves but now he is bare and has some browning and yellowing of leaves. I posted before and after pictures. The newer leaves look nice and green! Am I overwatering or underwatering? How often do philodendrons normally need watering? I did recently buy a water meter. Should I wait until the soil is completely dry?
