I've had my ZZ plant (Zamioculcas zamiifolia) for about eight months now and I'm still figuring out the watering schedule. It's in a bright corner of my flat and honestly looks pretty happy, but I'm paranoid about overwatering since I've read they're prone to root rot. Should I wait until the soil is completely dry, or is there a middle ground? I'd love to share a photo of mine if I could upload here—the leaflets are looking really glossy lately and I'm wondering if that's normal or a sign something's off.
