I've had my Monstera deliciosa for about eight months now, and I'm still figuring out the watering situation. Mine's finally putting out a new leaf with the characteristic fenestration, which is exciting! But I'm confused about whether I should be fertilizing more often during the growing season. I've read conflicting advice online. Does anyone else struggle with the balance between keeping the soil moist and not overwatering? I'd love to hear what works for your Swiss cheese plant.
