Monstera deliciosa, Swiss Cheese Plant, etc etc! But I can't seem to figure out what is the problem with it! It is in a spot with bright light but no direct sunlight falls on it... I water it when the soil is almost dry to the touch... The potting mix has some wonderful vermicompost in a sandy mix, so it free draining... I could fertilize it but I don't want to do that without first figuring out what is the problem... is it a fungal infection? Any info will be greatly appreciated! Thanx a ton in advance, all you wonderful people! : )
