I recently got a peace lily as I heard it is a low maintenance plant and also acts as an air purifier. I initially placed it near a window where it got bright light. The tips of the leaves and some leaves started turning yellow. I pruned them off and changed the position again. Now it is near a north facing window where it gets bright but indirect light. As for watering, I did allow it to droop a bit before I watered again. To be honest, the pot that it came in seems a bit tight. It is hard to dig my finger into the spoil to check for moisture without spilling some of the soil out. But anyway, I keep it moist. I have not fertilized it since I got it from the nursery. Just been a month so far. Now I have the following concerns :-
1) How to know when to prune the peace lily ? Should we wait until the spadix turn black or brown or when the spathe turns green ? In my case, I see both happening .
2) Does my plant look healthy ? The leaves have become upright after watering but they are not exactly erect . Still look a bit curved. Is that normal ?
3) I see some white powder on some of the leaves. Is that pollen or some fungus ? Should I prune that flower stem ?
4) Some of the spathe coverings are showing pointed brown tips. What is that a sign of ?
Thank you all in advance. Still early days with this plant. Dont want to lose it . Appreciate all your suggestions.
