Help my peace lily? (Links to photos attached)
Hi, IÂm new to the board and desperately seeking help for my sick peace lily. I have had her for about 5 years. When I got her she was a much larger plant but had suffered sun damage from being abandoned outside. After about 2 years she had turned over all of her leaves and was pretty healthy, flowering occasionally, but growing more in the winter than the spring/summer. Around year 3 I took her into a plant store and they up-potted her to a 12" pot. She did well for about a year but then started to decline consistently. About 4 months ago I took her into the plant store again (probably her 6th trip in the past 5 years) and they down-potted her into the pot you see in the pictures. They told me the roots looked healthy, the soil looked fine, and were unable to diagnose the cause of the decline in health. I have been trying everything I can but the deterioration continues. The leaves start getting brown on the tips and systematically dry out until they fall off. In the 4 months since the down-potting I think she has lost 6-8 leaves but has only grown 2 new ones (although I am encouraged by the fact that the new leaves grew out of the root cluster that looked the least healthy and had lost the most leaves).
I have read a lot of tips but none of them seem to be working. I water about every other week when the top inch of soil starts to dry out. I filter the water I use with a Brita filter. I water her in the sink so that I can pour about Â½ gallon of water and let it drain out the bottom. The plant stores have all recommended liberal watering but IÂve also read that overwatering can cause the symptoms I am experiencing. SheÂs in a plastic pot with one drainage hole at the bottom, which is what they suggested at the plant store. Is this okay? For a while I had been fertilizing at every watering but then I cut back to about every second month. I have her about 15 feet from the window so there is little to no direct light. Also, the windows have UV coating and have the light-filtering curtain drawn about 50% of the time, but the room gets enough light to sustain my medium-light plants. IÂve heard that fluorescent lights sometimes help Â should I buy one? The temperature is about 70 degrees year-round. The plant store told me that misting is ineffective Â is this true? Would a humidifier help?
This plant has immense sentimental value and I will do anything that could help save her. The new growth is encouraging but she keeps losing leaves. Any help would be greatly appreciated.
I can't figure out how to attach photos here, but I have included links to two photos of my plant.
Thank you all SO much!
