Hi! I'm new here. I have been all over the internet and cannot seem to find the answer to my problem.
I have a peace lily and anthirium. I got the anthirium about a month ago and have had the peace lily for 4 years.
The peace lily has had a problem of the new growth turning brown BEFORE it unfurls. Then the leaf dies and the process continues but the plant itself doesnt die. Then I take it outside in summer (zone 6) and it does beautifully. It triples in size and no problem of dying new growth. But every winter I bring it back inside and it just survives the winter without new growth making it and also old leaves turn brown. Now the new plant (anthirium) is doing it as well.
Why is this happening?! Its been driving me nuts for years!
The pic below of the peace lily shows how the old growth turns brown. And the other pic shows what the new growth looks like.

What are you fertilizing with?

Nothing. Lol. Should I be? I dont fertilize any of my other houseplants because everytime I do, I seem to make them very unhappy. All my other houseplants are quite healthy. It's just these 2.

No, if they are healthy and green there is no need to fertilize them. Does your soil have fertilizer in it like some to like miracle-gro?

The soil of my peace lily does. Well, it has 3 year old miracle gro potting soil. So I doubt theres any left in there. My thing is, it does GREAT outdoors in the summer. Wait, I just realized, I do fertilize it when its outside because I give all my outdoor potted plants a single dosing around mid season. I feel so silly, I never thought of fertilizer because I was so hung up on the indoor/outdoor thing.

Give it as much light as you can. And give it a little fertilizer. It looks like it has either Potassium or Potash deficiency.

Sorry, I meant Nitrogen or Potash deficiency.

Thank you soooooo much! I have him under an led grow light that I call my plant "hospital" because I couldn't think of what else to do. So I'm gonna give him a little bit of fertilizer and see if it helps. Thanks again. Truly. It has been 3 years and I just was so hung up on the outside thing that I was worried about light/temp/humidity and never even thought 1 second about fertilizer.

Don't give a houseplant more than 1/4 recommended dose until you see if it helps.

Good call. Most never need more than a half dose and for some that can be too much.

I don't think that nutrient deficiency is the problem here. Your Peace Lily is reacting to the very significant changes in its environment that it experiences twice every year. Outdoor light - even in shade - is much more intense than indoor light. The change in light affects its growth but also its water usage. Indoors in low light, it will use less water than when outdoors, so watering as well as light could be a problem. Leaves adapt to the light they receive at the time they emerge. When that light changes significantly, the older leaves tend to suffer while the new leaves adapt to the new light intensity. Consistent light year round is important.

Of course, you can't leave yours outside year round, so my recommendation would be to find a good indoor location close to a north or east window and leave it there year round. That will be less stressful to the plant and make it easier for you to water it consistently. You may not get the surge in growth it gets outdoors, but you will also avoid the leaf loss in winter.

Your Anthurium problem is entirely different. It appears that other than one yellow leaf, there are two flower stems that have died back normally. Correct me if I am wrong about that. In general, your Anthurium will need more indoor light than your Peace Lily. Keep it close to a moderately sunny window. I cannot see how it is potted or repotted, so it is hard to advise you on proper watering.

I always water my plants according to feel (weight of pot mostly) so I dont think watering really fluctuates too much. It is under a roof when outside getting only direct morning sun for about 2 hours. Then indirect sun for another 5 hours. I have horrible lighting indoors in winter, mostly east facing windows and 30' trees surrounding my property, so my only choice for anything but low light plants, is under an artificial grow light, which I run for 10 hours a day in the winter months. The anthirium is new for me, so if that's normal for the flowers, I was unaware. I'll keep an eye out.
I used to keep the peace lily in the only room I have with SW windows, about 6 ft from the windows themselves. I just switched to the grow light station instead thinking it may help. Should I put him back in the less light conditions?

By all means keep it under the grow light and give it a little fertilizer.

A basic rule for growing under lights. Halving the distance to the light doubles the amount of light received. Doubling the distance from the light lowers the amount of light the plant receives by half.

WillC and I do not always agree. But we are both gardeners and both want to help. I have many years of caring for plants under my belt. WillC is smart and I have no doubt he many years of plant care under his belt too. But you will have to decide what is best for your plants.

Best of luck to you.

You may not realize how much more intense the outdoor light - even indirect - is than indoor light - even when supplemented. Your Peace Lily is struggling to adapt to those changes in light. The lights will help some, but I suggest you move it closer to the window just beyond the reach of the sun's rays.
