Just the tips of the leaves turn brown on my peace lily and some of the leaves on a lady palm. Have never had this problem before. Both of these plants are indoor plants and in or near a north window. I live in northern Ohio.
Underwatering is most common reason for brown tips/edges in plants. Other possible causes of brown leaf tips could be dry air or too much direct light. Mist the foliage often and make sure it has bright, indirect light. Also, remove the affected leaves.

The leaves on my Peace Lily are turning black on the tips. What could be the problem, and how to solve?
It may be that a fungus is setting in. I would check the soil to see if it is overly moist. You may also want to check the roots for signs of root rot. Here is more information on root rot:

How to winterize the peace lily? Can it be stored in a dark place or must it stay potted with mod light? Thanks.
Peace lilies do not typically go dromant in winter so they must be kept in medium (moderate) light over winter and be sure to keep watering as usual and keep humidity levels up.
I have a large indoor peace lily and on the floor underneath it, it is sticky. I suspect it is a plant sap of sorts and wondered how to remove it.
The plant may have a pest problem and the pests are secreting honeydew. It would be almost the consistency of water, only very sticky. I would recommend spraying down the plant with water and then follow up with a spray treatment of neem oil to take care of the pest in question, likely aphids or mealybugs. The honeydew on the floor can normally be cleaned up with some good old soap and water.
Yea, probably either scale or aphids. I would fix a spray bottle of water, 2 tablespoons of mild liquid detergent (Dr Bonner's is perfect), and 1 teaspoon of alcohol (rubbing type). Spray the plant all over, especially up onto the undersides of the leaves and stems, which is where the bugs are congregating. Let it drip for awhile, then wipe up the floor, which will clean up the sticky there. You will need to repeat the treatment once a week for 2 - 4 weeks, depending on how bad the infestation is. You'll be able to tell when all the bugs are dead because there will be no more sticky stuff.
I recently repotted a peace lily; however, I only added new soil without removing the soil it was currently in. It is placed in a sliding glass window on the east side of the house with plenty of light and next to a heating vent for air circulation. It now has a bad case of mold and our home is infested with gnats. How do I get rid of the mold and gnats? Please help me, as I have a very green thumb and have NEVER experienced this and am quit frustrated.

I want to plant a peace lily bulb that is the only thing left from the plant that died.
"Peace lilies" are not lilies; their botanical name is Spathiphyllum, and they are in the same family as philodendron. Since they are not lilies, they do not make bulbs. They have large underground stems from which the leaves and roots sprout. If what you have is this large stem, called a rhizome, you can try burying it in a pot of soil. Kept SLIGHTLY damp, it might start to regrow, but this is doubtful; If the rest of the plant has died, there is probably little life left in the rhizome. In the future, if you get another peace lily, this article will help you take care of it properly so that it doesn't die: https://www.gardeningknowhow.com/houseplants/peace-lily/peace-lily-plants.htm
If you actually have a bulb from some sort of lily plant, I'll need to know what kind it is to help you with planting it.
