Ask The Expert: I have received a Spathiphyllum plant and it is blooming. Some of the blooms have turned brown and wilted. Do I clip the dead blooms off? If so,where on the stem should they be clipped? Glynda
Plant Expert Reply:
Yes, you need to clip the old peace lily (Spathiphyllum) blooms off. Follow the bloom stalk down to the base of the plant and clip it off. This will make the plant more attractive and it will send a signal to the plant that it needs to bloom again.

during our relocation from tennessee to georgia my 2 lilies have been in a nephews garage from june until now. I know that the weather was in the 90’s to 100’s during the summer and recently it has been in the teens at night. I would like to bring them back inside and need to know what I need to do to make them inside plants again. They have wilted considerably and alot of the larger leaves are brown half ways. any suggestions would be appreciated. Teresa

You plants are already in shock and they will probably look worst before they look better. But, I think they will recover. Anytime you move a plant from outside in to your home check for any signs of pests. During times of stress plants are more susceptible to pests and other pathogen attacks. If you have a pest or fungal problem, you will need to get rid of them. Send me a picture of the pest or problem and I will instruct you on how to get rid of them.
To care for the peace lilies when you take them inside, begin by removing all damaged leaves. Place in an area where the plants will receive bright filtered light, natural if possible. Make sure your drain holes are working and are not obstructed. Keep the plant evenly moist. Do not over-water — the peace lilies will not need as much water as it did outside.
Now for the hard part, wait. You will need to patiently wait while the plants works through the shock of being moved. In a couple of weeks, you should start to see new growth appear. As the new growth appears, you can give the peace lilies a very light solution of water-soluble fertilizer. Now the peace lilies should be fully acclimated houseplants.

my peace plant is beautiful, I am trying to keep it that way as it is from my husbands funeral, ? THE WHITE FLOWERS HAVE TURNED GREEN , they are still looking good after 2 months are they suppose to die off and when, will they grow back again? Mary
Plant Expert Reply:
As with all flowers, the peace lily blooms will eventually die. When they do follow the flower stalk to the base of the plant and cut it off. It will rebloom again any where from a few months to a year – depending on the environment and the cultivar. To ensure you give the plant what it needs, I suggest you read our peace lily care instructions. The key to keeping it healthy is a evenly moist soil and bright filtered light. Good luck and keep me posted.
Ask the Expert: Peace lily won’t flower
Hi.
I had a peace lily that was healthy, and flowered lots. One day (about a year ago) I decided it was pot bound, and as it divided easily, split it into several ‘new’ plants and repotted each of these. All have done well, continues to grow and look healthy – dark green glossy leaves, but none of them have flowered. all the plants have different conditions (given away to family and friends) and I’ve tried moving mine between rooms to try different light levels.
What do I need to do to get the plant to flower? or did dividing it ‘kill’ the flowers? Sarah
Plant Expert Reply:
Dividing the peace lily did not kill the ability of the plant to flower. The natural cycle of a peace lily is a 3 to 4 month blooming period per year. Hybrid varieties may have different blooming cycles that occur more often or they have been chemically manipulated (with a hormone called Gibberellic acid – GA 3 ) to bloom.
Light and humidity are the natural factors that inhibit or stimulate the blooming of a peace lily. In your case, another factor maybe a contributing factor – maturity. One of the reasons peace lilies have been hybridized is that the original Spathiphyllum needed maturity and size before it would bloom. This often meant more than a year’s growth before the plant would bloom. You plant may simply lack maturity. You didn’t say how long it has been since you divided the peace lily. If it has only been a few months give it a little more time. When the plant has “matured”, it should bloom.
In the mean time, I would make sure the plant is receiving the right amount of humidity and light. You can find more Peace Lily Care information on the Peace Lily page on FSN. If you want to learn more about peace lily blooming, read Making Peace Lilies Bloom.
Good Luck and keep me posted.
Ask The Expert: I split and transplanted my peace lilly plant. It didn’t do well so I cut it way back and now it isn’t growing at all. Will it ever grow back, or should I throw it out? How do you start new plants if you want to start from some slips? M Moe
Plant Expert Reply:
Have you or a friend ever died your/their hair, decided it wasn’t just right and then cut your/their hair off to correct the bad dye job, only to be further frustrated by the time it takes for the hair to grow back? I ask because at some point in all our lives this scenario has happened. What is the one thing that could have prevent all the problems? PATIENCE.
Patience is what your peace lily needs. After you split and transplant a peace lily, it will look a little rough. Provided you didn’t plant the peace lily too deep, it will rebound and form new growth in a few weeks.
If you cut all of the peace lily foliage off, the plant will struggle to complete the photosynthesis process which all plants need to survive. This doesn’t mean that the peace lily won’t survive. It does mean that the road to health and beauty will be much longer. Again, it will need patience.
As long as the plant has not turned black, mushy or smell, it should form new leaves and recover. Make sure the roots stay moist but not soggy. The plant will not use as much water as it did when it had leaves. You can give it a light solution of vitamin b1 or fertilizer to help stimulate growth. Be careful not to give it too much fertilizer since the plant is already stressed.
The way to propagate peace lilies effectively is by splitting them. As long as the piece you separate from the mother plant has a good root system and healthy foliage, it can be planted to start a new peace lily.
So give your peace lily a little time. You may be pleasantly surprised in a couple weeks with new healthy foliage. Good luck and keep me posted. If your plant doesn’t make it you can always order a peace lily from your local florist.
Ask The Expert: I read your article on Peace Lily – (Spathiphyllum clevelandii) but didn’t see anything on how to propagate it.
Is it similar to a Hosta, (plantain )lily?
Thanks, JH
Plant Expert Reply:
Yes it is basically the same process. You create new peace lily plants by dividing them. Propagate by removing the peace lily from it’s container; then take a sharp knife and cut the plant from the roots to the top of the plant – this will ensure that each plants has an ample amount of roots. Take the divide pieces and follow the re-potting instructions. The new container will need to be same size as original container.
Peace Lily Re-potting Instructions
Peace lilies (Spathiphyllum) should be re-potted when the root growth has overfilled the container. Use a humus rich potting soil to repot the peace lily. To help the roots to retain soil and prevent the root tearing, re-pot the plant when the soil is somewhat moist. For determining pot size follow this rule of thumb; use a pot that is 1½ times the size of the previous pot. When placing the peace lily in it’s new pot, keep the plant level the same as it was in the old pot (fill the pot so that the top of the root-ball is at the same level as before). After re-potting, water slightly to remove any air bubbles that might have occurred and wait a couple of weeks before fertilizing.
Ask the Expert: Peace Lily care
I purchased a peace lily about 4 weeks ago for my office. It is not in direct sunlight, I have been watering it regularly to keep the soil moist, and spray the leaves. However, the leaves are CONSTANTLY turning yellow. Everyday there are new yellow leaves appearing. Any suggestions? How often should I be watering the plant. Lisa
Plant Expert Reply:
I believe your plant is receiving too much water. Peace lilies generally get by with once a week watering. If they are in a climate that is cooler or has low light levels, the peace lily (Spathiphyllum) can go even longer between watering. The first thing to check is drainage. Make sure your container allows the plant to drain off excess water. Once the water issue is corrected it will take a couple of weeks for the plant to fully recover. The first sign of recovery will be new green leaves. Good luck and keep me posted.

Ask The Expert:
I have a Peace Lily and I am noticing that some of the leaves (at the tips) are turning black. What is causing that? I have been cutting off the black parts, is that OK?
Thank you for your time. bfh
Plant Expert Reply:
There are 3 things that can cause peace lilies to turn black.
The first is a water issue – too much or too little. With water the leaves turn brown first then black.
The second is exposure to an extreme temperature change. Exposure to extreme cold will turn the peace lily leaves black. Exposure to extreme heat or sunlight usually causes a yellow/brownish discoloration before it becomes black.
The third is a fungus called Phytophthora (aerial blight). With this fungus you need to keep water off the foliage – that is how the fungus spreads. You may need to treat both the soil and the foliage with a fungicide. Check with your local nursery & garden center for the appropriate fungcide.

Ask the Expert: why won’t the bud on my peace lily open
My peace lily the bud started to open now it is closed tighter than tight. Cecilia
Plant Expert Reply:
A severe temperature change or lack of water will cause spathiphyllum bud maturity problems. Make sure your peace lily is moist but not soggy and the air flow around the plant is remaining constant. I suggest you check for thrips. I’m not sure of thrips effect peace lilies the same as they do roses, but thrips keep rose blooms from opening. Thrips are a small slender insect.

Does my peace lily need to have any sunlight? Right now I do not have it near a window at all. Anne
Plant Expert Reply:
Peace lilies (Spathiphyllum) prefers bright filtered natural light. However, the peace lily is tolerant of low light levels making it an excellent houseplant. It can be used outdoors in warm humid areas with filtered light or partial shade. Exposure to direct light may cause yellowing leaves with a burnt appearance.
