Lush green foliage with white flowers are what makes peace lilies one of the most recognizable and popular houseplants. The good news is that most causes of yellowing leaves can be managed and addressed by changing your plant care routine.
I will cover the possible causes of leaves turning yellow on your peace lily and offer my recommendations on how to fix this issue. By checking each case, you may zero in on the issue and help your peace lily plant bounce back to good health.
Hopefully, my article will accomplish two things — will keep you from panicking over something that could be as simple as aging leaves, and quickly identifying the cause behind yellowing leaves. But then and now, aphids, mealybugs and spider mites may appear on your plant. If left unchecked, an infestation can develop that can and will cause the leaves of your peace lily to turn yellow. In case of a mild infestation, wiping the leaves clean will usually help get rid of the problems.
More severe cases will need treatment with an insecticide. There are two particularly dangerous fungi for peace lily plants, namely the Cylindrocladium spathiphyllum and the Phytophthora parasitica.
This will prevent the buildup of excess salt in the growing medium. When a plant is in a pot without a drainage hole, salts may build up in the growing medium. Once repotted, it is a good idea to thoroughly flush the pot with clear water. Repeat the flushing process about an hour later to remove additional salts that will have dissolved. You could also repot it into fresh growing medium and avoid fertilizing for a month or so. Some other things that can cause problems with a peace lily — but are unlikely in your situation at this time of year — would be cold injury caused by drafts or temperatures below 40 degrees Fahrenheit.
The peace lily makes a great houseplant because it thrives in the typical indoor temperature range of 65 to 80 degrees. Keep the peace lily away from noninsulated windows and doors this winter because cold drafts will harm it. Temperatures above 90 degrees can cause leaf curling, yellowing and browning. Low humidity, which is common indoors during the winter heating season, can cause brown tips on the leaves.
Remove leaves that have a lot of damage, and carefully trim off the brown on other leaves. Skip to content. Tap water, as you may know, has many additives in it and a lot of those are not good for plants or human consumption.
The main concern with tap water is calcium. Too much will cause leaf discoloration including yellowing, brown spots and in the worst case — blackening of the leaves.
These are mineral deposits from harsh water chemicals. If those are present, use bottled water to flush the soil getting rid of the mineral build up. Trim the ruined leaves off and go back to watering as usual, only this time with filtered water. The bottom leaves will naturally turn yellow. This is natural and the leaves closer to the base of the plant do need more regular pruning. What we see as a single flower on a peace lily is actually a cluster of tiny flowers attached to one big white leaf.
Each stalk on a peace lily can only flower once. The stalk has done its job and the entire stalk is then useless because it only flowers once. Once the flower starts to turn from white to green and wilt, prune it from the base of the plant. If you only trim the tip of the stalk, the leaves at the base of the plant will naturally turn yellow and die. Just prune off the discolored leaves to let a new stalk grow in.
They only need fertilizer added every weeks. They last for up to two months and all you need to do is poke a stick into the plant soil and leave it there.
A good practice is to allow tap water to stay overnight before watering your favorite houseplant. It allows the chlorine gas to evaporate and prevents harming your indoor plant. Another alternative is to consider using filtered or distilled water. The water is free from mineralization and ideal for watering your peace lily plant. Peace lilies thrive under a temperature range of o F.
The temperature condition enables the plant to develop broad and stunning tropical leaves. Yellow leaves on the peace lily plant occur due to extreme temperatures. These tropical plants hate cold drafts and too much heat. Cold drafts usually result in cold porch on the leaves that trigger yellowing or browning. The best option is to move the plant away from a draft-free location. Ensure the indoor temperature mimic their natural habitat for better growth and health. Peace lilies are not heavy feeders.
But these plants need basic nutrition to thrive and attain full potential when grown in the house. Magnesium and iron deficiencies in the potting soil are responsible for peace lily leaves turning yellow.
The issue usually makes foliages turn yellow and veins retain their green color. Use homemade plant fertilizer to keep your peace lilies happy. It will provide the necessary nutrients and minerals that foster better growth. Read my article on how to make homemade fertilizers for a houseplant.
Organic fertilizers are harmless to indoor plants regardless of the usage methods. You can also use artificial fertilizer to supply adequate nutrients. I recommend using a proper portion of liquid fertilizer to fix the leaf problem. Peace lily plants are easy-going houseplants. Re-potting and transplanting to prevent root-bound issues is never a big deal.
But the shock may cause the development of yellow leaves. Peace lily leaves turning yellow after re-potting is normal. It is an indicator that the plant is trying to acclimate from the transplant shock.
Provide tender care, and soon, new growth will show up. If the issue persists, try to investigate other possible causes and fix them. Aging is inevitable in plants.
