How To Increase the Life Span of Peace Lilies?

You can increase the lifespan of peace lilies by growing them under moderate to low light conditions, moist soil with low humidity, minimal use of fertilizer and the right watering schedule. You must remember to repot it, and keep the pests away, and enhance regular maintenance.

– Water Right

As you think about of the question, can a peace lily live for 20 years, of course, they can. Peace lily plants tolerate more drought than over-watering, thus always make sure you do not overwater your plant as it could be hazardous to it.

Excess watering makes the plant susceptible to developing fungal diseases and root rot, which over time can affect the longevity of the plant. At the same time, do not let the soil go completely bone dry as this could result in yellow leaves and wilting foliage. 

Watering Peace Lilies in House

The ideal way to water the plant is to check for moisture levels first, you may place your finger in by an inch and feel for wetness, and then add in more. Use water at room temperature instead of standard tap water, or rainwater collected and filtered will also be suitable for the plant.

Don’t forget the key feature that you must water as per the season by scaling back in winter and increasing the frequency on hot summer days, otherwise watering once a week is sufficient.

– Reduce Fertilizer Use

Want a 20 year old peace lily in your garden, it is simply you may be shortening the life of a peace lily by using an overdose of fertilizers. Or, the wrong type of fertilizer may be even hampering its health and well-being. Your peace lily plant is sensitive to non-organic and synthetic fertilizers, which can drastically shorten their lives. 

Reducing Fertilizer for Peace Lily

The plant can easily develop adverse reactions to chemical formulas. Thus giving the plant a well-balanced organic fertilizer applied just twice a year. Do not fertilize the plant in winter, but just in spring or summer. If you notice your leaves turning a black color, it is a clear sign that the fertilizing isn’t going right. 

– Keep the Humidity High

At low humidity levels, you are not going to see even a 10 year old peace lily living for long or sustaining healthy foliage. These are rainforest-based tropical plants, so love a lot of humidity around it. 

If you increase the humidity indoors, they will thrive, because how long they live depends a lot on the care and the environment they are given. Overall, this is because the indoor variants live longer than their counterparts grown outdoors. 

Thus, maintaining a humidity level between 60 percent and 70 percent is required. If you are growing your plant in a dry zone or during hot summers, then increase humidity by misting the plant often. 

Alternatively, you could either group them with other plants to take advantage of collective transpiration or place a pebble tray below the container or pot. As the water in the tray would evaporate, the humidity around the plant will increase. 

Look out for leaves with brown tips, which is a clear indication that you are growing your plant in low humidity. If you are growing your plant indoors, use a plant humidifier, because this can easily kick in some moisture around. 

– Give It Diffused Light

Your peace lily flower plant dislikes harsh and direct sunlight, which can make it wither away soon. What the plant thrives best in is bright yet indirect light, away from extreme exposure.

The plant is robust and manages to sustain foliage and low light, however seldom will it tolerate direct sunlight. Thus, you can create a greenhouse effect around it, placing it under larger tree canopies or placing a green garden sheet over it to diffuse the light. 

Peace Lily Plant in Diffused Light

The sign that your plant is in its ideal light condition is when you notice its unique, adequate white peace lily flowers blooming and specialized leaves. If you are growing them as indoor plants move them near the north or east-facing window behind shear curtains for some filtered light. 

At the same time, avoid extremely dark and dingy corners as these are not optimal for the plant as well. In such cases take the help of artificial lighting such as grow or fluorescent lighting which will take care of its needs. 

– Grow Them at Moderate Temperatures

Peace lilies love the warmth of rain forests, thereby preferring to thrive in moderate temperatures between the range of 68 degrees to 85 degrees Fahrenheit. Keep its temperatures lower than this, and surely you may end up shortening its life. 

Note that having lower temperatures would damage the roots, and would lead to making the plant weak and limp. Under extreme cold with the roots frozen below the soil, it will seldom be able to absorb the required nutrients or water, thus it will paralyze the growth and health of the plant.

Protect the plant from frost, chilly winds and cold drafts. It is highly recommended to move the plant indoors or to a closed space like a garage in extreme winters, sheltering it from the chills. 

Moreover, it is important to shield your peace lily plant from fluctuation or sudden changes in temperatures. Sudden increases or decreases put the plant under tremendous stress, making the leaves turn black and affecting the longevity of its life.

– Keep Pests at Bay

Mites and mealybugs are notorious garden pests that can infect the peace lily and shorten its life. These insects live on the plant’s foliage, feeding through the leaves, stems and sometimes even deep into the roots. 

This can destroy the plant in its entirety in no time. The earliest signs of pest infestation are the visibility of eggs or larvae in the clusters, especially on the underside of lily leaves and stems.

Keep Pests Away from Peace Lily

If you do not wish to add any chemicals, you can always treat with an organic solution made of neem oil, onion peel, garlic peel or orange peel whose odors irritate the pests and make them leave the foliage, or an organic solution of neem oil will also do the job.

– Soil

Heavy or loamy soil will not make your peace lily plants go a long way. What the plant needs to sustain its health and foliage is light and well-draining soil.

Heavy soils tend to retain moisture which these drought-resistant plants do not prefer. Moreover, excessive moisture in the soil also puts the plant at risk of developing root rot or fungal diseases. 

To make the soil lighter, you can use potting soil mixed with peat or perlite for better the serration. Additionally, also throw in some orchid bark or worm castings that will permit flow out of the water easily.

However, make sure you maintain the soil slightly acidic between a pH of 5.0 to 6.5 and include organic manure to nourish the soil. Well. These measures would eventually go a long way in keeping the life expectancy of the peace lily high.

– Re-pot Every Year

To make the health of your peace lily better and extend its life ahead, repot it annually. The plant outgrows its pot every year, thus move a size up to prevent root-bound and keep it going. 

It is very simple, you would have to repot in fresh potting soil which will reduce the risk of bacterial, fungal and pest infestations. The ideal time to repot is in late winter, just before the new shoots begin to appear in early spring.

Repotting Peace Lily Plants

Simply, if you find your plant growing too large for its pot, transplant it into a pot one size bigger to prevent root-bound plants. 

The pot or container you are growing your peace lily needs to have well-draining holes. Make sure it isn’t clogged with debris, gravel, or even stones that can choke holes holding up water within the soil. 

– Regular Maintenance

Prune your peace lily regularly, removing dead, decayed and diseased leaves. Also, clear all debris around the plant, as they can put the plant at risk of contracting infections. Always snip the foliage with a sterile garden pruner or knife so that bacterial and fungal diseases are not spread to the plant.

Maintaining Peace Lily Regularly

Remember to cut stalks as close as possible, meaning at the base of the plant, this is to help the plant conserve energy through the dead stalk. Also, snip away yellowed and wilted leaves so that you can make space for new and fresh leaf growth. 

Whether you are growing it as an indoor plant or as outdoor foliage, you could easily provide the right care and have the plant thriving for decades. This is not difficult as the plant does not demand much and even does a great job purifying the surrounding air.
