Peace lilies’ beautiful white showy flowers, dark green round leaves, and subtle scents make us gardeners want to have them all over our garden and homes. Because its flowers are special structures involved in reproduction, it is important to know this plant’s blooming season and its duration.

Peace lilies bloom in spring and early summer. In these seasons, days are longer, and the light is bright. Nonetheless, direct light scorches their leaves and flowers. So, they require indirect light. Thus, the season-best for blooming is spring. However, peace lilies occasionally bloom again in autumn.

What Month Do Peace Lilies Bloom?

Peace lilies bloom in March. Because from March to June, there is an adequate supply of sunlight and minimal supply of moisture.

During these months, they receive the conditions they need for growth. The misty weather gives water and the longer day experienced means they have more sunlight. Also, from March to June, the plant’s life is refreshed, new leaves are sprouted, and scanty trees get full of leaves and flowers.

How Often Do Peace Lilies Bloom?

Peace lilies bloom twice a year. Either in spring or early summer, or fall.

There is no doubt that peace lilies are special plants. In my first time gardening peace lilies, I got ready for my babies to bloom from March to July, only to realize that they bloom from September to December. I was amazed!

Many thoughts crossed my mind as to why it should be that way. Could peace lilies be late bloomers? Or could they have an extended blooming period?

The answer to both questions is no! Peace lilies are neither late bloomers nor long-term bloomers. They are just special plants that bloom twice a year in two different seasons.

The fall season is a transition of summer and winter. This season gives the peace lilies a fresh start on growth after spring. In fall, the cold weather causes less stress on the plant, making the root establish a comfortable environment before winter. This is why, peace lilies bloom in the fall.

Why Doesn’t my Peace Lily Have Flowers?

The major reasons why your peace lily doesn’t have flowers may be due to insufficient lighting, poor watering, fertilizer problems, temperature problems, and aging or root-bound plant.

1. Inappropriate Lightning

Peace lily leaves will burn when exposed to direct sunlight. This would cause the inability to produce flowers. Again, the plant won’t bloom in the shade or a dark room. Peace lily requires sunlight. However, excess of it is bad, and little or nothing is also bad.

2. Poor Watering

Your peace lily may not bloom because you have overwatered the plant or waited too long to water. Underwatering makes the plant wilt, change color, and overwatering makes the peace lily weak. A minimal amount of water is advised.

3. Fertilizer Problems

The application of too much fertilizer on peace lily could cause a decrease in growth, weakness, and vulnerability to pests and diseases. The peace lily will not produce flowers when too much fertilizer is applied. It could cause stunted growth, wilting, shedding of leaves, and even death of the plant.

4. Temperature Problems

Extremely high temperatures and low temperatures would not allow peace lilies to bloom. They are very fragile and, as such, do not require harsh weather conditions. When the temperature is too high, soil temperatures increase too, causing problems for peace lilies.

When the temperature of the soil rises to the point it’s no longer safe, the plant is denied enough water and nutrients, thereby causing harm to the plant.

Furthermore, when the temperature is too low, the plant enzyme activity rate decreases, which disrupts plant nutrient intake. This can cause the peace lily not to produce flowers.

5. Aging or Root-binding

When peace lilies are grown in containers, they mature and have bigger roots. This makes the plant outgrow the container or pot.

The roots will form a tight mass that will overwhelm the container or pot and, eventually, strangles the plant. This would cause ill health, leaf drop, and no growth. This might be a reason why your peace lilies aren’t producing flowers.

How Do You Get a Peace Lily to Produce Flowers?

Growing a peace lily without visible flowers can be very frustrating. Especially, when they’re grown as ornamental plants in the home. To get your peace lily to produce flowers, the following could be helpful:

1. Proper Lighting

Peace lily plants require indirect but bright sunlight to grow. They do not grow properly in a dark room. So, it is advisable to plant them where they can get bright sunlight.

However, when the sun gets too much, you should move them. If this is followed properly, your peace lily won’t lack sunlight and won’t receive too many direct rays of the sun, thus, making it convenient to produce flowers.

2. Adequate Temperature

When the temperature is minimal, peace lilies produce flowers. This is because temperature influences most plant processes such as photosynthesis, transpiration, respiration, germination, and flowering. If the temperature is normal, peace lilies produce beautiful flowers.

Peace lily requires a temperature range of 60°F – 70°F. If the temperature is lower or higher than this range, then your peace lily plant may not flower.

Peace lily plants can live in a range of conditions, but the temperature mentioned above is needed for rapid growth.

3. Adequate Watering

Watering should not be done at all times. Peace lily needs moist soil, so overwatering should be avoided. They can tolerate a short period of dry soil, but their leaves will turn brown if left for a long time.

Again, it would help if you didn’t water peace lily plants with tap water. You should use distilled water. This is because peace lilies are sensitive to chemicals in tap water like fluoride, which causes brown leaves and slow or no flowering.

4. Fertilizer Application

Peace lilies do not need a lot of fertilizer. However, they still benefit from it. Synthetic fertilizers are not advisable as they cause burn on the leaves. Organic fertilizers should be used for peace lilies.

You should apply fertilizers after six weeks of planting for growth stimulation. Once this is done, liquid fertilizers like compost manure. However, there’s no harm if fertilizers aren’t applied.

5. Repotting

It would help if you repotted peace lilies once you notice it’s outgrowing its pot or container. A pot that is at least two inches wider than the old pot should be used.

Don’t try to grab the plant and pull it out of the pot, else, it might cause damage to the leaves and stem. Rather, place your hands around the plant’s base at the soil level and use your other hand to turn the pot upside down.

This allows the force of gravity to gently ease the plant out of the pot. It is good to do this because the peace lily has more room to grow, fresh soil will also do good as the previous one may have become short of nutrients over time. This would help to produce flowers.


Peace lily plants produce flowers in spring and also in fall. It blooms twice a year. This means if you waited in spring and got a little bit disappointed, then you can fix things to get your desires in fall. 

It is important to know plants and seasons. This would help make planting easier for you. Peace lily plants bloom when the necessary conditions are met. These are lightning, fertilizers, repotting, and watering. I hope this article was helpful!
