Why Is My Peace Lily Not Growing?

Growing issue is a common problem of a peace lily. Many people are wondering why is my peace lily plant not growing? I also faced the same problem. After 2 months of planting, I noticed my peace lily stopped growing. Then I found some reasons for this problem. 

Why Is My Peace Lily Not Growing

If your peace lily is not growing properly It means they are not getting the right environment like where they are native to. 

  • Insufficient Light: If you are wondering why has my peace lily stopped growing? Then lighting maybe the reason. If your peace lilies are not growing properly, check first if are they getting adequate light or not. Peace lily like shade, too. You can give them in the shade. Peace lilies need bright, indirect light to thrive. If you place them in too low light conditions, they won’t have enough energy to grow. 
  • Overwatering: Remember peace lily like a lot of water Many people think the more I water my plant, the more it will grow. But it is totally a misconception. Too much water can lead to root rot. It hinders the plant’s ability to absorb nutrients and grow. 
  • Underwatering: Indeed, peace lilies don’t need too much water. But conversely, not enough water can cause the plant to conserve energy and not produce growth. Also it can cause your peace lily drooping. 
  • Over Fertilizing: While applying some fertilizer is necessary sometimes, too much fertilizer can damage the roots and prevent new growth of plants. Peace lilies have low fertilizer requirements. 
  • Temperature Extremes: Peace lilies are tropical plants. So that they are sensitive to temperature changes. Extreme temperatures and drafts can stress the plant and impede its growth. 
  • Pests: Pest infestation can be another reason for stopping the growth of peace lily. Infestations can damage the plant’s leaves and stems, which can also stop their growth. 
  • Pot Size:  Many people don’t focus on the pot while it plays a vital role in plant growth and overall health. If you use a too small pot, it will restrict the root system and limit its growth.   
  • Soil Conditions: If you are wondering why is my peace lily not flowering? Then check the soil frist. Peace lilies prefer well-draining soil. Compacted or poor quality soil can affect root health and plant growth. 
  • Humidity: Peace lilies need high humidity levels for their growth. Low humidity can stress the plant and slow down growth. 
  • Age of plant: Consider the age of your peace lily plant. Older peace lilies may grow more slowly than younger ones. This is a natural part of the plant’s life cycle.

How Do You Increase The Growth Of A Peace Lily?

So, how do you increase the growth of your peace lily? To do this, you have to know how to care for a peace lily indoors.

I followed some necessary steps that helped me a lot to increase my peace lilies growth. Let’s see what did I do: 

How Do You Increase The Growth Of A Peace Lily

Provide Bright, Indirect Light

You should know how much light does a peace lily need. At first, I changed the place of my peace lily. After identifying their growth problem, I noticed that my plants were not getting adequate light. I heard they can thrive in a dark corner. It’s true, but for their proper growth, you need to provide some bright, indirect sunlight. They need indirect light for at least 6  hours a day. That’s why I place my peace lily near an east facing window. 

Note: Remember, don’t expose them to direct sunlight. It can scorch their leaves. 

Water Thoroughly

If your peace lilies are not growing properly and you want to increase their growth, then focus on your watering frequency. Because overwatering and underwatering both can impede the growth of your peace lily. You should keep the soil moist but not waterlogged. You can check the soil moisture by touching the top inch of soil. If it feels dry, water your plant.  Peace lilies need drainage to remove excess water. 

Regular Fertilization

While peace lilies are not heavy feeders, to increase their growth, you should provide some fertilizers. During their growing seasons, I applied weak but regular doses of balanced fertilizer to promote their healthy growth. 

Maintain Warm Temperature And Humidity Levels. 

Peace lilies are native to the forest floor of tropical rainforests. There, peace lilies thrive in warm temperatures and high humidity. So, you should maintain a warm temperature and high humidity levels to mimic their native environments. 

Peace lilies prefer temperatures above 65 degrees Fahrenheit and aim for humidity levels above 50%.

Remainder: You should clean the leaves regularly to ensure they can photosynthesize effectively. You have to cut the yellow leaves and old flowers to encourage new growth and blooms. 

By following these steps, your peace lily can come back to life, and their growth will also increase.

Feeding Schedule Of Peace Lily To Enhance Growth

It’s crucial to know how to feed properly to enhance the growth of peace lilies. Because over fertilizing can be detrimental for your peace lily. 

On the contrary, if you don’t feed your peace lily, it can’t grow correctly. 

You can follow the feeding schedule to ensure proper growth of your peace lily.

The best type of soil for growing a Peace Lily is one that retains a little moisture but still drains well. Also it should be staying evenly damp without becoming soggy.

Now I will explore 3 best soil type that can help you grow peace lily:

  • Option 3: Use a ready-to-use potting mix formulated for aroids, such as a premium monstera potting, which works well for peace lilies. 

Peace lilies also prefer slightly acidic soil. They prefer pH level between 5.5 to 6.5. So, it’s also important to monitor the pH levels to ensure the soil is not too alkaline or acidic for optimal growth.

Peace lilies are susceptible to only a few diseases. Also Peace Lily plants can be affected by some pests including thrips, mealybugs, aphids, and spider mites. Fungus gnats are also common due to the high demand for water from this plant.
