But as a new plant parent, I didn’t know how often should I spray my peace lily.

One day, I noticed the leaves of the plant were looking wilty and droopy. Also, my Peace lily became more susceptible to pests and diseases.

Then I found these are happening due to lack of humidity.

Spray Peace Lily

In this guide, I will share how much you should spray on your plants when I explore tips for spraying frequency.

What Should I Spray My Peace Lily?

I know that peace lilies don’t need too much care. But I didn’t know that they need some attention to grow well and bloom properly. 

They have some requirements like light, temperature, humidity, soil quality, etc. Adequate sunlight for peace lily plant is needed for their growth. 

While they can thrive in low light conditions, they prefer bright, indirect light and high humidity. 

When I faced some issues, I thought do peace lilies like to be sprayed?

Because Peace lilies are tropical plants. They are mainly native to the tropical region of the Americas and Southeast Asia. So they need to be sprayed to maintain their environment. 

But the query is, what should I spray?

After some research, I found, that I can spray many things based on their need, such as :

  • Water
  • Insecticidal soap
  • Neem oil
  • Mild Liquid Fertilizer
  • Diluted milk


It’s necessary to keep a balanced humidity level for peace lily. Misting its leaves with water can help replicate the humid environment of tropical rainforests. 

Distilled water or rainwater is best for spraying on peace lilies. Don’t use tap water. It may contain chlorine or other chemicals that can harm your plant.  

Insecticidal Soap

If you notice any pests like spider mites or aphids on your peace lily, you can use insecticidal soap. Make sure to spray both the upper and lower surfaces of the leaves. 

Neem Oil

Neem oil is a best natural insecticide and fungicide. You have to mix neem oil with water according to the instructions on the product and spray it on your peace lily. 

Mild Liquid Fertilizer

During the growing season, like Spring and Summer, you can spray balanced liquid fertilizer. A balanced liquid fertilizer contains nitrogen, potassium, calcium, and other necessary elements. It provides adequate nutrients to your peace lily. Eggshells for peace lily can be used as an alternative to calcium.

Diluted Milk

One day I also used a mixture of water and milk (1 part milk to 9 parts water) as a foliar spray to help prevent powdery mildew on plants. 

Note:  Test any spray on a small, inconspicuous area before using the hole plant. So you can ensure it doesn’t have an adverse reaction.

When Spay Liquid Fertilizers

Well, the frequency of use of liquid fertilizer depends on several factors like type of fertilizer, plant growth stages, and environmental conditions.

Spraying frequency is the number of times a liquid is sprayed over a certain period of time. 

However, various factors influence the spraying frequency of peace lily. 

Some common factors are plant type, growing season, environmental conditions, Soil condition, Pest or disease severity, and fertilizer type. 

Let’s understand, how they influence praying frequency:

  • Growing season: Plants have different growth patterns during various seasons. You should do it more frequently during their growing seasons and less in dormant periods. 
  • Environmental condition: Environments have a great influence on spraying frequency. For example, the temperature and humidity levels of America and London are different. Peace lilies like high humidity levels. So if your your room humidity is low then you have to spray more frequently. 
  • Soil condition: The health of the soil can also affect this process. Excess water can harm your plant. It can lead to root rot. So, you shouldn’t spray when they have enough water in the soil. Excess  
  • Pest or disease severity: The presence of pests or diseases can influence the frequency of spraying. If plants are affected by infestation, more frequent application may be necessary initially.
