The Best Soil for a Peace Lily: A Gardening Guide

Getting the soil conditions right is key to keeping peace lily happy and healthy indoors. Peace lilies are sensitive to very wet, dense soil that doesn’t drain properly. But their roots also dislike completely arid soil. The sweet spot is a lightweight, acid moisture-retentive potting mix. In this article, I will cover the best soil for a peace lily plant and some recommended mixes that you can prepare at home. Also, I include some tips when repoting and creating the ideal soil base. Proper soil goes a long way in growing vibrant peace lilies that will bless your home with their lush greenery for years on end.

What is the Best Soil for a Peace Lily?

After caring for peace lilies over the years, I’ve learned the soil they grow in is pivotal for lush, healthy plants. In this section, I will discuss the best soil for a peace lily, including its drainage, moisture retention, nutrients, and soil acidity.


The peace lily requires well-draining soil to prevent water from accumulating around its roots. A soil mix that includes perlite or sand can improve drainage. Additionally, adding a layer of gravel or rocks to the bottom of the pot can help excess water drain away from the roots.

Moisture Retention

While the peace lily requires well-draining soil, it also needs soil that can retain moisture. A soil mix that includes peat moss or coconut coir can improve moisture retention. It is important to ensure that the soil remains moist but not waterlogged, as this can lead to root rot.


Getting the right combo of vital nutrients is imperative for a peace lily to fully flourish. A soil mix that includes organic matter, such as compost or worm castings, can provide the necessary nutrients. Alternatively, a balanced slow-release fertilizer can be added to the soil mix.

Soil Acidity

For optimal growth, peace lilies thrive best in somewhat acidic soil conditions, around pH 5.5-6.5. A soil mix that includes sphagnum peat moss can help to maintain the desired acidity level. It is important to avoid using soil mixes that are too alkaline, as this can lead to nutrient deficiencies. Learn more about how to measure soil pH.

To summarize, the best soil for a peace lily should have good drainage, moisture retention, and a balanced mix of nutrients. It should also be slightly acidic, with a pH range of 5.5 to 6.5. By providing the peace lily with the right soil conditions, it can thrive and produce beautiful blooms.

Potting Mix Options

When it comes to choosing the best soil for your peace lily, there are several options to consider. Here are some of the most popular potting mixes for peace lilies:

1. Peat-based mix

Peat-based mixes are made from sphagnum peat moss, which is a common ingredient in many potting soils. This type of mix is lightweight and has good water-holding capacity. However, it is essential to note that peat-based mixes can become compacted over time, which can lead to poor drainage and root rot.

2. Perlite mix

Perlite is a lightweight, volcanic glass that is used in potting mixes to improve drainage. Perlite mixes are a good choice for peace lilies because they provide excellent aeration and drainage.

3. Vermiculite mix

Vermiculite is a mineral that is used in potting mixes to improve water retention. Vermiculite mixes are a good choice for peace lilies because they hold moisture well and provide good aeration.

4. Compost mix

Compost mixes are made from a blend of organic materials, such as composted bark, peat moss, and perlite. This type of mix is a good choice for peace lilies because it provides nutrients and improves soil structure. However, it is essential to use a high-quality compost that is free from pathogens and weed seeds.

Repotting Tips

When it comes to repotting your peace lily, there are a few things to keep in mind to ensure the plant stays healthy and happy.

Firstly, it’s important to choose the right soil. A well-draining soil mix that retains moisture is ideal for peace lilies. Avoid using heavy, clay soils that can suffocate the roots and cause waterlogging.

Before repotting, make sure to water the plant thoroughly to help it adjust to the new soil. Gently remove the plant from its current pot, being careful not to damage the roots. If the roots are tightly packed, consider loosening them to promote healthy growth.

Choose a new pot larger than the current one. Fill the bottom of the pot with a layer of soil, then place the plant in the center and fill in around it with more soil.

To help retain moisture, consider adding a layer of mulch on top of the soil. This can also help prevent weeds from growing.

Finally, water the plant again and place it in a bright, indirect light location. Avoid direct sunlight, as this can scorch the leaves.

In summary, these are the repotting tips you should follow:

  • Choose the right soil mix
  • Water the plant before repotting
  • Gently remove the plant from its current pot
  • Loosen tightly packed roots
  • Choose a slightly larger pot
  • Add a layer of mulch
  • Water the plant again after repotting
