Peace lily potting mix recipe

Whether you're growing a peace lily outdoors in your container garden or growing it as one of the best indoor flowering plants, you can make peace lily potting mix using this simple recipe.

Here's what you'll need:

• Pine bark
• Coco coir
• Perlite
• Horticultural charcoal
• Optional gravel or pebbles

'Start with putting some good horticultural charcoal (available at Amazon) in the bottom of the new pot your peace lily is getting potted into,' advises Alex Kantor, plant expert and Owner at Perfect Plants Nursery.

Cover the bottom inch of your pot with a layer of horticultural charcoal to add drainage and help keep mold and mildew at bay. Peace lilies are prone to houseplant root rot when overwatered, so it's important to create a well-draining mix.

To make the main potting medium, use around 80% pine bark as the base. Also good for orchid potting mix, this further aids aeration. At this stage, you can also add in 10% perlite to make the mix looser. 'You really cant go wrong here, adding in perlite makes the soil drain better,' Alex says.

You can then add 10% coco coir - a peat moss alternative - to help your peace lily retain enough moisture. Mix this in well with the bark and perlite to get an ideal mix.

Finally, once you have repot your peace lily in this DIY mix, you have the option to add a layer of gravel or pebbles - like these pea gravel pebbles from Amazon. This is an effective way to increase humidity for indoor plants, as the water on the pebbles transpires around the plant and creates a humid environment. Plus, it can look attractive in your houseplant display.

Why these are the best ingredients for peace lily potting mix

There are lots of ingredients you can use to make peace lily potting mix, but the ones included in our easy recipe are particularly beneficial for these indoor plants that flower all year round. Here's why:

'Peace lilies like water, but need to dry out between watering,' explains Alex. Perlite, pine bark and horticultural charcoal ensure your peace lily has sufficient drainage to do so. This can help stop your peace lily turning yellow.

Likewise, coco coir absorbs excessive moisture and releases it as its needed. This is a sustainable option to peat moss, too. Having these ingredients in place prevents issues like root rot and the build-up of mold and mildew.

Not only this, but using chunkier materials like pine bark and perlite also bring aeration to your peace lily pot and keep the mix quite loose. As a bonus, pine bark has plenty of essential plant nutrients to support peace lily growth.

Meanwhile horticultural charcoal helps repel common houseplant pests. It absorbs the odors and bacteria that often attract pests like fungus gnats. 'It's like a natural antiseptic,' says Anastasia Borisevich of Plantum.

These ingredients will also keep your plant happy after peace lily flowering and through its dormant season before a new flower stem starts to grow.

FAQs

What's the best pot for a peace lily?

Peace lilies need good drainage and therefore thrive best in pots with drainage holes. 'Make sure the container suits the size of the root system,' advises Anastasia. Growing a peace lily in a pot that is too small can lead to it becoming pot bound, causing problems like leaves on peace lily turning brown.
