As soon as people find out that I sell houseplants, I am usually asked the same handful of questions. One of those questions is almost always, “Can you help me save my Peace Lily?” (Or something along those lines.) So I figured I’d start my plant blogging journey with some help for all those Peace Lily parents out there. And since one of the most frequent questions I get about Peace Lilies is, “What type of soil should I use for my Peace Lily?” I figure that’s a great place to start. (Head to the very bottom of this article for the simple percentages of this potting mix recipe.)
One of the most important things to know about Spathiphyllum (that’s the scientific name of a Peace Lily) is that their root systems are very sensitive and can be burned by any potting mixes that have fertilizer already mixed in them. Now, I’m not saying that your plant will die if you use these types of potting mixes. They most likely won’t. But I will tell you that they will not be very happy and you will be running the risk of root damage and all the bad things that can follow. I don’t want your plant to be unhappy and most likely, you don’t either!
So let’s get to the recipe! You will need Coco Coir, Perlite, horticultural/Orchid Bark, horticultural Charcoal and Worm Castings. Yum! (I don’t know why, but as I typed the word “recipe” and then the words “Worm Castings” I just got this gag reflex thing going. Teehee.) I will include an affiliate link with each of these items in case you are interested in the specific brands that I use.
Begin with the Coco Coir. If you buy this in a block or brick, you will need to add water. It’s really cool like a science experiment! The Coir will absorb a LOT of water. Start with a small amount and you can add more as needed. The Coir will equal about 50% of the potting mix.
Next is the Perlite. This is an important step because the perlite will help prevent the coir from compacting around the roots of your plant. I generally add about 25% perlite. Is this an exact science? No. In fact I feel a little like a mad scientist when I am stirring up my potting mixes.
Orchid Bark comes next at about 15% of the mix. As you can assume from its name, orchid bark is used as a potting medium for orchids. We will be using it to add even more oxygen to the root zone of our Peace Lily. The bark pieces will trap oxygen near the root zone, they will prevent the potting mix from compacting around the roots and will also provide nutrients to the soil as the pieces of bark begin to break down.
Almost done! Next we will add approx. 5% horticultural Charcoal. Yes, it is important to use a charcoal product that is listed as horticultural. I add charcoal to my potting mixes when I know that the soil will be kept pretty moist. Charcoal works to remove impurities from the potting mix and also keeps it from smelling yucky.
Last, we will add in the Worm Castings at 5%. (In case you were wondering, worm castings is a nice way to say worm poopy.) Remember back in the first paragraph when I told you that Peace Lilies have roots that are sensitive to fertilizers? Well, worm castings are a gentle, yet effective way to give your plant a boost of nutrients. Also, I have found that some people are strongly opposed to using worm castings because they are essentially an animal byproduct. If you feel strongly against using worm castings, just leave that ingredient out of your potting mix. And yes, your potting mix recipe will only equal 95%.
Mix these ingredients well and you are all set to repot your beloved Peace Lily. If you would like to see this in a video format, click the link and it will take you to my YouTube video.
If you have read through this recipe and don’t feel like you can do this mix, let me recommend a potting mix that you can purchase ready-made. (Even though this potting mix is a really good one, I would still add more perlite. But that’s entirely up to you.) The Fox Farms Bush Doctor Coco Loco potting mix is a great choice. It uses coco coir as its base and not peat moss which is very important in my opinion.
I am aware that many of you who are looking for care tips for a Peace Lily are doing so because you have received this plant upon the death of a loved one. I want you to know that I take that knowledge very seriously, my friends! I do understand what a plant can do for someone who has lost a beloved family member or friend. I have used this mix for the last two years on my own plants with great success. I wish you all the best with your plant!
Mercy, peace and love be multiplied to you.
