☑ Natural, high-quality, earth-positive ingredients that enhance drainage, nutrient retention, and soil aeration to help your monstera plant thrive
☑ Clear of unsustainable materials like sphagnum peat moss (sphagnum moss), perlite, pumice, and coco coir!
☑ Reduces the need for synthetic fertilizers and their harmful effect on soil pH and microbes

Vegan Compost

Our vegan compost (aged compost) packs essential organic matter, aerates the soil, and improves drainage, so monstera roots get plenty of breathing space. 

The organic matter in our monstera potting mix also naturally boosts soil nutrients — you won’t have to use chemical fertilizers anymore!  

Carbon-Negative Biochar

Meet the star of our indoor potting mix! Biochar is a carbon-negative soil amendment that enhances soil activity. 

It works by improving soil drainage, nutrient and moisture retention — critical for a healthy monstera plant. It also promotes healthy root development for your monstera plant. 

What’s more?

For each ton of biochar produced, three tons of CO2 is removed from the carbon cycle. 

This makes it the perfect alternative to unsustainable ingredients like sphagnum peat moss, coco coir, vermiculite, and perlite.

Root Boosting Mycorrhizae

Mycorrhizae (mahy-kuh-rahy-zee) are plant-friendly fungi that mesh with the plant’s roots to form a mutually beneficial relationship with the monstera plant. 

It helps the roots of your indoor plants access water and nutrients better. And during this process, the fungi release a gum-like substance called glomalin that further locks in moisture

Step 1: Pre-Moisten

It’s best to moisten Rosy before adding it to your pots. 

Add this monstera soil to a container and sprinkle it with water until it holds enough to release a few drops when squeezed. 

Step 2: Pot or re-pot

Fill a well-draining pot with 1/3 pre-moistened Rosy. 

Step 3: Plant

Gently release your monstera plant from its current container.

Then, loosen the root system before centering the plant into the new pot and fill the remaining space with Rosy. 

Remember to leave an inch at the top to easily water monstera.

Step 4: Water

Water monstera soil slowly until the excess water drains from the bottom. 

For future watering, we recommend bottom watering since biochar can retain water for a long time. Occasionally, you can perform top watering to flush the soil.

Ensure the pot has a proper drainage hole so that excess water can drain out.

From manufacturing our potting mix to transporting it to your home, our entire supply chain has a net negative carbon footprint

You heard that right! The Rosy Monstera Soil Mix captures over 2 kg of CO2 from the carbon cycle. This is possible because of sustainable shipping, packaging, and carbon-negative ingredients, especially biochar.

About Monstera Soil & Care

Monstera is a big-leafed aroid plant (often confused with philodendron) native to South America, where it vines up to 30 feet. It attaches itself to the trees using its aerial root. 

This tropical plant comes in various varieties, including:

  • Monstera deliciosa (Swiss Cheese plant)
  • Rhaphidophora tetrasperma (mini monstera)
  • Monstera adansonii
  • Monstera acacoyaguensis
  • Monstera acuminata
  • Variegated Monstera deliciosa plant like Thai constellation or mint monstera 

How to grow a monstera plant?

Growing monstera is quite simple. 

All you need are healthy cuttings (preferably with a new leaf sprouting from it), a favorable environment, and the best soil mix. 

As an indoor plant, monstera grows best in ample indirect sunlight and aerated, well draining soil. The growing season for this houseplant is from spring through fall.

Here’s everything else you need to know about growing monstera — from the perfect monstera soil to plant care:

1. Characteristics of Monstera Soil

The best soil for monstera has the following characteristics:

  • Monstera needs nutrient-rich potting soil that mimics tropical soil, which is continuously fed by biodegradable plants and animal droppings. It’s also well-aerated by the lively microbial activity.
  • The plant doesn’t like “wet feet.” So, you must ensure that your potting soil has good drainage and aeration to prevent water logging.
  • Even though the monstera plant needs well-drained potting soil, it also needs plenty of moisture that imitates the high humidity of its natural habitat. So, ensure your potting soil has good moisture retention.

2. Monstera Soil Ingredients

Monstera potting soil usually contains ingredients like biochar that help with nutrient and water retention. 

Biochar also improves soil drainage, preventing root rot — which can cause brown spots on monstera leaves. It’s also carbon negative, making it a great alternative to unsustainable materials like peat moss, coco coir, and perlite.

The growing medium should also contain compost that provides this tropical plant with the necessary nutrients.

On top of that, a monstera potting soil mix may contain pine bark or orchid bark chips and sand for better aeration.

Note: Unlike Rosy’s soil mix, most traditional indoor plant mixes are sterilized with chemicals, which may not be good for your plant in the long run. 

3. Monstera Plant Care

Here are some pro tips to take care of your indoor plant:

  • Avoid direct sunlight as it can scorch monstera leaves.
  • To provide ample moisture, water your Swiss cheese plant (or any other variety) when the top 2-3 inches of soil is dry. Dry soil can give rise to spider mite, which can suck out the sap from the leaf. 
  • Avoid overwatering your houseplant, which may cause root rot or fungus gnats. Too much water will also hinder oxygen and nutrient supply, which can cause the leaf of your houseplant to turn yellow.
  • Use a moss pole for this potted plant so its aerial root system has something to hold onto. 
  • Monstera doesn’t require frequent repotting — once every two years should do the trick.

The best soil I've ever used

Such good quality soil. You can see and feel the difference from store bought. The only complaint I have is its super small quantities. When I bought the 8 quart it only took care of 2 plants. This soil makes me feel like a good plant mom :)

My plants love it!

I’m really happy with this soil mix. I repotted four plants with this mix 2 months ago and my plants are very happy. My monstera has grown 6 new leaves sine repotting. I did major surgery on my jade and it has put out so many new little leaves. I do pick out little mushrooms often but it doesn’t bother me. Will be purchasing again.

Interesting soil seems great.

I’ve transplanted all that I could for about 3 weeks now and all of the plants appear very happy. I enjoyed working with it also. I would definitely plant more of my plants in the soil.

Grew a new leaf!

I planted some cuttings from a plant I dropped. At first I was a little apprehensive because the soil is really dark lol….but after 3 weeks she seems to be doing great. She even grew a new leaf 🤗.
