Vegan Compost

We use aged and plant-based compost to provide essential plant nutrients (like nitrogen and phosphorus) for your calathea plant. 

The organic matter in the compost also helps with aeration, drainage, and preventing root rot.

Plus, it minimizes the need for synthetic fertilizers — which can harm soil microbes and pH levels when used excessively.

Carbon-Negative Biochar

Biochar is the star of Rosy’s calathea potting mix! It enhances aeration, drainage, nutrient retention, and plant root development.

What’s more?

Biochar is carbon negative. 

For every ton of biochar produced, three tons of carbon is removed from the emission cycle.

That’s why it’s a better alternative to activated charcoal and unsustainable soil additives like peat moss, pumice, and coco coir.

Root Boosting Mycorrhizae

Rosy’s calathea soil contains plant-friendly fungi known as mycorrhizae (mahy-kuh-rahy-zee). 

The benefits?

The fungi enhance water and nutrient access for the plant’s root system.

They also create glomalin, a gum-like substance that further locks in the moisture and nutrients calathea plants need.

Step 1: Pre-Moisten

We recommend moistening Rosy’s calathea soil before use for the best results.

Place your desired amount of the potting soil in a container and spray with water until it releases a few drops when pressed.

Step 2: Pot or repot

Choose a pot with drainage holes (on the side or underside) and fill it 1/3 with pre-moistened Rosy potting soil.

Step 3: Plant

Release your calathea from its current container and remove any soil debris around the plant’s roots.

Next, center the plant in your new pot and fill the remaining space with pre-moistened Rosy soil. Leave an inch of space at the top for easy watering.

Step 4: Water

For the first watering, water your calathea from the top and allow the excess water to drain.

For future watering, we recommend bottom watering. You can water from the top occasionally to flush excess salts and minerals.

Rosy’s entire supply chain has a net negative carbon footprint — from manufacturing to delivery.

How do we do this?

We carefully select the most sustainable packaging and shipping options. Plus, we use low-carbon and carbon-negative ingredients (like biochar) for our potting mix.

In fact, each bag of Rosy soil captures 2 kg of CO2 from the carbon emissions cycle!

Calathea Soil & Plant Care Guide

Calathea houseplants are beautiful plants with colorful, sometimes variegated leaves.

This tropical plant genus includes many gorgeous calathea varieties, like:

  • Calathea ornata (Pinstripe calathea or Pinstripe plant)
  • Calathea orbifolia (Prayer plant or Maranta)
  • Calathea rufibarba (Furry feather calathea or Velvet calathea)
  • Calathea lancifolia (Rattlesnake calathea or Rattlesnake plant)
  • Calathea roseopicta (Rose painted calathea or Calathea dottie)
  • Calathea makoyana (Peacock plant)
  • Calathea zebrina (Zebra plant)
  • Calathea lietzei (Calathea white fusion)
  • Calathea veitchiana (Calathea medallion)
  • The kicker?

    Calatheas have specific requirements growers must meet, like moist soil, distilled water, high humidity, and indirect sunlight.

    Here are some calathea care tips for growing this fussy houseplant:

    1. Choosing the Best Soil for Calatheas

    Calathea soil should have:

    • Plenty of aeration, so the root system has space to develop. 
    • Good drainage to prevent root rot and wilting. However, there should be sufficient moisture retention to keep the soil moist and provide enough water for the plant.
    • High nutrient content to encourage new growth.

    Moreover, choosing a calathea soil mix with sustainable amendments (biochar, worm castings, orchid bark, etc.) is best. Avoid mixes with unsustainable additives like perlite, peat moss, coconut coir, and vermiculite.

    We recommend: 

    A well-draining soil mix like Rosy’s calathea soil. It has everything your calathea plant needs, and it’s eco-friendly.

    2. Providing the Perfect Lighting for Calatheas

    Keep your calathea houseplants in a spot with low to bright indirect light — they prefer low-light conditions and do poorly in direct sunlight. 

    How do you know if your calathea needs low or bright indirect light?

    Check the color of the calathea leaves:

    • Calathea varieties with darker leaves prefer minimal indirect light or deep shade.
    • Brighter green, rosy, or purple calathea leaves can thrive with medium to bright indirect sunlight (but not direct sunlight).

    3. Watering Calathea

    Follow our handy tips when watering calatheas:

    • Calathea plants enjoy moist soil, so water them when the top 1-2 inches feel dry. This will help you avoid underwatering and overwatering your calathea.
    • Use a pot with drainage holes so the excess water can flow out. 
    • Tap water could cause brown leaf tips on your calathea indoor plant. To resolve this, dechlorinate your tap water by letting it sit overnight. Alternatively, use distilled water. 

    Did you know the plant’s pot affects moisture retention?

    An unglazed terracotta pot can wick away water, causing moist soil to dry faster — this can help if you tend to overwater. But if you want to keep the soil moist, use a different type of pot.

    4. Creating a Humid Environment for Calathea

    Since it’s a tropical plant, calathea plant care requires warmth and humidity. It may develop brown leaf edges when kept in low humidity.

    How can you improve humidity?

    Use a humidifier or terrarium to create high humidity levels for your calathea.

    Create beautiful plants!!

    This potty mix is different than anything I’ve ever used. I haven’t had to add to the soil. I’m able to use the soil as it comes. Seems like it’s highly nutritious. I have half my plants potted in it. I plan to pot the rest of them in the same soil!

    Highly recommend! So far so good!

    Only thing that I noticed it didn’t expect was that when I watered the water will run black. So don’t walk a drippy plant across the house. 🙄

    Nice soil. Super dark and nutritious looking. A bit on the expensive side, so I'm not sure I'll keep purchasing the houseplant one , but definitely buy more of the cactus blend.

    Wear gloves lest you look like a Victorian orphan

    I got this soil to try to revive a very sad plant in my house. I was previously using a *miraculous growing soil* but I didn’t feel like it kept moisture as well as I wanted. What I really like about this mixture is the texture. It feels almost like sand, it’s fine and soft and absolute black. Which is only relevant if you don’t wear gloves while potting…………… I didn’t feel like I was fighting all the pieces of bark and mulch normally found in these houseplant mixtures, which made planting a bit easier in my pots (they’re long and skinny so there’s plenty of space for roots but not for hands messing around). This bag filled one 14x3x4” pot (nearly to the top) and a 10x3x6” pot (shallow). If you’re conservative with soil then I’d say its A decent size for the price, but if you are on a budget or have an entire greenhouse of plants then the cost isn’t sustainable. The packaging is nice, I truly appreciate that it is resealable. Pouring was easy when the soil was dry, but I decided to pre-moisten the second batch in the bag since I knew I was going to use it up and it got all stuck up in the zipper flap. A negligible complaint, I think. It’s been a few days since I repotted and the jury is still out if it can revive my severely neglected pothos, but so far it’s looking good. I don’t see any signs of shock and the moisture seems to be keeping. Overall I think it’s worth a shot, even at the higher price point.
