Regular price$19.99

☑ Nutrient-rich hoya potting soil with earth-positive ingredients (no peat moss, coco coir, perlite, pumice, or vermiculite!)
☑ Boosts soil aeration to enable easy oxygen access for the plant’s root system
☑ Optimizes water drainage to create the perfect environment for hoya plant growth

Carbon-Negative Biochar

Meet the cornerstone of our soil mix: biochar

It’s a lightweight and porous substance that improves soil aeration and drainage. It also enhances nutrient retention, keeping your soil fertile for longer. 

What’s even better?

Each ton of biochar produced traps three tons of CO2 from the carbon cycle! 

This makes our soil mix an Earth Positive potting medium — unlike a conventional hoya mix with unsustainable ingredients like sphagnum moss, coco coir, pumice, or perlite.

Vegan Compost

Your hoya houseplant will love our aged, vegan compost

Here’s why:

It adds abundant organic matter, improves soil structure, and optimizes drainage.

Our compost is a natural source of vital plant nutrients, like nitrogen and potassium. This, in turn, reduces the need for chemical fertilizers. 

It creates the right environment for beneficial microbes.

Root Boosting Mycorrhizae

Mycorrhizae (mahy-kuh-rahy-zee) are naturally occurring plant-friendly fungi that improve water and nutrient access for your indoor plant.

They also release a substance called glomalin to lock in moisture and nutrients, helping your hoya plant tide over short periods of water stress.

Step 1: Pre-Moisten

For the best results, pre-moisten your Rosy hoya soil mix before planting your hoya.

Add the soil mix to a container and water it until the soil releases a few drops when squeezed. 

Step 2: Pot or repot

Fill up 1/3 of a well-draining container with the pre-moistened soil mixture. 

Step 3: Plant

Gently release your indoor plant from its current soil while ensuring you don’t disturb the root system. 

Then, center the plant into the container with Rosy hoya soil mix.

Finally, fill the remaining space with more pre-moistened soil, only leaving an inch at the top for easy watering. 

Step 4: Water

For the first watering, water from the top till the excess drains out of the container. 

For future waterings, we suggest bottom watering (place the pot or container in a tray with water). This allows the soil to absorb water evenly.

Occasionally, top water the soil to flush salt deposits.  

When we consider our entire supply chain, the Rosy hoya soil mix has a net negative carbon footprint!

How did we manage that?

We maintain an earth-positive system (from production to delivery) by curating the most sustainable ingredients (like biochar), packaging and shipping processes.

In fact, every bag of Rosy soil traps more than 2 kg of CO2 from the carbon cycle!  

This makes our hoya potting mix a positive resource for your indoor garden and the environment.

Hoya Soil Mix and Plant Care Guide

Hoya is a tropical plant commonly known as a wax plant or honey plant. 

Loved for their fragrant flowers and stunning foliage, hoyas come in various species, like:

  • Hoya carnosa (most common wax plant variety)
  • Hoya obovata
  • Hoya kerrii (sweetheart hoya)
  • Hoya Acuta Variegata (variegated hoya)
  • Hoya linearis
  • Hoya pubicalyx 

The species requires minimal care and thrives in indirect light, making it a hot favorite among indoor gardeners.

But what’s the right soil for hoya? 

When should I water it? 

How do I propagate my hoya plant?

You have the questions. We have the answers. 

1. Choose the Best Soil for Hoya

In nature, most hoyas grow on trees like epiphytes (think: orchid). 

Indoors, this tropical plant can survive in soil with:

  • Good aeration: A hoya plant’s root system requires proper access to oxygen. Aeration also prevents soil compaction (a common problem in DIY mixes with sphagnum moss).
  • Optimal drainage: Hoya plants need slightly moist soil that’s also well-draining to avoid root rot. Ingredients like compost, biochar, horticultural charcoal, pine bark, or orchid bark can help here.
  • Ample nutrients: Like any other houseplant soil, your hoya mix should contain essential nutrients, like nitrogen and phosphorus, to support plant growth. 

So can I use a cactus mix?

You could use succulent soil, orchid mix, or African violet potting soil as a hoya soil mix. 

But we recommend using soil specifically crafted for hoyas — like Rosy’s hoya soil.   

2. Hoya Plant Care Tips

Do you ask yourself: “How can I help my hoya flourish?

Then apart from choosing the best soil, follow these essential plant care tips:

    • Provide bright indirect sunlight: Like philodendrons and monsteras, hoya plants need ample indirect light. Direct sunlight can burn your wax leaf plant.
    • Adjust your watering schedule: Water your hoya mix only when the top layer dries, but reduce the watering frequency in winter. You can also use a humidifier to maintain optimal humidity, but ensure this doesn’t lead to overwatering — which causes root rot.
    • Add fertilizer: During its growing season (spring and summer), fertilize your waxy leaf plant once a month. Use worm castings, compost, or fertilizers rich in phosphorus to encourage blooms.
    • Use an appropriate pot: Terracotta containers are better for hoyas since they are very porous. Regardless, the container should be up to 2 inches larger than the root ball and have a drainage hole.
    • Provide support: Use hanging baskets or a trellis for vining foliage or epiphytic (orchid) hoya varieties.
    • Repot your hoya plant once every few years: Use fresh soil but don’t change the container size (since hoyas like to be root bound). Also, avoid disturbing the roots when repotting.
    • Use a cutting to propagate hoya: Place a stem cutting with a leaf or two to root in water or soil during its growing season. If you use water, move the cutting to a potting medium when the roots grow 2 inches or more.

It’s good a little pricey

So I wanted to try it and I really like it. I hope the price comes down in the future because it is on the pricey side. I think it’s fine if you have just a couple of plants but u have over 60 so it gets pricey!

Plants are thriving.

I've been using ROSY soil for a little over a year now, and my plants have never been happier. I've noticed a significant improvement in the overall health of my pothos, with extremely fast growth. It's very easy to work with and provides everything your plant needs to thrive. I was able to use the abundance of growth to propagate more healthy pothos plants - all potted in ROSY. I would recommend this to any plant parent!
