Vegan Compost

Our plant-based aged compost creates a thriving environment for growing syngonium indoor plants.


It offers abundant organic matter, promotes drainage, and enhances soil structure. 

It also provides a natural source of vital nutrients, reducing your reliance on a chemical fertilizer that harms beneficial microbes and decreases soil pH. 

Carbon-Negative Biochar

Biochar is the star ingredient in Rosy’s syngonium soil mix. 

This lightweight, porous, and Earth Positive substance keeps the soil fertile for longer by enhancing nutrient retention, soil aeration, and drainage. 

What’s more? 

Every ton of biochar produced eliminates three tons of CO2 from the carbon cycle. This makes it the perfect alternative to unsustainable soil additives like perlite, coco coir, or vermiculite.

Root Boosting Mycorrhizae

Rosy’s syngonium potting mix includes root-fortifying fungi — mycorrhizae (mahy-kuh-rahy-zee). 

These plant-friendly fungi form a symbiotic relationship with syngonium plant roots, improving nutrient retention and tolerance to drought and pests. 

They also release a gum-like substance called glomalin, which helps retain moisture and nutrients.

Step 1: Pre-Moisten

Rosy’s syngonium soil works best when moistened before use.

Place the soil in a container and water it until it releases a few drops when pressed. 

Step 2: Pot or repot

Choose a pot with drainage holes and fill it up ⅓ with the pre-moistened syngonium potting soil. 

Step 3: Plant

Take your syngonium (arrowhead vine) plant out of its current pot, ensuring you don’t disturb the root system. 

Center the plant in the new pot and add more Rosy potting soil, leaving an inch at the top for watering. 

Step 4: Water

For the first watering, water your potted syngonium plant from the top, allowing the excess water to drain. 

For future instances, we suggest bottom watering your plant by placing your pot or container in a tray filled with water. Occasionally water from the top to flush excess salts and minerals from the soil. 

Rosy maintains a net negative carbon footprint — from manufacturing to transporting our syngonium soil mix to your home.

Wait, it gets better! 

Our soil captures over 2 kg of CO2 from the carbon cycle — thanks to sustainable packaging, shipping, and carbon-negative ingredients like biochar.

Syngonium Soil & Plant Care Guide

Syngonium (arrowhead plant or arrowhead vine) is native to the rainforests of Central and South America (Mexico, Brazil, and the West Indies). 

Growers love this Araceae species for its gorgeous variegation, foliage, and aerial root system, often keeping syngonium varieties like: 

  • Syngonium podophyllum (arrowhead philodendron, white butterfly, nephthytis, goosefoot)
  • Syngonium podophyllum albo variegatum (syngonium albo)
  • Syngonium podophyllum neon robusta (syngonium neon robusta)
  • Syngonium pink splash (pink syngonium)

What do you need to grow these indoor plants?

Let’s explore syngonium soil, plant care, and propagation tips. 

1. Best Soil for Growing Syngonium

To thrive, your arrowhead plant needs a: 

  • Nutrient-rich soil rich for growth and development. 
  • Well-draining potting mix with good drainage and moderate moisture retention. Overly moist soil can cause root rot. 
  • Aerated soil mix to let the roots breathe. Ideally, select soil with amendments like compost, biochar, or orchid bark.

Rosy’s syngonium soil meets all the above requirements, plus it’s sustainable!

2. Essential Syngonium Care For a Thriving Houseplant

Follow these simple arrowhead plant care tips: 

  • The tropical plant prefers medium to low light conditions since the direct sun can cause leaf burn. Like a monstera, it thrives under:
    • Partial shade — bright indirect light (not direct sunlight)
    • Early morning bright light (bright indirect sunlight) 
    • Indoor plant lighting (grow lights) 
  • These indoor plants love temperatures between 60-80℉. Ideally, keep syngoniums away from windows during winter.
  • Like other houseplant care practices, water your syngonium when the soil’s top 1-2 inches feel dry. 
  • Yellow leaves or a green leaf turning yellow may signify dehydration. Conversely, overwatering will cause root rot.
  • The ideal humidity level for your indoor plant is 40-60%. If the humidity is low, use a humidifier (instead of misting) to maintain high humidity levels.
  • Add fertilizer, like worm casting or organic liquid fertilizer, monthly during the growing season (spring to fall). Avoid fertilizing, whether organic or liquid fertilizer, in winter.
  • Clean the houseplant leaves with a moist cloth every few weeks to keep pests like spider mites and mealybugs away. 
  • Use a moss pole to direct the aerial root system of your vining plant.
  • Repot during the growing season if the plant’s root-bound.

Note: Syngonium cultivars contain calcium oxalate in their foliage — which is toxic if ingested by pets or humans.

3. Syngonium Propagation Tips

Like aroids, syngonium propagation is easy with mature plants. 

How to propagate syngoniums?

  • Take stem cuttings from your plant. Ensure each cutting has a green leaf or two and a couple of leaf nodes. 
  • If propagating in water, submerge one-third of the cutting.
  • If propagating in soil, dip the cutting in a rooting hormone like honey before planting in moist soil like Rosy’s. 
  • Place the container in bright indirect light or indirect sunlight to see new growth and new leaves in a week or two.

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 🤗.
