☑ Potting soil for herbs that contains good quality, all-natural ingredients (no perlite, coconut coir, vermiculite, or sphagnum peat moss)
☑ Boosts drainage and moisture retention — must-haves for container gardening
☑ The best potting soil mix for a beautiful herb garden

Vegan Compost

Our aged compost is plant-based and creates a lush environment for your herbs. It offers ample organic matter, boosts soil structure, and enhances drainage.

It’s also a natural source of essential nutrients for perennial herbs. So, you’ll reduce your reliance on synthetic fertilizers that can harm microbes and decrease the soil pH.

Carbon-Negative Biochar

Biochar is the core of our potting soil. It enhances the growth of herbs by supporting their root development and increasing water and nutrient retention.

Plus, it helps trap atmospheric carbon dioxide! Three tons of carbon dioxide are removed from the carbon cycle for every ton of biochar generated.

This makes Rosy’s soil an excellent alternative to traditional herb soils (which contain unsustainable amendments like coco coir and sphagnum peat moss).  

Root Boosting Mycorrhizae

Mycorrhizae (mahy-kuh-rahy-zee) are herb-friendly fungi that enhance your potted herbs’ ability to retain water and essential nutrients. 

They help your houseplant thrive by bonding with its root system. The fungi also release glomalin, a gum-like substance that further locks in nutrients and moisture.

Step 1: Pre-Moisten

Rosy does best when it's pre-moistened before being added to pots. Moisten it with a bit of water until it holds enough to release a few drops when pressed.

Step 2: Pot or re-pot

Get a pot or herb container with suitable drainage and fill it up 1/3 with moist soil. You can also use a raised bed with proper drainage.

Step 3: Plant your herb

Carefully release your herb from its current soil mix and gently remove any debris lodged in the roots.

Spread out the root ball a little before centering the growing herb into your pot. Then, fill the pot with more moist soil, but leave about an inch at the top for watering.

Step 4: Water your herb garden

Water your potted herb plant gently, allowing the excess water to drain from the bottom. 

For the next watering, we recommend bottom watering (by placing the pot in a container/tray of water). 

This lets you water the soil without drenching the growing herbs' leaves. It also moistens the potting mix more consistently and nourishes the roots during the growing season.

You can periodically water from the top to flush out accumulated mineral and salt deposits in the soil.  

Rosy maintains exceptionally eco-friendly processes. And one of the most exciting parts is that our entire supply chain has a net negative carbon footprint!

Our Rosy soil for herbs captures over 2kg of CO2 from the carbon cycle.


We intentionally use the most sustainable carbon-negative ingredients (like biochar), packaging, and shipping.

Herb Soil & Care

Annual herbs (basil, cilantro, fennel) and perennial herb plants (oregano, marjoram, chives) are popular among growers. 


Growing herbs is more economical than buying them at the store. Plus, you can easily set up a thriving herb garden with the right growing conditions. 

You can:

  • Grow your herbs indoors or outdoors, depending on the weather, and enjoy your potted plant year-round.
  • Place your potted herb on your kitchen windowsill to keep it accessible when cooking. 

Let’s now explore the best potting soil and care tips for growing fresh herb plants:

1. The Best Potting Soil for Herbs

Your herb plant won’t flourish without the right potting mix.

Here’s what to consider when selecting the best type of  soil for herbs:

  • Nutrient-Dense: The best soil must have a mix of organic matter and essential nutrients since herbs need adequate plant food to flourish. 
  • Optimal Drainage: The potting soil should retain moisture and drain well. Your container should also have good drainage holes to release excess water.
    Well drained soil (like loamy soil) is essential to avoid root rot, which is common among indoor herb plants. On the other hand, your culinary herbs can start wilting in gritty alkaline chalk and sandy soil or dense clay soil.
  • Well-Aerated: The best soil for herbs should be light and fluffy. This creates air pockets in the potting soil, giving the indoor plant roots easy access to oxygen. 

2. How To Grow A Herb Plant 

Growing a herb from seed can take time since germination (seed starting) needs a suitable environment. 

Instead, to grow annual herbs and perennial herbs quickly, you could get a starter plant or take a cutting to grow your herbs indoors or in an outdoor container.

Here’s how you take a cutting for a potted plant:

  1. Find an outward leaf node on a green stem and make an angled cut above it. 
  2. Remove the leaves from the lower part and plant the stem in moist soil.
  3. Pop a plastic bag on top of it to provide some humidity.
  4. Water your fresh herb and check for new leaf growth every few weeks.
  5. Re-pot the herb into a larger container with potting soil.
  6. Gradually introduce the herb to direct sunlight (herbs can flourish with full sun exposure and partial shade).

3. Caring For Your Culinary Herbs

Love vegetable gardening? 

Try these care tips for your favorite herb plant (including Mediterranean herbs):

  • Avoid planting herbs in garden soil. Instead, opt for well drained soil.
  • Water your herb plant only when the 1-2 inches of the top soil is dry to avoid overwatering.
  • Add plant food (like worm castings) to the soil mix every 3-6 months, starting from the growing season.
  • Increase yield by pruning your indoor herb plant when it grows about 3” above the soil.
  • Perennial herb flowers can turn a sweet basil bitter, but if you’re regular with your trimmings, this shouldn’t pose a problem.

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.
