☑ Aids moisture control and stimulates plant growth
☑ The best soil for flowering plants

Vegan Compost

Our aged and plant-based compost provides abundant organic material and supports moisture retention and drainage.

Even better?

It’s packed with vital plant nutrients for perennial and annual flowers. 

So this organic fertilizer reduces the need for synthetic fertilizer, which can negatively impact soil pH levels and microbes.

Carbon-Negative Biochar

Meet the star ingredient of our soil mix: Biochar

This sustainable soil amendment enhances nutrient and moisture retention in the soil, stimulating plant growth.

What makes biochar sustainable?

For every ton of biochar produced, three tons of CO2 are captured!

Bottom line: Rosy’s soil for flowers is an excellent alternative to a garden center soil mix containing unsustainable additives like peat moss (sphagnum moss) and perlite.

Root Boosting Mycorrhizae

Mycorrhizae (mahy-kuh-rahy-zee) are plant-friendly fungi forming mutually beneficial bonds with plant roots.

The benefit?

Mycorrhizae form a filamentous structure (a secondary root system), allowing indoor plants and flowering plants to absorb more water and plant food.

They produce a gum-like substance, glomalin, which further locks in moisture and nutrients.

Step 1: Pre-Moisten

We recommend moistening Rosy’s soil for flowers before use. 

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

Step 2: Pot or re-pot

Choose a container with drainage holes and fill 1/3 with the pre-moistened Rosy potting mix. 

You can use Rosy for a container garden, raised bed, or potted houseplant.

Step 3: Plant

Gently take your plants out of their current container, removing any debris around the plant roots.

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

Step 4: Water

Water your plants from the top for the first watering, allowing the excess water to drain from the bottom. 

For future waterings, we recommend bottom watering to keep the soil evenly moist. You can do an occasional top watering to flush the soil of any salt and mineral build-up.

Rosy’s entire process, from manufacturing to delivery, has a net negative carbon footprint!

How do we do this?

We carefully select the most sustainable shipping and packaging options. 

We also use carbon-negative ingredients (like biochar) and avoid unsustainable ingredients like peat and perlite. 

Moreover, every bag of Rosy potting mix captures 2kg of CO2 from the atmosphere.

How to Grow a Thriving Flower Garden 

Flowers brighten up any space. 

Plant them in an in-ground garden bed, create a beautiful container garden, or keep flowering houseplants in your room for extra color or fragrance.   

The catch?

Flowering plants need the right soil and conditions to, well…flower.  

Let’s explore what goes into the best soil and care for flowers: 

1. Indoor Soil for Flowers

Healthy soil for indoor flowering plants should have:

  • Sufficient plant nutrients: Organic matter, microbes, and nutrients (like phosphorus and nitrogen) supply plant food for plants to grow and produce beautiful flowers.

    You could add fertilizer to enrich plant soil, but synthetic fertilizer can harm the soil pH level and microbes. Bone meal or worm castings are good sources of plant nutrients if you prefer an eco-friendly and organic fertilizer.
  • Good structure: Poor soil may compact over time, limiting airflow around the roots. Use potting soil with soil amendments like biochar, orchid bark, mulch, or earthworm castings, which enhance structure and aeration.
  • Proper drainage: Use well-draining soil to avoid root rot from excessive moisture. However, it shouldn’t drain too quickly, or the plants won’t be able to absorb water.

For a potted plant, use a nutrient-rich growing medium like Rosy’s indoor potting soil — it’s well-formulated for planting flowers. 

2. Outdoor Soil for Flowers

Generally, you may find four types of soil (native soil) in your garden:

  • Silty soil: Silt soil can be relatively good soil for outdoor flower beds. It may have good organic matter and moisture retention but could compact when wet.
  • Clay soil: Clay soil is generally considered poor soil because it’s slow-draining.
  • Sandy soil: Sandy soil tends to have poor moisture and nutrient retention.
  • Loam soil: Loam is a mixture of silty, clay, and sandy soil. It’s usually good soil, though it may contain rocks.

Depending on the soil type, decide whether you need to supplement the native soil with store-bought topsoil.

How does that work?

You can purchase bagged soil (garden soil) at a garden center or online retailer. 

Usually, bagged soils are enriched with compost and can improve the soil in an in-ground flower bed or vegetable garden plot. 

Mix our Rosy soil with the existing soil in your in-ground flower bed or vegetable garden plot. This will improve the soil characteristics to support flowering plant growth.

3. Light, Watering & General Care

Follow our handy tips to give your flowers the best possible care:

  • Research your flowering plants before planting to determine what kind of light they need – bright sunlight, indirect light, partial shade, etc.
  • Water your flowers in the early morning or evening so that the sun doesn’t evaporate the moisture before the plants can absorb it.
  • Water the soil only when the top 1-2 inches are dry to avoid overwatering. 
  • Feel free to pick your flowers as they bloom. Remove the spent flower heads or brown foliage to encourage new growth.

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.
