Vegan Compost

Our plant-based, aged compost is ideal for any indoor plant, including ferns.

Here’s why:

It’s rich in organic matter and provides the optimum soil structure and drainage for growing ferns.

It has essential plant nutrients, like nitrogen and potassium, minimizing the need for synthetic or chemical fertilizers.

It provides the right conditions for beneficial microbes to thrive.

Carbon-Negative Biochar

Biochar is a light porous substance that improves soil drainage and locks in nutrients. 

It keeps your soil fertile for longer periods.

The best part?

Every ton of biochar produced removes three tons of CO2 from the carbon cycle. So it’s Earth Positive — unlike conventional soil additives, like sphagnum peat moss and perlite.  

Root Boosting Mycorrhizae

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

Even better?

The fungi release a gum-like substance (called glomalin) that helps lock in moisture, making it ideal for moisture-loving ferns.

Step 1: Pre-Moisten

Pre-moisten your Rosy fern soil before planting your ferns.

How?

Put the soil mix in a container and sprinkle water until it retains enough to release a few drops when pressed.

Step 2: Pot or repot

Fill up 1/3 of a well-draining pot with the moist soil mixture. 

Step 3: Plant

Gently release your indoor plant from its current soil without disturbing the root ball. 

Then, center the plant into the container with Rosy fern soil mix. Fill the remaining space with pre-moistened soil, leaving an inch at the top for easy watering. 

Step 4: Water

For the first watering, water the fern from the top and let the excess drain out. 

For future watering, we suggest bottom watering (by placing the pot in a tray with water). This allows the soil to absorb water evenly. 

Occasionally, water the soil from the top to flush excess salt deposits.

Rosy’s entire supply chain 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 mix traps more than 2 kg of CO2 from the carbon cycle!  

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

Fern Soil & Care Guide

Ferns are flowerless plants with intricate foliage and a frond leaf (divided leaf) structure. 

Most fern stems (also called rhizomes) grow horizontally, making them perfect indoor plants. 

But some varieties, like tree ferns, have elevated rhizomes and grow vertically.

Popular indoor fern varieties include:

  • Boston fern (aka Sword fern or Nephrolepis exaltata)
  • Maidenhair fern (Adiantum)
  • Japanese holly fern (Cyrtomium falcatum)
  • Staghorn fern (Platycerium) — a popular variety of epiphytic ferns
  • Button fern (Pellaea rotundifolia)
  • Bird’s Nest fern (Asplenium nidus)

Fancy an evergreen fern for your garden?
Suitable outdoor fern varieties include:

  • Autumn fern (Dryopteris erythrosora)
  • Asparagus fern (Asparagus setaceus)
  • Cinnamon fern (Osmunda cinnamomea)
  • Ostrich fern (Matteuccia struthiopteris)
  • Lady fern (Athyrium filix-femina) 

You can even grow some outdoor fern varieties (like ostrich fern) inside, but they need specific conditions to flourish as houseplants.

Here’s what you need to know to grow fern plants:

1. Choose the Right Soil for Ferns

Ferns have a shallow root system and require potting soil mix that’s:

  • Loose to support their fibrous root ball.
  • Moist and well-draining (ferns thrive in damp and humid conditions).
  • Rich in organic matter to provide the nutrients for fern growth.

Looking for the best soil mix for growing ferns?

Instead of regular potting soil, use a soil mix specifically crafted for ferns, like Rosy’s fern mix.

This well-draining soil mix is perfect for all types of ferns — perennial ferns, evergreen ferns, tropical ferns, or even a deciduous fern.

2. Maintain Adequate Moisture Levels

Most ferns need moist soil to thrive.

How do you ensure optimum humidity when growing ferns indoors?

Here are a few pointers to help you grow fern plants:

  • Water your potted fern when the top 2-3 inches of soil is dry to keep the soil moist. Overwatering could cause root rot.
  • Place a humidifier near a potted fern. It’ll help prevent the browning of leaves (common in the southern maidenhair fern).

For dry regions, consider a fern plant that prefers low humidity, such as:

  • Bird's Nest fern
  • Boston fern
  • Holly fern
  • Staghorn fern
  • Rabbit’s Foot fern

3. Provide Indirect Light Exposure

Most indoor and outdoor fern varieties require plenty of indirect sunlight year-round, especially during fall and winter.

Bottom line?
Plant ferns in areas with dappled shade (or partial shade).

Some hardy fern varieties, like northern maidenhair fern, can survive under full sun. 

But direct sunlight can dry the soil and damage fern frond leaves.  

4. Other Fern Care Tips

Some best practices for a healthy fern plant include:

  • Pick indoor and outdoor ferns according to your region. In the US, go for native fern varieties like lady fern or Christmas fern (Polystichum acrostichoides).
  • Prune dead frond leaves periodically to promote new growth.
  • Some ferns, like maidenhair ferns, need alkaline soil. If you have acidic soils, add limestone to increase the pH. 
  • Periodically add mulch to your indoor fern potting soil to increase moisture retention and organic matter.

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.

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.

Repotting my plants

I received my FIRST order on Saturday. The bag was huge! I repotted my neanthe Bella palm and she is adjusting nicely. Then I used the rest to repot a huge sansevieria that I received last month and which was rootbound. This soil was extremely easy to work with and I managed to transfer my sansevieria into a larger pot with no difficulty. I appreciate the time which the team has taken to answer all of my questions regarding this soil. I am highly recommending and will definitely purchase again

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 🤗.

Love this soil!!

I got a bag of Rosy just in time to repot a few plants. Loved it so much that I ordered two more bags. I absolutely loved how well my plant babies adjusted, there was no stress or plant shock. They have been rocking it out in Rosy soil for a good 3-weeks now, still doing great and even have new growth on a few.

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!

Well worth using!

I used Rosy soil to plant succulents. I mixed it with a little bit of succulent mix and within 2 weeks, the succulents had grown larger and had new growth shoots. I bought more to transplant herbs for the spring. It's well worth the price and it's all I'll buy now.
