☑ An all-natural and earth-positive mix — without any harmful ingredients like peat moss and coco coir
☑ Enhances water retention, improves aeration, and boosts nutrient uptake
☑ Adds abundant organic material to create the best soil for hydrangea

Vegan Compost

Our aged, vegan compost adds high-quality organic matter to the soil mix, improving soil structure and optimizing drainage. 

And since it’s a natural source of nutrients for your hydrangeas, it reduces the need for synthetic fertilizers that harm soil microbes and decrease fertility.

Carbon-Negative Biochar

Our earth-positive biochar, made solely from organic waste material, boosts nutrient and water retention in the soil. This creates the fertile and moist soil that hydrangea plants need. 

Moreover, every ton of biochar produced removes three tons of CO2 from the carbon cycle — preventing it from contributing to climate change.

So, it’s an eco-friendly soil amendment, unlike the peat moss, perlite, and vermiculite in conventional hydrangea mixes. 

Root-Boosting Mycorrhizae

Mycorrhizae (mahy-kuh-rahy-zee) are plant-friendly fungi that improve hydrangea’s water and nutrient uptake by expanding the roots’ reach. This happens with the help of fungal hyphae (branches or filaments) that connect the roots to a larger volume of soil.

The fungi also improve your hydrangea’s resistance to drought, high temperatures, and pests like nematodes and insects. 

Step 1: Pre-Moisten

Before you plant hydrangeas, pre-moisten Rosy to help your hydrangea set in well. 

To do this, add Rosy Hydrangea Soil to a container and water it until the soil holds enough to release a few drops when pressed. 

Step 2: Pot or repot

Take a well-draining container and fill up 1/3 with the pre-moistened hydrangea soil. 

Step 3: Plant

Gently loosen the root ball before planting hydrangea into the container with pre-moistened Rosy. Fill the remaining space with more potting soil, leaving a bit of room for watering.

Step 4: Water

For the first watering, thoroughly water the hydrangea soil mix from the top and let the excess water drain from the pot. 

For future waterings, we recommend bottom watering (by placing your potted hydrangea in a container with water) since it can help avoid overwatering. This, in turn, can reduce fungal infections and leaf spots as your hydrangeas grow. 

At Rosy, we ensure our processes are eco-friendly, from production to delivery. 

Our entire supply chain has a net negative carbon footprint!

How? 

We consciously curate the most earth-positive ingredients (especially biochar), packaging materials, and shipping services. Moreover, each bag of Rosy Hydrangea Soil Mix captures more than 2 kg of CO2 from the carbon cycle.

Hydrangea Soil & Care Guide

Hydrangea, a perennial plant, comes in a wide range of varieties like:

  • Bigleaf hydrangea, French hydrangea, or Mophead hydrangea (Hydrangea macrophylla)
  • Oakleaf hydrangea (Hydrangea quercifolia
  • Peegee hydrangea (Hydrangea paniculata
  • Annabelle or smooth hydrangea (Hydrangea arborescens
  • Mountain hydrangea (Hydrangea serrata
  • Climbing hydrangea (Hydrangea petiolaris

Fun fact: Bigleaf and smooth hydrangea usually have sterile flowers. But lacecap hydrangeas, a cultivar of H. macrophylla, can have fertile and sterile flowers. And unlike fertile flowers, sterile flowers won’t attract bees!

You also have patented types of hydrangea, including Endless Summer hydrangea (Hydrangea macrophylla) and Limelight hydrangea (Hydrangea paniculata). 

But what soil should you use for these hydrangea varieties?

Let’s explore the best soil and other essentials about planting hydrangeas:

1. The Perfect Hydrangea Soil

For growing hydrangeas, you need moist, well draining soil.

Here’s what makes the best soil for your hydrangea plant:

  • Hydrangeas prefer soil with organic matter (like Rosy), which improves water retention and adds nutrients (like nitrogen and potassium) crucial for the new growth of flower buds.
  • Potted hydrangea can thrive in acidic soil and alkaline soil. Interestingly, in some varieties like Hydrangea macrophylla and Hydrangea serrata, the hydrangea color may change with the soil pH!
  • Hydrangea potting soil should be porous for easy drainage and good aeration

That’s why Rosy’s Hydrangea Soil is better than sandy soil or heavy clay soil, which may cause dry roots and root rot.

2. Best Practices for Hydrangea Care

Here are essential tips for growing hydrangeas:

  • Plant hydrangeas either in autumn or early spring.
  • Before planting hydrangeas, ensure the pot is 2-3 times wider than the root ball. 
  • Keep your hydrangea plants in partial shade or a mix of morning sun and afternoon shade. Most hydrangeas, except H. paniculata, won’t thrive in full sun.
  • Water hydrangea whenever the top inches of soil start to dry since the plant prefers moist soil.
  • Fertilize your hydrangea plant with feed or mulch during the growing season.
  • Ideally, prune hydrangea in winter to remove old wood and encourage an early summer bloom of flower clusters.

3. Proven Tips to Change Hydrangea Color (Flower Color)

Species like Bigleaf hydrangea (French hydrangea) change flower color based on the soil pH. 

So here’s how to get a specific hydrangea flower color:

  • Blue hydrangea: soil pH below 5.5 (acidic soil) and availability of aluminum.
  • Purple bloom: pH level between 5.5 to 6.5 (acidic to neutral).
  • Pink blooms: soil pH above 6.5 (alkaline soil). 

Generally, patented flower varieties of hydrangea, like Endless Summer, have their own bloom color kits. But you can also add aluminum sulfate or garden lime to modify soil pH. 

Moreover, it’s easier to change blue flowers to pink blooms than to change pink flowers to blue blooms since alkaline soil makes aluminum unavailable for plants.

Note: Hydrangea flower or bloom color change can take months. And a hydrangea bloom with green or white flowers won’t change its flower color, regardless of the soil pH.

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.
