Flower Hydrangea Bluing Fertilizer 600g – Intense Blue & pH Corrector

Flower Hydrangea Bluing Fertilizer 600g is the ultimate tool for any gardener who refuses to settle for washed-out colors, designed specifically to turn pink or pale hydrangeas into a visual spectacle of intense blue. If you are looking to manipulate the color of your flowers with the same precision you use to control your crop's parameters, this acidifying agent is the key to unlocking those vibrant tones hidden in your plant's genetics.

Why have your hydrangeas lost their blue color?

Are you frustrated seeing your precious blue hydrangea turn a dull pink or whitish color after just one season? It is one of the most common disappointments for growers: you buy a spectacular plant, transplant it, and it loses its essence. You feel like you've done something wrong, but the problem isn't the plant, it's the chemistry of the ground.

The agitation of seeing your garden lose its vibrancy is real. Without the right acidity (pH) and specific minerals, the plant simply cannot produce blue pigment. It's like trying to grow a high-performance strain without the right nutrients; the result will always be mediocre. If you don't correct the soil, that blue will never come back, no matter how much water or generic food you give it.

The solution is chemistry, and it's in this box. The Flower Bluing Fertilizer acts directly on the root cause. By supplying aluminum sulfate, it lowers the pH of the substrate (acidifies it) and provides the aluminum that the hydrangea needs to synthesize the blue color. It is the direct fix to restore the personality of your garden.

Technical characteristics of the Bluing Agent

• Brand: Flower.

Advantages of using Flower Bluing Fertilizer vs. Generic Fertilizers

You might think that any fertilizer for flowering will do the trick, but that's a mistake when it comes to hydrangeas. Generic boosters feed the plant, but they don't change the chemical conditions required for the blue color.

• Specific pH Control: Unlike a standard NPK, this product lowers the pH to a range of 5.0-5.5, essential for the plant to absorb aluminum.
• Prevents Chlorosis: Thanks to the extra contribution of Iron and Magnesium, it prevents the leaves from turning yellow, keeping the foliage deep green.
• Fast Assimilation: Being soluble, the roots absorb the aluminum quickly, accelerating the color change process before the flowering peak.
• Versatility: You can use it on potted plants or directly in your garden soil.

Real benefits for your garden

By using this bluing agent, you are not only changing a color; you are optimizing the health of your acidophilic plants. You will notice that the flowers develop a deep, electric blue, standing out from the rest of the garden. It is the difference between a standard plant and a professional-looking specimen.

In addition, by correcting the pH, you improve the absorption of other nutrients. Your hydrangeas will look more vigorous, with stronger stems capable of supporting the weight of the buds. It is the satisfaction of having total control over the aesthetics and biology of your crop.

How to use Flower Hydrangea Bluing Fertilizer

1. Timing: Start applying in late winter or early spring, before flower buds form.
2. Dosage (Watering): Dissolve 10g (approx. one tablespoon) in 5 liters of water.
3. Dosage (Soil): Spread about 10g around the base of the plant and mix lightly with the substrate.
4. Frequency: Apply once a week until the desired color is achieved.
5. Maintenance: Once blue, apply once a month to maintain acidity.
6. Tip: Ensure the soil remains moist but not waterlogged to facilitate aluminum uptake.

Frequently Asked Questions

Can I use it on white hydrangeas?

No, white hydrangeas do not have the pigment necessary to turn blue. This product works on pink, red, or purple varieties.

Is it compatible with other fertilizers?

Yes, you can combine it with other fertilizers, but try not to mix them in the same irrigation water to strictly control the EC and pH.

How long does it take to see results?

It is a gradual process. You should start applying it before flowering begins. If the flowers are already formed, the change will be more visible in the next season.

Does it work in pots?

Absolutely. In fact, it is easier to control the pH in a pot than in open ground.

Personal Experience of Pevgrow’s CEO (Alan)

"Although my specialty is usually other types of flowers, I have a weakness for a well-kept garden. I've used the Flower Bluing Agent on the hydrangeas I have at home and the change is radical. The key I've found is consistency: don't wait for the flower to open. I start applying it when the plant wakes up from winter. Not only do you get that electric blue that looks like Photoshop, but the leaves stop looking yellowish thanks to the iron. If you like to have control over your plants, you will love seeing how they react to the pH change."
