Blueing Hydrangea Soluble Fertilizer with Aluminum Sulphate - Masso

The Hydrangea Blueing Soluble Fertilizer with aluminum sulphate is a complete and balanced formula of nutrients, with rapid and prolonged action. Its high content of aluminum sulphate allows blue hydrangea flowers to maintain their beautiful colour and quickly return to blue for those that have turned pink due to insufficiently acidic soil. It is used by watering at the base of the bushes. Easy to measure with the 10g measuring spoon. An 800-gram box can prepare up to 800 litres of solution.

This product comes in the form of a powder to be dissolved in watering water, in pots or in open ground. The concentration and specific composition of this fertilizer are ideal for hydrangeas. Its high content of Potassium and Magnesium ensures abundant and prolonged flowering and good assimilation of all nutrients. Aluminum sulphate, on the other hand, is known for its blueing properties on hydrangeas. The action of this fertilizer is both rapid and prolonged. Its formulation is N.P.K. 15-5-15 + 2% MgO + 5% aluminum sulphate.

This means that it is composed of:

• 15% Nitrogen (N): this element contributes to the development of non-reproductive aerial parts of the plant, especially leaves and stems.
• 5% Phosphorus (P), which strengthens plant resistance and contributes to root development.
• 15% Potassium (K): essential for good harvests, it promotes flowering and fruit development.
• 2% Magnesia or magnesium oxide (MgO): this trace element promotes the assimilation of nitrogen, phosphorus, and sulphur. It also intensifies the colour of flowers and foliage, as well as the taste quality of fruits and vegetables.
• 5% Aluminum sulphate (Al₂(SO₄)₃): when introduced into the soil, this compound releases sulfuric acid. It temporarily acidifies excessively alkaline soil. Caution, aluminum is toxic to certain acidophilous plants!

For optimal results: apply the Blueing fertilizer from late winter to summer.

Instructions:
Use the exact dose of Masso Garden Hydrangea Blueing, using the measuring spoon included in the box. One level measuring spoon represents 10 grams. Dissolve the powder in warm water (10g in 10 litres of water) and pour the solution around the base of the plant without wetting the leaves. We recommend watering with the fertilizer solution only on pre-moistened soil.
