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.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
