Complete blue fertilizer NPK 12,12,17 + 2 MgO
The bag of fertiliser arrived with granules compacted into several large lumps, a bag that was likely very old as the granules had lost their colour. I would not recommend it.

This blue UAB NPK 12-12-17 (+ 2MgO) complete fertilizer is a universal and versatile fertilizer, with high nutritional power, suitable for all vegetable, fruit, shrub or ornamental crops. Ready to use, it comes in the form of blue granules, a colour that allows for perfect visualization of spreading. The action of this mineral-based fertilizer is fast (a 'boost' effect), but also long-lasting.
The blue UAB universal fertilizer does not come from organic matter derived from living organisms, but from inert mineral matter. Its formulation is as follows: NPK 12-12-17 SK + 2 Mgo. This means that it is composed of:
- 12% nitrogen (N): this element contributes to the development of non-reproductive aerial parts of the plant, especially leaves and stems.
- 12% phosphorus (P), which strengthens plant resistance and contributes to root development.
- 17% potassium (K): essential for good harvests, it promotes flowering and fruit development.
- Potassium sulphate (SK): essential for facilitating nutrient assimilation by plants.
- 2% magnesium or magnesium oxide (2MgO), which promotes the assimilation of nitrogen, phosphorus, and sulphur. This element also intensifies the colour of flowers and foliage.
- 22% water-soluble sulfuric anhydride (SO3).
- Various trace elements including Boron, Copper, Iron, Manganese, and Zinc, which play a similar role for plants as vitamins do for animals.
Uses:
Vegetable gardens, lawns, ornamental gardens, trees, and shrubs.
Dosage: from March to September: 40 to 150g/m² depending on the crops.
To live and multiply, plants need water, about twenty essential nutrients that they find in mineral form in the soil, carbon dioxide (CO2) present in the air, and solar energy essential for photosynthesis. The basic elements, called macronutrients, are nitrogen (N), phosphorus (P), and potassium (K). They must be present in the soil in significant quantities. The secondary elements, less predominant but nevertheless essential, are calcium (Ca), sulphur (S), and magnesium (Mg). Finally, trace elements, necessary in very small quantities, are represented by iron (Fe), manganese (Mn), molybdenum (Mo), copper (Cu), boron (B), zinc (Zn), chlorine (Cl), sodium (Na), cobalt (Co), vanadium (V), and silicon (Si). The role of a fertilizer is to compensate for soil deficiencies and to provide, through optimal dosage, the elements that promote plant growth, flowering and fruit production, or the development of roots, bulbs, and tubers.

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.
