Essential Nutrition for a Stunning Flower Garden Full of Roses and Blooms

For abundant flowering and long-lasting colour, roses and flowering plants require balanced nutrition. Only with the right ratio of essential nutrients—such as nitrogen for leaf growth, phosphate for root development and flower formation, and potassium for strong cell walls and resilience—can ornamental plants truly thrive. These elements are vital for sturdy stems, full flower buds, and vibrant blooms that shine throughout the season.

This complete fertiliser is specially developed to meet the specific nutritional needs of flowering ornamentals such as roses, perennials, and profusely flowering annuals. The balanced formula supports strong, even growth and stimulates abundant flowering, full of fragrance and colour. Plants are strengthened from within, develop a deeper root system, and become more resistant to stress factors such as drought or disease.

The result? Healthy, vigorous plants with more flowers, larger flower heads, and more intense colours. Deep shades of red, pink, yellow, and purple burst through the greenery and fill the garden with a spectacular floral display. The delightful scent of blooming roses and other flowers spreads to every corner of the garden. This creates a flowering haven that impresses for months with lush blooms, striking colours, and fragrance that lingers throughout the space.

Magnesium for Strong Leaves and Vivid Blooms

Magnesium is essential for the formation of healthy, deep-green leaves and efficient photosynthesis. A deficiency can quickly lead to leaf discolouration, reduced leaf quality, and weakened flower development. Roses and other flowering plants are particularly sensitive to this and benefit greatly from targeted supplementation.

This fertiliser is rich in readily absorbable magnesium and provides roses and flowers with exactly what they need for vigorous growth and lavish flowering. Magnesium also improves the uptake of other nutrients and enhances the intensity of flower colours, resulting in visibly healthier and more radiant plants.

Composition

Organo-mineral NPK+MgO fertiliser 9+4+8(+2) (This fertiliser is formulated in accordance with Regulation (EC) No. 1069/2009)

  • 9.0% Total nitrogen (N)

  • 2.2% Organically bound nitrogen (N)

  • 5.4% Available nitrogen (N, CaCl₂-soluble)

  • 1.4% Urea nitrogen (N)

  • 4.0% Total phosphate (P₂O₅)

  • 2.4% Neutral ammonium citrate-soluble phosphate (P₂O₅)

  • 8.0% Total potassium oxide (K₂O)

  • 2.0% Total magnesium oxide (MgO)

  • 9.0% Water-soluble sulphur (S)

  • 0.2% Water-soluble sodium (Na)

  • 52.6% Organic matter

Organic Enrichment for Soil and Bloom Performance

This fertiliser contains 52.6% organic matter and is rich in minerals and trace elements, promoting active soil life and improved soil structure. The organic content stimulates microbial activity in the soil, enabling nutrients to be released and absorbed more efficiently by the roots of roses and flowering plants.

A humus-rich soil retains water better, improves aeration, and provides a stable foundation for healthy growth. Together with the minerals and trace elements, the soil is naturally enriched, preventing nutrient deficiencies in plants. The result: stronger plants with robust root development, longer flowering periods, and more vibrant bloom colours.

Gentle Action for Sensitive Roots

Roses and flowering ornamental plants have finely branched root systems and are sensitive to unbalanced nutrition or saline fertilisers. An incorrect composition can cause root stress, growth disorders, and reduced flowering.

This fertiliser is gentle on sensitive plants and respects the natural balance of the soil. The combination of organically bound nutrients, slow-release nitrogen, and mild minerals promotes a healthy root environment. This encourages strong root growth, vigorous foliage, and a rich, long-lasting flowering display with deep, vibrant colours. Thanks to its balanced formulation, this fertiliser is also suitable for professional use, such as in cultivation.

Specially developed for roses, flower borders, and other blooming ornamental plants.

Efficiently Spreadable for Even Growth Results

The fertiliser is pressed into firm, uniform pellets that do not crumble and produce virtually no dust. Thanks to this high-quality granule structure, the product is easy to distribute evenly, whether by hand or with a spreader. This prevents localised overdosing and ensures balanced nutrient distribution across the entire area, even in hard-to-reach places such as pots, borders, planting holes, and between perennials.

Due to the consistent shape and ideal weight of the granules, broad and precise spreading is possible—both in ornamental gardens and for professional use in cultivation beds and growing plots.

Instructions for Use

Evenly spread the fertiliser around the plants and lightly work it into the top layer of soil to encourage uniform nutrient distribution and improve uptake by the roots. After fertilising, water generously to accelerate the effect, and ensure sufficient moisture in the following days for optimal nutrient absorption. Clay minerals in the composition enhance the soil's moisture and nutrient-holding capacity. Fertilise preferably in the morning or evening, when the sun is less intense, and ideally just before a rain shower.

During the first growing season, most of the nitrogen is released. The remaining portion becomes gradually available in the following years through microbial conversion. Phosphate and potassium are fully utilised by the plants.

Dosage

  • New plantings: Mix 50–100 grams of rose fertiliser into the planting soil, depending on the plant's size, and add sufficient planting compost. Water the roses generously after planting.

  • Established plants: Apply 50 grams per square metre to roses in early spring after pruning, at the start of new growth. Repeat this in spring and approximately three weeks after flowering begins, depending on the variety—usually in summer. Larger flowering shrubs may require a slightly higher dose, while perennials may need a little less. From autumn onwards, roses no longer require fertilisation.

Storage

This fertiliser will retain its quality for up to 2 years if stored in a cool, dry place away from direct sunlight.
