Slow-release granular NPK 15-6-15 fertiliser for abundant flowering and stronger roses.
Concime Rose Leader is a slow-release mineral granular fertiliser, NPK (Mg-S) 15-6-15. Developed for bush roses, climbing roses, standard roses, and ground-cover roses: progressive nitrogen + potassium + magnesium + sulfur for continuous nutrition throughout the full growing cycle. 1 KG granular format.
Features
The progressive-release nitrogen builds a reserve that the plant uses gradually throughout the growing cycle. This supports repeated flowering without stress from overdosing. Magnesium and sulfur increase photosynthetic efficiency and intensify petal colour. Potassium supports woody tissue and strengthens overall plant resilience.
Apply in late winter and after flowering. For roses in open ground: 40–60 g per m². For ornamental containers: spread the product a few centimetres from the plant and work it lightly into the soil. Adjust the dose according to pot size. Suitable for bush roses, climbing roses, standard roses, and ground-cover roses. 1 KG granular format.
