Hortulani MicroBiological Fertiliser for Roses is a biologically active soil enhancer formulated specifically for roses. It improves soil structure, stimulates root development, and boosts the absorption of essential minerals. The inclusion of nitrogen-fixing bacteria allows plants to access atmospheric nitrogen, reducing reliance on chemical fertilisers. This rose fertiliser supports early and rich flowering, while also helping plants absorb nutrients vital for successful overwintering. Suitable for use in organic gardening under EU Regulation No. 2021/1165.
- Improves soil quality and structure
- Stimulates strong root growth and nutrient uptake
- Promotes early and abundant flowering
- Contains nitrogen-fixing bacteria to reduce synthetic fertiliser use
- Safe for humans, animals, bees, and pollinators
Dosage:
500g per 5 medium-sized rose plants. Increase dosage for larger plants or depleted soils (2–3 times). Overuse does not harm plants, people, animals, or the environment.
Usage Instructions:
For soil improvement, mix into the top 10–15 cm of soil and keep moist. During planting, apply near or in direct contact with roots. For established roses, work into the soil around the root zone. For indoor roses, mix into the substrate or top layer. Reapply several times per season for best results.

Used it for three roses, adding it to the soil and placing a compost mulch on top. Just what I needed

Very quick delivery and so pleased that it was organic, I have planted the new rose tree yesterday so no t able to say how good it is for growth, but I will try to find my review again when the roses are grown and hopefully in bloom so that I can add a photo. Watch this space—
