Bio Alg – natural nourishment for healthy and strong roses
Give your Belle Epoque roses and other garden plants a powerful boost with Bio Alg, a 100% organic fertilizer based on seaweed extract. This natural nourishment stimulates root growth, improves soil structure, and increases the resistance of roses against diseases, pests, and stress factors such as drought or shade.
Why choose Bio Alg?
- Stronger soil and roots – promotes the uptake of nutrients and water, ideal for climbing roses and bush roses.
- Natural growth stimulant – supports rich blooming and deeper colors in yellow, red, purple, and orange roses.
- Organic and sustainable – certified product, free from synthetic additives.
- Stress reduction – helps plants recover after temperature fluctuations or nutrient shortages.
Use in the rose garden
Bio Alg is suitable for all kinds of roses, from classic English roses such as the David Austin roses to special varieties like Ingrid Bergman or Golden Celebration. Use the product as:
- Basic fertilization when planting roses.
- Support in borders or cutting gardens for healthy, long-lasting bloom.
- Extra care for climbing roses by fences or pergolas.
Usage tips
- During the growing season (spring-summer): give 1–2 ml per liter of water, 1 to 3 times per week.
- During the blooming phase: gradually increase to 4 ml per liter of water for full and strong flowers.
- Leaf application: can also be used as a leaf spray for quick absorption.
With Bio Alg you restore the natural balance in your garden. Order easily online through our nursery in Aalsmeer and experience the difference: healthy, strong roses that bloom beautifully season after season.
Forty years of nothing but roses
Belle Époque is a family business, not a wholesaler. From our greenhouses in Aalsmeer, we have been growing only roses for over four decades — and we personally select every plant we send out. This way, you receive at home not a catalog rose, but a plant ready to grow.
"Beautiful climbing rose, bloomed abundantly in the very first year! Well packaged and exactly what I expected based on the description. Belle Époque truly delivers top quality."
"The rose is well packaged and looks beautiful. Fast delivery, and the personal advice via email was very valuable — I wasn’t sure where to plant it."
"Amazing quality & service. I ordered two New Dawns and they are developing beautifully in the garden. Fast shipping from Aalsmeer to Belgium — would absolutely order again."
