Overview

In ornamental plant cultivation, plant quality directly determines market value. Roses and cut flowers are harvested intensively over long periods—which places a correspondingly high strain on the plant. The comprehensive approach combining AgroArgentum® and AgroCyprum® keeps the plant’s metabolism active throughout the entire growing season.

Application

For roses, AgroArgentum® Forte or O-Mix is used at a higher dosage—specifically without boron. AgroCyprum® has proven effective year-round for roses and other ornamental plants and can be integrated into existing spray schedules.

Results

Increased production: more harvested stalks per unit area
Longer stem length
Weight Gain
Larger and more uniform flower heads
More resilient and robust plants

With over 28 years of experience growing roses, I've never seen anything like it.

Conclusion

With roses in particular, this holistic approach pays off: The plant remains productive through many harvests, rather than losing vigor over the course of the season.
