Growing Tips
Cut stems when the bud is at the 'pencil point' or 'showing color' stage for optimal vase life; harvest in the cool early morning.
Greenhouse production allows year-round supply; maintain day temperatures of 21-27C and night temperatures of 15-18C for best bloom quality.
Integrated pest management is critical — roses attract many pests; biological controls (predatory mites for spider mites) reduce chemical inputs.
