CROP CULTIVATION TIPS

Chrysanthemum

Chrysanthemums remain one of the most widely produced potted and cut flower crops worldwide, driven by steady demand for uniform quality, reliable schedules, and strong color. As greenhouse production continues to advance, more growers are turning to controlled environments to deliver consistent, high‑quality mums throughout the year.

But producing chrysanthemums successfully requires precise climate management, especially since they are a short day crop with strong responses to temperature, humidity, and light. From maintaining stable day and night temperatures to managing high light levels and ensuring dependable blackout, mums perform best when every climate factor works together.

At Svensson, we support chrysanthemum growers around the world in creating these optimal conditions. Through light control, climate balance, and energy saving strategies, our solutions help you produce uniform, high‑quality mums in any season or location.

  • Humidity:
    Steady humidity helps reduce disease pressure and keeps mums resilient after watering.
  • Temperature:
    Mums thrive with stable conditions around 17°C at night and 20–23°C during the day.
  • Light:
    As a short‑day crop, mums need dependable blackout and shading when light exceeds about 800 W/m².
