How to grow a single-stem chrysanthemum well
As a premium potted plant in the chrysanthemum family, the single-stem chrysanthemum is deeply loved by gardening enthusiasts for its unique single-flower shape. To cultivate a chrysanthemum with sturdy stems and full blooms, it is necessary to master key techniques such as temperature control and light adjustment. This article systematically sorts out the complete knowledge system from daily maintenance to pest and disease control, helping you create a stunning desktop landscape.
Ⅰ. Management of Single-Stem Chrysanthemum Growing Environment
1.1 Precise Temperature and Humidity Control
The optimal growth temperature should be maintained between 15-28°C. When the temperature exceeds 32°C in summer, ventilation should be strengthened to cool down, and when it drops below 5°C in winter, it needs to be moved indoors. Use a thermometer and hygrometer to monitor in real-time, and配合 morning and evening misting to maintain 50%-70% air humidity.
1.2 Scientific Lighting Plan
Ensure 6 hours of scattered light every day, use a rotating tray to turn the pot 90 degrees every 3 days to ensure even light exposure. Use a sunshade net to filter strong light from 11:00 to 15:00 in summer, and LED grow lights can extend the lighting time to 10 hours/day in autumn and winter.
Ⅱ. Single-Stem Chrysanthemum Shaping Techniques
2.1 Step-by-Step Pruning Method

Implement three-level pinching during the seedling stage: the first pinch is at a plant height of 15cm, leaving 3 true leaves, the second pinch is at the side branches 10cm away, and the last pinch is chosen at the strongest branch for shaping. Use aluminum wire traction to create a 30-45° elegant stem angle.
2.2 Intelligent Water and Fertilizer Management
Use the 'wet-dry' method during the growing period, water thoroughly when the topsoil 2cm is dry. Supplement phosphorus and potassium liquid fertilizer (N-P-K=5-15-45) every week during the bud differentiation period, and use 0.2% ferrous sulfate foliar fertilizer to prevent yellowing.
Ⅲ. Comprehensive Pest and Disease Control
3.1 Disease Warning System
Apply mancozeb before the plum rain season to prevent leaf spot disease, and immediately treat brown spots with benomyl. Regularly replace the topsoil and keep the bottom of the pot well-ventilated.
