How to propagate chrysanthemums through cutting
As a traditional famous flower, mastering the correct cutting technique is key to cultivating healthy plants. This article will systematically explain the full process of chrysanthemum cutting from substrate preparation to post-cutting care, and reveal the golden period for the best cutting time, helping gardening enthusiasts achieve efficient propagation.
Key points of core chrysanthemum cutting technology
Substrate mixing process
High-quality substrates need to balance breathability and water retention: it is recommended to mix garden soil, river sand, and decomposed leaf soil in a ratio of 5:3:2, and add 200g of bone meal per cubic meter to enhance fertility. The mixture should be sifted and disinfected before use to ensure no pathogen residues.
Cutting treatment tips
Select semi-woody branches from the current year, retain 3-4 buds, and keep 2 compound leaves at the top. Use a 45-degree oblique cut method for the cut, and dipping in IBA rooting powder (concentration 500ppm) can enhance the formation speed of callus tissue.
Scientific cutting operation
Use the deep hole shallow insertion method: first make a hole in the substrate with a stick (depth is 1/3 of the cutting), then insert and press the surrounding soil. Maintain a spacing of 8-10cm between plants and 15cm between rows to ensure good ventilation and light.
Intelligent care management
Build a mini greenhouse to maintain 85% humidity, and ventilate for 1 hour daily from 10:00 to 15:00. Use an intermittent misting system to keep the substrate moist but not waterlogged. After 3 weeks, gradually increase the light intensity to promote the lignification of the roots.
Analysis of the golden period for chrysanthemum cutting
When the average daily temperature is between 18-25°C in April and May, the activity of endogenous auxins in the plant reaches its peak, and the survival rate of cuttings can reach over 95%. For additional cuttings in autumn, from late September to early October, it is necessary to use ground heating cables to maintain a ground temperature of 20°C ± 2°C.
By precisely controlling the three elements of temperature, humidity, and light, combined with standardized cutting operations, it is possible to achieve multi-batch propagation throughout the year. It is recommended for beginners to start with spring cuttings and then try operations in other seasons after mastering the technical essentials.
