As one of the most popular flowers in autumn, chrysanthemum cultivation techniques have received much attention. Among these, cuttings are an important method for chrysanthemum propagation, and mastering the right time for cuttings is a crucial step to ensure their survival.
Basic Knowledge of Chrysanthemum Cuttings
Propagation by cuttings refers to inserting a part of a plant (such as a stem, leaf, rhizome, etc.) into soil or other growing medium to reproduce using the regenerative ability of its meristematic tissue. For chrysanthemums, common cutting methods include stem cuttings and scion cuttings.
Best Time for Chrysanthemum Cuttings
After selecting a cutting method, determining the right time is key to ensuring a high survival rate. Generally, the best time for chrysanthemum cuttings is in spring or autumn. For northern regions, spring cuttings are suitable from March to May, while autumn cuttings are best from September to November.
Advantages of Spring Cuttings
Spring cuttings refer to taking cuttings before the chrysanthemum's budding to growing period. As the temperature gradually rises and soil moisture increases, it is conducive to the growth and development of chrysanthemums, resulting in a relatively high survival rate.
Advantages of Autumn Cuttings
Compared to spring, the advantage of autumn cuttings is that the weather gradually cools down, which is beneficial for the root growth of chrysanthemums. At the same time, the sunlight in autumn is gentler, avoiding the damage caused by high summer temperatures. Autumn cuttings are also a good choice.
Pay Attention to the Selection of Cutting Time
Chrysanthemums in different regions and varieties have different growth characteristics, so it is necessary to comprehensively consider factors such as climate, soil, and light when selecting the cutting time. Generally, it is more suitable to perform autumn cuttings before the season of leaf fall and when the temperature gradually cools down.
Prepare the Cutting Materials
Before taking cuttings, it is necessary to prepare the cutting materials. For chrysanthemums, the stems suitable for cuttings should be healthy, flexible, and free from pests and diseases.
Processing Before Taking Cuttings
Before taking cuttings, the cutting materials need to be processed. This mainly includes steps such as pruning, removing leaves, and soaking. These treatments help to improve the survival rate of chrysanthemums and also help to control pests and diseases.
Pay Attention to the Depth of the Cuttings
When taking cuttings, it is necessary to pay attention to the depth. Generally, the cutting part should be buried in the soil about 3-5 cm to ensure full contact between the cutting material and the soil.
Reasonably Control the Amount of Irrigation
For a period after taking cuttings, it is necessary to control the amount of irrigation reasonably. Too little irrigation will cause the cutting material to die from water loss, while too much irrigation will lead to problems such as root rot.
Focus on Fertilization
Chrysanthemums after cuttings need appropriate fertilization to provide nutritional support for their growth and development. Generally, the fertilization interval is about 10-15 days, and it is also necessary to pay attention to the control of fertilization concentration.
Regular Pruning
During the growth process of chrysanthemums, regular pruning is necessary to maintain their good growth condition. This also helps to promote branching and growth, and improve their quality.
Pay Attention to the Prevention and Control of Pests and Diseases
During the growth process of chrysanthemums, it is necessary to pay attention to the prevention and control of pests and diseases. For example, diseases such as anthracnose and downy mildew, and pests such as aphids and whiteflies can cause harm to chrysanthemums.
Regularly Change the Pot
During the growth process, chrysanthemums need to have their potting soil changed in a timely manner. This helps to maintain the soil's aeration and fertility, and improve their growth quality.
Pay Attention to Temperature Regulation
After taking cuttings, it is necessary to pay attention to the issue of temperature regulation. In low-temperature or high-weather conditions, it is necessary to take measures to maintain a suitable temperature to ensure the success rate of the cuttings.
Conclusion
For friends who love chrysanthemums, mastering the right time for cuttings is the key to ensuring their survival rate. After selecting the cutting time, it is also necessary to pay attention to the selection and treatment of materials, irrigation, fertilization, and other issues. Only by comprehensively considering these factors can chrysanthemums survive easily and bring us a wonderful visual enjoyment.
