When to Plant Chrysanthemum Seeds
Core introduction to the text: Learn about the timing for planting chrysanthemum seeds, as well as related experiences in chrysanthemum planting time and methods. Let's take a look together!
Chrysanthemum is a very ornamental plant with various flower shapes. They compete in beauty when in full bloom, which is quite lovely. Chrysanthemums are generally planted in spring when the climate is suitable for their rapid growth. It is usually recommended to use the division method, cutting off the branches that grow in the spring to dry them out before planting them in the flower pot. Let me introduce the planting of chrysanthemums in detail below!
1. When to Plant Chrysanthemum
Planting chrysanthemums usually takes place during Qingming in spring when temperatures begin to rise, which can increase the survival rate. In early spring, chrysanthemums will produce many branches, and it is generally recommended to propagate using the division method. Cut these divisions and place them in a shaded area to dry, then plant them in moist soil. They can root well after about half a month.
2. Soil
Planting chrysanthemums does not require a very large pot; ordinary small clay pots are suitable. The soil can be a mixture of humus soil and sandy loam soil, which is rich in nutrients and has good water permeability and breathability. Additionally, some cake fertilizer can be added, with the ratio of humus soil, sandy loam soil, and cake fertilizer controlled at 6:3:1.
3. Watering and Fertilizing
Planted chrysanthemums need plenty of fertilizer to make the flowers more beautiful. During spring and summer, a small amount of nitrogen fertilizer can be applied every ten days. In autumn, which is the flowering season, liquid fertilizer should be used once a week after the flower buds appear. No more fertilizer is needed once the flower buds have formed.
As for watering, it is usually done when the soil is almost dry, making sure to water thoroughly. Of course, there should be no waterlogging in the soil, as this can cause the roots of the chrysanthemum to rot.
4. Pinching
When the chrysanthemum grows to about 10 centimeters, pinching can be done, leaving only 4 to 5 leaves at the base. After new leaves grow, the center can be pinched again. This allows the plant to branch out and helps control its height. After pinching, the plant should be pruned, removing weak and withered branches, retaining 3 to 5 branches.
5. Thinning Buds
In September, chrysanthemums will form buds. Only the top buds should be left, removing the lower ones.
6. Propagation Methods
1. Cutting. Select plump buds, remove the lower leaves, and plant them in the soil, maintaining a temperature of about 7 to 8 degrees Celsius.
2. Division. The timing is generally around Qingming. The chrysanthemum divisions are transplanted to another potting soil.
3. Seeds. Seeds will germinate when the temperature is above 10 degrees Celsius. They can be scattered from February to April, and under normal conditions, the seeds will bloom.
4. Ground Insertion. Mainly use garden soil mixed with one-third rice husk ash. If placed outdoors, shading is necessary.
5. Grafting. Use yellow wormwood or green wormwood as the rootstock for grafting, which can be done in late April when the seedlings have grown tall.
7. Disease and Pest Control
Chrysanthemums may encounter diseases such as spot blight, wilt, and various pests during growth. Spot blight is more likely to occur in mid-to-late April and can be controlled by spraying a 1:1:100 Bordeaux mixture and 50% thiophanate-methyl 1000倍 liquid. Wilt can be severe from early June to July and can be treated by sprinkling lime powder or 50% carbendazim 1000倍 liquid in the potting soil. Pests can appear throughout the year and can be prevented by spraying pesticides appropriately.
