When is it suitable to plant chrysanthemums
Main text core guide: Understanding the best time for planting chrysanthemums and some small knowledge of growing flowers, the following is a detailed answer from the editor.
Chrysanthemums are very ornamental plants with diverse flower shapes. When they bloom, they compete for beauty and are very beautiful. Chrysanthemums are generally planted in spring, when the climate is suitable for their rapid growth. It is usually recommended to use the division method, where branches that sprout in spring are cut and dried before planting in flower pots. Let's introduce the planting of chrysanthemums in detail below!
1. When to plant chrysanthemums
Planting chrysanthemums usually takes place during Qingming in spring, when temperatures begin to rise, which can increase survival rates. In the beginning of spring, chrysanthemums grow many branches, and it is generally recommended to propagate using the division method. Cut these divisions, place them in a shaded area to dry, and then plant them in moist soil. In about half a month, they can root well.
2. Soil
Planting chrysanthemums does not require a very large pot, and ordinary small clay pots are suitable. The soil can be a mixture of humus and sandy loam, which is not only rich in nutrients but also has good water permeability and breathability. Additionally, some cake fertilizer can be added, with the ratio of humus, sandy loam, and cake fertilizer controlled at 6:3:1.
3. Watering and Fertilizing
Planting chrysanthemums requires 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, when it is their flowering season, a liquid fertilizer should be used once a week after the flower buds appear. Once the flower buds form, there is no need to continue fertilizing.
In terms of watering, it is generally done when the soil is almost dry. Of course, there should be no accumulated water in the soil, as it can cause the roots of chrysanthemums to rot.
4. Pinching
When chrysanthemums grow 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. The reason for this is to encourage branching and help control the plant's height. After pinching, the plant should be pruned, removing weak and dead branches and retaining 3 to 5 branches.
5. Thinning flower buds
In September, chrysanthemums will form flower buds, and the lower ones should be removed, leaving only the top ones.
6. Propagation methods
1. Cutting. First, select full and plump buds, remove the lower leaves, and plant them in the soil, maintaining a temperature of around 7 to 8 degrees Celsius.
2. Division. The timing is generally around Qingming, where chrysanthemum divisions are transplanted to another pot of soil.
3. Seeds. When the temperature is above 10 degrees Celsius, the seeds will germinate. From February to April, the seeds can be broadcast, and under normal conditions, they will bloom.
4. Ground insertion. Use garden soil mixed with one-third of rice husk ash. If placed outdoors, shading is necessary.
5. Grafting. Use yellow wormwood or green wormwood as rootstocks for grafting, and by the end of April, when the seedlings have grown tall, grafting can be performed.
7. Disease and pest control
During the growth of chrysanthemums, they may encounter various diseases such as leaf spot, wilt, and various pests. Leaf spot is more likely to occur in mid-to-late April, and a 1:1:100 solution of Bordeaux mixture and 50% thiophanate-methyl 1000倍 liquid can be sprayed. Wilt is more severe from early June to July, and lime powder or 50% carbendazim 1000倍 liquid can be sprinkled in the potting soil. Pests appear throughout the year and can be prevented by appropriately spraying pesticides.
