Chrysanthemum is a very ornamental plant with various flower shapes. They compete in beauty when blooming, which is very beautiful. Chrysanthemums are usually planted in spring when the climate is suitable, which is conducive to their rapid growth. It is generally recommended to use the division method, cutting off the branches that sprout in spring to dry them before planting them in pots. Let me introduce the planting of chrysanthemum in detail below!
I. When to Plant Chrysanthemum
Planting chrysanthemum usually occurs during Qingming in spring when temperatures start to rise, which can increase the survival rate. In the beginning of spring, chrysanthemums produce many branches, and it is generally recommended to propagate using the division method. These divisions are cut off and placed in a shaded area to dry, then planted in moist soil, which can root well in about half a month.
II. Soil
Planting chrysanthemum does not require a very large pot, and ordinary small clay pots are suitable. The soil can be a mixture of humus soil and sandy loam, 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, and cake fertilizer controlled at 6:3:1.
III. Watering and Fertilizing
Planting chrysanthemum requires ample fertilizer to make the flowers more beautiful. During spring and summer, it can be slightly fertilized with nitrogen every ten days. In autumn, which is the flowering season, a liquid fertilizer should be used once a week after the flower buds appear, and no more fertilizer is needed after the flower buds form.
As for watering, it is generally done when the soil is almost dry, and it should be watered thoroughly at once. Of course, there should be no standing water in the soil, or the roots of the chrysanthemum may rot.
IV. Pinching
When the chrysanthemum grows to about 10 centimeters, pinching can be performed, leaving only 4 to 5 leaves at the base. After new leaves grow, the center is pinched off again. This is done to promote branching and control the plant's height. After pinching, the plant should be pruned, removing weak and dry branches, and keeping 3 to 5 branches.
V. Thinning Buds
In September, chrysanthemums will form buds, and the lower buds should be removed, leaving only the top buds.
VI. Propagation Methods
1. Cutting. First, select full buds, remove the lower leaves, and plant them in the soil, keeping the temperature around 7 to 8 degrees Celsius.
2. Division. The time is usually around Qingming, transferring the divided chrysanthemum to another pot.
3. Seeds. When the temperature is above 10 degrees Celsius, the seeds will germinate, and they can be broadcast from February to April. Under normal conditions, the seeds will bloom.
4. Ground Insertion. Mainly using garden soil mixed with one-third of rice hull ash. If placed outdoors, shading should be done.
5. Grafting. Using yellow wormwood or green wormwood as the rootstock for grafting, which can be done in late April when the seedlings are tall enough.
VII. Disease and Pest Control
During the growth of chrysanthemum, it may encounter diseases such as spot blight, wilt, and various pests. Spot blight is more likely to occur in mid-to-late April and can be sprayed with a 1:1:100 Bordeaux mixture and 50% thiophanate-methyl 1000倍 liquid. Wilt is more severe from early June to July and can be treated by sprinkling lime powder in the potting soil or using 50% carbendazim 1000倍 liquid. Pests appear throughout the year and can be prevented by spraying pesticides appropriately.
The above is a detailed explanation of when to sow chrysanthemum and its planting methods and timing, for your reference and suggestions!
