How much does a jin of perennial herbaceous chrysanthemum seeds cost? Planting methods and flowering time

Chrysanthemum, also known as Huanghua, Jinying, Taoju and so on, is a relatively common perennial herbaceous plant in China. It is cultivated for its high ornamental and medicinal value. So how much does a jin of chrysanthemum seeds cost? How do you plant them? How long until they bloom?

Seed price:

The price of chrysanthemum seeds is about 40-50 yuan per jin. However, due to differences in seed quality, variety, regional consumption levels and so on, the price can vary considerably, so the local market price should be taken as the standard.

How to plant?

1. Soil selection: When sowing chrysanthemums, choose loose soil rich in organic matter, and apply a certain amount of decomposed organic fertilizer as a base fertilizer before sowing.

2. Sowing method: When sowing chrysanthemums, mix the seeds evenly with a certain amount of sand and scatter them evenly over the seedbed, then cover with about one centimeter of soil.

3. Post-sowing management: After sowing chrysanthemums, keep the soil moist. Germination occurs when the temperature is kept at around 18 degrees C. Make sure there is sufficient temperature, air humidity and sunlight.

4. Timely transplanting: When chrysanthemum seedlings grow 4 to 5 true leaves, they can be transplanted into nutrient pots and pinched. During the seedling growth period, no additional topdressing is needed, so as to avoid excessive growth of branches and leaves that would affect flowering.

How long until they bloom?

Most chrysanthemums open in September, but due to environment and variety, the opening time also varies to a greater or lesser degree. Summer chrysanthemums bloom in May and June, autumn chrysanthemums in September, late chrysanthemums in October to November, cold chrysanthemums in December to January, wild chrysanthemums from June to November, sweet chrysanthemums in May, and small red chrysanthemums from July to October. Of course, through artificial regulation of factors such as light, the flowering period will also change.

The chrysanthemum flowering period is generally September to November. There are many kinds of chrysanthemums, and they are planted across a very wide range of regions. There is no fixed time for them to bloom, but most bloom in autumn, though there are also chrysanthemums that open in summer and winter. Under normal natural conditions, they can be divided by flowering period into summer chrysanthemums (blooming May to September), autumn chrysanthemums (blooming October to November), and cold chrysanthemums (blooming December to January), generally lasting about 20-35 days. But through the cultivation of horticulturists, by changing sunlight conditions, there are also May chrysanthemums that bloom in May, July chrysanthemums that bloom in July, and August chrysanthemums that bloom in August.

Cultivation techniques:

1. Potting soil: For chrysanthemum cultivation, choose fertile sandy soil, starting with a small pot and then a larger one, repotting 2 to 3 times, and the pot can be set in July. For setting the pot, a mixed soil can be made from 6 parts leaf mold, 3 parts sandy soil and 1 part cake fertilizer residue. After watering thoroughly, place it in a shady spot, and once the plant grows normally, move it to a sunny spot.

2. Watering: In spring, when the chrysanthemum seedlings are small, water sparingly. In summer, when the chrysanthemum seedlings have grown, water once in the early morning and again in the evening, and use a watering can to spray water on the chrysanthemum branches and leaves and the surrounding ground to increase environmental humidity. Before the Start of Autumn, water and fertilizer should be appropriately controlled to prevent the plant from shooting up and growing wildly. After the Start of Autumn and before flowering, increase the amount of watering and begin fertilizing, gradually making the fertilizer solution stronger. In winter, the flowering branches basically stop growing, the plant's water consumption decreases markedly, and evaporation is also small, so watering must be strictly controlled.

3. Fertilizing: When the chrysanthemum plants are planted out, sufficient base fertilizer should be applied in the pot. Afterward, a nitrogen fertilizer can be applied once every 10 days. After the Start of Autumn, from flower bud formation to visible buds, apply a slightly stronger fertilizer solution once a week. When the buds are about to open, apply one more strong fertilizer solution, and then pause fertilizing. If at this time the chrysanthemums can be given one application of superphosphate or 0.1% potassium dihydrogen phosphate solution, the flowers can open more brightly.

4. Pinching: When the chrysanthemum plants grow to more than 10 centimeters tall, begin pinching. When pinching, leave only 4 to 5 leaves at the base of the plant, and remove all the upper leaves. When 5 to 6 new leaves have grown, pinch out the growing tip again, so that the plant retains 4 to 7 main branches. Branches and buds that grow later should be removed promptly. Pinching can cause the plant to branch, effectively controlling plant height and plant shape. At the last pinching, carry out shaping pruning of the chrysanthemum plants, removing excess branches, overly vigorous branches and overly weak branches, and keeping 3 to 5 branches.

5. Bud thinning: When chrysanthemums form buds in September, remove the buds at the lower part of the plant, leaving only one bud at the top of each branch.
