Which month is the best to sow chrysanthemum?

Chinese cabbage has a strong ability to adapt to the environment. It prefers a cool climate and is more sensitive to high temperatures. Its optimal growth temperature range is 17 to 20 degrees Celsius. The growth rate will slow down below 12 degrees Celsius, and poor growth will occur above 29 degrees Celsius. Despite this, chrysanthemum can withstand short-term temperatures as low as 0 degrees Celsius. As for seed germination, as long as the temperature remains above 10 degrees Celsius, the Chinese spinach seeds will begin to germinate, but if the temperature is between 15 and 20 degrees Celsius, the germination speed will be fastest. Let’s learn together which month is the best time to sow Chinese cabbage?

Which month is the best to sow Chinese cabbage?

For protected planting in spring, hotbeds are usually used for sowing and raising seedlings from late March to April. If it is planted in the open field in spring, it is recommended to sow and raise seedlings in a hotbed in mid-April. For direct sowing in the open field in spring, small arch sheds or mulching technology can be used for sowing in early May. As for planting in summer and autumn, you can use cold beds or open fields, and sow in batches, with an interval of 7 to 10 days between each batch.

How to plant chrysanthemum

Seed treatment and germination: 3 to 4 days before sowing, soak the seeds in warm water at 50 to 55 degrees Celsius for 15 minutes, and then continue to soak for 12 to 24 hours. After that, place the seeds in a warm environment of about 25 degrees Celsius for germination. During this period, the seeds need to be washed with clean water once a day to keep them clean. For new seeds, it is recommended to first treat them in a low temperature environment of 0 to 5 degrees Celsius for about 7 days to break their dormancy.

Sowing method: Depending on the planting method (direct seeding or seedling transplanting), you can choose broadcasting or row sowing. When broadcasting, the seed rate is 60 to 70 kg per hectare; when sowing in rows, sow at a row spacing of about 10 cm and use 30 to 37.5 kg of seed per hectare. When raising seedlings in the seedbed in early spring, apply drugs to prevent sudden death disease. The ideal seedling age for seedling cultivation is 20 to 30 days, and when 3 to 4 true leaves grow, it is the appropriate time for transplanting.

Planting tips: It usually takes 5 to 7 days from sowing to germination. During the germination period, be careful to keep the soil moist and avoid drying out. When the seedlings reach 2 to 3 cm in height and have 1 to 2 true leaves, thin out and pull out the seedlings in the field, maintaining appropriate plant spacing. At the same time, shallow tillage operations are carried out. Transplant the seedlings when they grow 3 to 4 true leaves, ensuring that the temperature outside or inside the greenhouse is stable at above 10 degrees Celsius during transplanting. The spacing between plants should be kept at 4 to 6 cm.

Water and fertilizer management: Start watering after the seedlings emerge from the soil. The frequency and time of watering should be flexibly adjusted according to soil moisture. 10 to 15 days before each harvest, apply quick-acting nitrogen fertilizer once, about 15 kg of potassium nitrate and about 8 kg of urea per mu.

Harvesting time: The growing period of chrysanthemum is generally 40 to 50 days. When the plant reaches a height of about 20 cm and has 12 to 13 true leaves, it can be harvested. To maintain the freshness of the product, it is recommended to harvest in the morning and ensure timely harvesting.

In short, chrysanthemum does not require much light and can grow well in a weaker light environment. In an environment with high temperature and short daylight hours, Chinese cabbage is easy to sprout and bloom. However, under long-day conditions, the nutritional growth of Chinese chrysanthemum is often not sufficient.
