When Is the Best Time to Start Chili Pepper Seedlings
SummaryChili pepper seedlings are generally started in mid-to-late February. In the south, the seedling period is about 90-100 days, while in the north it is about 60 days. Because climate conditions vary across China, the specific sowing time differs from region to region. In North China and Northeast China, the sowing time is generally February to April; in the middle and lower reaches of the Yangtze River, the sowing time is generally October to November; and in South China, the sowing time is generally December to January of the following year.
I. Chili Pepper Seedling Time
Generally, chili peppers are started in mid-to-late February. In North China and Northeast China, the sowing time is February to April; in the middle and lower reaches of the Yangtze River, sowing is done in October to November; in South China, sowing is done from December to January of the following year. The seedling period in the south is about 90-100 days, and in the north about 60 days.
II. Choosing a Seedbed
1. The chili pepper seedbed should be planted in soil with plenty of sunlight, deep and loose soil, convenient drainage and irrigation, and shelter from the wind. It should not be planted in soil where the previous crop was chili peppers, potatoes, or similar crops.
2. If the seedling trench is too wide or too long, it will affect the normal growth of the seedlings. Therefore, the planting area can be controlled according to the specific planting quantity. To ensure the nutrients needed for plant growth, nutrient soil can be prepared by mixing farmyard manure, carbendazim, field soil, and so on. This is more conducive to seedling growth and can also prevent seedling-stage pests and diseases.
III. Soaking Seeds to Promote Germination
1. Chili peppers are generally grown mainly by sowing and raising seedlings. Before sowing, soak the seeds in clean water for about 8 hours, then remove the seeds and drain them, wrap them in a wet cloth, put them in a plastic bag, and place them in an environment at room temperature of about 30°C to promote germination.
2. During germination, turn the seeds appropriately every day so they can be heated evenly. After about 5 days, when about 75% of the seeds have sprouted, they can be sown.
3. Note that the soaking time should not be too long, as this can easily cause nutrient loss and thus affect the germination rate. If the soaking time is too short, the seeds will not absorb enough water, which will also reduce the germination rate.
IV. Sowing at the Right Time
1. Before sowing, water the seedbed thoroughly. Once the water has penetrated into the soil, sowing can begin. Chili peppers are generally sown mainly by broadcasting.
2. First, evenly broadcast the seeds on the seedbed, which helps promote uniform emergence. After sowing, to prevent diseases during the chili pepper seedling stage, chemicals such as Miaojundi can be mixed with soil and spread over the seeds, then cover with about 1 cm of nutrient soil. To improve the seedbed's heat preservation and moisture retention capacity, a layer of plastic film can also be covered, which helps increase the seed germination rate.
V. Later Management
1. After sowing, the daytime temperature should be controlled at about 22°C, and the nighttime temperature should be kept stable at about 10°C. If the emergence rate reaches about 65%, the plastic film can be removed. If the temperature is too high, ventilation should be strengthened to lower the temperature in order to prevent seedling scorching.
2. During growth, if the soil is relatively dry, water it in time, but do not overwater. When the seedlings grow 2 true leaves, to increase the space for seedling growth, thinning should be carried out appropriately, keeping only the robust seedlings.
3. To allow the seedlings to adapt to the external environment, hardening off can be carried out about 15 days before transplanting, thereby increasing the survival rate.
