How to solve the problem that pepper seeds have not sprouted for 20 days?

Growing peppers is not difficult, but many people do not master the technical points well, and often encounter the situation where pepper seeds take a long time to germinate when growing peppers. So how to solve the problem that pepper seeds have not sprouted after 20 days? Let’s learn more about it below.

1. Seed problem

If pepper seeds have not sprouted after 20 days, there is a high probability that there is a problem with the germination rate of the seeds themselves.

Solution: High-quality pepper seeds should be plump, intact, bright in color, and free of pests and damage. At the same time, conduct germination experiments before sowing and select seeds with strong germination potential and high germination rate.

2. The temperature is not enough

Peppers need higher temperatures to germinate. If the temperature in the environment where you grow peppers is not high enough, the pepper seeds may remain dormant for a long time and fail to germinate.

Solution: The temperature requirements for peppers at different growth stages are slightly different, and 25-28℃ is best during the germination period. Therefore, it is very important to grasp the appropriate time for sowing according to temperature conditions.

3. Insufficient humidity

In addition to a certain temperature, pepper germination also requires appropriate humidity. Generally, the soil moisture suitable for germination is about 80% of the field water holding capacity.

Solution: It is best to soak the seeds for 8-12 hours before sowing. If dry seeds are used for sowing, the seedbed must be watered enough to create a good moisture environment for the seedbed. After sowing, cover with plastic film in time to keep moisture, prevent water evaporation from the seedbed, and ensure sufficient water supply before emergence.

4. Soil issues

Unsuitable soil may also be one of the reasons why pepper seeds fail to germinate.

Solution: Prepare the planting soil reasonably. Generally, you can choose to mix compost soil with appropriate peat soil and river sand. Keep the soil slightly moist so that it will take root and sprout quickly.

5. Planting too deep

If pepper seeds are planted too deep, not only will seed germination be blocked and the root system unable to grow, but it will also directly affect the growth and yield of the plant.

Solution: The sowing depth should be 1 to 1.5 times the length of the seed. In addition, the depth of soil covering should be controlled at 0.5-1.0 cm, and the soil should be gently pressed after sowing. This can effectively prevent the pepper seedlings from emerging from the soil with caps.



In general, the specific reason why pepper seeds have not sprouted for 20 days, in addition to the quality problem of the seeds themselves, is mostly caused by unsuitable planting environment or improper planting operation. Therefore, you only need to solve the problem accordingly.
