With proper sowing of pepper seeds for seedlings, the leaves on it will not turn yellow. If yellowness nevertheless appeared, it is necessary to find the reasons for this phenomenon. They may be the following.
Soil composition
Heavy, dense, highly acidic soil can cause yellowing of seedling leaves. Peppers are very picky and prefer light, loose soil with neutral acidity. I recommend preparing a soil mixture for planting peppers from: peat, humus, soddy soil, sand and hardwood sawdust
Wrong watering
Seedlings need watering with warm, settled water with a temperature of 25 ° C. Violation of the temperature regime, overdrying of the soil or excess moisture can harm pepper seedlings.
Illiterate pick
Pepper seedlings have a very vulnerable root system, so with the slightest damage to it, the leaves begin to turn yellow. In this case, I recommend monitoring the survival of seedlings and, if the yellowness does not disappear, apply growth stimulants.
Wrong lighting
During the growth of seedlings, seedlings need to be illuminated 12 hours a day, so artificial lighting is necessary. Depending on which side of the world the windows in the apartment face, it is not recommended to put the seedlings on the windowsill so that direct sunlight does not fall on the boxes with sprouts
Nutrients
Excess or lack of nitrogen leads to yellowing of the leaves. When a white coating appears on the drainage holes, it is necessary to spray the seedlings with a weak solution of ammonia
Diseases and pests
Very rarely, seedlings at home are affected by diseases or pests. In this case, dusting the seedlings with tobacco or spraying them with soapy water is required.
Prevention
It is best to prevent an unpleasant situation with yellowing leaves on pepper seedlings than not to expend efforts on combating this phenomenon, especially since the cause is not always possible to identify accurately. Prevention measures include:
- Careful processing of containers for planting seeds with soap solutions and soda.
- Disinfection of soil and seeds before sowing with a weak solution of potassium permanganate or buying already disinfected ones.
- Proper illumination of seedlings.
- Initially, try to plant each seed in a separate container so as not to pick.
- Follow the watering schedule so that the topsoil is always moist.
Most often, with the correct determination of the cause of yellowing of the leaves, you can correct the error, save the seedlings and, accordingly, the harvest. I advise you to initially carefully follow all the rules for planting seeds and carefully monitor the seedlings and seedlings of pepper, then you will get a decent harvest without additional effort and time.
