Next you will see a photo of the twisted leaves of pepper seedlings:
The reasons
Twisting can occur due to several factors:
- Uneven growth. The median vein is ahead of the rest of the leaf plate. Sheet becomes "corrugated", folded with a boat. Alarm is not worth it. The leaves of seedlings will level themselves as they grow.
- Lack of essential trace elementsmost often potassium, phosphorus. The lack of phosphorus is manifested in a change in the color of the leaves of the seedling, the stem. The leaves curl, first turn blue, and then acquire a black and purple color.
- Violation of agricultural technology. Temperature, water, light modes are not observed.
- Aphid spider mite. When infected with aphids on the leaves appear red spots. The offspring of aphids tolerate freezing temperatures. It is activated and multiplies in the spring. The tick entangles the plant with a web. The larvae damage the root system. Due to a lack of nutrition, the foliage turns yellow, fades, and falls. The seedlings weaken, the stem breaks off the ground, the pepper perishes.
- Viral disease peak rot.
Are fighting
With a lack of potassium, seedlings need to feed.
- Sprinkle with wood ash. Half a cup of wood ash to pour on the moist soil around each plant.
