Why leaves of lettuce pepper wilt leaves fall

Pepper – quite a whimsical culture. At each stage of cultivation, certain difficulties may arise. One of them is the situation when the leaves of pepper seedlings fall. Such a plant reaction can occur on the influence of various factors. Paying attention to the problem is still at the stage when the lower parts of the culture are just beginning to turn yellow.

Inappropriate care

High-quality seedlings are the key to healthy adult plants in the future. For seedlings that are strong and strong, you need to provide them with an optimal microclimate.

If the sprouts have reached a size of 10-15 cm and the lower leaves have turned yellow, this may indicate seedlings are growing. The process is natural and poses no threat. Otherwise, these Symptoms may indicate a culture disease. If you don’t take measures, the peppers may die.

Improper lighting

To seedlings feel great, you must place it in an environment with good light. Diffuse lighting is ideal for seedlings.

It is worthwhile to prevent direct sunlight from falling on sweet peppers – they can cause burns. Especially if there will be drops of water on it that will serve as original lenses. This will also lead to their decline in the future.At peak solar activity, you can shade peppers with newspapers.

Daylight hours for seedlings should be 12 hours. Therefore, in cloudy weather it is necessary to use artificial light with the help of lamps that are installed above the vessels.

Low temperature

The plant was imported from America, so it is not easy to adapt to our conditions. This is a thermophilic culture that reacts sharply to lower temperatures. At indicators below 14 ° C, it ceases to grow. And when lowered to 12 доС at night, it begins to drop leaves. This is due to the fact that the culture does not receive the necessary substances through the roots. Then it begins to feed on the elements contained in the leaves.

After a dive, to which the pepper is very sensitive, the optimum temperature for 3-4 days should be 20-22 ° C during the day and 14 ° C at night. Then you can increase it to 23-25 ​​° C and 18-19 ° C, respectively.

Pepper withers from the heat

When the leaves fall over the seedlings of pepper, it is also worth:

1. Regularly ventilate the room – this has a beneficial effect on seedlings and prevents many diseases.
2. Vessels with seedlings are installed so that they are not in a draft.
3. Do not hold containers on a cold concrete windowsill, then the soil is too cool. Under them, you can substitute wooden boards.Cold air from the window is also contraindicated.
4. Avoid sharp temperature jumps.

If the seedlings are grown in a greenhouse, then with a long cold snap they must be wrapped and covered. They also introduce a large amount of humus, which gives off heat.

To prevent the seedlings from dropping leaves after planting, they should be pricked two weeks before. To this end, you can take out the boxes on the balcony, street or remove the window frame. It is necessary to dose fresh air in moderation so that the development process proceeds gradually. The air temperature for these manipulations should be established constant and not lower than 15 ° C.

Insufficiently nutrient soil

When the lower leaves fall off the seedlings of peppers, one must pay attention to the composition of the soil . Culture has special requirements for it. Improperly selected soil can adversely affect the development of sprouts.

If good light is provided, and the leaves from the bottom turn yellow, this may indicate a lack of nitrogen in the soil. Over time, the plants become too thin and begin to crumble. To prevent its subsidence, it is necessary to make nitrogen-containing fertilizers. It can be such means:

• ammonium nitrate;
• urea;
• complex preparations.

At the stage of yellowing of the lower leaves make top dressing containing potassium, magnesium, phosphorus. If the upper ones also suffered, the composition of the funds should include iron, boron, zinc.

All substances are used strictly according to the instructions, because the excess of elements in the earth is also poorly tolerated by pepper. Before using them, water the soil abundantly so as not to burn the roots. Foliar top dressing in the form of sprayings is carried out in the morning, until there is a bright sun. This contributes to the rapid absorption of nutrients by seedlings. For this purpose, you can prepare such a solution: for 5 liters of water give 1 tsp. ammonium nitrate.

Plants prefer soil with neutral acidity. To neutralize a high pH level, it is liming. To do this, you can make slaked lime, ash, dolomite flour, chalk, cement ash. When preparing the soil mixture, it should be borne in mind that peat increases the pH level.

Improper watering

Plants require timely soil moisture. It is impossible to prevent its drought.

It is necessary to water once every 5-6 days as the top layer of the earth dries. Water should be brought in abundant quantities so that it gets deep. With insufficient watering, only those roots that are under the top will receive moisture. To prevent its delay during arrogant irrigation, it is necessary to make holes in the bottom of the tank. Excess liquid will leave through them.

Water should be settled and well warmed up in the sun (not lower than 25˚С). Watering with cold water also causes yellowing of the seedlings. It is necessary to moisten the soil in the morning or in the evening (if it is not too cold).The basic rule is that water, air and soil should not have very different temperature indicators.

Diseases and pests

Numerous pests

Yellowing, twisting and falling of leaves can be caused by spider mites or aphids when the seedlings are damaged. After all, they gnaw through small holes, suck out the juice from plant cells. The house has created excellent conditions for their reproduction, namely:

• high air temperature;
• low humidity – to increase it, regularly spray water with a spray bottle.

Therefore, at the first symptoms of the disease, it is necessary to examine the plants for the presence of these pests. They can be seen with the naked eye. The spider mite is also determined by the white spider web that appears on the culture. To combat them, you can use a solution of laundry soap, which is used to process all parts of plants. Apply more insecticides. The Aktelik preparation is well suited, which is dosed according to the attached instructions.

The soil is also checked for pests. For this, it is loosened. If insects are found, the soil must be completely replaced. You can disinfect it in a microwave or oven. Also make it steaming.

Other reasons

If all the conditions and rules of care are met, and the leaves of the pepper seedlings fall further, you need to look for other factors of this influence. One of them may be improper development of the root system or leaf plate.

There are times when the roots get confused, their growth and strengthening slows down. Plants then do not receive the necessary nutrition. To correct the situation, it is necessary to transplant seedlings and untangle the roots. The procedure is carried out 3-4 days after watering. They complete it by moistening the soil with room temperature water.

Sometimes a natural process occurs when the central vein grows faster than the leaf itself. If the seedlings are not properly developed, they do nothing.

After planting seedlings in a permanent place, they can also turn yellow and crumble. The reasons for this are different:

1. Plants planted too deep.
2. Incorrect crop rotation was planted after nightshade crops. Their roots release substances into the ground that are toxic to peppers. In this place they can be planted after 3 years.
3. Too thickened plantings – then thinning is worth doing. The optimal distance between plants should be 30 * 40 cm.
4. Shaded beds.

Conclusion

To prevent the leaves from falling off the seedlings of sweet pepper, it is worth doing preventive measures and find out what exactly is the reason. If you follow the rules of care, you can grow healthy seedlings.
