Why do the newly grown leaves wilt and then wither?

Fresh and young leaves wilt may be due to too much sunlight, especially in summer. If you leave it in bright light at this time, it will get sunburned.

leaves, new leaves will wilt first. Attention should be paid to shading treatment, and strong light must not be exposed to the sun, otherwise it will be easy to get sunburned. It may also be due to overwatering, the respiration of the roots is blocked due to the large amount of water, and the leaves will wilt or even turn yellow and wilt.

Water treatment should be controlled, more ventilation should be used to allow the water to evaporate as soon as possible, and then apply Bicagen Cong Cong to prevent root rot.

Usually watering is a bit of a root, the root growth of the plant is not good, the plant can not absorb water and nutrients, and the new leaves will be like this. Put it in a bright place indoors, dry and watered, the soil is not dry and do not water, it doesn't matter if the soil is dry, add some nutrient solution when watering, and the leaves are often sprayed with potassium dihydrogen phosphate, and the plant grows better and more vigorously.

The newly grown leaves are flooded and then wilted because there are not enough nutrients. It all depends on the nutrients of his pole, and it grows to a certain extent.

The crowd looked for him, and suddenly looked back, but the man was in the dim lamp. The core of the truth seems to be within reach, you see the peaks and loops, you see the streams, you see the breeze and the moon, you see the sky and the clouds, you don't have to be melancholy, you don't have to sigh, life is complete.

It can make the leaves of the plant appear local yellow and dry, and finally make the plant die, mostly distributed in the leaf veins, resulting in the leaves drying up, I have a few pots of anthurium are dead, because there is a period of absence. Manual control: In the process of cultivating flowers, if it is found that there are individual branches or leaves with scale insects, they can be gently brushed off with a soft brush, or combined with pruning, and cut off insect branches and leaves.

It is required to be brushed, cut, and burned in a centralized manner, and do not litter.

Pesticide control: according to the various occurrences of scale insects, spray pesticides in the peak stage of nymphs. Therefore, most nymphs hatch for a short time, the body surface has not yet secreted wax, and the shell has not yet formed, and it is still easy to kill with medication.

Spray once every 7-10 days, 2-3 times in a row. It can be sprayed with 40% dimethoate 1000 times, or 50% malathion 1500 times, or 255 imithion 1000 times, or 50% dichlorvos 1000 times, or deltamethrin 3000 times. Protection and exploitation of predators:

For example, the Australian ladybug, the big red ladybug, the golden aphid wasp that parasitizes the shield scale, the soft scale aphid wasp, and the red-spotted lip ladybug are all effective natural enemies, which can be used to control the harm of scale insects, and should be reasonably protected and utilized.

Hello, it is mainly caused by the lack of light and poor air circulation. If you keep putting it down, the whole plant may die. It's best to figure out what kind of plant it is, whether it likes shade or yang.

Those who like the sun should often let it bask in the sun in order to grow healthily. As long as the yin-loving ones are often put in the hallway, it's fine.

If only the bottom leaf is withered, it belongs to normal metabolism. The plant absorbs nutrients from the old leaves to supply the growing point, and if the whole plant appears, it may be due to low water supply, atrophy, or too high temperature, and the root system does not absorb enough water.

Pay attention to watering control. It is necessary to see the dry and the wet.

So-called"See Dry"It means that after watering once, wait until the soil surface is white, and the surface and internal soil moisture disappear, and then water the second time, and you can't wait for the potting soil to dry for a long time before watering. The general method is to put your finger inside the soil and feel it dry before watering. If the inside is wet, it is not suitable for continuous watering, which is easy to cause water accumulation in the lower part of the soil, which will seriously lead to root rot.

So-called"See wet"It means that every time you water, you have to water thoroughly, that is, until there is water seeping out of the drainage hole at the bottom of the pot, and you can't water it"Half cut water"(i.e., wet at the top and dry at the bottom), because the roots of a pot of vigorous plants are mostly concentrated at the bottom of the pot and watered"Half cut water"In fact, it is equivalent to not watering.

Adoption"See dry and wet"The method of watering not only satisfies the water required for the growth of such plants, but also ensures the oxygen required for root respiration, which is conducive to the healthy growth of plants.

If there is wilting, you should stop watering immediately, and then put it in a well-ventilated place, away from direct sunlight, and apply fertilizer once a week.

Hope it helps.

The leaves of the plant are wilted, probably because of the lack of water, so it should be replenished in time to change the situation.

Because you can't pour it with coke.
