Treatment of succulent sunscreen and sunburn

Sunburn is one of the sad stories about meat that happens every spring. What? Do you get sunburn in spring?

The state after sunburn

The meat spent the winter in a comfortable room, after months of lack of sunshine, suddenly ushered in spring, everyone was ecstatic to take them outside for the baptism of the sun, and then the tragedy happened. The sun in spring is very strong, and this sudden change in the environment is very fatal to plants. Therefore, we should not only pay attention to sunscreen in spring, but also do some appropriate sunscreen measures in summer and autumn.

Someone must ask: why don't you need a sunshade net in the greenhouse? Family maintenance is completely different from greenhouse. The greenhouse is almost full-day environment, succulent long-term in such an environment has been adapted to high-intensity sunshine, so even without sunshade is no problem. The environment at home is very comfortable, the sunshine is not enough, and the strong sunshine which suddenly changes due to the climate is very easy to burn the leaves.

There are many ways to prevent sunburn. You can refer to the following in your home environment:

1. Avoid suddenly moving from weak sunlight to strong light exposure.

two。 The glass will block some ultraviolet rays, so there is no need to move behind the window, nor after the screen or mosquito net.

3. In some areas with strong sunshine, sunscreen needs to be pulled, and the density can be determined according to the light intensity.

4. While protecting yourself from the sun, you also need to pay attention to two other conditions: sunny days after heavy rain or exposure to the sun after watering, both of which can cause succulent plants to die suddenly. After the moist soil is exposed to strong sunlight, the inside of the flowerpot begins to heat up, and the water evaporates to form a sauna effect. The succulent roots will soon be steamed to death, and then the whole plant will rot. Therefore, after entering the summer, watering must be chosen at night or on cloudy days to avoid watering in the hot sun and sunny days.

Treatment after sunburn

Sunburn does not show up from the plant leaves on the same day, it may be a variety of scars in the following week, so it is not too easy to find. The sun suddenly became strong, and the succulent leaves softened or even collapsed in direct sunlight. Such a situation requires attention. Once there is a similar situation of possible sunburn, we need to deal with it in the following ways.

1. Move to a position where the sun is relatively weak (astigmatism), or pull up a sunshade net.

two。 Add some ventilation appropriately to avoid the muggy environment.

3. If the soil is particularly dry, it can be watered 2-3 days after moving to the astigmatism to ensure that the plant can absorb water normally to restore health.

4. The burned leaves should not be broken off because they are ugly. Nutrients are still stored in the leaves. Succulent plants will first consume the nutrients of these disabled leaves during the recovery period.

5. For some burns that are particularly serious, they need to be dug up, cleaned, dried and replanted. The soil during the convalescent period had better be as soft and water-retaining as the soil for raising seedlings.

6. If you like outdoor care, you don't have to move even if you get sunburned. Maintain the present environment, and plants will slowly exercise themselves to adapt to this sunshine intensity. Usually maintenance adopts a small amount of frequent watering to avoid decay caused by excessive evaporation of water. More ventilation to cool plants and soil. (this way of exposure is not suitable for seedlings, and there is a certain possibility of dying in the sun.)

7. All succulent plants after sunburn, the leaves themselves will not recover, can only wait for the center of the plant to grow new leaves, consumption of sunburned leaves to restore beauty.

The damage and recovery rate caused by sunburn vary depending on the variety of succulent plants.

I. the genus Phellodendron of Sedum family

These leaves are very thin, and if they suddenly move from a relatively weak position to a strong sun without strong sunlight training, this will happen in the picture below. Is there a feeling that I didn't wake up... The leaves did not change much in the first two days of sunburn, but three or five days later, scars appeared one after another. Fortunately, the speed of replacement of leaves such as lotus palms is very fast, and it can be recovered in about two weeks after normal maintenance. the sunburned leaves slowly dry up and fall off, and new leaves grow from the center.

2. Sedum of the family Sedum

This kind of group is very easy to grow in large groups, so there is often sunburn in the heart of the leaves. Unlike other varieties, it is troublesome to recover from sunburn. So you need to remove the sunburned leaves with tweezers to create new growth points. The speed of recovery is relatively slow. During the recovery period, we must pay attention to hydration to speed up the recovery. It doesn't matter to get astigmatism to grow a little longer.

3. The genus Euphorbia of Sedum family

Rosettes are generally prone to sunburn on the edge of the leaves, which looks pretty good after sunburn. Such as as long as the normal maintenance and slow recovery of good! Attention should be paid to frequent and small amount of watering in the later maintenance to avoid dampness and rot. If there are flowers and arrows sticking out, they can be cut off so that plants can preserve more nutrients to restore their bodies.
