How to repair the leaves of the orchid, and how to manage it next

Remove the rotten leaves... Winter management Orchid is native to South Africa, is a perennial evergreen herbaceous flower, likes warm and cool climate, is afraid of high temperature and cold, dormant in summer, and grows in autumn and winter, therefore, strengthening winter management is the key to cultivation. The main points are as follows: 1. Fertilizing Junzi orchid has the fastest vegetative growth rate in winter and needs the most nutrients, so it is very important to apply winter fertilizer.

Before entering the flower pot, use bone meal, fried sesame seeds, cooked soybeans, etc. or compound fertilizer, and water once every 15 to 20 days, and you can also use animal and plant residue soaking solution to water the roots. It is necessary to apply fertilizer to prevent damage from thick fertilizer. Second, watering Junzi Orchid is a fleshy root, and it is good to be afraid of water stains.

In addition, the leaves of the orchid have a waxy layer, and the temperature is low in winter, and the transpiration and evaporation of water are low. Therefore, watering should not be too much, just combine fertilization and watering to keep the potting soil moist. Do not soak in large amounts of water, resulting in rotten roots and dead seedlings.

3. The most suitable growth temperature for thermal insulation is 15 to 25, 10 stop growing, 0 suffer from frost damage. Therefore, it is necessary to keep warm and freeze in winter. After the flower stem is extracted, it is advisable to maintain about 18.

The temperature is too high, the leaves and flowers are slender and thin, the flowers are small and of poor quality, and the flowering period is short; The temperature is too low, the flower stem is short, and it is easy to pinch arrows prematurely (flowering), which affects the quality and reduces the ornamental value. Fourth, the dimming gentleman Lan likes to scatter light, and avoid direct strong light. For indoor maintenance in winter, the pot should be placed in a sunny place.

In particular, there should be good light before flowering, which is conducive to the development of flower buds. After flowering, it is beneficial to prolong the flowering period by appropriately cooling down, avoiding strong light, and maintaining good aeration. Fifth, the leaves are fat and strong, the leaves are green and bright, and the leaves are short, wide, thick, green, bright and quite are the characteristics of healthy Junzi orchid, which is the basis for promoting flowering and improving ornamental value.

To maintain a strong leaf quality, in addition to providing reasonable fertilizer and water, it is necessary to keep the leaf surface clean to improve photosynthetic efficiency. The method of leaf protection is to wash the leaves regularly, spray and rinse with the same water or wipe the dust on the polluted leaves to keep the leaf surface clean; The second is to spray fungicides in time to prevent the occurrence of leaf spot, leaf blight and stem rot, and ensure that the leaves are green and the flowers are gorgeous. Satisfied.

Injured leaves won't recover, you can cut off a portion and wait for new leaves to grow.

If the leaves are wilted due to overwatering, we can put it in a well-ventilated place, if there is too much water and we need to clean it up manually, we can use newspapers and the like to absorb the moisture on the surface, and then replace some dry soil to increase the absorption of moisture. If the potting soil has not been watered for a long time and the potting soil is too dry, we should put it in a cool place, and when the potting soil returns to room temperature, we can water it thoroughly and see that there is water flowing out from the bottom of the pot.

It is generally caused by improper maintenance. For example, there is a problem with watering, the light is not suitable for the change of seasons, the nutrients cannot meet the growth of the plant, and the phenomenon of root rot occurs.

Light problems: The growth of Junzi orchid likes a semi-shady environment, and a long time without light or a long time out of too strong light will cause the leaves to wilt and droop and be dull. Therefore, it is very wise to find a semi-shady environment with sufficient scattered light to breed Junzi Orchid, and the direct sunlight time should not exceed 4 hours every day, and it is best not to shine in the sun at noon.

So let's find a suitable place to breed Junzi orchid on the balcony in the north, in the area north of the Tropic of Cancer in our country, the balcony in the north receives the shortest amount of sunlight. It is conducive to the growth of Junzi orchid.

Nutrient loss: Giving enough nutrients in spring can promote the rapid growth of Orchid. We can fertilize it every half a month in the spring.

In summer, the plant will enter a short period of dormancy, and the high temperature is also prone to fertilizer damage, do not apply more fertilizer at this time, so as not to cause the concentration of fertilizer to increase due to the rapid evaporation of water and burn the roots. Therefore, in the summer, you should apply thin fertilizer, and you can apply fertilizer every other month.

Root rot: Once a similar situation is observed, we need to remove it from the soil, clean the roots with water, prune off the roots that have rotted, soak them in potassium permanganate solution for a few minutes, and then put them in a cool and ventilated environment to dry the wound before repotting. After that, maintenance needs to pay attention to watering to see dry and wet, fertilization is not used temporarily, and the light can be semi-shaded.

If it is only a small area of sunburn, the sunburned part can be cut off, although it will leave a small hole, but it can avoid rotting and causing infection of the leaves. If the sunburn is on the edge of the leaf, or the tip of the leaf, you can cut off the sunburned part directly. If the sunburn is very large, you can directly cut off this leaf, sometimes the sun is more serious, maybe all the leaves have sunburn, then you can directly cut off all the leaves, so that the Junzi orchid can re-emit the leaves.

Note: If all the leaves of the gentleman are cut, watering must pay attention to avoid watering to the center of the leaves, otherwise it is easy to cause rot, and also pay attention to water control, so as not to cause rotten roots due to water.

Put it in a cool place and give it slowly, it won't die. The leaves will wither.

Leaves that are too badly sunburned are removed directly. Pay attention to maintenance in the future.

Don't worry about it, just update it naturally.

This led to the creation of "sleepiness". Correspondingly, the reason why drinking coffee can be refreshing is that the main kick or intention of coffee is to kick the opposing player.

Orchid is native to South Africa. Sexual preference for warm, humid, semi-shady environment, afraid of strong direct sunlight, but not cold-tolerant. Fertile, loose, well-ventilated and slightly acidic soil is required.

It is not tolerant to water and humidity, and has a certain drought tolerance. As long as the Junzi Orchid does: avoid the wind in spring, avoid the sun in summer, prevent rain in autumn, and do not dry in winter, you can keep the plant growing well, and the flowers and leaves are luxuriant.

According to you, the orchid suffers from sunburn: yellowing, zooming of the leaves, caused by prolonged exposure to direct sunlight in summer. Shading measures should be taken immediately, the yellowed scorched leaves can be cut, and the slurry on the broken leaves should be thoroughly wiped off with absorbent cotton trembling at the cutting edge.

Be especially careful when watering, stop fertilizing at this stage.

You can rub the leaves of the orchid with beer or white vinegar and wipe it gently.

The reason for rubbing the leaves of Junzi orchid with beer: beer contains a small amount of alcohol, which can remove the dirt and dirt that hinders the stomata of the leaves, so that the leaves can breathe smoothly and play a sterilizing role; Beer also contains ingredients such as protein and amino acids, which can be absorbed directly by the leaves, similar to foliar fertilization.

The original reason for using white vinegar: white vinegar mainly plays the role of decontamination, and the dirt on the leaf surface not only affects the ornamentation, but also is not conducive to light and effect. However, attention should be paid to the mature orchid, especially the flowering and fruit-setting junzi orchid, when spraying vinegar water, it is necessary to protect the leaf core and false bulb to prevent the decay of the water when spraying vinegar water.

Junzi orchid is a semi-positive flower, like relatively weak scattered light, not tolerant to strong light, too strong light is easy to cause sunburn, light leaves from green to yellow, heavy leaves dehydrated and dry death. Short days in winter and spring are more conducive to flowering. Good light is an important condition to ensure that the gentleman's orchid is large and colorful.

However, if the place is placed in too dark light, the long-term lack of light will also cause the leaves to lose their luster, the old leaves will be dark green, and the new leaves will become thinner and yellow or yellow-green (shade yellow). At this time, the orchid should be moved to a slightly stronger place or supplemental light. The leaves of the orchid have phototaxis, and they should be stocked to the light in order to maintain the shape of a line on the side and a fan on the side.

Solution: Mainly because the direct sunlight is too strong, it is necessary to shade the Junzi Orchid and water it in time.

Generally, the leaves burned by the sun will dry up for a long time, affecting the ornamentation, which is a headache, no matter how many leaves are serious new leaves above, only put the shade and light in a little place to raise the best.

What should I do if my orchid leaves are sunburned? Do so, the longer the better.
