What s going on with the tip of an orchid s leaf drying up?

There are many reasons for the dry tip of the orchid leaves, the common one is that there is a problem with the roots, if it is a newly potted orchid, as long as it is normal maintenance, it is basically a normal orchid weed, and the orchid has requirements for the maintenance environment, especially ventilation and humidity, and the humidity is not enough to cause the leaves to turn yellow and dry the tip.

The orchid has a beautiful plant shape, long leaves, dark green and shiny leaf color, and beautiful flowers, giving people a fresh and elegant feeling, so it is deeply loved by the majority of flower friends. However, in the process of breeding, orchids are prone to dry leaf tips, what is the reason? Let's give you a detailed introduction:

Let's take a look at the **:

The picture above is a potted orchid maintained by netizens, according to netizens, the leaves of orchids have been showing the same dry tips as in the picture above, I always thought it was a problem with the root system, and the inspection found that the root system of the orchid is very normal, and there are crystal heads.

Normal watering and maintenance, no rotten roots, no empty roots, and crystal heads, that is, the leaves have been dry and sharp, this situation is generally due to the environment, such as poor ventilation, insufficient humidity, exposure to the sun and other reasons, but look at the ** provided by netizens, and then look at the degree of yellowing and dry tip of the leavesApparently a normal orchid has retired.

The so-called orchid weeding is that when the orchid is potted or maintained normally, the old leaves of the orchid slowly reced, the new leaves are normal, and the young leaves slowly grow, and the old leaves are dry and yellow, and then gradually fall off.

Orchids themselves are more fertiliser-loving, but if you apply too much fertilizer, the leaf tips will dry out, and the leaves will also appear dark spots. Then you need to put it in a well-ventilated place, and then water it until the water flows out, so that the fertilizer can be diluted.

Is there a downside to orchids? For the newly potted orchids, it is normal to have weeding, if the weeding has been retiring will affect the later rejuvenation, the weeding should pay attention to adjusting the maintenance method, for the orchids that have been potted, the orchid weeding is about to grow new shoots, so it is also a good thing.

The tip of the orchid leaves is dry and yellowish because of low temperature frost damage or lack of fertilizer, and the suitable growth temperature of orchids is 20 to 30 degrees Celsius, below which it is easy to get frostbite.

Orchids are not tolerant to cold, so don't let them be hit by late frost when the temperature drops down in late autumn, and should be placed in a leeward and warm place, otherwise it will easily cause the leaf tips to dry up or the leaf color to become light and yellow.

The leaf tips of pests and diseases suddenly turn yellow and dry up, you can check whether it is a problem with pests and diseases.

First of all, the soil is dehydrated, and if the soil is deprived of water, it will cause the leaves of the plants to turn yellow and dry up.

Secondly, insufficient or too much watering, if the plant is not properly replenished with water, it is easy to cause the leaves to turn yellow and dry. Then metabolism, yellowing and drying of plant leaves is a phenomenon of natural aging, which belongs to normal metabolism.

There are also roots that grow out of drainage holes, which are not repotted in time. Or if you apply too much fertilizer, if you add too much fertilizer to the plant, it will cause the plant to be injured, which will make the leaves yellow and dry.

1. Environmental mutations lead to yellowing of orchid leaves: environmental mutations include environmental changes when turning over, turning pots is very good for orchids, but if they are not repotted properly, they will cause orchids to not adapt, resulting in temporary yellowing of leaf tips. Workaround:

At this time, it is best to repot and make sure that the orchid root system is intact.

2. Long-term lack of water leads to yellowing of orchid leaves (drought yellow): caused by lack of water and drought, it is characterized by the leaf tips of the old leaves from the bottom to the top of the first yellow, if the lack of water for a long time, the whole plant will be yellow, and even die. Workaround:

It should be watered in time, but not too much at one time, first water a small amount of water, and gradually increase the amount of water.

3. Yellowing of orchid leaves due to air drying: Orchid leaf tips turn yellow, and the new shoots are smaller, which may also be caused by dry air. Solution: Orchids prefer a ventilated environment, and it is best to transplant them to a well-ventilated place.

The leaves of orchids are yellow and dry, which may be the reason why the soil is not breathable or alkaline, and can be prepared into new soil for cultivation with humus, sandy soil, garden soil, bone meal, etc.

It may also be the cause of lack of water, and the orchid should be watered in time, and gradually return to normal after absorbing water. It may also be the cause of too much light, which can be done in summer. Or it may be the cause of too much water and fertilizer to hurt the roots, and the amount of water and fertilizer should be controlled.

When cultivating orchids, if the soil is compacted and not breathable, the clay is not permeable, or the soil is alkaline, the normal growth is restricted, which will lead to poor growth of the orchid, so it will cause the leaves to turn yellow and dry up.

1.Due to lack of water, caused by drought, it is characterized by the old leaves from the bottom to the top of the first yellow, if the lack of water for a little longer, the whole plant yellow leaves, or even death, should be watered in time.

2.The planting material is not breathable, the root system is not breathable, and the nutrient absorption is not good, and the resistance of the orchid is weak, and the reaction on the orchid is the yellow tip. Pine needles, chaff, bark, peanut shells, grass and other planting materials are added to the potting soil, which is equivalent to base fertilizer or base fertilizer.

3.Excessive fertilization will also cause leaf tips to dry out, so it is better to apply less than too much; It is better to apply lightly than thickly; Organic fertilizers and chemical fertilizers are cross-used to avoid single application.

4.No shade and ventilation. The key to cultivating orchids is not to let the sun shine directly on the orchids.

On the one hand, it is to avoid dehydration and sunburn of the orchid leaves, and on the other hand, it is to cool down the orchid. Place orchids in a north-south transparent place, open doors and windows, and allow indoor and outdoor air circulation, ventilation can reduce the occurrence of orchid diseases.

Extended Links. History of orchid cultivation.

Orchid (Cymbidium spp.).) is the general name of some terrestrial orchids of the genus Orchidaceae. It is a famous perennial herbaceous flower, also known as maid flower, swallowtail spring. "The Book of Yuejue" has a record of the king of Yue Goujian planting orchids in Zhu Mountain.

In ancient texts, Lan Hui often said that the difference between the two, according to the description of Huang Tingjian (1045 1105) in the Northern Song Dynasty, Lan Hui is clustered, and the sand and gravel are luxuriant; Poured with soup and tea is fragrant, it is its similarity, to its flowers, a dry flower and a flower and the fragrance is more than the orchid, a dry five seven flowers and the fragrance is not enough. The Ming and Qing dynasties were the prosperous period of orchid cultivation, and the "Minbu Shu" mentioned that the cultivation of Jianlan in the four counties of Fuxing was particularly prosperous, and the Jianlan that was widely spread by the people was different from the wild species in the mountains. Since the Qianlong period of the Qing Dynasty, Jiangsu and Zhejiang have gradually become the center of orchid planting, and the flowers in Shanghai, Suzhou, Jiaxing and other places will be quite prosperous.

During the Jiaqing period, some farmers in Yuyao, Zhejiang Province had mastered the method of orchid cultivation and took the cultivation of orchids as their business. At that time, the gentry who loved Lanhui were everywhere, and the treasures they collected were worth hundreds of gold, even tens of thousands of gold.

40 species of orchids were described, mainly Jianlan. Among them, the famous ones are Chen Mengliang, Jin Lingbian, and Yu Squid Orchid. The book makes a comprehensive discussion on the geographical location selection, soil preparation, and orchid separation technology of Yilan, and points out that those who are good at raising flowers must take care of their leaves, and Ye Sheng will not worry about its flowers, emphasizing that different varieties should use different fertilization and irrigation methods.

The Ming "Orchid Spectrum Law" mentioned that mountain soil must be used to plant orchids, and proposed measures to delete flowers and turn pots. "Zunsheng Eight Notes" mentions that there are four precepts for raising orchids: "Spring does not come out, summer does not day, autumn does not dry, and winter does not get wet."

It is still used as a reference by Yilan people. In the Qing Dynasty, Yilan wrote the most extensive, and the orchid cultivation techniques recorded were even more complete. According to the color of orchid bracts, the shape and size of sepals and the color of lip petals, books such as "Miscellaneous Notes on Yilan" and "Notes on the First Fragrance" divide orchid into plum petals, narcissus petals, lotus petals, super petals and plain hearts.

He also created a large number of vocabulary and special terms for the morphological structure and biological characteristics of orchid flowers. These achievements are still valued by the horticultural community today.

Yellow leaf tips may be caused by lack of water, rotten roots, low ambient temperature, and too much light.

Orchid is a plant suitable for breeding in a humid environment, insufficient water will cause the leaves to turn yellow, starting from the tip of the leaf, from top to bottom, gradually turning yellow, so it is necessary to replenish water in time.

When cultivating orchids, they need to be kept in a warm environment, and if they are kept in a low temperature environment for a long time, they will also cause the leaves to turn yellow.

The reason for the yellowing of the tip of the orchid leaves may also be due to too strong light, long-term exposure to the sun, and too high temperature to cause leaf burns. Let it acclimatize to the ambient temperature.

What causes the tip of the orchid leaf to turn yellow and black?After listening to it, I finally understood.

Orchids often dry up the leaf tip, and even the whole leaf wilting phenomenon, the first orchid flower friends do not know what to do, the orchid leaf tip dry is mainly due to orchid anthracnose and round spot disease, orchids suffer from frost damage or late frost damage, it is also easy to form leaf tips dry or discolored, let's look at the specific solution.

One is caused by orchid anthracnose and round spot disease. This disease occurs in large numbers during the rainy season or during the summer and autumn seasons when it is hot and rainy. The solution is to spray 50% carbendazim 1000 times or 50% clomedan 500 times solution in the prone period, 1 time in 10 days, 3-4 times in a row.

In addition, when orchids suffer from frost damage or late frost, they are also prone to dry up or discoloration of leaf tips. Therefore, in areas where the temperature is below 0 in winter, the orchids should be moved indoors for ventilation and maintenance in a sunny place before winter. When moving outside in spring, take care to avoid the damage of late frost.

The traditional test of "no wind in spring, no day in summer, no dry in autumn, and impure and pure burial in winter" is good for preventing the drying up of orchid leaves.

For the orchid leaves that have dried up at the tip of the leaves, if the situation is not too serious, you can use manual pruning, and cut it off about 10 mm below the dry part with scissors (preferably sterilized with alcohol) according to the shape of "", so that it can still keep the full pot green, and it is better to spray fungicide after pruning.

Note: "Spring is not windy, summer is not dry, autumn is not dry, winter is not wet" means that spring should not be moved too early to avoid strong winds;In summer, it is necessary to provide proper shade to prevent scorching sun exposure;In autumn, it is necessary to water frequently to prevent drought among ants;In winter, the potting soil should not be too wet to prevent freezing and root rot.

The orchid leaves are dry and tall, that is, the orchid has withered leaves, and the main reasons are as follows:

1. Overwatering: Although orchids like a humid environment, they should never be overwatered to cause rotten roots and dead leaves.

2. Less fertilizer or excessive fertilization: less fertilizer will cause orchids to be malnourished and wither; Excessive fertilization will cause the phenomenon of burning seedlings and destroying the ruler and withering leaves.

3. Excessive light: orchids are yin-loving and yang-phobing flowers.

4. The humidity is too low: orchids require humidity to be kept between 60% and 80%, and if it is too dry, there will be dead leaves.

5. Low temperature: Orchids are suitable for survival in a warm environment, and low temperature or freezing will cause orchids to wither.

6. Suffering from diseases or encountering pests: these will cause orchids to wither leaves.

7. Whether to change the pot and soil in time: Generally, orchids should be repotted and changed once in about 2 to 3 years.

8. Air pollution occurs in the environment of cultivating orchids: Orchids are one of the indicator flowers of air pollution, and they are very sensitive to air pollution, such as oil smoke, soot, soot, paint, air fresheners, chemical synthetic agents, pesticides, etc., which will lead to the withering of leaves and even death of orchids if they are not careful.
