What is the situation of potted phalaenopsis orchids that rot leaves and roots in summer?

Phalaenopsis must be very familiar to many flower friends, the name is good, and the flowers are still many and bright, but there is one thing to pay attention to, that is, usually good-looking flowers, are more difficult to "serve", especially in the summer, this is a difficult period for raising flowers, a little careless, a week will only be left pots!

Phalaenopsis is no exception, and rotten roots, wilting leaves, etc., often occur in summer, so today's Huahua tells you how to raise phalaenopsis!

However, when maintaining, it should be noted that the phalaenopsis orchid that has just been bought, after the flower withers, must be pruned frequently, so as to reduce the degree of nutrients consumed by the flower, and also retain a lot of nutrients to prepare for the next flowering.

Although Phalaenopsis prefers sunlight, the light in summer is too strong, and it is easy to wilt it, especially in the midday sun, so it is best to put it in the living room, so that the light and temperature can meet the requirements!

The growth temperature of phalaenopsis is generally about 25 degrees, once the temperature is higher than about 32 degrees or lower than about 15 degrees, phalaenopsis will enter a dormant state and grow slowly. Therefore, if you want Phalaenopsis to grow faster, you can control the temperature of the environment, so that Phalaenopsis can grow very lushly.

After the phalaenopsis blooms for about half a month, it is necessary to start using phosphorus and potassium fertilizers, which must have certain nutrients, so as to promote the flowering time. When fertilizing, apply more, and the time of light must be appropriate, so as to promote the flowering time of the flowers, and also make the phalaenopsis grow more lushly.

When watering phalaenopsis again, you must make sure that the potting soil is relatively dry before watering. Generally, touch the surface of the soil with your hands, and replenish water in time when it is relatively dry, and when watering, you must water until the drainage hole appears, and it can not cause water accumulation.

The Phalaenopsis maintained at home must have good ventilation, otherwise it will lead to poor plant growth, and may also lead to direct rot of the roots of the plant, or there will be frequent diseases, which is very unfavorable to the flowering of Phalaenopsis. The most important thing is to put the phalaenopsis in a very transparent environment.

The maintenance methods introduced above will be very much more when you learn to bloom, and they are also very colorful.

First of all, the light intensity is not suitable. The water retention structure of the cuticle on the leaf surface of Phalaenopsis is relatively poor, and if it is exposed to direct sunlight, it will lose water quickly, resulting in sunburn spots, resulting in leaf decay. Therefore, the cultivation of phalaenopsis should not ignore the need for moderate shading, even in winter and spring, it can only be exposed to direct sunlight in the morning and evening.

Secondly, it is caused by improper watering and fertilization. Watering phalaenopsis varies depending on the medium, temperature and season, but the general rule is to keep the medium moist and not dripping.

Because Phalaenopsis is an aerial orchid, it is generally cultivated without soil, and is often planted with moss, pine bark, coconut shell powder, ceramsite and other substrates, so when watering Phalaenopsis orchid, it is necessary to consider the moisture content of its substrate, not too dry or too wet, otherwise it will also cause the leaves to wither yellow and rot.

It may be that the plant lacks nutrients, and nitrogen and potassium fertilizers should be supplemented in time to promote the growth of plant rhizomes. It is also possible that there are pests and diseases on the leaves of the plant, and plant-specific insect repellent should be used.

If the foliar fertilizer is sprayed too much and too much, coupled with the lack of attention to ventilation, or the fertilizer is drenched on the leaves, the leaves will rot due to fertilizer injury.

Domesticated phalaenopsis, in case of dry weather and insufficient humidity, can be sprayed regularly 2 3 times a day; In winter, when the temperature drops below 15, you don't need to water, just spray once a day in the afternoon when the temperature gets high.

When watering or sprinkling, if water is retained on the leaf surface, it should be immediately used on a cloth or dry paper to dry or blot to prevent the occurrence of stem and leaf rot; In summer and autumn, rain should be protected to avoid causing rot.

When watering, do not splash the leaves with water, because it is easy to cause leaf rot after splashing, especially in winter. During the spring-summer growth period, it should be watered 1 time a day and sprayed 2 3 times; In autumn and winter, as the temperature decreases, the amount of watering should be gradually reduced, watering once every 2 5 days, and stop spraying, and keep the potting soil slightly wet.

Fertilization method:

Because organic fertilizer will produce peculiar smell after application, which affects the hygiene of the room, the fertilization is generally based on chemical fertilizer.

Commonly used chemical fertilizers include potassium dihydrogen phosphate, diammonium phosphate and orchid special fertilizer, application concentration, 1 time in 5 7 days in the peak growth season; 1 time in 20 30 days in the slow growing season; Stop fertilizing in winter when the temperature drops below 15.

In the cultivation process, the types and proportions of fertilization are also different during different growth periods. The ratio of nitrogen, phosphorus and potassium fertilizer was 1:1:1 in the vegetative growth stage of small and medium-sized seedlings. Large seedlings and flowering plants are 1::4.

1. Watering phalaenopsis should be done when it is dry and wet, and it is not dry and watering, but it is the principle of watering thoroughly.

2. The second is to strengthen the ventilation and permeability of the roots, use, the flower pot with holes is the flower pot, in addition to the bottom of the hole, there should also be holes on the side, so that the ventilation is not easy to rot the roots.

3. Phalaenopsis should be placed in a ventilated place. This is also not easy to lead to root rot.

Phalaenopsis planting tips.

1. Planting time.

Phalaenopsis planting is done at the right time, usually in spring or autumn. Spring is between February and May, and autumn is between August and October. The climate temperature during these two periods is suitable, the temperature is not high or low, the seeds can germinate better, and it is more convenient to manage them at ordinary times.

2. Select the seeds.

To plant phalaenopsis, you need to choose suitable seeds, and empty packets are not available, so even if they are planted, they will not grow small seedlings. To choose a full particle, it is best to have a uniform size. The seeds should be disinfected before entering the soil, and they can be soaked directly in carbendazim solution, and then dried before sowing.

1. Phalaenopsis must be planted with special soil for phalaenopsis, which are rotten wood or moss. It has good water permeability and air permeability, and is not easy to rot roots.

2. Find out in time whether Phalaenopsis is attacked by pests and diseases. If rot is found in the roots, it should be treated immediately with medication.

3. Phalaenopsis should be placed in a ventilated place. This is also not easy to lead to root rot.

Phalaenopsis planting tips.

1. Prepare the matrix.

The substrate used to grow phalaenopsis must be soft, breathable, permeable, acidic, alkaline and unusable. It is recommended to mix peanut shells, pine needles, bark silk, etc. evenly as a substrate when formulating. Note that it needs to be disinfected after preparation to prevent insect eggs or germs.

2. Sow seeds into the soil.

Phalaenopsis seeds are well treated, and the substrate is prepared before sowing. Place the seeds evenly on top of the soil, cover them with a thin layer of soil, and water them appropriately to make the substrate slightly wet. In the later stage, it is maintained in a warm and ventilated place, and if the environment is suitable, the seedlings will emerge soon.

How do phalaenopsis "water"? He watered it once a week, it won't rot the roots, it's simple and practical!

There are many reasons for the rotten leaves of Phalaenopsis orchid, and it is necessary to find out the specific reasons before saving, and only in this way can targeted rescue be carried out. Most often, rotten leaves are due to soft rot, which will appear spotted at the beginning of the disease and later turn brown and begin to increase the extent of the rot. Rotten leaves should be cut off in time, and carbendazim or methyl tobuzin, Bordeaux solution should be sprayed for control.

If leaf rot is severe, it is necessary to isolate the diseased plant from other plants, and ensure that the maintenance environment is well ventilated and the humidity is not too high.

The usual maintenance method is unreasonable, which will cause rotten leaves of the plant, so after cutting off the diseased leaves, it is necessary to completely change the maintenance method. First of all, the temperature should not be too low when farming, and do not splash water on its leaves when watering. It is not feasible to go without sunlight for a long time, but you should not see bright light suddenly, so you should gradually increase the light.

If you want Phalaenopsis to water without rotting roots, you need to wait for the soil surface to dry before watering, and keep the soil slightly moist. Zhengmingfu

Phalaenopsis likes to be waterlogged, but it is not resistant to waterlogging, if you want Phalaenopsis to water without rotting roots, you must control the frequency of watering, it is best to wait for the soil surface to dry out before watering, you can use a cotton swab to insert it into the soil, if the cotton swab is wet after being extracted, it means that the soil contains water, and it is not appropriate to water Phalaenopsis at this time.

When cultivating phalaenopsis, it is necessary to move the plant to a ventilated environment after watering, so that the soil moisture can be quickly evaporated, so as to avoid the root system of phalaenopsis from rotting due to too humid environment, and when watering phalaenopsis, the water can not be sprinkled on the flowers and leaves of the plant.

Phalaenopsis orchids are not resistant to strong light, and when cultivating phalaenopsis, it is necessary to place the plants in an environment with sufficient scattered light, so that they can receive a suitable environment to avoid being burned, but in winter, phalaenopsis can be moved to a sunny place to allow it to receive all-weather natural light.

The allegory and symbol of Phalaenopsis orchid

1. Business is booming

The flower language of yellow phalaenopsis is a prosperous business and prosperous business, its appearance is very atmospheric, like a flower butterfly, suitable for placing in the store, symbolizing the rolling of wealth, the continuous flow of customers, and the phalaenopsis can also play a decorative effect.

2. Everything goes well

I hope that everyone dares to think and dare to do in life, without too many worries, to be a happy and open-minded person, you can give the Phalaenopsis to friends who are not in a good mood.

3. I love you

The main meaning of Phalaenopsis is that I love you, it is often used to express love, it is very suitable for giving it to the person you like, it can be used as a confession flower, and the Phalaenopsis orchid is given to the wife who has been in love for many years, which can deepen the feelings of each other.

Phalaenopsis rotten leaf solution:

The cause of the leaf rot of the potted phalaenopsis orchid is most likely the yellowing of the leaf rot caused by the soft rot of the phalaenopsis. Here's how to fix it:

1. The suitable temperature for the growth of germs is 28 30 degrees Celsius, so controlling the amount of watering, improving ventilation conditions, and reducing the temperature and relative humidity in the greenhouse are the keys to prevent the occurrence of soft rot. In addition, in the high incidence period of soft rot, spray 80 mancozeb wettable powder 500 times a month regularly once a month to prevent the occurrence of soft rot.

2. Completely remove diseased plants and leaves, and cut off diseased parts or tissues in time. Generally, it is cut from the junction of 5 10 cm at the edge of the lesion, because although there are no obvious symptoms here, it belongs to the poisoning layer and has latent germs in it. Knives that have been cut from diseased strains should be sterilized to avoid re-infection with other orchid strains.

After the diseased part is cut off, it is smeared with a high-concentration agent at the incision, that is, 500 ml of 100 times of 80 mancozeb wettable powder plus 2 million units of streptomycin plus a little soap powder are mixed and smeared, or Bordeaux liquid, or smeared with other fungicides, and no watering for 1 week after application, so as to block the further expansion and spread of the disease in time.

3. Drugs**. During the onset of the disease, spray 1000 times of 72 agricultural streptomycin, 2000 times of tetracycline, or 1500 times of 77 killable wettable powder once a week.

Soft rot is one of the common diseases of potted phalaenopsis. The pathogen of soft rot can infect phalaenopsis leaves, peduncles and petals at all stages of growth. After infection, the leaves appear water-stained spots, translucent to the glossy surface, and then gradually turn brown and expand rapidly.

The symptoms are like hot water scalding, the diseased leaf tissue is filled with water, and it will rupture when pressed lightly by hand, and secretions will flow out, and a foul odor will occur in the later stage. The disease spreads rapidly under the conditions of high temperature and high humidity, and is highly contagious, and can cause the whole leaf to rot within 3 to 5 days; When the base of the leaf or heart leaf is infected, the entire orchid plant dies and quickly spreads to the surrounding orchid plant.

Once the disease occurs, it must be prevented as soon as possible to prevent its spread. Soft rot mostly occurs in the summer high temperature and humidity season, especially in the rainy season at the beginning of summer. This disease is more likely to occur when there is high temperature and humidity, poor ventilation, and excessive application of nitrogen fertilizer.

The route of infection is through wounds, such as bumping, insect bites, or improper handling when cutting off diseased leaves.

It depends on what the situation is:

Situation 1: frostbite on leaves, little impact, pay attention to normal temperature maintenance, suitable for the growth of Phalaenopsis temperature: 15 to 30 degrees, generally maintained at more than 20 degrees better, below 15 degrees easy to freeze or even die seedlings.

Situation 2: Soft rot, cut off the lesion with sterilized scissors, disinfect the wound with alcohol, and maintain it normally. If the rotten part is more serious and the cut is not clean, carbendazim can be applied to the lesion.

The key to raising Phalaenopsis is to pay attention to the following points:

1.Temperature: 15 to 30 degrees, below 15 degrees will freeze to death, above 33 degrees it is easy to enter a semi-dormant state, affecting growth.

2.Light: Phalaenopsis likes light but is afraid of direct sunlight, usually placed in a place with scattered light, and needs to be shaded if the light is too strong in summer.

3.Ventilation: Phalaenopsis prefers a well-ventilated environment and needs to open windows frequently for ventilation, but in northern areas, it is necessary to avoid cold winds blowing to Phalaenopsis in winter.

4.Watering: Phalaenopsis "likes dryness and is afraid of dryness, likes moisture and is afraid of waterlogging", watering should follow the principle of dry and thorough watering, and must not be watered every day, otherwise it will rot roots and dead seedlings.
