What if the leaves of potted Phalaenopsis turn yellow? controlling the temperature to ensure light / watering is the key.

As a good indoor breeding product, Phalaenopsis flower shape butterfly, elegant color, let people see a stunning feeling, won the love of flower friends. However, in the breeding process, many flower friends will encounter very headache things, that is, yellow leaves, that potted Phalaenopsis leaves yellow how to do? In fact, it is very simple to find the cause and solve it. The specific method will be introduced in detail by Xiao Bian.

How do I find the yellow leaves of potted Phalaenopsis?

In the breeding methods and precautions of Phalaenopsis, we have already said that once the soil, light and moisture are not up to standard, it will cause the phenomenon of yellowing leaves. As for potted Phalaenopsis leaves yellow how to do, first we have to analyze the cause, and then for the solution can be. Here are the causes and solutions for yellowing potted Phalaenopsis leaves, and then look down.

2. Causes and solutions of yellowing of Phalaenopsis leaves

1. Too much watering

As mentioned earlier, moisture is crucial to the growth of Phalaenopsis, so once the consequences of improper watering are very serious. Too much watering, easy to cause Phalaenopsis rotten roots, resulting in yellow leaves; too little watering, leaves can not absorb water, the same will cause yellow leaves.

Solution: ① too much watering, put it in a ventilated place to dry, and change the pot and soil if necessary;② too little watering: increase the amount of watering, but don't overdo it, feel the soil wet with your hands.

2, the temperature is too low or too high

Phalaenopsis is native to tropical regions, so it has higher requirements for temperature, and its optimal growth temperature is 18-28℃. Phalaenopsis is not resistant to high temperature and cold, higher than 32℃ and lower than 15℃ will affect the growth of Phalaenopsis, resulting in yellow leaves.

Solution: In summer and winter should pay more attention to, when the temperature is higher than 32℃ and lower than 15℃, should be moved indoors, to ensure that it grows in a suitable environment, if necessary, open air conditioning.

3, the light is too strong

Too much light is also one of the reasons for the yellowing of Phalaenopsis leaves. Phalaenopsis prefer semi-shade and diffuse light. Strong light or long-term exposure to dark environments will affect photosynthesis of Phalaenopsis, making leaves yellow and soft.

Solution: At ordinary times, attention should be paid to avoiding strong light exposure while ensuring sufficient light. Do not direct in May-October, winter can be placed on a warm balcony.

4. Diseases and pests

When it comes to yellowing of Phalaenopsis leaves, many people will first think of insects, red spiders, scale insects and other pests will also cause yellowing and softening of Phalaenopsis leaves. Therefore, flower friends should ensure the circulation of air at ordinary times, clean up dead branches and rotten leaves in time, observe the surrounding environment of plants more, and ensure the cleanliness of growth.

Solution: When there are few pests in the early stage, you can use a soft brush to wipe the foliar insects clean, or spray pesticides. As for the more specific pest control of Phalaenopsis, there is an introduction in front, so I won't say more here.

2. Yellowing of Phalaenopsis leaves, on-site diagnosis

Although the above yellow Phalaenopsis leaves and solutions are very comprehensive, but for beginners, if you judge where the problem is the most difficult. The following are yellow leaf symptoms and cause analysis:

1. The top of new shoots of Phalaenopsis is atrophied, the young leaves are pale yellow, and the old leaves are gradually dark yellow.

Too much standing water: If this happens, your Phalaenopsis should have been standing water for too long, resulting in a lack of oxygen in the soil and some root rot.

Solution: water should be controlled and fertilization stopped.

2. The new leaves of Phalaenopsis grow plump and shiny, but the leaves are uneven, and the old leaves gradually yellow and fall off.

Excessive fertilization: encounter the above symptoms, do not hesitate, you must be too much fertilization. Everyone should pay attention to that the growing period of Phalaenopsis is not the faster the fertilizer is applied, there is a quantity problem.

Solution: should immediately stop fertilization, appropriate watering, sprinkle some radish or cabbage seeds into the pot, pull out after a few days of emergence, in order to consume excess fertilizer in the pot. Winter is not suitable for sowing, you can transplant a few small plants, and then remove another plant.

3. The top and new leaves of Phalaenopsis are normal, but the lower leaves of the plant dry and yellow first.

Insufficient moisture: encounter this situation, you usually watering must have problems, because at this time the yellow leaves of Phalaenopsis is not watered for a long time caused by dehydration of Phalaenopsis.

Solution: should be appropriate watering, keep the pot soil moist.

II. Cultivation methods and precautions of Phalaenopsis

1. Soil, slightly acidic

Different from other flowers, Phalaenopsis has high requirements for soil, generally choosing breathable, permeable, and rot-resistant slightly acidic soil. As the most important part of the breeding method and precautions of Phalaenopsis, Xiaobian recommends that you go directly to the flower market to buy orchid soil dedicated to Phalaenopsis.

Note: soil is done, basin is also to pay attention to. Flower friends should choose the right flower pot, do not use small pots for large plants, and do not use large pots for small plants, which will give Phalaenopsis a bad growth environment.

2, light, avoid direct light

Shade-loving is a characteristic of Phalaenopsis, but all green plants need plenty of light to produce the energy they need. Therefore, Phalaenopsis should also accept part of the light, especially before and after flowering, appropriate light can promote Phalaenopsis flowering, so that the flowers bloom beautiful and lasting.

Note: Phalaenopsis should generally be placed indoors with scattered light, do not let direct sunlight; if placed on the indoor windowsill, use window screens to block part of the sunlight, otherwise, after direct sunlight, the leaves are easy to yellow and dry.

3, moisture, see dry see wet

Phalaenopsis leaves are not easy to store water type, so it is necessary to have enough water in the soil, specific watering methods are as follows:

① Growth period: more watering;

② Dormancy period: less watering;

③ Spring and Autumn: watering once every day around 5 p.m. in two seasons. In summer, the plants grow vigorously, watering once every morning at 9 a.m. and 5 p.m.;

④ Winter: weak light, low temperature, watering once every other week is enough, should be carried out before 10 am;

Cold wave period: it is not suitable for watering, keep dry, and resume watering after the cold wave.

4, temperature, 15-30℃

In the cultivation method of Phalaenopsis, it also has high temperature requirements, generally 15-30℃, if it is lower than or higher than this temperature, there will be no growth or yellow leaves.

Note: Pay attention to maintaining temperature. Domestic Phalaenopsis is easy to grow because of low temperature, so in winter, flower friends must pay attention to keep Phalaenopsis warm.

5. Appropriate fertilization

How to raise Phalaenopsis, fertilization is also a very important part, because Phalaenopsis like fertilizer, appropriate fertilization, can promote the growth of plants. Otherwise, less fertilization will result in fewer flowers next year.

Note: do not feel that into the growth period will be hard fertilization, fertilization is generally good once 7-10 days. The fertilizer is applied once every 5-7 days in the growth peak season, once every 20-30 days in the growth slow season, and stopped when the temperature drops below 15 DEG C in winter.

6, ventilation is good

Ventilation is also a key link in the cultivation method of Phalaenopsis. Phalaenopsis also has very high requirements for air quality. Potted Phalaenopsis generally needs to be ventilated to prevent pests.

7. Proper pruning

How to raise Phalaenopsis, proper pruning is also very important. Phalaenopsis blooms, and flower friends need to cut off the withered flowers, shoulder the consumption of nutrients, and withered flowers hanging on top of it also looks very bad.

1. Shade

Summer is the vigorous growth period of Phalaenopsis, must be shade, in case of leaf burns. Generally shading 50%~60%; autumn sunshine is also strong, so until September still need shading 50%, October after the removal of shading materials.

2. Change the basin

Phalaenopsis flower should be promptly removed after pedicels and change pots. After taking off the basin, the original matrix will be removed, and rotten roots, dry roots cut off, replaced by new matrix can continue to maintain.

How to properly maintain the failure of potted Phalaenopsis

Phalaenopsis

Phalaenopsis flowers in full bloom shape and dancing butterflies are very similar, in the sunshine under the more dynamic, in many homes, offices, gardens and other places can be seen in it, in some areas can also be used as a bride's flowers. It can be seen that Phalaenopsis is so important in people's lives, but also often hear some flower friends reaction potted Phalaenopsis failure problem, is it difficult to cultivate Phalaenopsis success?

1. Reasons for failure of potted Phalaenopsis

1. Overwatering

Cultivate Phalaenopsis friends, always worry about Phalaenopsis water shortage, regardless of whether the cultivation medium is dry, watering every day, causing serious rotten roots.

2. temperature is too low

Phalaenopsis flowers are usually listed in early spring, and after buying home are generally placed in the living room and other places to enjoy, although the day temperature in these places is sufficient, but the night temperature is a little too low. Professional orchids, on the other hand, are mostly grown in well-equipped greenhouses, compared with homes where the temperature and humidity are slightly inadequate, making the plants tend to grow weaker and weaker. Therefore, no matter how well maintained orchids are, there are times when they do not bloom.

3. overfertilization

There is fertilizer on the application, and do not pay attention to the concentration, think that the application of fertilizer will grow fast. Phalaenopsis should be thin fertilizer, should be a small number of times. Remember that "tonic" can not be excessive, otherwise counterproductive.

4. Small plants grow in large pots

Think with big basin, can give butterfly orchid loose environment, use material sufficient. After its practical big basin, aquatic is not easy to dry, notice phalaenopsis likes aerate, gas general rule is comfortable.

Phalaenopsis

Second, how to raise Phalaenopsis

1. temperature

Phalaenopsis originated in tropical areas, like high temperature and high humidity environment, the minimum temperature during the growth period should be kept above 15℃, the growth temperature is 20~30%, more than 35℃ in summer or less than 10℃ in winter, its growth will be inhibited. The flowering period is full bloom around Spring Festival. Appropriate cooling can prolong the viewing time, but it should not be lower than 13℃.

2. moisture

Phalaenopsis is mostly grown on tree trunks in its original area, and its roots are exposed to the air, absorbing moisture from humid air, and the air humidity should be maintained at 70%. When cultivated artificially, the roots are buried in the culture medium, and if watered too much, the medium aeration will become poor, the fleshy roots will rot, the leaves will turn yellow, fall off, and in severe cases lead to death. The principle of watering: see dry see wet, watering is watered thoroughly. When the indoor air is dry, spray can be used to spray foliage, but note that flowering water mist can not be sprayed on flowers, so as not to drop flowers and buds.

3. illumination

Phalaenopsis need not much light, about 1/3~1/2 of the general orchid light, avoid direct light. If it is cultured on the windowsill indoors, it is necessary to use window screens to block part of the sunlight, 80% in summer, 60% in autumn and 40% in winter. Before and after the flowering period, proper light can promote the flowering of Phalaenopsis, making the flowers beautiful and lasting.

4. ventilation

Phalaenopsis needs fresh air, requires slow flow of air, avoid cold wind. During strong winds should be protected from light, suffered from wind damage to shelter. It's best when there's a breeze. To avoid wind damage, you can make a four-box, the box is made of thin wood, and the frame height is 30~40 cm. Spread a layer of wet sand inside the frame, which can prevent wind and increase humidity, killing two birds with one stone.

5. nutrition

Phalaenopsis cultivation generally selected aquatic plants, moss for cultivation substrate. The principle of fertilization should be less fertilizer, light fertilizer. Apply 2000 times solution of orchid special fertilizer in normal growth period, apply fertilizer to roots, and apply once every 2~3 weeks according to growth conditions. Before flowering, 1000~2000 times solution of compound flower fertilizer with water-soluble high phosphorus and potassium fertilizer can be selected, and sprayed once every 10 days. Fertilization should be stopped during flowering and cooler seasons.

6. pot change

It takes about two years from seedling to flowering. Adult Phalaenopsis should change pots and plant materials after flowering every spring, otherwise it is easy to accumulate dirt and moss, plant materials are also easy to decay, breeding diseases and insect pests. Potted Phalaenopsis, suitable for porous vegetable pot. When planting, the plant material placed in the bottom of the pot should account for at least 1/2 of the pot capacity, and part of the roots should be exposed to the pot surface. Do not bury them deeply, otherwise it will hinder breathing and growth.

Phalaenopsis to change the pot seems to be a very simple matter, but if the operation time is not appropriate is also very easy to help Oh! Xiao Bian suggested that the pot change for Phalaenopsis should be carried out during its dormant period and early growth, and it is best to change pots in spring and autumn, which has little effect on Phalaenopsis.
