What should I do if the Phalaenopsis has lost its leaves and withered not long after I bought it?

After the flower wilts, the flower stem can be cut off from the base, and when the substrate is aged, it should be replaced in time. Apply a callus antiseptic film to the cut to prevent nutrient loss.

Raising flowers is nothing more than a few elements: soil, watering, sunlight, ventilation. It depends on what kind of flower you have, what kind of environment and management it is suitable for.

When it comes to phalaenopsis specifically, it may be a highly permeable and breathable soil, more conservative watering management (don't always be uncontrollable to water yourself, phalaenopsis is watered about once every 3-7 days depending on different soils), a shady and cool light environment but also occasional morning sunshine, and finally a ventilated environment. According to the above ordinary orchids, phalaenopsis should be about the same.

Pruning, cut off all the leaves of phalaenopsis pests and diseases, and cut off half of the complete leaves to reduce nutrient loss.

Change the culture medium, we know that phalaenopsis needs substrate for growth, generally we use wood chips and moss, here I use wood chips.

When the room temperature is as high as 28 or more, try to open the window for ventilation, and if necessary, start the fan to exhaust the air; During the winter flowering season, ventilation should be done once a day or every other day to ensure the smooth growth of flowering plants.

Water every 3 days in spring and autumn, every 2 days in summer, and 4 to 5 days in winter. In addition, seedlings should be watered with less water and flowering plants should be watered with more water. Watering should be done in the summer after the sun goes down, and in other seasons in the morning and before the temperature rises.

Pay attention to watering in time, watering the aquatic plants when they are dry, watering the aquatic plants if they are not dry, and pay attention to heat preservation in winter if they are afraid of waterlogging, fear of cold, and fear of freezing.

Phalaenopsis prefers warm, humid and semi-shady environments. The optimal growth temperature is 25 to 28 during the day and 18 to 20 at night. When the temperature is above 35 in summer or below 10 in winter, phalaenopsis stops growing.

Cut off all the phalaenopsis taproot and fibrous roots, to what extent? Cut until there are no black spots at the root of the phalaenopsis.

In general, the amount of light that Phalaenopsis orchids receive is limited by how well their leaves are not burned, and the stronger the light, the better it grows.

Phalaenopsis flowering is usually caused by three reasons. One is that the temperature is too low, low temperature will frostbite the plant, and the flower buds are easy to fall. The temperature should be controlled as soon as possible, and the temperature should be between 17-24 degrees.

First, the temperature is too low.

Reason: Phalaenopsis should control the temperature after it grows buds, and it is afraid of low temperature environment. If the temperature provided at this time is too low, the plants will easily get frostbitten and the flower bones will easily fall.

Treatment method: If the frostbite is low temperature, the temperature must be controlled, and the temperature should be maintained between 17 degrees and 24 degrees, and the minimum should be above 10 degrees. In addition, care should be taken not to get too close to the heating equipment to avoid being burned.

2. Improper fertilization.

Reason: Phalaenopsis consumes more nutrients during flowering, and should be nourished before flowering. If the plant is undernourished, it is easy to fall even if it grows buds. In addition, when fertilizing, pay attention not to apply thick fertilizer, otherwise it is easy to bring fertilizer damage and cause flower bones to fall.

Treatment: To timely fertilizer treatment, more time containing phosphorus and potassium elements of fertilizer, pay attention to control the concentration, it is best to dilute with water first, and then apply fertilizer, which can promote vigorous growth and better flowering.

3. Overwatering.

Reason: It needs to be properly treated with water control after it has grown buds. At this time, the water demand will be greatly reduced, and the water should not be given as before, otherwise it will easily lead to bud fall.

Treatment method: stop water treatment first, and move the plants to a well-ventilated environment to evaporate the water in the flower soil, and pay attention to reducing the amount of water in the later stage.

Phalaenopsis flowering is usually caused by three reasons. One is that the temperature is too low, low temperature will frostbite the plant, and the flower buds are easy to fall. The temperature should be controlled as soon as possible, and the temperature should be between 17-24 degrees.

Second, improper fertilization, lack of nutrients or high concentration of fertilizer applied are easy to drop flower buds. If there is a shortage of fertilizer, it should be treated with fertilizer, pay attention to reducing nitrogen fertilizer, and dilute it before applying. The third is excessive watering, after the flower buds grow, the water should be controlled, and moved to a ventilated place to evaporate excess water.

The causes of phalaenopsis bud fall include excessive temperature difference between day and night, root damage, environmental pollution, insufficient photosynthesis, poor ventilation in the greenhouse, high temperature between day and night, excessive humidity of the medium, too low relative humidity of the air, mechanical damage, use of hormonal drugs, and insect pests such as mites.

The temperature difference between day and night is too large

The temperature difference between day and night is too large, and the plant cannot adapt to the sudden change in temperature conditions, which will cause bud drop.

mites and other insect pests

Generally, the flower buds will suddenly become dehydrated, and the color will also change to an abnormal dark red, and when the insect infestation is serious, all the flower buds will fall.

Damaged root system

Improper application of water and fertilizer will cause abnormal growth of the root system, and if the root system remains in a state of hypoxia for a long time, it will be difficult to provide sufficient nutrients, resulting in bud loss.

Environmental pollution

When the air is polluted, the harmful substances contained in it enter the tissues of the buds due to the effect of osmotic pressure. At this time, the damaged bud is opened, and small water droplets can be seen inside; Most of the contaminated buds are yellowish-brown, and in severe cases, they are black, and they will become moldy and fall off.

Insufficient photosynthesis

If there is not enough light during the day, respiration will increase at night, which will make the nutrients inside the plant in short supply, making it difficult to maintain normal bud growth.

Poor ventilation in the greenhouse

If the indoor air is not ventilated in a timely and adequate manner, it is difficult to provide sufficient fresh carbon dioxide for Phalaenopsis for photosynthesis, and the nutrient production will also be insufficient.

Temperatures are on the high side both day and night

That is, the temperature during the day is higher than 29, and the temperature at night is higher than 20, which will accelerate the metabolism of the plant, resulting in excessive loss of nutrients, and it is easy to make the flower buds yellow, and serious ones will fall.

The medium is too wet

If the medium is too wet during the flowering period, it will greatly reduce the oxygen content inside the root system, which will adversely affect the normal development of flower buds.

The relative humidity of the air is too low

The humidity of the air does not meet the conditions required for the normal growth of phalaenopsis, which will cause the pollen grains in the flowers to fall off.

Mechanical damage

When pruning phalaenopsis orchids, if the inside of the peduncle is accidentally traumatized, it will affect the normal nutrient level**. or if the root system is accidentally broken during potting, the normal nutrient supply of the plant will also be affected.

Use of hormonal drugs

If hormones such as flower buds and mequat are sprayed during the flowering and seedling raising periods of phalaenopsis, it is also easy to cause the plant to fall off buds.

Don't worry, Phalaenopsis "drops buds", know the "4 points" reason, it's easy to deal with!

Phalaenopsis may be that the soil is not suitable for the growth of the plant, and the plant needs to be replaced with suitable soil for replanting, or it may be that the light provided for the plant in the process of maintaining the phalaenopsis is too strong, resulting in the plant being burned by strong light, and the light should be reduced.

1. Replace the soil

If the phalaenopsis is withered, it may be that the soil provided for the plant during the planting of the phalaenopsis is not suitable for the growth of the plant, and the plant needs to be replanted with different soil. Phalaenopsis is suitable for growing in soil with rich nutrient content and good drainage, so it is best to use sandy loam soil rich in trace elements when planting phalaenopsis.

2. Reduce light

Phalaenopsis withering may also be due to the excessive light provided to the plant in the process of maintaining Phalaenopsis orchid, resulting in burns and dry leaves of the plant, so it is also necessary to provide suitable light for the plant when maintaining the phalaenopsis, generally in the morning to provide sufficient light for the plant, in the afternoon it is necessary to provide proper shade for the plant.

3. Increase moisture

Phalaenopsis withering may also be due to the lack of water provided for the plant during the maintenance of Phalaenopsis orchid, resulting in the lack of water and drying up of the plant, so it is necessary to provide the right amount of water for the plant when maintaining the phalaenopsis orchid, it is best to provide water for the plant when the soil is relatively dry, keep the soil moist, or spray water on the plant to keep the environment moist.

4. Reduce nutrients

Phalaenopsis withered may also be in the maintenance of the plant to provide too much nutrients for the plant, resulting in fertilizer damage to the plant, so in the maintenance of Phalaenopsis orchid needs to provide nutrients for the plant reasonably, it is best to dilute the fertilizer to provide the plant, so that the plant can absorb more nutrients and grow more vigorously.

If the Phalaenopsis flowers are gone, and the leaves have fallen off and are still alive, you can take the following steps to take care of them:

Pruning of dead leaves: Cut off leaves and wilted branches to keep the healthy parts.

Soil replacement: Clean up the old soil and replace it with a new nutrient-rich and breathable soil, such as humus soil or peat soil.

Fertilization: Phalaenopsis can be watered for the first time of each month with an appropriate amount of special fertilizer to supplement the nutrients needed by the plants.

Waiting for recovery: After the above care, you need to wait patiently for the phalaenopsis to resume growth, and it generally takes a few months to half a year to transport the slag.

It should be noted that Phalaenopsis is a relatively delicate flower species, and it can be maintained indoors if conditions permit, so as to provide a more stable growth environment with the cover removed.

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.

The reasons for phalaenopsis leaf loss are: improper light and uncomfortable temperature.

1. Improper lighting

Light affects the health of the growth of plant plants, Phalaenopsis likes to grow in a semi-shady environment, especially in the summer high temperature, Changfan Bowei is exposed to the sun, which will lead to leaf fall. In addition, although it likes shade, if it is too shady, it will also cause the leaves to fall.

Solution: In spring and autumn, there should be moderate light, which can be placed in the place of scattered light indoors. In summer, it is necessary to shade the sun to prevent it from being exposed to the sun. In winter, it can be fully illuminated and the conditions of the sedan car can be fully carried out.

2. Uncomfortable temperature

Phalaenopsis flowers are best suited to grow at temperatures between 18 and 28 degrees, and when the growth temperature is relatively high, it is not conducive to plant growth, resulting in leaf drops. If the temperature is relatively low, it will also cause the leaves to fall.

Solution: When we grow phalaenopsis, it is best to maintain the right temperature. When the summer temperature is 32 degrees Celsius, it will be dormant, so it is necessary to take appropriate cooling measures. In winter, it should not be lower than 15 degrees Celsius, and it can be placed indoors in a warm and sunny place.

Daily maintenance

When the plant blooms, sometimes there will be a phenomenon of drooping at the top of the flower stalk, which can be supported by bamboo poles, and the potted phalaenopsis can be supported by iron wire, and the upper part is specially bent so that the flower branches have a certain shape, thus improving the ornamentality.

After all flowering is completed, the flower stalks drawn from the base of the plant should be cut off in time to prevent nutrient consumption. If you want the plant to bloom again next year, you can combine repotting to shorten the flower stem.
