Lagerstroemia indica bud does not open.

Why can't my flowers bloom? Finally, thank you for returning the bud? It's so depressing Today, Huahua will give you a detailed analysis of the causes of bud loss and solutions!

1. Causes of camellia bud drop 1: moving position

When camellia is about to bloom, people will put it in a place where it is easy to watch. However, the light intensity and time in the new place are different from the original, which will disrupt the growth rhythm of camellia and lead to the phenomenon of bud drop of camellia plants.

Solution:

Try not to move the camellia when it blooms. Even if you want to move your position, you can't be too different from the previous environment!

Reason 2: improper watering.

Camellia should avoid water accumulation. If the pot soil is too wet, the roots can't suck normally, which will lead to falling flowers and buds. During the flowering of camellia, the soil in the basin should be kept moist and dry. Too dry will lead to dehydration and death of fleshy fibrous roots; If it is too wet, the fibrous roots will suffocate and rot due to accumulated water. When plants can't get water supply, they will drop their buds first and then their leaves.

Solution:

If the basin soil has been completely dried, a small amount of water should be poured first to make the basin soil gradually moist, and then watering, otherwise the root tip will lose water and the sudden flood will not adapt, which will easily lead to falling buds. Water it until it is about 70% dry in winter, and water it with warm water at noon on sunny days.

Reason 3: pH discomfort.

Camellia likes acid, and sandy soil with pH value of 5-6.5 is more suitable. Overacid or overbased soil, sticky soil, saline-alkali soil and calcareous soil will make camellia grow poorly and some trace elements cannot be absorbed. Lack of phosphorus, iron, sulfur and other nutrients in the soil will also form the phenomenon of green deficiency and bud loss.

Solution:

Should be symptomatic weekly spraying 0.2% ferrous sulfate solution.

Reason four: the temperature is uncomfortable.

Pay attention to adjusting the temperature. When the temperature drops to near 0℃, move the camellia to the indoor light and cover the curtain to keep warm at night. 3 ~ 5℃ is suitable for overwintering. If it exceeds 16℃, it will germinate ahead of time, causing deciduous leaves to fall off. Below 0℃, the buds will be frozen.

Solution:

The temperature before flowering shall not be lower than 5℃ to 7℃, and the flowering temperature shall be 10℃ to 15℃, and the maximum temperature shall not exceed 20℃. Camellia can keep flower buds when the temperature is above 2℃ in winter. Camellia is most afraid of too large a temperature difference. Sometimes high and sometimes low, the buds will all fall off.

Reason 5: Poor ventilation.

In winter, camellia leaves will fall off if it is kept indoors for a long time, with poor ventilation, dirty air or room temperature exceeding 20℃.

Solution:

If the family environment is sultry, you can properly open the window at warm noon to breathe, which will help the growth of camellia.

Reason 6: Too many buds.

Too many camellia buds will inevitably disperse nutrition, causing the buds to fall off due to insufficient nutrition.

Solution:

When the bud is about the size of soybean in August, the branches should be thinned in time, and only one well-developed bud should be left on one branch, especially on plants with weak growth.

Reason 7: Improper fertilization.

Apply thin fertilizer frequently, avoid applying raw fertilizer and thick fertilizer.

Solution:

From early spring to before flowering, nitrogen and phosphorus mixed liquid fertilizer 1 ~ 2 times can be applied to prevent bud falling, but nitrogen fertilizer should not be too much. In autumn, we should store enough nutrients for flowering. When flowering, flowers can be colorful.

From September to 10, apply dilute high phosphate fertilizer every month, such as chicken manure and strong buds. June 1 1 Stop fertilizing, never in winter.

Fertilize when sleeping, even if you apply thin fertilizer, it is easy to drop buds.

2. The reason for the bud drop of Crab Claw Orchid 1. Cold current invasion.

In the northern region, when the rootstock stops growing in winter, most of the buds of the whole plant will fall off, especially the crab claw orchid with the rootstock of Trigonella tricuspidata.

Solution:

Pay attention to cold protection after the end of autumn. It is best to move indoors in advance and cultivate in a sunny place.

Reason 2: sudden cooling or large temperature difference between day and night.

Crab claw orchid is warm. If the temperature suddenly drops below 10, the phenomenon of falling buds will appear.

Solution:

When the temperature drops suddenly, keep warm indoors in time. You can put a plastic bag on the crab claw orchid to keep warm. Remember to punch more holes for air. Avoid suddenly moving from a low-temperature balcony to a high-temperature room with heating.

Reason three: improper watering.

Too much watering is easy to accumulate water, which is more likely to lead to crab claw rot! However, if the water is too little, the crab claw orchid will not absorb enough water, and it is very easy to cause the bud to fall when it is ready to be released.

Solution:

After the crab claw orchid sprouts, it must wait until the soil is dry before watering, and continuous watering is not allowed, otherwise it will easily cause bud drop. However, watering should not be too little, and the pot soil is too dry and it is easy to cause buds to fall off.

Reason 4: Insufficient fertilization.

Crab claw orchid failed to fertilize in time before and after budding, and its nutrition was insufficient, which also easily caused bud drop.

Solution:

Applying thin fertilizer frequently and applying more phosphorus and potassium fertilizer can promote flowering.

5. Move the flowerpot at will

Disposing flowerpots at will during flowering period will lead to broken stems, which will easily lead to falling flowers and buds.

Solution:

Put the plants in a sunny place, and always let the plants receive light evenly in a special flowerpot. Don't touch the flowerpot casually, and keep your hands under control!

Six, watering too much

If the buds are watered too much in the early stage, they will fall off easily.

Solution:

Keep the pot soil moist, and spray water on the plants often during bud stage, but no water can accumulate ~

3. The reason of Rieger Begonia falling buds: The air is too dry.

The air is too dry, so Rieger Begonia can't absorb enough water from the air, and it will begin to shed buds gradually.

Solution:

Spray water with the same temperature as room temperature around Rieger Begonia to increase the ambient air humidity, or use an air humidifier to increase the indoor humidity.

Reason 2: Poor ventilation.

If Rieger Begonia is kept indoors for a long time, the air will be dirty, which will also cause the buds of Rieger Begonia to fall off.

Solution:

Open the window every day for ventilation 1~2 hours.

Reason 3: The temperature is too low.

The buds of Rieger Begonia are not cold-tolerant, and once they are frozen, they fall off easily.

Solution:

Put Rieger Begonia indoors, don't let Rieger Begonia suddenly freeze, and give Rieger Begonia a stable and warm environment.

Reason four: too much water.

If you water too much, water will accumulate in the flowerpot. In the long run, Rieger Begonia is easy to rot, and once the roots rot, it is inevitable to drop buds.

Solution:

Wait until the soil surface is dry before watering. Water it thoroughly!

4. The first reason why Phalaenopsis shoots off: the large temperature difference between day and night leads to neglect.

Due to sudden changes in the environment, such as condensed water and cold air, plants can't adapt to the environment, which leads to flower buds falling off.

Solution:

Try to avoid Phalaenopsis changing places, try to put Phalaenopsis indoors to reduce the temperature difference between day and night.

Reason 2: Insect pests

For example, mites, the buds that are about to open suddenly dehydrate and the color is dark red. When the situation is serious, all the buds fall off! When this happens, friends can carefully observe whether there are tiny ivory or brown bugs in the bud.

Solution:

Kill with special pesticides!

Reason three: root damage.

Because of improper production such as watering and fertilization, the root system is not full. It is also possible that the root system is in a state of hypoxia for a long time and the nutrient supply is insufficient, which leads to short flowering period or budding.

Solution:

Loosen the soil for the flowerpot and let the roots breathe fresh air!

Reason 4: The greenhouse is poorly ventilated.

The polluted air affects the respiratory function of Phalaenopsis, which will cause the bud to fall off in severe cases.

Solution:

It is necessary to exchange indoor air with outdoor fresh air to provide enough fresh carbon dioxide for Phalaenopsis. In a certain space, the more carbon dioxide, the longer the flowers bloom.

Reason 5: The temperature is high day and night.

The temperature is above 29℃ during the day and above 20℃ at night, which is the so-called "forced rush". High temperature day and night will accelerate the metabolism of plants. If the light is insufficient, the flower buds will turn yellow easily, the flowering period will be greatly shortened, the petals will be dim and the flowers will become smaller. Solution:

Appropriately reduce the indoor temperature and increase the light.

Reason 6: The soil is too wet.

In the flowering period of Phalaenopsis, dry medium is beneficial to the gorgeous flowers, but too dry medium will lead to deep flowers and small flowers (low air humidity will also lead to small flowers); Too wet medium and low oxygen content in roots will seriously affect the development of flower buds, and flowers will be small and dull or fall off.

Solution:

Keep the soil slightly wet when watering, pay attention to watering thoroughly, and don't accumulate water!

Reason 7: The relative humidity of air is too small.

This will easily cause the buds to wilt and fall off, which will have a great influence on the size and color of flowers. If the relative humidity is low to a certain extent, the friends of the flowers will naturally fall off and the flowers will wither.

Solution:

Sprinkle water around Phalaenopsis or use an air humidifier to increase humidity.

5. reason 1: insufficient light.

Jasmine is a positive photophobe, and its growth and development need sufficient light. The planting place or the place where potted flowers are placed is too shaded and the illumination time is too short, which will inevitably cause the branches and leaves to grow white and affect the formation and differentiation of flower buds.

Solution:

Put the jasmine in a sunny place!

Reason 2: Matrix discomfort.

Jasmine likes slightly acidic soil and should be planted on yellow soil with rich humus and pH value of 6.0-6.5. If the soil planted or the prepared substrate is alkaline, the growth and development of plants will be affected, buds will begin to fall off and flowers will not bloom.

Solution:

Pour some vinegar or spray jasmine with ferrous sulfate ~

Reason 3: Watering is unscientific.

This is the main reason why jasmine buds fall off and wither prematurely. Too much watering and too wet soil will lead to long-term water saturation, insufficient oxygen supply and poor breathing, which will lead to root rot or mildew. Too little watering, too dry soil and long-term water shortage of plants will cause flowers and trees to wither due to water imbalance.

Solution:

Water must be done without watering and thoroughly. If you have confidence in yourself and can keep the soil moist, that is the best.

Reason 4: The temperature is too low.

The environmental temperature of jasmine flower growth is too low to reach the minimum temperature required for flower bud differentiation and bud development, and jasmine flower will naturally fall off.

Solution:

Put the jasmine indoors, or raise the temperature around the jasmine, or cover it with a transparent bag and poke a few holes to breathe.

Reason 5: Too little pruning.

If jasmine flowers are not pruned for a long time, it will affect their ventilation and light transmission, and there will be too many buds and serious nutrient diversion, which will also cause bud loss.

Solution:

Loosen the flower buds of jasmine and control the number of flower buds. Prune twigs and concentrate the nutrients of jasmine.

6. Causes of gardenia bud drop 1: lack of fertilizer

Gardenia is lack of fertilizer, and the growth potential of the tree is weak. Even if it bears buds, it is easy to dry up and fall off.

Solution:

Pay attention to applying some nitrogen fertilizer and iron fertilizer during maintenance, increase the supply of phosphorus and potassium fertilizer after budding, and increase the supply of base fertilizer when turning over the pot before new leaves germinate or burying the base fertilizer in the pot soil every spring.

Reason 2: Water shortage.

Gardenia likes floods, as the saying goes: drought will not kill jasmine, and waterlogging will not kill gardenia. Too little watering obviously can't meet the requirements of gardenia.

Solution:

As long as there is no water in the basin, try to increase the water supply.

Reason 3: The air humidity is low.

Gardenia is a flower in the south, and it likes warm and humid climate. If the air humidity is too low, it will cause bud drop.

Solution:

Therefore, gardenia needs to grow in a high humidity environment during the maintenance process, and can be sprayed on the leaves often with a watering can.

Reason four: the influence of harmful gases.

Sulfur dioxide, hydrogen sulfide, etc. All affect the growth of gardenia. For example, the air pollution is heavy, and the content of such gases is high, which will cause poor growth of gardenia and insufficient nutrient reserves, and more buds will fall off after budding in the next year.

Solution:

Move gardenia out of places with serious air pollution in time.
