What are the good suggestions for dry and fallen leaves?

Timely removal of diseased leaves, cleaning of fallen leaves, and concentrated burning, can reduce the source of disease.

Strengthening water and fertilizer management, increasing potassium fertilizer, and avoiding soil drought or water accumulation can increase plant disease resistance.

At the beginning of the disease, you can spray 500 times of propiconazole emulsifiable concentrate with 25, and then pour it again after a month, or use more than 40? 500 times of sulfur suspension, once every 10 days, 2 to 3 times in a row, or spray with 50 times of 50 benzelat wettable powder, once every 7 days to 10 days, 2 times to 3 times.

As far as I know, the main causes of leaf loss are red spiders, coal stain disease, and watering too often, so it is recommended not to water too often, so let the potting soil see dry and wet. ‍‍

It is necessary to replenish nutrients, water more, and put it in a sunny place for a while every day.

Give it some nutrients, water it more or give it loose soil.

In late autumn and early winter, the diseased leaves should be completely removed and burned or buried in a concentrated manner to reduce the overwintering bacteria, which can effectively inhibit the occurrence of the disease in the next year. ‍‍

It is best to put it in this greenhouse, so that it is not easy to cause dry and fallen leaves.

Lack of nutrients, need to loosen the soil, water and fertilize, and get more exposure to sunlight.

Flowers are generally due to temperature and humidity problems cause the leaves to fall, if the temperature is not lower than 15 degrees, please water, please be sure to see dry and wet, especially in winter, try to water as little as possible, do not fertilize.

It is necessary to pay attention to its soil, temperature, and watering and fertilization. You can go to the florist and ask. Let it teach you what you know.

It's like a person who looks very haggard and must be lacking in nutrients, go to the market and buy some nutrient solution and put it on the flowers.

We know if it's dry. It is likely that the water will flow more quickly, and the water from the trunk to the leaves will be affected. When this happens, the tips and edges will dry out, and it is important to hydrate at this time.

If there is no sun and there is a lot of rain, the new branches are likely to be brittle and tender, and there will be more water. If the sun suddenly shines, it is very likely that the tips of its leaves will be dried, and if the situation is more severe, all its leaves may dry out. So at this time, we still put it in a dark place, and wait a day or two for it to recover on its own.

If it lacks nutrients, the leaves may be dry, for example, its roots will not have enough oxygen or potassium, and its growth will be affected. At this time, all we have to do is to use compound fertilizer, in addition to a certain amount of pruning on it. Because it makes it more nutritionally balanced, many cells can be exposed to light.

It can not only save the withered leaves, but also make its tree shape beautiful.

Of course, if you have been to our potting soil is finer, there may be a lack of humus. In this way, respiration will be affected, and the edges of the leaves will dry up easily. So we have to replenish it in a timely manner.

Insect infestations can also cause its leaves to dry out, so we still use insecticides to solve this problem. And it's better to find it early and deal with it early, because if it is difficult to solve it after a long time, it may cause it to die.

If the tree is older, it is also likely that its leaves will dry out. Because the tree is evergreen, it still needs to be metabolized, so the leaves are likely to die the next year because its chlorophyll cells have long since become old. In addition, the old leaves are still in the lower part, so they will be grinded, so drying up is also the norm.

1. Soil

Sijigui likes slightly acidic soil, if it is too acidic, it will cause Sijigui to grow slowly and the leaves to wither and yellow, if it is alkaline soil, then after 2 or 3 months, the leaves will wither and even die.

Treatment method: The soil of Sijigui can be mixed with humus or peat, garden soil, sandy soil or river sand (the ratio is 5:3:2), and the pH should be kept at it. The culture soil is sterilized with potassium permanganate solution before potting.

2. Watering

The soil of osmanthus should have good air permeability and be afraid of waterlogging. So if you don't water it in the right way, it will also cause the bay leaves to dry up.

Treatment: It is best not to dry and not water, and water thoroughly each time. Afraid of waterlogging and waterlogging, if it is harmed by waterlogging, the root system will be black and rotten, the leaf tip will be scorched and withered, and then the whole leaf will wither and fall off, which will lead to the death of the whole plant.

3. Temperature

The right temperature plays a very important role in the growth of the four seasons laurel, if the temperature is too high or too low for a long time, it will cause the leaves of the four seasons to dry up.

Treatment: In the environment of high temperature or dry environment, the method of shading and spraying is used as much as possible to improve the environmental humidity. Generally speaking, it is the tip of the old leaves, and it can be improved as long as the humidity is increased by more than 60bf.

4. Missing important elements

Plants lack vital elements and lack oxygen or potassium in their roots. When the potting soil is too fine and lacks humus, the respiration of the roots is obstructed, and the breathing is not smooth in the longer stage, which will affect the dry edges of the leaves; Potting soil with insufficient potassium also causes the tips and edges of the leaves to dry out.

Treatment: At this time, in fact, there is no need to worry too much, as long as the appropriate compound fertilizer can achieve results quickly, after growing for a period of time, the dried leaves of the four seasons will regain their vitality.

5. Germs

Brown spot disease, in the early stage of the disease, there are small yellow spots on the leaves, which gradually expand into nearly round lesions, brown spot disease generally occurs from April to October, the old leaves are more susceptible to disease than the young leaves, and the leaf dryness caused by the fungus is the most difficult to treat.

Potted osmanthus should be removed from diseased leaves in time. Secondly, strengthen cultivation management. Choose fertile, well-drained soil or substrate for planting osmanthus; increase the application of organic and potash fertilizers; The planting density should be appropriate to allow ventilation and light transmission, reduce foliar humidity and reduce the occurrence of diseases.

Scientific use of pesticides for prevention and control.

The fall off of the leaves of the four seasons osmanthus may be caused by too much water, so it is necessary to water less.

Although osmanthus likes light, but is more afraid of direct exposure to strong light, if it is irradiated by light for a long time, the water evaporation of the leaves is too fast, affecting the normal photosynthesis of the leaves, and the leaves will dry up and become brittle. It is enough to ensure 6 to 7 hours of sunlight every day, like the strong sun in summer and at noon, then use a sun visor to block it.

If the leaves of osmanthus flowers that have been cultivated for 1 or 3 years dry up, it may be due to the deterioration of nutrients and quality in the soil substrate. Watering, fertilizing, etc., can contain residues, which over time will change the pH and softness of the soil. In addition to loosening soil, the simplest and most crude way is to replace the loose and nutrient soil rich in organic matter.

Osmanthus maintenance skills

Osmanthus likes a warm and humid growth environment, and the choice of cultivation soil should be fertile, loose, draining and breathable slightly acidic loam soil, and the most taboo is the soil with large stickiness and high alkalineness. For family pot cultivation of osmanthus, you can choose peat soil, garden soil and vermiculite rich in organic matter mixed to make cultivation soil, and it is more suitable to choose a mud pot or ceramic pot with a diameter of 20 30 cm and a depth of 35 40 cm.

The suitable growth temperature of osmanthus is about 18 28 degrees, not tolerant to severe cold, the northern region breeds osmanthus, and needs to do a good job of antifreeze protection in winter, otherwise it will frostbite the leaves, affecting the growth of the new year. Osmanthus likes to moisten and taboo waterlogging, watering osmanthus to dry on the surface of the pot soil, fingers pick up the surface of the pot soil below 2 cm to see the moisture can be watered through, but avoid water accumulation in the pot.

Sijigui is suitable for growing in warm, moist and sunny places. The soil should be fertile, loose, slightly acidic and well-drained. Four seasons of Gui compete.

It is drought tolerant and cold-tolerant, its growth temperature is 20-30, and if there is no special cold wave in winter, it can generally overwinter in the open ground.

The leaves fall in winter due to poor drainage, or the leaves fall off due to cold wind blowing and frosting, and the lack of sunlight and ventilation can also make her fall leaves. Indoor cultivation should be placed in a sunny and ventilated place, and the light should be kept at 8 to 12 hours a day. The four seasons are warm and generally grow well between 18 and 25 years old, with many flowering and fragrant flowers.

If it is below 15, it is semi-dormant and has less flowering. 3 to 5 can survive the winter, but not flowering. Cultivating four seasons cinnamon should not only keep the potting soil moist, but also not too waterlogged.

When watering, it is necessary to see dry and wet, and avoid stagnant water, so as not to rot the roots or fall off the leaves. Especially during flowering, water should not be too much, so as not to cause budding and affect flowering.

The common causes of yellowing of the four seasons laurel leaves are:

1.Yellowing – prevented with fungicides such as carbendazim or mancozeb or meazine tobson.

2.Replacement of old and new leaves.

3.Improper management of fertilizer, water, light and wind - like moist and fertile acidic soil, can be appropriately applied ferrous sulfate solution (sold in the flower market) to water the roots; When the temperature is 15-25 degrees, it can be watered once in 7-10 days, and it is better to increase foliar spray if there are conditions; Avoid strong winds, especially hot and dry winds; Avoid direct sunlight and increase scattered light; Airy.

1. Overwatering.

The leaves of the potted osmanthus tree fall off, which may be a problem of too much water, and the osmanthus is a drought-tolerant plant, so don't water it too often.

Too much water will cause the potting soil to produce stagnant water, which will make the roots of Sijigui unable to breathe, which will cause poor growth, root rot, and yellowing and falling off the leaves.

2. Uncomfortable temperature.

Osmanthus is a woody plant and is not suitable for too long indoors in summer.

Generally, it should be put outdoors for about 2-3 days, let it bask in the sun and drink dew, otherwise the osmanthus will fall off the leaves or the leaves will turn yellow, and finally die.

3. Leaf blight.

Leaf blight can occur at any time of the year, and the disease will cause a large area of the leaves of the four seasons to wither and fall off.

Causes and rescue measures for the loss of leaves of osmanthus in all seasons:

1. Four seasons osmanthus trees turn over the soil.

When the osmanthus tree is purchased, whether to bring a flower pot, the osmanthus tree is repotted, resulting in a long recovery time for the root injury of the osmanthus tree.

Remedy: If the root damage is not severe, new leaves can be generated. Observation is not good, pruning to save life.

2. Place the osmanthus tree outdoors.

Osmanthus is a woody plant, not suitable in summer, not suitable for indoors for too long, generally put about 2-3 days should be put outdoors for about a week, let it bask in the sun, drink dew, otherwise the four seasons osmanthus fall off the leaves or the leaves turn yellow, and finally die.

3. Watering the osmanthus tree in all seasons.

1) Watering too little.

The water is not done well, because the laurel tree grows in the pot for a long time, the water we water when watering does not soak the pot soil, but flows directly from the edge of the pot, causing the laurel tree to lack water.

If this is the case, you can fill a container slightly larger than the pot with water, and placing the entire pot in the water and letting the potting soil absorb the water should do the trick. After the laurel tree recovers vigorous growth, it will be repotted at a certain time.

2) Overwatering.

Osmanthus tree leaves fall off, too much water problem, four seasons osmanthus is a drought-tolerant plant, watering should not be too diligent, potted soil poor drainage or too wet, will cause poor growth, root rot, leaf shedding.

This situation requires less watering.

Too much water will cause leaf loss.

Phenomenon, the pH of the water is too high will also cause the phenomenon of yellow leaves falling off, and ferrous sulfate should be added appropriately in the water.

How to raise a potted four-season osmanthus tree.

1. Gui likes light in all seasons, and indoor cultivation should be placed in a sunny and ventilated place, and the light should be kept at about 8 hours a day.

2 The four seasons are warm, and the suitable temperature for growth is 18 to 25. If the temperature is lower than 15, it is semi-dormant. The temperature is between 3 and 5 to survive the winter, but it does not bloom.

3. To raise four seasons cinnamon, it is necessary to keep the potting soil moist and not waterlogged. When watering, it is necessary to see dry and wet, and avoid stagnant water, so as not to rot the roots or fall off the leaves. Especially during flowering, watering should not be too much, otherwise it will cause bud drop and affect flowering.

4 fertilization Four seasons Gui likes fertilizer, during germination and bud pregnancy, more diluted fertilizer containing phosphorus and potassium should be applied to make the branches and flower buds grow strong and lush, especially in the first few days of flowering, apply some diluted fertilizer water, which will make the flowers large, bright and fragrant. Small arbor, four seasons laurel. In the second year, the tree will be full of golden flowers, with large flowers and strong fragrance, and the flowering period will last for half a year.

This is a fortune tree, not an osmanthus tree. Water less.

This armpit is underwatered, can't be **, water more, remember to bask in the sun more, it's okay.

Precautions. Clause.

1. Tidying up the ground: do not apply bottom fertilizer before tidying up the osmanthus seedling field, tidy up and level each piece of the field planted with osmanthus seedlings, and there must be no stagnant water in the field, so when tidying up, you must leave a drainage ditch in order to eliminate stagnant water.

Clause. 3. Watering after planting: water can not accumulate in the field, but it does not mean that it will not matter after planting, it is necessary to water after planting seedlings, and the soil of the field should be watered thoroughly, but it is also necessary to pay attention to the water not to accumulate in the ground.

Clause. 4. Post-planting fertilization: After planting, you need to wait until the roots of the seedlings are strong before fertilizing, but only a small amount of farm fertilizer can be applied. The planted osmanthus seedlings do not need to be fertilized in the early stage of planting.
