Penglai pine leaves have fallen off, is it dead

Penglai pineIf the leaves fall out, they are dead.

Loose leaves can be caused by improper maintenance, and the common cause is improper watering, that is, too much watering and too little watering. If the leaves are caused by excessive water application, then you need to stop watering immediately, and at the same time loosen the soil for it, so that the water can seep out as soon as possible. If it is caused by insufficient watering, then it is necessary to replenish the water of the plant immediately, but not too much, and it is necessary to spray some water on the leaf surface appropriately.

Basic introduction. Overwatering: When maintaining Penglai pine, water it too much, the potting soil will accumulate water, and the roots will be unable to breathe normally in a moist environment for a long time, resulting in the rot of some fibrous roots, and the ability of the roots to absorb water and nutrients will be weakened, causing leaf drop.

Too little watering: If you don't water enough when maintaining Penglai pine, the water evaporation of the leaves is greater than the absorption, and the leaves will dry up and shrunk, and then they will fall.

In order to prevent the yellow leaves of Penglai pine from falling leaves, it is necessary to pay attention to proper fertilization, usually fertilization is applied every half a month during the growth period, mainly nitrogen fertilizer, and the fertilization during the mature period is generally based on phosphorus and potassium fertilizer, and the appropriate amount of fertilization can avoid the leaves turning yellow and falling leaves.

It should be certain that it can't be restored, in fact, as long as you know a basic rule, once all the leaves of evergreen plants have fallen off (artificially pruned are not counted), there is a high probability that it will not be able to be saved.

Penglai pine is a perennial evergreen herbaceous plant.

The pine can be cut off and regrown, but a part of the trunk should be retained to germinate new shoots. The growth rate of Penglai pine is fast, easy to maintain, if it grows too tall, it should be pruned in time, and the long part can be cut off to control the height of the potted plant; If the leaves are yellow, dry or have other serious problems, you can also cut off most of the branches and let them grow again.

The best growth temperature is about 30 degrees, and the minimum temperature should be kept at about 3 degrees, but it should not be exposed to the sun and stagnant water, and it will stop growing when the temperature exceeds 35 degrees.

It is better to use clay pots for planting Penglai pine, and the soil should be mixed with good ventilation, good drainage and rich nutrients.

Pot selection:

Penglai pine should use purple sand pottery pots, and glazed pottery pots can also be used. Just planted in a pot, you can first use a plain pot with good air permeability, and then change it into a shallow pot with elegant purple sand after serving the pot.

In addition to the cliff type with deep thousand cylinder basins or deep square and round basins, it is generally advisable to use rectangular shallow basins. The shape of the pot can also be determined according to the shape of the tree, such as the drum-shaped shallow round pot can be used for the curved dry type, and the pot color can be purple red or light yellow.

Penglai pine can adapt to a variety of soils, but is not tolerant to salinity, and is better than deep, moist, loose and slightly acidic sandy loam soil. Potted plants are used with ripened garden soil and humus soil, mixed with sandy soil in an appropriate amount. It is best to plant Penglai pine in pots before budding in March, and it can also be planted in autumn, but it is not conducive to rooting.

After pruning the pine, it is necessary to spray carbendazim on its fracture to avoid the plant from being infected with diseases, and the pine should be placed in a bright place to let it receive all-weather light.

When cultivating Penglai pine, it is necessary to spray carbendazim on its fracture after pruning the plant to avoid the wound of Penglai pine from rotting due to disease infection, and wrap the branches of Penglai pine with plastic film, and move Penglai pine to a ventilated semi-shaded place to restore healing.

Penglai pine planting tips.

1. Lighting conditions.

Penglai pine is a sun-loving plant, when cultivating Penglai pine, it needs to be placed in a bright place, so that the plant receives all-weather light, promote the photosynthesis of Penglai pine, which is conducive to the rapid growth of new leaves, but when the light is too strong, do a good job of shading measures for Penglai pine.

2. Maintenance management.

When maintaining Penglai pine, it is necessary to water according to the dryness and wetness of the soil, so as to avoid water accumulation in the soil, and after Penglai pine grows new leaves, it is necessary to apply a nitrogen-based compound fertilizer to promote the germination of side branches of the plant, and regularly spray potassium dihydrogen phosphate on the leaves of Penglai pine to make it more lush.

OK. Penglai pine can be cut off and re-grown, because the growth rate of Penglai pine is faster, after all the leaves are cut off, the plant shape can be more beautiful, when cultivating Penglai pine, you need to use sharp scissors that have been sterilized with alcohol to prune, so as not to be infected with diseases of Penglai pine.

When cultivating Penglai pine, it is necessary to spray carbendazim on its fracture after pruning the plant to avoid the wound of Penglai pine from rotting due to disease infection.

rotten, and wrap the branches of the pine with plastic film, and move the pine to a ventilated semi-shaded place to heal the wound.

Maintenance method. 1. Temperature. Penglai Songxi has a slightly higher environment. Between 20 and 30 degrees, it is more suitable for Penglai pine. It has a hardy ability to withstand cold, and in winter, it can tolerate temperatures as low as three degrees. It's better not to go any lower, though.

2. Illumination. Penglai pine doesn't like bright light, but it can't be completely dark either. Therefore, a semi-shady place is the most suitable for it. During the season when it grows, it can be placed in semi-shade with a little astigmatism.

Especially in summer, be sure to shade out the light. In winter, the light is not particularly strong, so try to place it in a well-lit place.

3. Watering. It is a moisture-loving plant, but it must not accumulate water either. During the growth period, it should be appropriately supplemented to ensure that the soil is slightly wet. There is basically no need to water in winter, and you can water a little bit when the soil is too dry.

Hello, the growth temperature of Penglai pine is between 20-30, and the winter temperature can be safely overwintered if the temperature is above 3. Light: Sufficient sunlight should be ensured in winter, and the high temperature in summer should be moved to a well-ventilated semi-cool place for maintenance.

Watering: Sufficient water should be given during the growing period to avoid water accumulation in the potting soil; When the temperature drops in autumn, watering should be gradually reduced. Fertilization:

During the growth period, fertilizer is generally applied once a month, and more nitrogen and potassium fertilizers are applied.

Cultivation methods. Temperature and light.

The suitable growth temperature of Penglai pine is between 20-30, and the winter temperature can be safely overwintered if the temperature is above 3. In winter, it is necessary to ensure sufficient sunlight for Penglai pine. In the summer high temperature season, Penglai pine should be moved to a well-ventilated semi-cool place for maintenance, so as to avoid scorched leaves and fallen leaves due to strong direct light, and reduce the ornamental value of the plant.

During the growth of watering Penglai pine, it is necessary to give the plant sufficient water to promote its growth, but pay attention to avoid water accumulation in the potting soil, otherwise it can easily lead to root rot. In autumn, when the temperature drops and the growth of the plants begins to weaken, watering should be reduced gradually.

During the fertilization and growth period, fertilizer is generally applied once a month, more nitrogen and potassium fertilizers are applied, and it is recommended to choose water-soluble fertilizers that are better absorbed, such as Ribery Yanwo water-soluble fertilizer, which has a high utilization rate and is easy to be absorbed.

The soil requirements for the soil are not strict, and it is suitable to choose loose aeration, well-drained, humus-rich sandy loam.

The yellowing of the leaves of Penglai pine is rescued as follows:The yellowing of the leaves of Penglai pine may be due to too much watering, too much water is prone to water accumulation, so that there is no oxygen in the soil, so that the roots of Penglai pine have no way to breathe, resulting in root rot. At this time, we should carry out proper loosening treatment, drain the water, and then put the Penglai pine in a ventilated place for maintenance.

If the fertilization is improper, the leaves of the pine will also turn yellow, too much fertilizer too little, will have an impact on the growth of the pine, if the fertilizer is too little, the growth of the pine will lack nutrients, its branches will become thin, and if it is serious, it will also turn yellow, at this time, we need proper fertilization to supplement nutrients, if there is too much fertilizer, it will have an impact on the root growth of the pine, the leaves will be yellow, at this time you can dilute it with water, you can also replace the soil.

If the light is too strong, the leaves of the pine will also turn yellow, when we are maintaining, the light is insufficient, it will make the leaves of the pine thinner, at this time, we need to put it in a place of astigmatism to maintain, proper shade.

Light Light is a very important element for flowers, and it is also a science, insufficient light or too much light may affect the growth of flowers. Penglai pine is a sun-loving flower, if it is left indoors for a long time, it cannot be exposed to sunlight, and the leaves will turn yellow. Once this symptom is found in a shady place, it should be moved to a sunny and ventilated place immediately.

Soil Another factor in the yellowing of the leaves of Penglai pine is the soil problem, although the soil quality requirements are not strict, but it is better to use sandy soil rich in humus. If you can't prescribe the right medicine after ruling out other reasons, the owner has to look at whether the soil is qualified.

Watering Many friends who don't know how to raise flowers may be a relatively difficult problem for watering, and grasping the amount of watering is the key factor in raising flowers. Penglai pine should be watered when the soil surface in the pot is dry, and must be watered thoroughly, not too much waterlogging, and can not only be watered half of the stop.

Although Penglai pine is afraid of high temperatures, it likes warmth, and placing it in a place with good sunlight scattering conditions can effectively prevent the leaves from yellowing.

It is not drought tolerant, and it needs to be watered thoroughly when alternating between dry and wet, without too much. If the foliage is too dense and it is in the summer heat, it will also cause the leaves to turn yellow, and it is time to build the branches.

1. Situation. 1. Insufficient or too strong light: Penglai pine is a light-loving plant but not tolerant to strong light, so if it is placed in a cool place for a long time or strong light for a long time, it will make the leaves yellow.

Solution: Move it to a sunny place in winter, and properly shade or move to a cool place in the summer during the high temperature season.

2. Situation. Second, the soil is unqualified: Penglai pine does not have high requirements for soil, suitable for growing in a loose, fertile, well-drained and humus-rich environment, if the soil is hard or poorly drained, humus is not rich will make the leaves yellow.

Solution: Replace it with humus-rich sandy loam soil in time, and then water it with an appropriate amount of water and put it in a sunny place for a period of time, and the leaves will return to green.

3. Situation. 3. Too much watering: Penglai pine is not drought tolerant, but also afraid of waterlogging, if too much watering or not watered for a long time, will make the sleepy leaves yellow.

Lead shouting solution: If the potting soil is too wet, you can remove the plant with the potting soil, put it in a cool place for two days, and finally transplant it into a pot, after a while, the leaves will return to color. If it has not been watered for a long time, it can be watered thoroughly when it is dry and wet.
