Why do the edges of the leaves turn red on the longevity flowers

Cause of reddening. First of all, the leaves of longevity flowers turn red not because they are sick, this is a normal phenomenon, so flower friends can rest assured.

Reason 1: Because as the temperature decreases, the leaves of the longevity flower will turn red.

Reason 2: If the light becomes stronger, and you give the longevity flower too long to the light, the leaves of the longevity flower will also turn red at this time, reason 3: If there is a lack of water, and the sunlight is also irradiated, then the leaves of the longevity flower will also turn red.

What to do. The reddening of the leaves of the kalancho will not affect the growth, and if you want the reddened leaves to turn green, then you can do the following:

First of all, move the longevity flower to the maintenance position, you can move it to the place of astigmatism for maintenance, and then pay attention to watering more water appropriately to ensure that the leaves can absorb water and begin to become tender, so that the leaves will gradually return to their original green color after a few days.

Secondly, when the longevity flowers grow in the summer, reduce the amount of watering, and also put the longevity flowers in a cool and ventilated place for maintenance, so that the leaves will not turn red.

Finally, in the cold winter, pay attention to cold protection, prevent frostbite plants, leaf redness and other symptoms. In addition, in winter, Bikagen can be used to prevent frost damage.

Be sure to pay attention to adequate light, but do not shine too long and do not shine in direct sunlight.

It is also necessary to pay attention to the usual ventilation work.

This is usually due to high light intensity and low ambient temperature.

Longevity flower leaves curl yellowing cause:

1. The potting soil is too dry and lacks water.

Longevity flowers are succulent plants, more drought-tolerant, so many flower friends longevity flowers are not watered after buying, or watering very little water each time, plus the cultivation substrate is better permeable, or relatively dry, watering is not easy to absorb water, often or once watered through, longevity flowers should be drought and lack of water after a long time, resulting in curl of leaves.

If the potting soil is very dry, obviously united, and there is a large gap between the edge of the pot, this is a manifestation of the potting soil is very dry, the pot should be soaked in water for about 30 seconds, take out and drain the excess water, and the potting soil should be kept slightly moist during the flowering period.

2. Caused by fertilizer damage.

In addition to drought and water shortage, sometimes improper topdressing can also cause the leaves of longevity flowers to curl and the leaf edges to turn yellow and dry. Generally, it is recommended to stop fertilizing in Citi to avoid fertilizer damage leading to the reduction of the ornamental value of longevity flowers, and nitrogen, phosphorus and potassium compound fertilizers can be applied after flowering to help longevity flowers recover, and phosphorus and potassium fertilizers should be applied once a week at the bud stage to promote the growth of flower buds, and top dressing should be stopped during the flowering period.

3. Rotten roots.

Longevity flower leaves curl and yellow most often caused by rotten roots, longevity flowers can not be watered more, otherwise it is easy to rot roots, especially in indoor breeding, poor ventilation conditions, watering after the pot soil does not dry for a long time, it is easy to cause stuffy roots.

However, a large amount of water is stored in the stems and leaves of longevity flowers, which is generally not easy to find in the early stage of root rotten, only the leaves gradually become curled, dry, soft, and when the air humidity is relatively high, there will be some aerial roots.

Key points of longevity flower maintenance.

After watering the longevity flowers, it is best to put them in a well-ventilated place to let the excess water be lost as soon as possible, and the potting soil should be made of a substrate with good water permeability and air permeability, and the heavy clay soil is not suitable for planting longevity flowers.

Before each watering, you should insist on the dryness and humidity of the potting soil, and then water when the potting soil is relatively dry, or directly soak the pot in the water for about 30 seconds, when soaking, the potting soil will bubble, and when there are no bubbles, you can end soaking the pot.

The redness of the leaves of longevity flowers may be due to low temperature, insufficient moisture, and too much light. If the plant is exposed to less than 5 degrees Celsius for a long time, the soil is dry for a long time, the plant is seriously dehydrated, or has been exposed to sunlight for a long time, the leaves will be red, as long as it is well maintained.

1. The temperature is too low

The redness of the leaf edges of kalancho flowers is most likely due to the low ambient temperature. It is a plant that prefers a warmer environment, and the temperature around it is generally controlled between 12-15 degrees Celsius during winter maintenance, and if it is lower than 5 degrees Celsius for a long time, the plant will turn red due to frost.

2. Insufficient moisture

Longevity flowers like to grow in a slightly moist environment, in addition to paying attention to dry and wet during daily watering, we also need to spray some water mist to maintain its humidity. If the plant is left in a state of drought for a long time and there is a severe shortage of water, the leaves will be red.

3. The light is too strong

Longevity flowers need sufficient scattered light irradiation to photosynthesize in the process of growth and development, give birth to leaf buds, and grow stronger, but this plant is a short-day plant that cannot withstand long-term exposure, and if the longevity flowers are exposed to sunlight for a long time, the leaves of the plant will be red because of burns.

4. Precautions

After the leaves of the longevity flower are red, we should not rush to prune and remove the work, unlike the withered leaves, the redness of the leaves is a very common maintenance mistake, which can be controlled by light, watering and temperature to slowly restore the plant to its original state, so you only need to do a good job of maintenance, do not rush to prune.

Reasons for the redness of the leaves of longevity flowers: too large temperature difference or too low temperature, sufficient sunlight, insufficient watering, lack of fertilizer.

1. The temperature difference is too large or the temperature is too low

If the longevity flower is raised in the open, when the temperature difference is too large or the temperature is too low, the photosynthesis ability is weakened, and the chlorogen content of the leaf Zheng belt is reduced, and the leaves will gradually turn red from the leaf tip and spread to the entire leaf surface. Large temperature difference and low temperature are not conducive to the budding and flowering of longevity flowers, so the minimum temperature of longevity flowers in winter can not be lower than five degrees, and the maximum temperature difference cannot be higher than ten degrees.

The most suitable temperature for long-lived peanuts is 15 to 25 degrees, and the temperature difference is kept within 10 degrees. When it is found that the leaves of longevity flowers are red due to low temperature or high temperature difference, they should be moved to a warm place with a small temperature difference in time for maintenance.

2. Sufficient sunlight and insufficient watering

Some flower friends' longevity flowers do not grow buds for a long time, so they will increase the light and reduce watering, which is what we call water control. There must be a degree of water control, if the control is too strong, the leaves of the longevity flower will turn red. The reddened leaves have reduced photosynthesis and are more difficult to flower.

Therefore, if the leaves are a little wilted, they should be watered, and they will be too much to seep and rot. Even if it is not for flowering, it is necessary to water it in time and do not make the leaves dry red.

3. Lack of fertilizer

If you do not fertilize the longevity flower for a long time, or the fertilization is too simple, and some trace elements are missing, the longevity flower leaves will also turn red in the case of sufficient light. Therefore, it is best to use some special fertilizer for flowering flowers during flowering and budding, so that it is not easy to have red leaves due to lack of fertilizer.

Growth habits

Longevity flowers are autumn bulbous greenhouse flowers, which like full sunlight, tenacious vitality, can tolerate semi-shade, and are not cold-tolerant. In July and August, the leaves are dormant, and the flower buds are differentiated at the growth point of the bulb during the dormant period, which has the physiological characteristics of autumn and winter growth, early spring flowering, and summer dormancy.

Longevity flowers like light, water, fertilizer, suitable for warm, humid climatic conditions, like fertile sandy soil. It prefers coolness in the early stage of growth, slightly hardy in the middle stage, and warm in the late stage. Therefore, it is required to have no severe cold in winter and no heat in summer, and rainy climate and environment in spring and autumn.

During the day, longevity flower pots should be placed in a sunny place with plenty of sunlight to give them plenty of light. Because plants need chlorophyll to provide nutrients through photosynthesis, so that the leaves of longevity flowers can be wide and straight, the leaf color is bright green, and the fragrance of flowers is tangy. On the contrary, the leaves are tall and thin, weak, and the leaf color is yellow, or even does not bloom.

It is best to use loose and fertile alluvial sandy loam soil with deep cluster leakage layer, and it is suitable for growth when pH is high.

<>1. First of all, the leaves of longevity flowers turn red not because they are sick, this is a common phenomenon, so flower friends can rest assured.

2. Reason 1: Because as the temperature decreases, the leaves of longevity flowers will turn red.

3. Reason 2: If the light becomes stronger, and you give the longevity flower too long to the light time, at this time, the leaves of the longevity flower will also turn red, reason 3: If there is a lack of water, and the sunlight is also irradiated, the leaves of the longevity flower will also turn red.
