What happens when the leaves of the fragrant vine turn yellow and fall off after the leaf edges with

There are the following reasons why the leaves of the fragrant vine turn yellow and fall off after the leaf edges wither:

Dry yellow: the yellow of lack of water is not the same as the yellow of more water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

Lack of fat yellow: It is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow. It is necessary to check the potting soil frequently, if there is a dry knot phenomenon, the soil should be replaced, and the thin fertilizer should be applied diligently, and some alum water should be poured in a timely manner to replenish iron.

Lack of light yellow: If the leaves are shaded for a long time, the leaves cannot get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off, and the disease can be avoided by supplementing light.

Fat yellow: the yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in the dry brown appearance at the top of the new leaves, the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

Burning yellow: strong sunlight directly shines on some shade-loving flowers (such as spider plant, hosta, etc.), which is easy to cause the leaf tips and leaf edges of flowers to wither, and the sunny part of the leaves to appear yellow spots. Move to the pubic area.

Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.

Dipladenia sanderi (scientific name: dipladenia sanderi) is a new type of vine, also known as red wrinkle vine, double glandular vine, double happiness vine, Wen vine, red cicada flower, native to the American tropics, is a perennial evergreen plant of the oleander family.

The winding stems of the fragrant vine are soft and flexible, spiraling up along the support, and the pink trumpet-like flowers are large and straight, and the flower stems can reach 6 8 cm.

Fragrant vine prefers a warm and moist environment, but it is not well branched. During the flowering period, the fragrant vine often presents a grand situation of more flowers than leaves, and the breeze blows, and the gust of fragrant fragrance makes people feel refreshed and happy, so it has the elegant name of "fragrant vine".

Why do the leaves of the fragrant vine turn yellow? The most common reasons are here, see which one you belong to.

There is no need to be afraid of the yellow leaves of the fragrant vine, which is generally due to these reasons.

If the temperature is too high: the temperature is higher than 35 or lower than 10, and the fragrant vine will grow poorly, resulting in yellow leaves and leaf loss. Improper watering:

The plants are dry and dehydrated, and the leaves fall off easily. Too much fertilization: Frequent fertilization during growth, or too much fertilizer, can be affected.

Lack of light: The fragrant vine is in the shade for a long time, and the light is insufficient.

1. The temperature is too high

Piaoxiang vine belongs to tropical plants, the temperature requirements are relatively high, the temperature is too high or too low will affect its development, resulting in leaf shedding, if the temperature is higher than 35, the branches and leaves will be dry, yellow, if the temperature is lower than 10, the plant will wilt and freeze.

2. Improper watering

If the plant is dry and lacks water, the leaves are also easy to fall off, but the fragrant vine is not resistant to waterlogging, and the watering can not be too much, especially not stagnant water, otherwise it will lead to root rot, and even death in severe cases.

3. Too much fertilization

Piaoxiang vine needs a certain amount of nutrients in the growth process, but too much fertilizer, or too much fertilizer used, it is easy to cause damage to the root system, resulting in the phenomenon of yellow leaves and leaf loss.

4. Lack of light

Fragrant vine is suitable for growing in a sunny environment, if it is in shady conditions for a long time, the plant will be stunted, resulting in leaf shedding, usually put it in a sunny place, receive the light of the whole day, basking in the sun not only allows the fragrant vine to better photosynthesize, but also helps flowering.

The reasons for the yellowing and falling off of the leaves of the fragrant vine include strong light, physiological yellow leaves, excessive watering, excessive fertilization, etc.

1. The light is strong

In summer, the temperature is relatively high, the light is strong, it is easy to sunburn and yellowing, the yellowing edge of the sunburned leaves is accompanied by the symptoms of dryness, and yellow spots will appear.

2. Physiological yellow leaves

If the yellow leaves appear on some old leaves at the base, then don't worry, this is physiological yellow leaves, a normal phenomenon, the leaves also have a lifespan, after a long time, the old leaves at the bottom will slowly turn yellow and fall, and the new leaves on the top will continue to grow, like this kind of normal falling leaves to a certain time you touch him lightly will fall, this is a normal elimination of a process, don't worry.

3. Overwatering

If you find that the fragrant vine has a large area of yellow leaves, and the new leaves are relatively yellow, and the old leaves have no problems for the time being, it is likely to be caused by too much watering and stuffy roots. You can observe the state of the potting soil, if it is wet, then we need to move it to a ventilated place for maintenance, can no longer water, reduce the number of watering, feel serious friends can pour out in time to prune the roots, repot.

4. Too much fertilization

If the top of the new leaves of the fragrant vine is dry brown, and the leaves are uneven, this is what we often say is caused by excessive fertilization, and it is necessary to stop fertilizing in time, or reduce the frequency of fertilization, you can reduce the concentration of fertilizer in the soil with appropriate watering, and put it in a well-ventilated place outdoors after watering.
