What to do if the leaves of celery peony turn yellow after being repotted

Generally speaking, peonies can only be planted in autumn, not suitable for spring planting, that is, the so-called "spring equinox planting peony, no flowering to old age". This is because the root system of peony begins to move in early spring, and the scale buds germinate in early March, and then the branches and leaves are pulled, and the buds bloom, which consumes a lot of nutrients and water; And the temperature in spring is getting higher, drought and windy, if the roots are injured due to planting, it will greatly affect the absorption of water and nutrients by peony, resulting in insufficient water and nutrients, and it is difficult to survive, or the growth and development of poor growth after survival, and no flowering. So for a long time, people have formed the habit of transplanting peonies in autumn.

However, this does not mean that peonies should never be transplanted in spring. If you can transplant with soil balls and maintain them properly, peonies can not only survive but also bloom well.

The time for transplanting must be early. Peonies are relatively cold-tolerant, and root activity begins earlier in spring, and early migration can improve the survival rate.

Spring transplanting must be carried with a mound of soil to protect the roots from injury.

Immediately after transplanting, water once to keep the soil and roots tightly connected to the wind.

1. Water yellow. The leaf yellow caused by long-term watering is manifested in the young leaves are dull, and the old leaves have no obvious changes and the roots are thin.

Small yellow-green, the new shoots shrank and do not grow, should be watered moderately, the heavy ones can be depotted, put in the shade to dry the soil and then re-pot.

Second, dry yellow. Yellowing of leaves due to lack of water or too little watering. The old leaves are yellow and shed from the bottom up, but the new leaves are generally raw.

Long normal. The amount and frequency of watering should be increased appropriately.

3. Fat yellow. Due to excessive fertilization or excessive concentration, the tips of the new leaves appear dry brown, and the tips of the old leaves are dry and scorched and yellow, and the leaves are generally leaves.

Although the surface is thick and shiny, most of it is uneven. Fertilizer should be stopped or rinsed with water.

Fourth, lack of fat yellow. Potted flowers are only watered for a long time without watering fertilizer, or not changing pots for many years, the roots are clumped, and the plants can not get fertilizer, so that they can not be fertilized.

The leaves are yellow, in addition to changing the pot in time, thin fertilizer should be applied frequently.

Celery leaf peony likes light, it is better to put it on the balcony in a bright and ventilated place, the soil is dry and watered, afraid of waterlogging, afraid of cold, afraid of freezing, afraid of cold wind.

1. The light is too strong.

Celery peony grows in semi-shade, and if it is subjected to strong light, the leaves of the plant can easily get sunburned, causing it to turn yellow. Therefore, it is important to pay attention to shading, especially in summer. It should be noted that it is a long-day plant, and long-term light is more conducive to flowering, so it is necessary to provide sufficient scattered light.

2. Lack of nutrients.

Celery leaf peony needs a certain amount of nutrients during the growth process, and if the fertility of the soil is too low, the leaves of the plant will also turn yellow if the fertilizer is insufficient. In addition to planting to apply sufficient base with fertilizer, the growth period should also be appropriate top dressing, the early fertilizer is more urea, the later stage is to use compound fertilizer, once a week can be applied.

3. The temperature is too low.

Celery peony prefers a cool climate, but too low temperatures can easily cause it to be frostbitten, resulting in yellow leaves. Usually during the day, the temperature is kept between 15-20 and 7-8 at night. In winter, it should not be lower than 0, otherwise it needs to be moved to the greenhouse for maintenance, or covered with a bag to keep warm.

4. The root is damaged.

If the roots of celery peony are damaged, it affects the plant's absorption of water and nutrients, and can also cause the leaves to turn yellow. In view of this situation, it is necessary to depot it in time, and after taking out the plant, use sterilized scissors to properly prune the rotten roots. Then prepare the new soil and replant it.

Pay attention to the amount of water and fertilizer, and at the same time maintain ventilation.

Peony flowers are fleshy roots, like moisture but afraid of waterlogging, are you watering too much, causing the leaves to wilt and lose energy, and the flower bones to die. Many friends are always afraid of their flowers lack of water, so they often water desperately, but they don't know that this just plays a counterproductive role, you know, plant growth needs to rely on the roots to absorb water to maintain the growth of its branches and leaves, but the roots need enough air to maintain, more water natural air less, long-term moisture will make its roots in a "suffocation" state, so how can flowers and plants grow well? Generally, long-term moisture plants will show "leaf yellow, wilting, slow growth, gray and dull leaf surface, and leaf loss", and long-term moisture will induce the invasion of many germs, and eventually lead to the death of flowers.

Peony watering must be at the right time, in the right place. In the dry climate in the north, the number of watering should be more, it is generally believed that watering 2 3 times before flowering, 2 3 times after flowering, 7 September during the rainy season do not need to be watered, after autumn depending on the weather and drought conditions and then watering 1 2 times; In the south, the weather is hot and rainy, so it is generally not necessary to water. Especially during the rainy season, it is necessary to pay attention to timely drainage.

The seedlings should be watered enough after 10 to 15 days. In addition, it is necessary to pay attention to the temperature when watering, watering in the early morning or evening in summer, and watering in winter and spring when the temperature rises. If the ground freezes unresolved, do not water.

In short, peony watering should be based on the principle of keeping the soil moist, not too wet, and not too wet, and not waterlogged.

Celery leaf peony, scientific name: flower buttercup, the leaves are like celery, the flowers are like peonies, hence the name "celery leaf peony".

The reasons for the yellowing of buttercup leaves are as follows;

Natural aging. Injuries to the base of the petiole cause the leaves to turn yellow.

Lack of fat Frostbite or sunburn.

Poor ventilation leads to the growth of miscellaneous bacteria in the soil.

Countermeasures and suggestions for the above possible reasons:

If you don't think it's aesthetically pleasing, you can cut off the yellowed leaves, pay attention to the treatment of the wound, and use carbendazim to apply to the injured area.

Apply thin nitrogen fertilizer.

Pay attention to the air temperature and humidity, the temperature is below 5 at night and the balcony temperature is over 35 during the day, it is recommended to move back indoors.

Pay attention to loose soil, use pots with leaky holes, use toothpicks, and poke the soil appropriately, which is conducive to soil ventilation.

Resources.

My celery leaf peony has been repotted for a while, what's going on.

First: a natural phenomenon, plants also have metabolism;

Second, the roots and trunks of the plant are injured by external forces;

Third: insufficient nutrients, long-term malnutrition;

Fourthly, the winter is not properly protected from the cold, so that the plants are frostbitten;

Fifth: Lack of proper shade in summer, especially after too strong sunlight at noon;

Sixth: poor air circulation, resulting in obstruction of plant respiration, bacterial breeding, and invasion of plants.

If the leaves are yellowed due to natural phenomena, you can ignore them or cut them off; Try not to hurt the plant pants when breeding plants, if there is a wound including the cut should be carefully cared for, you can use disinfectants and the like to spray the wound to prevent infection;

Although it does not have much demand for fertilizer, it should not be left unfertilized for a long time, especially during the flowering and growth periods, and sufficient nutrients must be maintained;

In winter, if the temperature has dropped to 5 degrees, then move indoors for the winter; In summer, when the temperature exceeds 35 degrees, it should be placed in a cool place, but no matter where it is placed for breeding, it is necessary to ensure good ventilation; If the soil is too wet, you can use a bamboo skewer to insert it into the soil, which can effectively relieve it, but try to stay away from the roots to prevent rooting.

Sunburn, frost damage, lack of nutrients, and stagnant water can cause celery peony yellow leaves.

Although celery peony likes light, it is limited to astigmatism and is afraid of direct light. If it is kept in direct light for a long time during the maintenance period, it is easy to be sunburned, resulting in yellow leaves. It is necessary to shade the light in time, or move to a cool and well-ventilated environment, especially pay attention to the strong light in summer.

Celery peony prefers a warm environment and has very poor cold tolerance. If it is in a low temperature environment for a long time during the maintenance period, such as the temperature is lower than 0, it is easy to be frostbitten, resulting in yellow leaves. It is necessary to move to a warm place as soon as possible and take temperature control measures, preferably to stabilize the temperature above 10, so that it can safely overwinter.

The demand for nutrients during the growth period of celery peony is relatively large, if it is not topdressed for a long time, the soil is poor, and the nutrients cannot be absorbed, and yellow leaves will also occur. If this situation is caused, it is necessary to top dressing as soon as possible, and it is best to apply diluted liquid fertilizer, which is absorbed quickly and can also avoid fertilizer damage.

The celery peony prefers humid environments, but it is afraid of waterlogging. If the watering is too frequent or the amount of water is too large during the maintenance period, it is easy to accumulate water, which will cause the roots to be watery, resulting in yellow water. In this case, it is necessary to drain the stagnant water as soon as possible, strengthen ventilation, and loosen the surface of the soil frequently, so that the water can evaporate as soon as possible and the plants recover as soon as possible.

If the water accumulation is severe, it is best to depot it and check whether the root system is rotten.
