The dry and yellow leaves of peony can not escape these six reasons.

21, peony leaves dry and yellow, can not escape these six reasons!

This is an excerpt from the original column "Peony Culture" written by the Blue Devil.

The leaves of peony flowers are often withered and yellowed in the process of culture. So why did this happen? How should we deal with it? Today, the blue demon will specifically introduce the causes and countermeasures of the dry and yellow leaves of the peony leaves.

Six reasons for dry yellow leaves of peony:

1. Overwatering

Peony flowers like dry and wet, the most avoid stagnant water, if the basin soil is too wet for a long time, it will cause poor root breathing and yellow leaves.

The over-watered yellow leaves are mainly characterized by no obvious change in the old leaves and yellowing in the new leaves. If it is found that the new leaves of peony turn yellow and the potted soil is relatively wet, it should be considered that it is caused by too much watering.

Coping methods:

Loosen the soil in time, strengthen ventilation, control watering, later watering dry and wet, it is expected to prevent the basin soil from stagnant water.

2. Dry yellow leaves

Although peony likes to be dry, too much drought can also cause peony yellow leaves. The dry yellow leaves are mainly yellow leaves from bottom to top, the old leaves are yellow first, and the new leaves are normal.

Response:

When the peony pot soil is too dry, it should be watered in time to replenish water.

3. Excessive alkali in soil

When mixing soil on peony flowers, we said that peony can not grow in too alkaline soil, so rice chaff ash is used instead of plant ash, because plant ash is too alkaline.

If the alkalinity of the basin soil is too large, the peony will grow badly and appear yellow leaves, which is mainly represented by the chlorosis between the leaf veins, and the main veins remain green, showing the phenomenon of yellow and green alternately. After serious, the leaf veins gradually lose green, and then the whole leaf turns white, the leaf margin is scorched, and the leaves fall off.

Coping methods

When the peony basin soil is too alkaline, acid fertilizer should be applied in time to neutralize the alkalinity of the soil.

4. Improper fertilization

Clear peony, turbid peony. Peony fertilization is more exquisite, generally do not use liquid fertilizer, can not use raw fertilizer thick fertilizer, if improper fertilization will cause peony leaves yellowing, leaf tip dry. Sometimes it will show that the new leaves are thick, shiny and uneven.

Coping methods

When the scorched yellow leaves appeared in the peony after fertilization, it showed that the fertilizer was damaged, and a large amount of water was used to irrigate the roots to dilute the concentration of inorganic salts in the soil.

If the new leaves are thick and uneven, you need to stop fertilizing for a period of time and wait for them to recover naturally.

5. Malnutrition

Many people dare not apply fertilizer as soon as they hear the "clear peony", which leads to the phenomenon of malnutrition due to insufficient fertilizer, showing yellow leaves. When malnourished, yellow leaves first occur in new leaves.

Coping methods

When the fertilizer is insufficient, the yellow leaves should be topdressing in time, which can be buried with fermented organic fertilizer or foliar fertilizer with low concentration of water-soluble fertilizer.

6. Rotten root

The above five kinds of yellow leaves are relatively easy to solve, but if they are rotten roots, they will be more troublesome.

The rotten root of the peony may be due to stagnant water in the basin soil, or it may be due to root rot. In short, after the rotten root, the peony will turn yellow and fall off from the lower leaves and gradually develop upward.

Coping methods

Slight root rot can be solved by filling roots with fungicides such as carbendazim and mancozeb, and then controlling water.

If the rotten root is more serious, the peony should be dug out, trimmed off the rotten root, soaked in mancozeb solution, and then planted with new soil.

Some flower friends will find that newly planted peonies are prone to leaf curling. Why? Tomorrow will continue to decompose for you, welcome to continue to follow.
