What s wrong with the dry peony leaves? Is it a seasonal problem or a disease?

By July, August and February and March, thank you!

The yellow leaves of the four seasons peony may be caused by lack of water or damage to the root system.

1. Improper watering.

Too little watering, the plant lacks water, and the old leaves begin to turn yellow from the bottom up. If there is a long period of water shortage, the leaves of the whole plant will be dark yellow, and even die.

Solution: Watering should be timely, appropriate, and according to the condition of the potting soil. Smaller pots should be watered frequently, and larger pots should be watered after the soil surface has dried. It is advisable to water thoroughly, and the potting soil should not accumulate water.

Second, rotten roots. Peony flowers are fleshy roots, the potting soil is uncomfortable, and if the pot is not changed in time, bacterial infection will cause rotten roots. It is difficult to detect abnormalities in the above-ground parts at the beginning, but the absorption capacity of the roots gradually decreases, and the lower leaves slowly turn yellow and gradually spread to the whole plant.

Solution: Change the pot every year to check the growth of the roots, and prune the roots in time. Pay attention to proportionality when watering to avoid stagnant water and rotten roots. Piccagen can be used appropriately to make the root system robust.

The defoliation period of peony flowers is from late October to early November, and the leaves of peony gradually turn yellow, forming a layer and falling off.

Let's take a look at the various growth and development periods of peonies:

First, the peony germination period.

In the middle of February every year, when the temperature reaches about 4, the scale buds of the peony will absorb water and swell, and then gradually bloom, and the tips of the buds will be exposed.

Second, the peony budding period.

At the end of February and the beginning of March, when the temperature reaches about 7, the tips of the scale buds of the peony are cracked, and the top and half buds of the buds can be seen.

3. Peony budding stage.

In late March, the current branch of peony is about 10 cm long, and the leaf petiole is close to the new branch and stands upright, and the flower bud diameter is generally about 10 cm.

Fourth, the peony leaf development period.

This period is in early April, and the branches of peonies are about 15 cm long.

Fifth, peony translucent period.

About 10 days after the peony spreads its leaves, its buds have matured and gradually completed the coloring process, commonly known as the "round bud stage".

Sixth, peony flowering period.

The flowering period of peony is in mid to late April, the flower buds bloom, the flowering period of different varieties is 6-10 days, and the whole flowering period can reach nearly a month.

7. Peony leaf growth period.

When the peony flowers wither in early May, the leaves enter the rapid growth period, the growth rate accelerates, and they become larger and thicker.

8. Growth and differentiation period of scale buds.

Peonies begin to sprout scale buds in the leaf axils, and the leaf primordium is fully formed from late July to late August.

9. Flower bud differentiation stage.

In the middle of August, the flower bud differentiation accelerated, and from mid-September to mid-October, the flower bud differentiation of general varieties was basically completed, and the bud body was full.

10. Peony defoliation period.

From late October to early November, the leaves of the peony gradually turn yellow, forming a layer and falling off.

Characteristics of peony growth and development period.

After the end of the defoliation period, the peony will enter a relatively dormant period, and the surface of the plant has stopped growing, but there are still physiological activities inside.

After the peony flower fails, some dead leaves will appear because the nutrition cannot keep up, generally in May and June; In addition, the dead leaves of peonies in autumn and winter are relatively normal. In other seasons, the dead leaves of peonies are generally caused by malnutrition or pests and diseases.

Peonies generally dry their leaves naturally in late autumn.

Depending on the local climate, leaves generally fall from the beginning of September to the end of September.

Peony seeds are harvested in time for maturity in early August and sown immediately. If the seeds are sown too late, the seeds should not germinate in the spring. Peonies are sown for 5-6 years before flowering, so this method is generally only used when cultivating new varieties.

Divide the large peony that has grown for more than five years and dig it out, put it in a cool place and dry it for 2-3 days, and when the roots become soft, divide it into a group of 2-3 branches and plant it in the nursery.

Notes:

Peony disease is common brown spot disease, the prevention and control method is to start after flowering every year, spray Bordeaux liquid or Tuo Wan head cloth dip once every half month, and a number of fungus spirits. Cut off the diseased leaves and burn them in time before winter, and spray stone sulfur mixture before germination in spring.

Peony insect pests mainly blow cotton scale insects, white insect body attached to the branches and leaf backs in summer and autumn, can be sprayed with 500 times fluoroacetamide or 1000 times liquid oxidation dimethoate solution or painted with stone sulfur mixture after winter.

Abnormal! This is a disease of peonies! You may not notice it after the flowering, but it is easy to have this problem after flowering, and the temperature will rise in July, when the temperature rises, and the high temperature causes brown spots on the leaves, and finally the leaves will wither and wither!

It will be after 9 months that the spread of the disease will stop! By that time I guess it's damn good, you squirt something on it!

Go to the flower market and ask if there's any liquid sprayed for your situation! Bordeaux liquid, carbendazim and the like!

1. The dry leaves of peony may be caused by too much light, although they like light, they are afraid of strong light. If it is not shaded in summer, it will burn the leaves and cause dryness.

2. It should be moved to a semi-shaded place as soon as possible, and more ventilation should be provided. It may also be caused by too much watering, which hinders the respiration of the root system. It is necessary to stop water treatment, ventilate frequently, and evaporate water. In addition, it is possible that the amount of fertilizer applied is too large, which will cause fertilizer damage. It should be rinsed with clean water to drain the fertilizer.

Peony is the king of flowers and is sought after by many people. Therefore, many flower lovers like to maintain a few pots at home, but there are often various problems in maintenance. Recently, flower lovers have encountered the problem of dead leaves.

Let's go with the gardener uncle to understand the causes and solutions of the dried leaves of peony flowers. 1.Exposure to bright light.

If the place where the peony is pickled in the summer is directly irradiated with strong light, then the leaves of the peony are dried up, and then the dried leaves will fall. Solution: If the dry leaves of the peony flowers are caused by sun exposure, it is recommended to shade the peony before summer, so that the peony will not dry up.

2.Improper planting time peony has more roots, which can fully absorb nutrients in the soil. If the peony flower is planted too much, the soil will harden or freeze, which will reduce the growth of the peony root system.

When the peony sprouts the following spring, the root system cannot fully absorb the nutrients, and once it is hot summer, the peony leaves will dry up. Solution: It is generally recommended to plant peonies in autumn, because after planting in autumn, peony plants can have enough time to grow, so that the peony root system grows strong.

As long as you take good measures to keep warm in winter, before the arrival of summer, then the root system will grow well and you will not be afraid of not being able to absorb nutrients. 3. The soil is not suitable. In the summer, you can know whether the soil for planting peonies is suitable.

If the soil planted is compacted or alkaline, it will affect the growth of peonies. If the soil is not suitable, the roots will not absorb enough nutrients, which will cause the peony leaves to become dehydrated, dry and fall off. Workaround:

It is not recommended to grow peonies on saline or sandy soil. It is recommended to plant ordinary garden soil. Then, just add an appropriate amount of coarse sand, and at the same time increase an appropriate amount of organic fertilizer to keep the peony with sufficient nutrients.

If the soil is not suitable, it is advisable to try changing it. 4.Too much fertilizationIf there is too much water and fertilizer, it will cause the roots to be difficult to bear, causing the roots to rot, which will also act on the leaves.

If the amount of fertilizer is relatively large, stop fertilizing, increase the amount of watering, wash away the residual fertilizer in the soil, or change the soil.

After the peony flower leaves wither, put the flowers in a shady corner, water them every ten days or half a month, and do not be too diligent, otherwise it will lead to root rot. Change the soil once in autumn, pay attention to increasing fertilizer, according to the watering method of seeing dry and wet, keep the water in the potting soil sufficient, put it in the direct sun, you can grow the base and produce new leaves.

How to solve the withered leaves of peony flowers.

1. Reduce watering

Peonies are succulent root plants that prefer semi-arid mud shed soils, and if there is too much moisture, it will cause root rot and the leaves will wilt. Therefore, the amount of watering should be reduced, preferably once every ten days or half a month, not too often. If it rains continuously, it should be drained in time, and the roots must not be allowed to accumulate water.

2. Change the soil and top dressing

The leaves of peony flowers generally begin to wither in July and August, at this time it needs to be changed again, potting soil can be a mixture of sand and cake fertilizer, or a 1:1:1 mixed culture soil with rotten manure, garden soil and coarse sand.

The nutrients in the pot are limited, and timely topdressing is required to ensure the normal development of peony flowers.

3. Maintenance experience

Peony flowers love sunlight and are hardy, and when they are cultivated at home, they must be placed in a place where they can be exposed to direct sunlight and have good ventilation. The nutrients of peony flowers are mainly based on base fertilizer, so the base fertilizer should be sufficient, and the fertilizer applied in the later stage must be rotten and not too thick, otherwise it will lead to moldy and rotten fleshy roots.

Through our introduction, I believe you have a deeper understanding of what to do when the peony leaves wither.

Hello dear, normal, it is one of the normal phenomena for peony leaves to dry up in summer. Peony is a deciduous tree plant, and in the hot weather in summer, the peony leaves will be affected by a certain degree of dehydration, evaporation, and blind burial, resulting in dry leaves. At this time, the peony may be dormant or in a state of reduced growth, which is in response to the high summer heat and arid environment.

While it is normal for leaves to dry up to some extent, there are a few things to be aware of:1Maintain adequate water sources**

Even if the leaves look dry, you need to make sure the roots are well hydrated**. Water regularly and keep the soil moist, but avoid overwatering that can lead to root rot. 2.

Protection from the sun: Avoid direct exposure of peonies to strong sunlight, especially in the middle of the day and afternoon. Potted plants can be moved or sunscreen screens can be used to provide suitable shade.

3.Provide proper ventilation: Make sure there is good air circulation in the area where the peonies are planted to lower the temperature and reduce leaf dehydration.

4.Pay attention to fertilization and pest control: In summer, peonies are in the dormant period, and the appropriate amount of fertilization should be required to avoid over-fertilization.

At the same time, pay attention to inspect the leaves and take necessary measures to control pests and diseases. If the leaves of the peony continue to dry up in other seasons or in drought conditions, it may be caused by lack of water, nutrients, disease or other environmental problems, which require further inspection and grinding. It is recommended to take appropriate measures to maintain the healthy growth of peonies according to the specific situation.

Peonies are more delicate, and they can't live when their flowers and leaves wilt.

The cause analysis or the root or the light.

The light is too strong, or the disease is a pest. Genus.

Cultivation of peony flowers.

Peony flowers like cold and dislike heat, should be dry and afraid of moisture, and can withstand low temperatures of -30. Shade-loving, loose, fertile, well-drained neutral soil or sandy soil is required, and heavy soil or low temperature planting is avoided. Flowering period is from April to May.

Soil: Soil quality: Peony is suitable for loose and fertile soil with deep soil layer. The soil drainage capacity must be good. Potted plants can be cultivated in general soil.

Soil: neutral or neutral slightly alkaline soil.

Watering: "Peonies should be dry rather than wet. "Peony is a deep-rooted fleshy root, afraid of long-term waterlogging, usually watering should not be too much, to be appropriately dry.

Water 2 times before planting. Fill with water once before winter to ensure its safe wintering. After the beginning of spring, water according to the dry and wet conditions of the soil, but do not overwater.

Fertilization: The cultivation of peony base fertilizer must be sufficient. The base fertilizer can be compost, cake manure or manure.

It is usually better to apply fertilizer three times a year, that is, spray once a half month before flowering, with fertilizer water based on phosphate fertilizer and strong flowers; Compound fertilizer is applied once half a month after flowering; Apply compost once before winter to ensure flowering the next year.

When potting, the bottom of the pot can be spread with coarse sand or small stones 3-5 cm thick to facilitate drainage. The potting soil should be mixed with yellow sand soil and cake fertilizer, or with fully decomposed manure, garden soil, and coarse sand at 1:1:

1 ratio of mixed culture soil. The soil should be filled so that the root system is stretched and cannot be curled; After covering the soil, it should be compacted by hand so that the root system is in close contact with the soil, so that it is easy to survive. After potting, water once and put the seedlings in the semi-shade.

After being transferred to normal management, it can be placed in a sunny place to ensure that it has sufficient sunlight exposure. During the growth period, the soil should be loosened frequently, and compound fertilizer should be applied every half a month or so. Newly potted peonies can not be fertilized, especially avoid thick fertilizer, otherwise the fleshy roots will be moldy and rotten to death.

After half a year, you can gradually apply some thin fertilizer, such as rotten chicken manure or bean water, etc., and the ratio of fertilizer to water is 20%-30%. Newly potted peonies may not produce good flowers in the first year, but after 1-2 years of cultivation, they can bloom year after year. Peony blooms in mid to late April a year, and liquid fertilizer can be applied 1-2 times before flowering; Half a month after flowering, apply liquid fertilizer 1-2 times; Futian can use sesame paste residue (about 40-50 grams per pot) to apply dry fertilizer once to facilitate flower bud differentiation.

Peony is a fleshy root, slightly drought tolerant, most afraid of stagnant water, so whether the watering is proper is a key issue in the success or failure of potted peonies. Generally, the peony that comes out of the room in early spring should be fertilized once, and then watered thoroughly, and the soil should be loosened after the water is slightly dried. In the future, watering should be carried out in a timely and appropriate amount according to the weather and potting soil conditions, and the potting soil should be kept moist frequently, which is conducive to the growth and flowering of peonies.

Reasonable watering should be dry and wet, not suitable for large watering, to prevent water accumulation in the pot, so as not to rot roots and leaves.

When the peony blooms, it can be covered by a shed or temporarily placed indoors, avoiding direct sunlight, which can prolong the flowering period, and the top bud of the main branch is a leaf bud, which should be removed, so as not to grow and affect flowering. In order to make the peony bloom brightly, the dihydrogen phosphate solution available during the flowering period is sprayed 2-3 times. After the peony flowers are gone, it is necessary to carry out a plastic pruning, cut off the residual flowers and flower stalks in time, do not let the seeds set, and retain the 1-2 outer buds of the stem, so that the plant can grow vigorously and ensure that the next year blooms.
