5 tips for growing peony

1.Best planting time: The best planting time for peony is mid-september to late 10.

2.The best growing soil: Peony cultivation soil texture loose, fertile, neutral alkali.

3.Growth humidity requirements: Peony watering to both keep the soil moist, but not too wet, not water for the principle.

4.Optimal growth temperature: Peony cold-resistant, not resistant to high temperature. In Eastern and central China, the flower buds began to expand gradually when the temperature reached 4 °C. SUITABLE TEMPERATURE: 16 ~ 20 °C, less than 16 °C do not bloom. When the temperature is high in summer, the plant is semi-dormant.

5.The Best Growth Light: Peony like the Sun, but do not like the Sun. When the ground is planted, need to choose a higher position facing east, potted should be placed in the sunny east balcony, such as the south balcony or roof platform, the west should try to shade.

The most common types of tree peony flowers

Since ancient times, peony is considered as a symbol of wealth, peony flowers large, beautiful color, colorful, very beautiful, pleasing to the eye.

Peony experts and scholars and related researchers have proposed flower type classification, namely Peony Flower type includes single-petal type, Lotus type, chrysanthemum type, rose type, melaleuca type, hanging type, gold ring type, crown type, hydrangea type, tower type these several kinds.

The petals of a single peony flower have more than ten, two to three rounds, broad shape. The results are stronger. This kind of flower type represents to include opium purple, Garnet Red, Feng Danbai to wait.

Lotus-type peony flowers have many petals, there are more than 20, there are four to five rounds, its orderly arrangement, broad shape, with individual stamens and pistil stigma petalization of the situation. The representatives of this type of flowers include lotus-like, Jinyunhong, Yubanbai and so on.

The flower shape of moutan peony decreases gradually from the outside to the inside, its arrangement is neat and clear, its petals have six rounds or more, but its bearing ability is poor.

The rose type peony flower is similar to the Chrysanthemum type in shape and petals, but its fruiting ability is not high.

The lower petal of Melaleuca type peony is more, the stamen is normal, the lower petal is less, the shape is flat and the stamen quantity is small. Its representatives include fat red, longevity red and so on.

Hanging peony flower part of the stamens into long and slender petals, petals arranged in an irregular, strong, such flower type on behalf of including ladies, Jiaohong, Xiane and so on.

There is a circle of normal stamens between the Middle Petal and the outer petal of the gold-ring type peony flower.

The name of the crownlike peony flower resembles a crown because of its dense and towering petals. IRREGULAR SHAPE, occasional petalization and degeneration, on behalf of a blue field jade, Hu Hong, Yao Huang and so on.

Hydrangea peony petals crowded uplift, showing a ball-shaped, no seed-bearing capacity, on behalf of varieties such as green, Green Incense Ball

Why is it so hard for a novice to grow tree peonies

One is the growth of peony do not understand, two is to hire workers in order to fast, save energy. Planting too shallow will lead to bad root, root and stem joint hidden buds not buried in the soil, the winter wind easily blow dry the root and stem of this piece of water, seedlings easy to dry up or even die, the next spring is not easy to produce more branches.

The root of the soil washed clean can be seen at the root-stem junction hidden bud, some obvious, some not obvious.

2. tree Peonies are less watered

Especially in arid areas, the seedlings do not grow well in the coming year, even when the sun is strong at noon, the stems and leaves wilt, and the stems and leaves stand up again in the morning and evening, mostly because of too little or no fixed root water when planting. There are arid areas where the winter monsoon is relatively strong and there is little snow, and winter water must be poured when the land is frozen in winter.

Drought tolerance of tree peony means that tree peony can survive and grow for at least one year before drought tolerance, because the tree peony has produced enough fine root, and its fleshy root developed more robust, stored more nutrients and water. Fear of waterlogging refers to the accumulation of water can not exceed 3 days, the day of the big water, 24 hours of water can disappear is no problem.

3. Do not understand the importance of planting time and management

The southern soil moisture is big, the winter temperature is high, the rooting cycle is long, the root growth quantity is big. The planting time can be later than October. When planting, the new roots are more suitable for southern soil, and the measures of planting and root-cutting can avoid the occurrence of root rot to some extent.

Northern Autumn temperature fall faster, planting time as early as possible, so that the peony root growth time will be longer, the growth of the root will increase, the next year will be vigorous seedling growth. The colder the area, the earlier the planting, the end of the heat can be planted. Peony planting in the north, generally according to the size of the seedlings to take measures, flat stubble, do not give up branches, cut off the branches, let the new growth of branches to grow, new long branches grow better, more able to adapt to the cold windy climate in the north. Of course, flat stubble is for the series of seedlings, for transplant with soil ball semi-formed or formed peony, it needs to be a certain amount of pruning, and do not need flat stubble.

The method of tree peony seed seedling

1. Picking seeds, generally in early August, peony seeds mature one after another. The seeds are initially white, nearly Brown at maturity, and black at maturity. When the fruit was picked crab yellow, put indoor cool damp place, make the seeds in the shell after ripening, and often turn, so as not to heat, until most of the fruit cracking, seed emergence. Do not dry in the sun, or the seeds often do not germinate.

2. Seed treatment, the seeds out, should be sowed immediately, sowing late, the next year does not germinate, or even wait until the third year of Spring to Germinate. If it is too late to sow, wet sand burial method can be used, planting sand ratio of 2:8. This about 30 days, bud tip slightly exposed, and then sowing in the field, the following spring is still normal germination. Direct sowing or quickening germination in sand, the seeds should be soaked in 50 °C warm water for a day and night to make the seed coat soft, absorbent and expand, easy to germinate and germinate.

3. PAEONIA SUFFRUTICOSA is not very high demand for soil, choose permeability of sandy soil or loam soil, soil adaptability is more extensive, do not viscosity too much soil can be

4, Management, in order to prevent soil moisture evaporation, can shade in the seedbed, it is best not too much water, because watering more soil will harden. After entering November, sunshade can be removed, before the frost with Straw, grain grass or leaves covered seedbed to prevent moisture preservation, until the next year in February to remove the cover, start

watering.

Peony common 8 kinds of pests and diseases

Peony Growth and development process, if properly managed can live for decades or even centuries. If the growing condition is poor, the tree peony is often damaged by diseases and insect pests and the influence of bad environment, resulting in many spots and incomplete leaves, weak growth of branches, dry root system, rot or development deformity, thus greatly reducing the ornamental value,

gray mold

Botrytis CINEREA is one of the most important diseases in the world. The disease can occur in the growing season of tree peony.

Symptoms

The disease endangers the stems, leaves and flowers of peony. When the stem appears Brown spots, rot, seedling withering and lodging. Infected leaves produce irregular water spots, leaf tip and leaf edge spots more, brown spots, but also purple-brown, sometimes with irregular ring pattern, wet weather department gray mold. Petiole and leaf stem disease spot for more long, dark brown, a little depression, disease department easy to break. Infected Flower Buds Brown, dry, Brown petals, rot. Under moist conditions, gray mould layer can be formed at the site of the disease. The disease is a fungal disease.

Low temperature and humidity are the main conditions of the disease. In spring, the temperature is lower and the continuous rain will aggravate the disease of the seedlings. The disease often occurs after the flowering period of the host, 6 ~ 7 months, more nitrogen fertilizer, is conducive to the disease.

Control method

1. Combined with yard cleaning, timely removal of diseased leaves and plants, and focus on burning.

2. In case of disease during growing season, the following medicament can be used for spray control: 1% lime equivalent bordeaux solution, 70% thiophanate-methyl 1000 times solution, 65% ZNZN 500 times solution, or 50% chloronitramine 1000 times solution. Spray every 10 to 15 days, 2 to 3 times in a row.

3. The density of planting should be moderate, the plant should be drained in time after rain, the plant should not be moistened from the base, the rotation should be carried out in the serious disease area, and the seedling should be planted without disease, the seedling can be disinfected by soaking for 1015 minutes in 65% ZINCON 300 times solution.

Brown spot disease

Brown spot disease, also known as the red spot disease, the disease is widespread, serious harm, disease rate of leaves can reach 89.3% , often cause early blight, affect the growth of peony.

Symptoms

Brown leaf spot mainly damages the leaves of Tree Peony, but also infects branches, flower organs, seed and other parts. In the early stage of the disease, there were large round or irregular spots on the leaves, which were Brown on both sides. When the disease was serious, the spots converged and caused the leaves to be withered and twisted, and dark green mould layer appeared on the back of the spots under moist conditions The spot on the flower organ is Brown spot, and the edge of the petal is scorched when the disease is serious. The spot on the flower organ is Brown spot, and the edge of the petal is scorched when the disease is serious. The disease is caused by fungi.

The disease is more serious in warm and rainy conditions, more pathogens, more nitrogen fertilizer, higher planting density and poor ventilation and light transmission. The high temperature rainy season is the peak period of disease.

Control method

1. To reduce the source of infection, Autumn thoroughly remove the debris on the ground, spray 50% CARBENDAZIM 600 times liquid or 3 baume degree sulfur mixture before germination of plants in early spring to kill the bacteria.

2. Starting from early May, 50% MANCOZEB 500-fold solution or 75% CHLOROTHALONIL 800-fold solution was sprayed once every 15 days for 3 ~ 4 Consecutive Times.

3. Planting density is moderate, apply organic fertilizer and compound fertilizer.

4. Clean the field in winter, then spray the stem with 7 ~ 10 times lime-sulfur mixture.

Anthrax

ANTHRACNOSE is a common disease of tree peony in China. The United States, Japan and other countries have also reported. Anthracnose often makes peony leaf withered spots, twisted stems, young shoots dead.

Symptoms

Anthracnose of Tree Peony damages leaves, stems, flower organs and other parts of Tree Peony. In late April, round purple-brown spots appeared on the leaf surface, petiole and stem, and gradually expanded to nearly round spots. The size of the spots varied from 4 mm to 25 mm in diameter, and the spots on the leaf margin were semi-elliptic The expansion of the lesion was semi-elliptic due to the influence of the main vein.

The black spot reveals color, the middle part of the late period is gray-white, the spot edge is red-brown. There are many black spots on the spots. In the humid condition, there are red-brown sticky clusters on the spots. This is the characteristic of anthracnose. The lesions dehiscence and perforation in the late stage. On stem and Petiole of disease spot is lozenge mostly, a bit sunken, long 3 ~ 6 millimeter, red-brown; later period is gray-brown, edge is red-brown. The diseased stems are twisted and break when they are seriously ill. The young stems become diseased and die off quickly. Bud Scales and petal damage can cause flower bud death and Corolla deformity. The disease is a fungal disease.

The onset of the disease usually begins in late April, and the peak period is from August to September. High temperature, more rain, more dew, plant cluster closed easily induced diseases.

Control method

1. Cut off the victim and burn it.

2. At the initial stage of the disease (may-june) , 70% of furosemide 500 times, or 1% of lime equivalent bordeaux solution, or 65% of thymosin 500 times, 10-15 days, a total of 2-3 times.

3. Keep the plants well ventilated to avoid high temperature and humidity.

Purple Feather Disease

It belongs to fungus disease. Mainly from the soil and spread with the root when planting separately.

Symptoms

The disease occurs at the base of the trunk near the ground and at the root. The young roots or the neck of the roots are covered with purple or white cotton-like Hyphae, which appear yellow-brown at first and black later. After the disease, peony old roots rot, new roots do not grow, thin branches, germination late, leaves become small, from the bottom up withered and yellow wither, branches in death.

The disease can occur at any time, not limited to plum festival, but the early summer rainy season more common. Raw Land, low-lying wet land or improper fertilization (the use of raw fertilizer, heavy fertilizer) , the most susceptible to disease.

Prevention and Control Methods 1. Select high dry terrain, good drainage of loose soil, fertilizer to fully mature, avoid direct contact with the fertilizer roots.

2. Separately, can use 0.1% of copper sulfate solution immersion root 3 hours, or half an hour with lime water immersion, and then rinse with clear water replant.

3. If the disease is found, the rotten parts should be removed immediately or scraped off with a knife, and then disinfected with 4-5 Baume's lime-sulphur mixture or sulphur.

4. At the beginning of the disease, 50% ZINCON 1000 times solution can be used to irrigate the roots, 500 ~ 1000 ML per plant

5. Rotation is carried out every three to four years.

5. Rust

Rust fungus is a host, the intermediate host is Paeonia Lactiflora, anemones, strychnine, pine and so on, so the peony nurseries near the plant can not be planted.

Symptoms

The leaves are fading Green, and the leaves are backed by piles of yellow boulders. In the late growth period, columnar hairs grow on the diseased leaves.

Control method

1. Remove and destroy the infected plant.

2. Planting should be high and open, with good drainage.

3. Before the onset of the same amount of Bordeaux liquid 160 times dilution, or spread 400 times of Zineb.

4. After the onset of stone sulfur mixture, dixie sodium, Triadimefon and other prevention and treatment.

White Silk Disease

SCLEROTIUM ROLFSII mainly occurred in the stem base near the ground. After the disease, the CORTEX of the stem base and root rotted, the water and nutrient transportation of the plant was cut off, the leaves became yellow and withered, and the whole plant died.

Symptoms

White Hyphae were formed on the surface of the root neck at the initial stage of the disease, and were covered with Silk Hyphae when the disease was serious.

Control method

1. First, root neck lesions were thoroughly scraped off with a knife, and the wound was disinfected with 1% copper sulfate solution. At the same time, the soil around the infected plant was opened up, and 70% pentachloronitrobenzene was mixed with the new soil in a ratio of 1:100, and evenly scattered in the soil around the diseased root.

2. The soil around the roots was irrigated with 50% ZNZN 400-fold solution.

Stem Rot

In the stem near the ground waterlogged spots occur, gradually expand rot, appear white woolly. Small initial markings on leaves, gradually enlarging to large gray-white and Hazel Markings, white spongy in wet weather. When the bud is injured, there are dark brown spots, and then rot.

Control method

1. Extirpate the diseased plants and disinfect the soil.

2. Healthy disease-free plants should not be planted in diseased areas.

3. Equal Dose Bordeaux Mixture.

Root Rot

Damage the root, so that the root black rot, serious when the whole plant death.

The method of prevention and control is to dig out the diseased plants and burn them, and spread some sulfur powder or lime in the planting holes to disinfect the soil

Several points for attention in planting peony

If you like to plant peony, you should know that peony is a kind of flower plant. The requirements of growing environment are very strict. As long as you have mastered some small skills to maintain peony flowers, so in this season also can transplant peony flower Oh! Because peony flowers like to grow in a cool, well-drained place, so generally in the spring when transplanting peony flowers, will be more difficult and in the autumn, peony it's roots grow more fat, grow white and tender fine roots. So when transplanting peony flowers, as long as the root system can make peony flowers become fat and strong, then it will be very easy to survive. The following is to hand over to everybody this right in this peony flower 8 big skills, as long as completes these steps, can guarantee the peony flower to be beautiful

1. Prepare for transplanting

Because in April is the flower bud differentiation season of peony, it is easy to damage the root system of transplanted peony at this time, resulting in insufficient nutrient supply, destroying the nutrient balance in the plant, affecting the flower bud differentiation and flowering Or is not the State of growth, or even excessive damage to the root system, but also very easy to affect the plant root rot death phenomenon.

2. Seedling selection

If you want to peony really grow well, then must choose those growth fat strong, full peony seedlings. If it is random selection of some poor branching ability, and the root system is not developed varieties, then basically in the spring is difficult to survive. Therefore, it is best to choose those varieties with more developed roots to transplant.

3. Seedling requirements

It is very important to keep the earth ball when digging the peony flowers. Only by keeping the earth ball on the root can the water supply of the root be extended and the survival rate of the plant be increased It can also avoid over-drying the roots during the production process, reduce the evaporation of water and promote the growth of plants.

4. Home Planting

When the peony seedlings arrive at their destination at the first time, they should be planted in time. At this time, the straw wrapped in the roots or other packing bags can be removed and the peony flowers together with the earth balls can be placed in the dug pits If planting can not be done in the first place, put the peony plant in a cool, well-ventilated place and spray it with water to keep it alive.

5. Prune

In order to ensure an optimal growth state of peony flowers, we must learn to prune some of the flower branches, ensure the normal distribution of nutrients in the plant, cut off some of the new leaf buds and flower buds, and Prune them according to the normal maintenance Only one bud is needed for each flower branch.


6. Fat Water Management

After transplanting the peony well again, we must first water it thoroughly, and then the second watering time should be half a month later, and then basically is the advent of the rainy season, at this time also need to give Paeonia suffruticosa drainage measures To prevent the accumulation of water leading to root rot. In the vigorous growth period of peony, phosphorus and potassium fertilizer can be applied 2 ~ 3 months after taking pot, which can promote the bud opening of peony and prolong the flowering period.

7. Shade and cool down

Because the peony flowers like to grow in a cool and ventilated place, so to the summer, it is necessary to give it shading cooling treatment, only reduce the transpiration of leaves, can extend the peony flowering period. In the course of daily maintenance, it is best to keep the peony flowers under the tree, or in a cool place, remember not to put under the sun for exposure.


8. Prevent pests and diseases

In August and September, it is a period of frequent occurrence of peony blossom mildew. At this time, we must remember to give peony flowers, carry out pest prevention and management measures, and recommend the use of diluted carbendazim solution Every 10 days to its watering, can play an effective pest prevention measures.

Characteristics of Paeonia rockii

Paeonia rockii gets its name from a distinct patch of color at the base of its petals, although wild species are found in Gansu, Shaanxi, Henan and Hubei But the cultivated varieties are mainly concentrated in Wei River, Tao River and the vast areas along the ancient Silk Road in the Daxia River valley in Gansu Province. The cultivated areas are mainly in the provinces of Sichuan, Gansu, Qinghai, Shaanxi and Ningxia (autonomous regions) Therefore also known as the Gansu Peony or northwest peony. In Gansu Province, the cultivation of Paeonia Rockii not only can be traced back to the Tang Dynasty, but also has been cultivated in more than 60% of counties and cities.

Morphological characteristics
Deciduous SHRUB. Stem up to 2 m tall; branches short and thick. Leaves usually twice trifoliate, occasionally 3-foliolate near Shoot Apex; Terminal Leaflets broadly ovate, 7-8 cm long, 5.5-7 cm wide, 3-lobed to middle, lobes unlobed or 2-3-lobed, surface green, glabrous, abaxially Pale Green, sometimes white-powdery, petiolules 1.2-3 cm long, sparsely pubescent or subglabrous along veins; lateral leaflets narrowly ovate or oblong-ovate, 4.5-6.5 cm long, 2.5-4 cm wide, unequal 2-to 3-lobed or undivided, subsessile; Petiole 5-11 cm long, and Leaf axis are glabrous. Flowers Solitary; apex of branches, 10-17 cm in Diam. ; Pedicel 4-6 cm; bracts 5, Oblong, unequal in size; sepals 5, Green, broadly ovate, unequal in size; Petals 5, or double, rose, red-purple, pink-white, usually highly variable, obovate, 5-8 cm long, 4.2-6 cm wide, apex irregularly undulate; Stamens 1-1.7 cm long, filaments purplish red, pink, upper white, Ca. 1.3 cm long, anthers oblong, 4 mm long; Lathe faceplate leathery, cup-shaped, purplish red Apex with several sharp teeth or Lobes, completely enveloping carpels, dehiscing when carpels are mature; carpels 5, more sparse, densely pilose. Something something oblong, densely covered with Yellowish Brown bristles. Flowering May; fruiting June.
The difference with Peony: Petal Inside Face Base Ministry has deep Purple Patch. Leaves bipinnate to triplex, leaflets undivided, 2-4-lobed. The Flower is big, the petal is white.

Range of distribution
Distributed in northern Sichuan, southern Gansu, southern Shaanxi (Taibai mountains) . Wild species are found in undergrowth shrubs on hillsides at elevations of 1100-2800 M. In Gansu, Qinghai and other places have cultivation.
Growth Characteristics

Paeonia ROCKII is one of the best cultivars in China. It is very different from Central Plain Paeonia Rockii, such as Heze, Shandong and Luoyang.
Gansu Paeonia Rockii, named for the large Purple Patches and Purple Erythema at the base of its petals, is native to the remnant forests in the Alpine region of Gansu Province. A small number of surviving plants still grow in the mountains at altitudes of 1100-3200 meters. The lowest winter temperatures in these areas are generally-30 °C and in some areas-38 °C, so the species is naturally resistant to cold.
Gansu Paeonia Rockii almost all show the basic characteristics of PAEONIA ROCKII: Plant Tall, Shuxinqiang, long branch spacing, high growth, some varieties of the same year branches can be as long as 70 cm. The plant height is more than 1 meter (some varieties are as high as 3 meters) , the number of small leaves is more than 15, the leaves are smaller (anti-transpiration) , the leaf back is hairy, all varieties have obvious large purple spot and purple red spot at the base of the petals. Most of the anthers and ovaries are yellow-white or white, and some of the anthers are purplish red. The native species of Central Plain Peony are derived from the female parent of the native species from Anhui and other places, and the hybrids of Yangshan Peony from Mount Song County in Central Plain and Dwarf Peony from Jishan in southern Shanxi are the male parent The basic characteristics of Dwarf Tree Peony are: The plant is shorter (usually less than one meter) , the tree is weaker, the internode spacing of branches is shorter, the annual growth is smaller. The Basal number of leaflets is 9(part is 11) , the terminal leaflets are 3-lobed, the other leaflets are mostly deeply notched, the leaf blade is larger, the flower center (including stigma, disk, filament) are mostly purple-red. Because these areas are relatively low altitude, mild climate, cold climate adaptation is not strong, to resist the low temperature of minus 25 °C.

How to protect tree peonies in winter

1. Peony must be moved indoors after the beginning of winter. It is better to keep the room temperature at 0 degrees. Put the peony in a sunny place to ensure the peony can be exposed to the sun. Move Out of the house around March next year and place in a sunny leeward area, fertilize and water management.

2. If the tree peony plants are more and more dense, the potted tree peony can also be buried in the soil. The exposed branches should be protected by grass thatch to keep the tree peony warm and safe for the winter The coming of the next spring can be removed grass thatch, the peony into the sunny place, a few more times of fertilizing.

3. The flowers and seedlings will lose their leaves in autumn and winter, when you have to cut off the remaining branches, the dense branches and the branches with diseases and insect pests. This will not only ensure ventilation and light transmission between the plants It also concentrates the nutrients in the pot onto the remaining plants.

The management of Peony in winter is mainly the control of temperature. The indoor temperature can not be too high, which will affect the normal development of peony, nor can the temperature be too low. Whether the peony will blossom in the coming year will have a great influence Winter peonies do not need to be watered much during the dormant period.

After the peony enters the winter dormancy period, the nutrients begin to return to the roots. It is better to irrigate once before the soil freezes, that is, in winter. Watering the frozen water well can promote the decomposition of the Basal Fertilizer, and is beneficial to the new root occurrence and the flower bud differentiation in winter and spring.
