What is the reason why the ground planted peony has been blooming for several years and suddenly doe

Why not bloom.

The seedlings that have just been bought from the market, because the root system is few and short, do not store enough nutrients, can not meet the nutrients needed for flowering, or in other words, the plant's own nutrition is only enough to maintain the normal growth of the root system, and it is difficult to bloom that year.

In fact, it is the poor ventilation of the plant, which leads to poor growth. Improper maintenance in the home,. Watering too much potted area water, not fertilizing for a long time, infected with pests and diseases, rotten roots ......All of these reasons can affect the flowering of the plant.

What to do if it doesn't bloom.

In order to make the potted peony pregnancy buds bloom, the following needs to be done:

First, if the plants you buy back are new seedlings, what you need to do is to be patient, and the roots will bloom after 2 to 3 years.

Second, strengthen maintenance, put the plants in a sunny and ventilated place, and the potting soil should be fertile and loose to avoid water accumulation.

Third, pay attention to replenishing nutrients in a timely manner, not just before and after flowering. For example, during the dormant period in winter, fertilizer should be applied once, choose a water-soluble fertilizer with nitrogen and phosphorus combination or soak the fertilizer with soybean cake crumbs. In early spring, when the leaves are growing, fertilizer should be applied 1 or 2 times, so as to ensure that the pregnant buds of the plant have enough nutrients for flowering.

In recent years, in terms of peonies, many flower friends have been deceived, either not flowering, even if they bloom, they will pat their thighs, learn more here, and be less fooled.

Ground peonies do not bloom when they are planted, and there are usually several reasons why they do not bloom: Improper root splitting time when peony is planted. Peony is mostly propagated by split roots, and it is better to do it in autumn after the aboveground parts have withered (mid-September to mid-October).

Because the growth characteristics of peony are that they will germinate earlier in spring, and after germination, they will grow rapidly, and flower buds will appear soon. If the roots are separated in spring, some roots will be damaged during operation, which will affect the absorption of nutrients by the plant, so that the plant cannot provide the nutrients needed for flower bud formation, so it will not bloom. And because of the split roots, it can also cause poor plant growth and even no flowering for many years to come.

Therefore, the flower proverb has the saying that "the peony on the vernal equinox does not bloom when it is old". In late autumn, new roots can occur before the year, and they will grow and bloom smoothly the next year. Peony is planted too deeply.

When planting peonies, the thickness of the covering soil should not exceed 5 cm in the root system, so that new shoots can grow from the root system. If the planting is too deep, the buds should not germinate in the soil, and even if the seedlings emerge, the growth and development are not vigorous, thus affecting the flowering. Therefore, when the planting is too deep, it should be replanted.

The correct method of peony planting is: digging a hole 35 cm deep, holding the flower seedlings when planting the peony, so that the roots are stretched and placed in the hole, when filling the soil to half of the depth of the hole, shake and jacquard seedlings with your hands, so that the root system and the soil are tightly combined. When the flower seedlings are raised, the buds should be level with the soil surface.

In this way, the watered soil sinks, which is just in line with the ideal peony planting depth. Improper maintenance of peony during cultivation. After many years of root separation, the plant will senescence, and if it is not re-planted, it will affect flowering because of weak growth.

Peony likes fertilizer, and sufficient basal fertilizer should be applied around the plant in autumn for the next year's germination and flowering; After flowering, it is necessary to fertilize in time to restore the growth of the plant and maintain vigorous growth. Otherwise, the plant grows thin, which is not good for flowering. In addition, peony prefers a moist and well-drained environment, especially in the spring before germination, avoid the soil is too dry, otherwise it is not conducive to flowering.

It's true, the spring equinox peony, when it is old, does not bloom, that is, the wrong time of planting, will cause the peony to not bloom.

When are peony flowers planted.

1. Peony is mainly propagated by the method of dividing, which is also said when to divide the plant, then when to plant. There is such an old saying about the branches, which is called "peony on the vernal equinox, and it will not bloom when it is old", that is, it must not be planted in the spring.

2. Then the best time for planting branches, that is, from early September to late October, at this time, the ground temperature is higher than the temperature, which is conducive to the healing of peony wounds and the germination of new roots.

Second, how to plant peony flowers.

1. Branching: When planting, dig out the whole peony with a shovel, observe the condition of the peony root system, shovel along the natural texture of the peony root system with a spade, ensure that each bush has at least 2-5 buds, and then apply Cuim Genbido on the wound (note that it must be diluted), and put it in a cool and ventilated place to dry.

2. Planting: After the wound is thoroughly dried, according to the original planting depth, the fleshy root system after the division is re-buried in the soil, the soil is compacted, and the root water is poured once after planting, and then you don't have to care, and when it is warm in the spring of the next year, the peony can send out new sprouts and bloom in late spring and early summer!

3. Attention. In addition to dividing peonies, peony can also be propagated by sowing, usually peony seeds mature in August, and when the seeds are ripe, they are sown with picking, or they are dried in the shade and stored in the sand, and they are sown in mid to late September. However, sowing and propagating peonies is easy to atavistic and double-petaled to single petals.

1. Planting time.

Peonies can be grown from the roots of peonies, and the best time to plant them is in autumn, which is from the end of August to the end of September. Planting should not be too early or too late, or it will not affect the growth, and the autumn is just the right climate for planting, and it can heal and grow new roots, and wait until the next spring to grow quickly.

Second, the root preparation.

Prepare the tubers first, dig them out in September-October, when the climate is cool, then shake off the soil, dry and cut into roots with small shoots. If you can't plant it in a pot immediately, you can put it next to it to dry the incision and apply sulfur powder to sterilize. <>

3. Prepare the soil.

The soil in the planting area is leveled and the planting site is selected. If it is planted in pots, it is necessary to configure loose and breathable, nutritious and fertile sandy soil in advance, and apply base fertilizer in advance.

Fourth, carry out planting.

Arrange the soil, plant the roots with small shoots, and then cover with soil and gently press it to cover about 10 cm thick soil layer. To make the small buds exposed, plant them well and water them thoroughly, and keep them in a well-ventilated place. <>

5. Post-management.

After planting, it is still necessary to pay attention to good management and maintenance, keep it under astigmatism, keep it moist with regular watering, maintain a suitable temperature, and weed regularly.

Peony seeds cannot bloom in the first year. Peony is generally planted in August and September in autumn, and will enter the dormant period after the end of autumn, at this time it will not continue to grow, and if it is properly maintained, it generally blooms in the spring of the following year.

Peony flowers bloom in early to mid-May, with rich flower colors, large flower types, and short flowering periods, which can only last for 8-10 days and can last for about 15 days.

The main factors influencing flowering phenology.

1) Temperature: In the same area, the morning and evening of peony flowering are closely related to the temperature change in spring. Temperature can affect the entire flowering process. The flowering period can vary from 4 to 5 days to 10 to 20 days.

2) Water and rainfall: water and rainfall have little impact on the flowering period, fully irrigated before flowering or rainfall, which helps the peony to bloom, the flowers are huge and the flower color is gorgeous; However, if there is heavy rainfall, the flowers will be damaged and will fall early. If the soil moisture content is low before flowering, the flowers will become smaller, the flower color will not be bright, and the flowering period will be shortened.

3) Altitude separation: Altitude can affect changes in temperature, light and humidity, thereby affecting the flowering period. In general, flowering is delayed as the altitude increases.

For example, the peony in Luoyang ended its flowering period on May 14, and the peony was just translucent on Baiyun Mountain in Manxian County, near it. The peony in Pengzhou City, Sichuan Province bears fruit in flowering period, and the nearby Danjing Mountain is nearly in full bloom. It can be used to use the different sea aid of the cultivation site to highly intersect, and the court has a long ornamental period.

4) Light: Light is often accompanied by temperature and has a significant impact on plant growth and flowering. Insufficient light before flowering will affect the flower color, making it not strong enough, and strong light during flowering, accompanied by increased temperature, will shorten the flowering period or burn the flower.

Therefore, building an awning during the flowering period will prolong the flowering period of the peony.

It has to do with the maintenance method.

Proper maintenance methods:

1. Sufficient light.

Peony is a sun-loving plant, after it sprouts, it should be exposed to sufficient light, so at this time it should be maintained in a well-lit environment, so that it can fully photosynthesize, so that it can grow quickly, be careful not to maintain it in a dark environment for a long time, and it can not be exposed to the sun.

2. Reasonable watering.

After the peony sprouts, it also needs to be watered reasonably, and its growth needs to have sufficient water, so it is necessary to observe the dryness and humidity of the soil every day, and find that the soil is dry to immediately replenish its water, but it should be noted that it should not be watered too much, otherwise the root system of the peony is easy to rot.

3. Apply thin fertilizer frequently.

Peony needs a lot of nutrients to grow after germination, so at this time we also need to apply thin fertilizer to it regularly, you can choose potassium dihydrogen phosphate in fertile leaves to meet the nutrients required for its growth, otherwise if you do not fertilize for a long time, resulting in the plant does not have sufficient nutrients, then it is prone to poor growth.

4. Ventilation and temperature control.

To maintain the budding peony, it is also necessary to do a good job of ventilation and temperature control measures for it, at this time, it should be placed in a well-ventilated place, so that it can absorb fresh air, and the temperature control is more suitable at about 20, which is most conducive to its vigorous growth, otherwise the temperature is not suitable, and the plant is easy to grow slowly.

Most of them are due to the wrong time of dividing.

Timely planting of peony is conducive to the healing of root wounds, and can germinate new roots, enhance the ability of cold and drought tolerance, and lay the foundation for the germination and growth of the following year. Do not divide the plants too early, so as not to occur in autumn, which will affect the growth and development of the next year; It is also not advisable to divide the plants too late, when the ground temperature can no longer meet the needs of the peony roots, so that the new plant grows poorly in the following year; If it is planted late in spring, the buds germinate in the soil, because the spring temperature is gradually higher, the air temperature is small, the transpiration is large, the root system is injured after the branching, and can not absorb water and nutrients normally, resulting in the growth of broken plants is very weak, and even dies, so China's agricultural proverb has "the spring equinox peony, to the old does not bloom".

The peony dividing period is generally earlier than the peony, and the agricultural proverb of Heze "peony in July, peony in August (referring to the lunar month)", which means that in Heze, peony can be divided from the end of August until the end of September (summer to autumn equinox). Yangzhou divides from late September to early November. After three or four years of growth, the seedlings can be divided again.

If you don't distinguish between years, the root system will decay, the plant growth will be weakened, and the flowering will be poor.

Mature peonies generally bloom after April every year. If the planting soil is not good, the sunlight is insufficient, and the nutrients are not enough, there will be a phenomenon of not flowering for many years. If it is a potted peony, it is necessary to conceive buds and bloom:

It should be placed outdoors in a sunny and ventilated place, and the potting soil should be loose and fertile to avoid stagnant water.

It is necessary to pay attention to the addition of nutrients, such as in the dormant period of winter, it should be applied to the base fertilizer of the Dandan measuring rod and the super stream for 1 time, and nitrogen can be used. Phosphorus-bound organic fertilizer can also be added to soybean cake crumbs and bone meal mixed and then added. When growing branches and leaves in early spring, nitrogen is applied 1-2 times.

Phosphorus-bound top dressing. In this way, the plant will be able to sprout and bloom.

Summary. We need to put the peony flower in a sunny and ventilated place to maintain a sufficient light environment, so as to promote its better absorption of nutrients, and the branches and leaves can bloom vigorously. Therefore, try to give as much light as possible to make it bloom more vigorously; Generally, at the beginning of cultivation, a small amount of cake fertilizer needs to be added as the base fertilizer to improve the yield of soil fertility, and the growth period should be vigorous, and additional fertilizer should be applied.

Phosphorus fertilizer and potassium fertilizer were applied once one month before flowering, which was more conducive to the vigorous flowering of peony. If the soil hardens severely, we need to replace the potting soil in time and press 2:2 with humus, garden soil, cinder or river sand

The ratio of 1 is mixed to keep the soil conducive to drainage, in addition, the flower friends of the north, pay attention to the pH value of the soil, you can pour in an appropriate amount of ferrous sulfite solution to adjust.

We need to put the peony flower in a sunny and ventilated place to maintain a sufficient light environment, so as to promote its better absorption of nutrients, and the branches and leaves can bloom vigorously. Therefore, it is necessary to give as much light as possible to make its Kairu bloom more vigorously; Generally, at the beginning of cultivation, a small amount of cake fertilizer needs to be added as the base fertilizer to improve the yield of soil fertility, and the growth period should be vigorous, and additional fertilizer should be applied. Phosphorus fertilizer and potassium fertilizer were applied once one month before flowering, which was more conducive to the vigorous flowering of peony.

If the soil hardens severely, we need to replace the potting soil in time and mix it with humus, garden soil, cinder or river sand in a ratio of 2:2:1 to keep the soil conducive to drainage.

If peony flowers want to bloom beautifully, they must do a good job of fertilization. Peony flowers are very fond of fertilizing. If you don't fertilize for a long time, the peony won't bloom.

When peonies bloom in spring, you can use some decomposed organic fertilizer and sufficient phosphorus and potassium fertilizers, which can not only meet the needs of growth, but also prepare for flowering. After flowering, it is not only necessary to cut off the residual flowers in time, but also to apply some organic fertilizer and compound fertilizer to restore growth. If the peony sprouts too much in spring, it will cause excessive consumption of nutrients and will also cause the phenomenon of not flowering.

Therefore, it is recommended that we leave some thick branches in the spring.
