temperatures are included in the common sense of green plant maintenance?

Cold-tolerant flowers: can tolerate the low temperature of about minus 2 degrees. Such as winter jasmine, begonia, elm leaf plum, Hosta, clove, day lily, wisteria, etc. 2。

semi-cold-tolerant flowers: can tolerate the low temperature of about minus 5 degrees, such as tulip, rose, chrysanthemum, pomegranate, Shaoyao, etc. 3。 Flowers that are not cold-tolerant: such as Asparagus, Eupatorium odoratum, Hewanglan, alternifolia, poinsettia, hibiscus, calla lily, Prynne and succulents.

the important position of water in flower cultivation 1. Pay attention to water quality: according to the amount of magnesium salt and calcium, it is divided into hard water and soft water, and soft water is better for watering flowers.

rainwater is the best (zui), followed by river water and pond water. Remember: do not use dishwashing water or water with washing powder, and tap water should be dried for one day before use, so that CL2 in the water can be fully volatilized. 2。

pay attention to the water temperature: don't quench or heat suddenly. 3。

water quantity: it is more in spring, so it should be watered in the afternoon; Summer foot should be watered early and late; Less watering in autumn; In winter, water it once every few days according to the dryness and wetness of the basin. 4。

attention should be paid to watering: according to different seasons, different weather and plant preferences. In a word, before watering, analyze the water shortage directly before watering.

2. How to make potted wisteria blossom year after year

Wisteria has a well-developed root system. Although it likes sunshine, it is also resistant to shade. It is also cold-resistant, drought-resistant, and does not choose soil and soil. It is easy to manage for outdoor planters.

However, the maintenance and management of wisteria as a potted plant is not easy, so there is a saying that "potted wisteria does not bloom". If we can do the following work well and manage it carefully, potted wisteria will still flourish and bloom year after year.

(1) Cut off the residual flowers in time to prevent pod growth. Wisteria blooms from the end of April to the beginning of May, and bears thick pods, up to 2 cm long.

a small potted wisteria can bear more than 1 pods, which consumes a lot of nutrients and is difficult to blossom in the next year. To this end, the sooner you cut off the residual flowers, the better.

(2) Cut off the elongated branches and vines in time to prevent them from climbing around other things. Potted wisteria must be surrounded by nothing to climb and form a small shrub.

However, in the hot rainy season, even if there is nothing to climb around, sometimes you will stick out your branches and look around. When this phenomenon is found, the long vines should be cut off immediately to avoid consuming nutrients.

otherwise, once you climb around something else, it will grow rapidly. It has been proved that potted wisteria that climbs around other things will not bloom in the next year, or even for several years.

(3) The overwintering temperature should not be too high. If potted wisteria plants overwinter indoors, the room temperature will be too high, and wisteria plants will not be fully dormant, which will consume stored nutrients and affect the next year's flowering. Wisteria is cold-resistant and can overwinter outdoors, even if the temperature drops to ? Below c, it will not be frozen.

(4) Control fertilization. Potted wisteria has little soil, and the nutrients in the soil are far from enough for its growth and flowering. Failure to replenish fertilizer in time will affect flowering. However, without controlled fertilization, it is easy to make branches grow in vain and affect flowering.

Generally, dilute cake fertilizer water can be slightly applied before flowering and long-acting phosphate fertilizer can be slightly applied after flowering to promote flower bud differentiation. In winter and summer, no fertilization is needed.

3. How to cultivate potted wisteria bonsai Cultivation methods and precautions

In order to make wisteria blossom year after year, the following aspects need to be done well.

1. If potted wisteria overwinters indoors, the room temperature should not be too high, otherwise wisteria will not be fully dormant and will consume too much stored nutrients, which will affect the flowering in the coming year. Wisteria is cold-resistant, and the temperature below degrees outdoors will not be frozen.

2. Appropriate fertilization. Fertilization deficiency of potted wisteria or excessive fertilization will affect flowering. Generally, diluted cake fertilizer water is applied before flowering and long-acting phosphate fertilizer is applied after flowering to promote flower bud differentiation. No more fertilization in winter and summer.

3. The tendrils of potted wisteria will stretch and twine to consume nutrients. If this situation is found, it should be cut off immediately, otherwise the twined tendrils will grow rapidly and the plants will not bloom.

4. wisteria blooms from the end of April to the beginning of May. After flowering, it bears thick pods, up to 3 cm long. One plant can bear multiple pods, which requires a lot of nutrients, and it is difficult to bloom again in the next year. Therefore, it is necessary to cut off the residual flowers in time to prevent pod growth.

wisteria does not bloom for the following reasons:

① The variety is not good. Under the same growth conditions, some wisteria flowers a lot, some flowers a little, and some don't. I used to have several potted wisteria plants, most of which bloomed a lot every year, but one pot was difficult to bloom, sometimes with few flowers. After three years, it was grafted and replaced with a variety that was easy to bloom. Now it blooms a lot every year, which fully shows the diversity of varieties.

② cultivation techniques. A. Poor management and malnutrition will lead to few flowers; B. Pruning is too heavy every year, and a large number of long branches are produced, which is not easy to form flower buds; C. Pests and diseases have seriously damaged the tree, making it unable to grow normally, let alone bloom; D. Excessive vegetative growth and crazy growth of wisteria branches inhibit reproductive growth, and it is also difficult to form flower buds.

countermeasures

a. varieties with more flowers must be selected. if it is determined that it is not due to cultivation techniques, they should be grafted in time and replaced with excellent varieties that are easy to bloom.

B. If wisteria does not bloom due to malnutrition, pests and diseases, management should be strengthened at ordinary times to ensure the needs of vegetative growth and cultivate ideal tree shape and tree potential;

C, reasonable pruning is carried out according to the growth potential, strong pruning is light, and weak pruning is the opposite;

D. For those with excessive vegetative growth, we can control vegetative growth and promote reproductive growth by applying less nitrogen fertilizer and more phosphorus and potassium fertilizer during the growth period, withholding water, and not cutting or lightly cutting 1-2-year-old seedlings, so as to achieve the goal of more flowers and better flowers.

4. can wisteria be potted? knowledge

wisteria can be potted

when turning over the pot, prune the tree trunk once, cut off the rattan stems, and thinly prune the vines that are too dense on the stems, and handle the transition point between the top branches and the stems. You can properly lift the roots when you go to the basin, and put them in a sunny place after you go to the basin.

wisteria likes fertilizer, and thin and decomposed organic fertilizer should be applied frequently during the growing period, and liquid fertilizer should be applied once a month except in flowering period. Always water the basin to keep the soil moist. Pay attention to water control after autumn to prevent the autumn shoots from sprouting in vain, the trees are too vigorous, and there are too many branches and leaves to bloom easily.

The modeling adopts a combination of bud picking, coring and pruning and climbing. After germination in spring, leave 2? 3 bud, when the new shoot is 15 cm long, pick the core to promote the formation of flower branches, bloom at the top of the new shoot, and the flowers are blooming. During the dormant period, the branches should be cut short, and the distribution structure of branches should be adjusted to keep the shape beautiful. Usually, we should trim the long branches, too dense branches and too long hanging branches to concentrate nutrients on the flowers.

5. why potted wisteria is difficult to blossom

potted wisteria is difficult to blossom, mainly because the maintenance and management are not in place.

First, cut off the residual flowers in time to prevent pods from consuming nutrients. Second, cut off the excessively long stems and vines in time to prevent them from winding on other objects. Any potted wisteria that winds on other objects will not bloom, even for several years, so it is better to develop a shrub shape.

Third, the room temperature should not be too high during wintering, otherwise it will easily lead to insufficient dormancy, consume nutrients in the body and affect the flowering in the coming year. Generally, it is better to overwinter at room temperature of about ℃. Fourth, it is necessary to control the types and dosage of fertilization. Generally, thin fertilizer water can be slightly applied before flowering, and late-acting phosphate fertilizer, such as multi-element slow-release compound fertilizer granules, can be applied after flowering to promote flower bud differentiation, and no fertilization can be applied in winter and summer.

6. Planting method of potted wisteria I want to know: 1. Potted wisteria can be exposed to the sun

Planting wisteria should choose a dry place with deep soil layer, fertile soil and good drainage, which is easy to rot roots if it is too wet.

Generally, the planting time is from autumn defoliation to spring germination. The main roots of wisteria are thick and long, and there are few lateral roots, so it is not resistant to transplanting. Therefore, when transplanting, the plants should be re-cut with or without soil balls, and the planting holes should be applied with organic fertilizer as base fertilizer. After planting, they should be watered.

For larger plants, a sturdy and durable trellis should be set before planting, and after planting, the thick branches should be tied to the trellis to make them climb along the trellis. The daily management of wisteria is simple, and proper water and fertilizer management can be carried out according to the water and fertilizer status of soil.

Pruning wisteria is an important work in management, and the pruning time should be in the dormant period. When pruning, the branches can be evenly distributed by removing the density and keeping the sparse and manual traction. In order to make flowers flourish, we should also prune them reasonably according to their budding habits. Because wisteria has strong branching ability, flower buds are planted in the axils of annual branches, and the tops of growing branches are easy to dry up. Therefore, we should retract the new branches of the year, cut off 1/3-1/2, and cut off the bases of weak branches and dead branches.

In order to make potted wisteria blossom brightly every year, besides intensive cultivation of tubules, several tips should be mastered. (1) Selecting mature seedlings for potted plants.

wisteria has a straight root system, with a long taproot and few lateral roots. When transplanting in a pot, it should take a long taproot and put it in a pot. Cultivate with sandy loam rich in humus, and put a small amount of broken hoof pieces as base fertilizer.

The flowerpot should be placed in a ventilated shade for one week, and then placed in a well-lit place. (2) Flowers bloom in early March, and less watering and fertilization are needed when flowering, thus prolonging the flowering period.

cut off the residual flowers immediately, so as not to make them pod-bearing, so as to prevent nutrient consumption and affect the quantity and quality of flowering in the next year. (3) Cut the elongated branches and vines in time to prevent them from climbing to the surrounding objects, so as to prevent nutrient loss and insufficient nutrients when they bloom in the next year, and the flowers will not bloom or bloom.

(4) During daily maintenance, water should be withheld and fertilizer should be controlled properly to prevent overgrowth of branches and vines, and long-acting phosphorus and potassium fertilizer should be used as the main topdressing. (5) When overwintering, it should be placed at a low temperature of about ℃ to keep the pot soil slightly wet and make the plants fully dormant. In the next year, spring flowers and leaves will flourish and the flowers will be colorful.

7. What are the cultivation methods and precautions of wisteria

Wisteria belongs to Leguminosae, which is a deciduous climbing and winding vine with beautiful purple or deep purple flowers. Common cultivated varieties are: one-year-old rattan, Xi Xiangteng, Ben Hongwangteng, Ben Baiwangteng, Three-foot rattan, double-petal wisteria, rich-flowered wisteria and so on.

wisteria has deep main roots and shallow lateral roots, so it is not resistant to transplanting. Fast growth and long life. Strong winding ability, it has strangulation effect on other plants. Buds appear in March and flowers bloom in April, with 2 to 8 butterfly flowers on each axis.

Wisteria should be planted in a dry place with deep soil layer, fertile soil and good drainage, which is easy to rot roots if it is too wet. The planting time is generally from autumn defoliation to spring germination. The main roots of wisteria are thick and long, and there are few lateral roots, so it is not resistant to transplanting. Therefore, when transplanting, the plants should be re-cut with or without soil balls, and the planting holes should be applied with organic fertilizer as base fertilizer. After planting, they should be watered. For larger plants, a sturdy and durable scaffolding should be set before planting, and after planting, the thick branches should be tied to the scaffolding to make them climb along the scaffolding. The daily management of wisteria is simple, and proper water and fertilizer management can be carried out according to the water and fertilizer status of soil.

Pruning wisteria is an important work in management, and the pruning time should be in the dormant period. When pruning, the branches can be evenly distributed by removing the density and keeping the sparse and manual traction. In order to make flowers flourish, we should also prune them reasonably according to their budding habits. Because wisteria has strong branching ability, flower buds are planted in the axils of annual branches, and the tops of growing branches are easy to dry up. Therefore, we should retract the new branches of the year, cut off 1/3-1/2, and cut off the bases of weak branches and dead branches.

wisteria is easy to propagate, and it can be planted, cut, layered, divided into plants and grafted. Seeding and cutting are mainly used, but cutting is the most widely used method because it takes a long time to cultivate seedlings.

cuttage propagation cuttings generally adopt hard cuttings. Before the branches germinate in the middle and late March, select 1-2 year-old stout branches, cut them into cuttings about 15cm long, and insert them into the seedbed prepared in advance. The cutting depth is 2/3 of the cutting length. Spraying water after transplanting, strengthening maintenance, keeping the seedbed moist, the survival rate is very high, the plant height can reach 2~5cm in that year, and it can be out of the nursery two years later.

Rooting is the use of adventitious buds easily produced on wisteria roots. Roots with a thickness of .5~2.cm were dug in the middle and late March, and cuttings with a length of 1~12cm were cut and inserted into the seedbed, and the cutting depth was kept at the same level with the ground. Other management measures are the same as branch cutting.

the sowing and breeding is carried out in March. The seeds were harvested in November, and the pods were peeled off, dried and bagged for storage. Soak the seeds in hot water before sowing. When the temperature of boiling water drops to about 3℃, take out the seeds and wash them in cold water for a while, then keep them moist and pile them up for a day and night before sowing. Or store the seeds in wet sand and soak them in clear water for 1-2 days before sowing.

layering, plant division and grafting were all carried out in the middle and late March.

Here are a few propagation methods:

1. Sowing propagation: Sow the seeds in autumn, or artificially pollinate them at the time of flowering, so as to promote pod setting. When the pods are ripe, collect them in dry storage (sand storage is better) and sow them in the next spring.

2. Cutting propagation In early spring in the south, after thawing in the soil in the north, take one or two-year-old shoots, cut them into 1-15 cm segments, and insert them directly or obliquely.

3. The layering method takes biennial branches after defoliation, peels off part of the bark and presses them into the soil.

4. Young plants from rhizosphere were cut by tillering method and transplanted in winter and spring.

5. Grafting method uses one or two-year-old branches to graft at the root and move out after survival.

To plant wisteria well, we should pay attention to the following issues:

First, illumination: wisteria likes sunshine, but is slightly shade-tolerant. Because wisteria is a big vine, in order to make it grow well, it is generally cultivated with certain scaffolding. Wisteria also has shorter species and varieties that can be used as potted plants or bonsai.

second, temperature: wisteria has strong adaptability, heat resistance and cold resistance, and is cultivated from south to north in China. So in Guangdong, the temperature can adapt to wisteria all year round.

thirdly, watering: wisteria has deep taproots, so it has strong drought resistance, but it likes moist soil, but it can't be soaked in water, otherwise it will rot.

fourth, fertilization: wisteria can basically meet the needs by applying compound fertilizer 2-3 times a year.

fifth, soil: the main root of wisteria is long, so the planting place needs deep soil layer. Wisteria is barren, but fertile soil is more conducive to growth. Wisteria also has strong adaptability to soil pH value.

sixth, location: besides the sunny and deep soil mentioned above, the wisteria planting location needs to be sheltered from the wind.

Seventh, propagation: Wisteria can be propagated by cutting, layering, sowing, grafting and tillering.

Wisteria has strong straight roots, so it is necessary to dig as many lateral roots as possible when transplanting and bring land. More than planting in early spring, before planting, scaffolding must be set up, and thick branches should be tied to the scaffolding to climb along the scaffolding. Because wisteria has a long life and thick leaves, the scaffolding materials must be solid and durable. When young trees are first planted, the branches can't form flower buds, and peanut buds will appear later. If it doesn't bloom after several years of planting, it is because the tree is too strong and has too many branches and leaves, and the tree is weak and it is difficult to accumulate nutrients. The former adopts partial root cutting and thinning of branches and leaves, while the latter can blossom by adding fertilizer. Fertilizer should be appropriately applied with more potassium fertilizer. Topdressing is usually 2~3 times during the growth period. After flowering, 5~6 buds can be cut off from the middle branches and the weak branches can be cut off to promote the formation of flower buds.

In potted wisteria, in addition to selecting shorter species and varieties, pruning and coring should be strengthened to control the plants from being too large. If bonsai is cultivated, shaping and pruning need to be strengthened, and if necessary, old piles can be used to plant pots and graft fine varieties.
