Maintenance and management of goose palm vine

Goose palm vine, also known as duck foot wood, is an evergreen woody vine. Its branches and leaves are soft and elegant. It is often used for potted plants in halls, porches, venues, etc., and is often used as garden color hedges or shapes in the south. The cultivation of goose palm vine is not difficult, so let me introduce to you the main points of its cultivation.

Goose palm vine

Goose palm rattan prefers high temperature, humid and semi-overcast environment. The suitable temperature for growth is 20-3090, the overwintering temperature is more than 5 ℃, and the leaves below 0 ℃ are easy to fall off. Be resistant to shade and avoid bright light. The soil has strong drought resistance, and the loam or sandy loam with loose and fertile soil and good drainage is the best.

Pot soil can be mixed with U such as rotten leaf soil and garden soil. Change the basin before the new buds germinate every spring, get rid of part of the old soil, add new culture soil and apply less LIFP- base fertilizer. The old plant that is too large is re-cut and renewed, that is, most of the branches are removed and part of the root is cut off. Put it back on the pot. During the growing period, the soil should be kept moist, combined with foliar spraying in summer to maintain high air humidity. Under proper shading, the plant grows well in a well-ventilated semi-shady environment. If the soil is too wet or early, or if it is placed in too dark for a long time, it will cause leaves to fall off. The peak growing season is from March to September every year, and the rotten organic fertilizer can be applied 1 or 2 times a month. Varieties with yellow and white markings will blur their markings if the light is too weak or nitrogen fertilizer is applied. Under the low temperature in winter, the water should be properly controlled and placed in a sunny place indoors.

Management methods of flowers in July the maintenance and management of flowers in July the management methods of flowers in July mainly include the following:

I. Flower culture

1. Sowing seeds

The grass flowers that can be sown in July are: melon leaf chrysanthemum, spring of the four seasons, kale, bluebells and so on. When sowing, we should pay attention to moisturizing, shading and increasing ventilation and light transmission.

In July, mature fruits such as plum, hairy peach, mountain peach and elm leaf plum can be picked, washed and sown, or the washed drupe can be stored in wet sand to the crack before sowing. Wintersweet seeds can be sowed as they are picked, and the seeds removed from the fruit sac can also be dried and stored for sowing in the following spring, which will not affect its germination rate.

two。 Cuttage

The species of grass flowers suitable for cutting culture in July are: Scutellaria barbata, begonia, colourful leaf grass, cold water flower, string red, marigold, peacock grass, thousand-day red, geranium, Dutch chrysanthemum, chrysanthemum, umbrella grass, wall-climbing tiger, coral flower, pepper grass, unicorn leaf, fire charcoal mother, ground root, green pineapple and so on.

The woody flower species suitable for cutting culture in July are: red-backed cinnamon, southern bamboos, poinsettia, tiger prickly plum, hypericum, golden plum, sea immortal, eight immortal flowers, brocade, hemp leaf hydrangea, snow spray, Ruixiang, gardenia, fragrance, Tiannu, triangular plum, Milan, jasmine, pearl orchid, goose palm wood, ten great efforts, pomegranate, crape myrtle, hibiscus, fiery thorn, Zhu banana, Fusang, June snow, smile, coral tree, mulberry. Rubber tree, Qionghua, Tianmu Qionghua, yellow poplar, Yuanhua fruit, purple magnolia, sweet-scented osmanthus, rhododendron, camellia, tea plum, dragon claw willow, golden willow and so on. Guding flower can also be cut with scales.

In addition, some flowers and trees can be raised by water insertion in July. They are: gardenia, oleander, rose, jasmine, pearl orchid, fig, pomegranate, inverted golden bell, crape myrtle, hibiscus and so on. To cultivate flowers and trees by water cutting, one is to have a foam plastic board with a thickness of 1 cm to 2 cm, which is used as a cutting fixing material after perforation; the other is to keep the water quality of the cutting water clean and put a few pieces of charcoal into it for anticorrosion.

3. Grafting

Annual mountain peach and hairy peach seedlings can be used as rootstocks, budding to cultivate green peach, Shouxing peach, red leaf peach, plum blossom, elm leaf plum, red leaf plum, beautiful plum, etc.; cuttings of wild rose, pink rose and "ten sisters" are used as rootstocks, budding cultured varieties rose, cut rose and rose; potted Magnolia and Magnolia seedlings are used as rootstocks, and Magnolia magnolia and Magnolia magnolia seedlings are used as rootstocks The 2-year-old seedlings of Chimonanthus praecox can be used as rootstocks, and the seedlings of 2-year-old Chimonanthus chinensis can also be used as rootstocks. Grafting is carried out at a distance of 3 cm to 4 cm above the ground, and whether it survives or not can be judged after 7 to 10 days. "Purple Butterfly" and "Jade Butterfly" in rhododendron are used as rootstocks to cultivate Belgian rhododendron or rhododendron by split or abdominal grafting. Cherry seedlings were used as rootstocks, excellent varieties of cherry blossoms were cultured by budding, current-year seed seedlings of bauhinia, Hubei begonia or weeping begonia and begonia flowers were used as rootstocks, T-shaped buds were grafted to cultivate excellent varieties of begonia. Acer maple seedlings were used as rootstocks and bagged grafting to cultivate red maple, feather maple and other seedlings.

4. Pressing strip

The species of flowers and trees that can be cultivated by pressing in July are: Milan (high pressure), wax plum, honeysuckle, eight immortals, Lingxiao, Qionghua, oleander, brocade, broom, sweet-scented osmanthus, gardenia, purple magnolia, jasmine, Zhulan, rattan this month rose, welcome spring and so on.

5. Ramet

II. Seed harvesting and transplanting

1. Harvest seeds

The seeds of grass flowers that can be harvested in July are: hollyhock, sunflower, morning glory, summer grass, petunia, fluke, Digitalis, snake chrysanthemum, sweet pea, daisy, delphinium, pansy, pine chrysanthemum and so on.

The seeds of flowers and trees that can be harvested in July are: wax plum, plum, hairy peach, mountain peach, elm leaf plum and so on.

two。 Transplanting, planting and potting

July is the main period of time for Chen to put grass flowers on the pot during the National Day, when the grass flowers transplanted into the pot can be sowing seedlings or cutting seedlings. After three months of careful maintenance, they bloom just during the National Day period for holiday decoration. They are mainly: a string of red, early chrysanthemum, thousand-day red, Xiaoli, Guinean impatiens, Longkou flower, marigold, peacock grass, ground skin, chrysanthemum, sulfur chrysanthemum, cockscomb and so on.

Tree transplanting is generally not carried out in July, but in some special cases, it is also feasible to transplant some flowering shrubs with soil balls, such as ten meritorious works, hypericum, golden leaf privet, red leaf Berberis, peach leaf coral, dragon cypress ball and so on. However, it is necessary to prune pertinently, set up a shed for shade in time, and increase the number of water spraying, and then transfer to normal management after its basic survival. We must not be careless.

III. Flower management

1. Watering

The flower species that enter the semi-dormant state at high temperature, such as safflower sorrel, geranium, golden bell, gentleman orchid, calla lily, begonia, sedum, longevity flower, cactus, crystal cactus, big flower rhinoceros, emerald beads, big string moon, Ruixiang, crab claw orchid, purslane tree, aloe, etc., due to high temperature, their growth activities basically stop and their metabolic level is very low. Watering should be reduced to keep the basin soil moist. And pay attention to shading and ventilation to create a relatively cool environment. If too much watering, it is easy to lead to rotten roots, but also seriously affect the recovery of its growth after autumn.

The species of flowers that entered deep sleep at high temperature, such as cyclamen, Lycoris, buttercup, purse peony and so on, showed that the aboveground stems and leaves withered, the underground nutrient fibrous roots withered, and spent the summer dormant in the soil with underground stems or tubers. For deep dormant flowers, stop watering, move to a cool place, and keep the pot soil not too dry.

For exuberant flower species, especially foliage plants, such as cycad, Magnolia, tortoise back bamboo, rubber tree, Magnolia, jasmine, Milan, pearl orchid, southern sequoia, bamboo taro, taro, red (green) gemstone, hulk, green emperor, green queen, pink leaf, Brazilian iron, rich tree, camellia, tea plum, peach leaf coral, torch fruit, daidai, lemon, Luohan pine, pomegranate, bauhinia, wisteria, rose, etc. It is not only necessary to increase the amount of water and times of watering, but also to give foliar spraying water and the combination of spraying and pouring properly. Especially when it comes to continuous cloudy days, due to the high temperature and dry air, it is also necessary to give watering and spraying, and must not be negligent. Once it is found that the basin soil is too dry and the leaves wilt, water should be sprayed on the leaves first, and then the roots should be watered after the leaves are erect again. Do not water the roots violently, otherwise it is very easy to cause the woody flowers to "fall green leaves", or lead to the rot of the vegetative fibrous roots of the plants, or even cause the death of the plants.

For potted plum piles, as the flower bud differentiation period is from July to August, appropriate "buckle water" should be given to promote the normal differentiation of flower buds. The method is to keep the leaves of pot plants curled inward slightly in order to control vegetative growth; if the vegetative growth of branches can not be controlled, only one leaf at the base can be cut off when 2 or 3 leaves are pulled out from the second shoot, and flower buds can still be differentiated in the axils of this leaf.

In July, watering potted flowers should avoid a few hours before and after noon, and it is appropriate to water before 10:00 and after 4 p.m., so as not to affect the growth of potted ornamental plants. If you encounter continuous rain this month, you should check the flowerpot in time after the rain, pour it when you find stagnant water in the flowerpot, and loosen the soil once after the pot soil dries up, so as not to cause rotting roots of potted plants.

two。 Fertilizer application

There are four types of ornamental plants that should be strengthened in July. First, the flowering period is particularly long, from spring and summer to autumn, such as Magnolia, rose, Milan, jasmine, etc.; second, the species of autumn flowers, such as chrysanthemum, sweet-scented osmanthus, hibiscus, etc.; third, the species of viewing flowers and fruits in winter, such as hawkdai, bamboo, wax plum, rhododendron, etc.; fourth, foliage plants, such as brown bamboo, tortoise back bamboo, spring feather, rubber tree, and so on. For the first three types of fertilization, in addition to the necessary nitrogen fertilizer, appropriate amount of phosphorus and potassium fertilizer should be applied to meet the overall needs of plants for nitrogen, phosphorus and potassium, and to provide adequate nutritional guarantee for their budding, flowering and fruit hanging; for foliage plants, it should be based on thin cake fertilizer or urea. In the method of fertilization, it is better to apply thin liquid fertilizer.

The grass flowers that should be fertilized in July are: a bunch of red (white, purple, pink), cockscomb, chrysanthemum, hundred-day red, thousand-day red, chrysanthemum, black chrysanthemum, petunia, golden bracts, shrimp flowers, Jianlan, marigold, purple jasmine, longkou flower and so on. Woody flowers are: crape myrtle, pomegranate, poinsettia, Michelia, sweet-scented osmanthus, camellia, tea plum, Fusang, jasmine, Prynne, Milan, evening incense, rose, begonia, mandarin duck jasmine, triangular plum, rhododendron, pearl orchid, wax plum, hibiscus, hibiscus, hibiscus and so on. There are many kinds of foliage plants, such as pineapple, Brazilian iron, brown bamboo, southern fir, synthetic taro, bamboo taro, hulk, ruby, cycad, rubber tree, tortoise back bamboo, Zhu banana and so on.

In July, fertilization must be stopped for dormant or semi-dormant ornamental plants, especially for those succulent ornamental plants, such as sedum, fairy pen, pine chrysanthemum, leopard skin flowers, etc., to prevent plant decay.

3. Pruning, picking buds

The ornamental plants that can top and sprout in summer must be species with exuberant growth, strong germination and resistance to pruning. Heart-picking refers to the direct removal of tender tip buds with fingers. The main bonsai plants suitable for heart-picking are: hammer elm, sparrow plum, Chinan, silk cotton wood, melon seed yellow poplar, wax plum, firethorn, Luohan pine, Tamarix, Elaeagnus angustifolia, banyan tree, white wax, maple, crape myrtle, June snow, Jiuli incense and so on. Pruning refers to the use of scissors to trim off part of the new shoot to promote the germination of the lower lateral buds to form a beautiful crown or tree shape. Most of the species of bonsai plants suitable for pruning are woody ornamental plants that are not easy to pick with their fingers, such as juniper, Platycladus orientalis, Sabina vulgaris, cedar, oak, cat thorn, cypress and so on.

For those potted flower species that bloom continuously for a long time, such as Milan, rose, jasmine, pearl orchid, etc., the stump should be picked in time, and the branches that have flowered should be shrunk in time, which can promote the germination and re-flowering of the lower lateral buds, while for rhododendron, camellia, tea plum, begonia, wax plum, plum, etc., the overlong branches of the crown should also be shrunk in order to form a better crown shape.

4. Shade

July is the month with the strongest sunshine and the highest temperature of the year, so special attention should be paid to shading management for potted ornamental plants.

For those ornamental plants that like shade or semi-shade, they must be placed under the shade to avoid damage to plants caused by the scorching sun. Such as ferns, hairpins, purple calyx, tortoise back bamboo, camellia, tea plum, rhododendron, pearl orchid, crane orchid, orchid, palm bamboo, rubber tree, red (green) gem, spring feather, pink leaf, green apple, pepper grass, orchid, hanging bamboo plum, Brazilian iron, unicorn leaf, pineapple, bamboo taro, auspicious grass and so on.

For the species that like the light, you can give enough light, such as pomegranate, wisteria, crape myrtle, pyracantha, jasmine, June snow, cycad, round cypress, Platycladus orientalis, peach blossom, plum blossom, wax plum, hammer elm, sparrow plum, triangular maple, black pine, bayberry, oak, golden pine, blue orchid, Milan, rose and so on. On the other hand, it is necessary to give proper shade to Luo Han pine, bamboo and cypress, Michelia mollissima, tiger thorn, cloud bamboo, Guanyin bamboo, five-needle pine and so on.

For small, miniature and shallow bonsai, because the temperature is too high this month and the air is relatively dry, in addition to giving necessary shade, flowerpots must also be buried in wet sand, which can reduce evaporation on the surface of potted soil and help to protect the nutrient fibrous roots of plants.

5. Flowers in the air-conditioned room

In an air-conditioned room, you should choose flowers with a higher degree of leathery leaves, or with thicker cuticle, slightly resistant to dry environment, and more resistant, such as rubber tree, star anise plate, ten merit, cycad, Nanyang fir, golden sunflower, sunflower, palm bamboo, Canadian jujube, pineapple, spring feather, tortoise back bamboo, goose palm wood, one-leaf orchid, peach leaf coral and so on. It is not suitable to choose kidney fern, colored leaf grass, hulk, taro and so on. In addition, in the management, attention should be paid to the combination of watering and spraying, and away from the air outlet of the air conditioner, so as to prevent the wind from directly attacking the plant, resulting in the withered tip and scorched edge of the leaves.

6. Pest control

When the new bud of ⑴ orchid spreads its leaves in July, the leaf tip is easy to be infected with anthracnose, which gradually spreads to the whole plant, and in serious cases, it will lead to plant wilting and death. The disease may occur all the year round, poor ventilation, high temperature and humidity, continuous rain, it is more conducive to the breeding and spread of bacteria. Ventilation should be strengthened and 75% of chlorothalonil wettable powder 800 times or germicidal Dan 500 times should be sprayed during the onset period for prevention and treatment.

⑵ when plum blossom, peach blossom, begonia, red leaf plum, cherry blossom, elm leaf plum and other stumps or trunk, there is a reddish-brown sawdust feces accumulation, mostly caused by longicorn beetle larvae, which can be controlled by artificial killing, injecting inhalant pesticides, plugging poison labels, burying carbofuran and other methods, which can effectively kill the larvae in the trunk. Pay attention to the injection of pesticides, do not use dimethoate, omethoate and so on, in order to prevent drug damage.

In July, ⑶ should timely control the wild borer of Euonymus tomentosa, Populus tomentosa, Populus tomentosa and Populus tomentosa. When the insect occurs seriously, it can gnaw off all the leaves. Once found, pesticides such as trichlorfon, dimethoate or permethrin can be sprayed in time. If a certain pesticide has been used for a long time, it has produced resistance and can be changed to a new type of pesticide.

In July, some areas of ⑷ will continue to see the leaves of citrus butterfly larvae harming new shoots, such as daidai, kumquat, golden bean, bergamot, lemon, fragrant circle, rue and so on.

⑸ harms ash insects of Ligustrum lucidum, Ligustrum lucidum, water wax and ash trees. The emergence period is from late July to late August. It is necessary to choose the right time to spray pesticides such as quick culling to prevent the disease from happening again in the coming year.

⑹ Japanese tortoise wax scale is the main pest that harms Populus tomentosa, Fawu, Haitong, Camellia, red leaf plum, cedar and so on. When it is serious, it is often covered with branches and leaves. The nymph hatching period is in the first ten days of July, which can be controlled by spraying dimethoate and quick killing pesticides in time.

Fourth, bonsai modeling

In July, due to the high temperature, low air humidity and the vigorous growth of plants, it is difficult to recover from infection after branch injury, so most species of tree stumps are no longer suitable for flat binding. Still can carry on the modelling is some adaptable, tolerant plant species, and the request is the spring pot refines the seedling or the plant planted on the ground. They are: Yingchun, Ginkgo biloba, Luo Hansong, Luo Hanbai, Cuibai, June snow, black pine, melon seed yellow poplar, bayberry and so on.

In July, the modeling of the plant should be careful, light and slow, slowly, not eagerly, too hard, otherwise it is easy to cause the branch and stem of the plant to break, endangering its survival.

Solar terms in mid-July: Lesser Heat on July 7th and Greater Heat on July 22nd. Key points of maintenance and management of flowers overwintering

Key points of maintenance and management of flowers and plants overwintering 1, cold protection in a simple plastic greenhouse with a temperature of not less than 0 ℃, you can put the following ornamental plants without freezing injury, such as Penglai pine, Tianmeng, one-leaf orchid, star anise plate, rhododendron leaf coral, sunflower, kidney fern, palm bamboo, Phyllostachys pubescens, Michelia, firethorn, camellia, cymbidium, cymbidium, Phoenix tail bamboo, phenanthrene, cycad and so on. Ornamental plant species with an overwintering temperature of not less than 5 ℃, such as southern fir, goose palm wood, rubber tree, jasmine, brandy, pearl orchid, pocket coconut, calla lily, spring feather, tortoise back bamboo, Jianlan, Mulan, Belgian rhododendron, triangular flower, cyclamen, primrose, five-colored plum, kumquat, daidai, lemon, loose-tailed anemone, geranium, mulberry, Buddha belly bamboo, etc., can overwinter in a double-layer plastic greenhouse. For the species requiring a winter temperature of not less than 10 ℃, such as variable leaf wood, taro, pepper grass, bamboo taro, rich bamboo, fishtail sunflower, Brazilian iron, rich tree, reticulate grass, pineapple, pink leaf, poinsettia, Cymbidium, Longtuzhu, golden bract, Milan, Phalaenopsis, Cartland, Magnolia, South American iron tree, red (green) gemstone, Oncidium, tiger orchid, etc., in a double-layer greenhouse with good sealing performance. It is also necessary to heat it up properly. in the particularly cold period, from 4: 00 p.m. to 9: 00 the next day, put a grass curtain on the roof of the greenhouse, and then remove it until the temperature gets warmer. For those more hardy potted and bonsai plant species, such as wax plum, plum blossom, begonia, Yingshanhong, pomegranate, hammer elm, sparrow plum, oak, crape myrtle, wisteria, yellow poplar, Luohansong, triangular maple, Cuibai, garden cypress, red cypress, bayberry, Chinese wolfberry, white wax, etc., generally will not be frozen when not less than-10 ℃; in particularly cold weather, cover with plastic film or soft grass to prevent cold.

Whether it is put in the greenhouse, greenhouse, or placed in the bedroom bonsai, potted flowers and foliage, fruit plants, in addition to maintaining the appropriate indoor temperature, but also pay attention to ventilation, can be in the highest temperature of the day around noon to open doors and windows to give ventilation, to prevent the occurrence of fallen leaves, flowers and fruits. In the ventilation, we must also pay attention not to let the cold air directly attack the plant, so as to avoid adverse reactions.

2. Watering most of the potted flowers and bonsai in the greenhouse and in the bedroom to keep the soil moist. If the temperature is too low and too much watering, it is easy to cause rotting roots of the plant. When the temperature rises, the amount of water can be increased and proper foliar spray can be given. For those potted flowers that blossom before and after the Spring Festival, such as camellia, tea plum, Belgian rhododendron, plum blossom, wax plum, melon chrysanthemum, primrose, longevity flower, hyacinth, European daffodil, etc., ornamental fruits such as daidai, lemon, bergamot, tangerine, golden bean, winter coral, rich seeds, Phyllostachys pubescens, etc., should not only keep the potted soil moist, but also spray the leaves to facilitate the expansion of flower buds. It can also increase the freshness of flowers and fruits. For most foliage plants in the shelving room, we should not only keep the basin soil moist, but also spray water on the foliage surface, and always keep the foliage surface clean; for those foliage plant species that are not very cold-resistant, such as Fendai leaf, fruit taro, bamboo taro, leaf-changing wood, silver queen, etc., when the room temperature is close to the minimum temperature they can bear, special attention should be paid to controlling the amount of water to ensure that they can survive the winter safely. The watering time in December should be 3 to 4 hours before and after noon, and the water temperature should be basically consistent with the air temperature and soil temperature, so as to avoid adverse reactions caused by low water temperature.

Newly transplanted flowers and trees outdoors should be checked frequently and replenished in time; for transplanted evergreen trees, foliar spray can be given around noon to prevent leaves from drying and falling off.

3. Fertilization should be stopped for most of the potted flowers and trees, foliage plants and bonsai in the general greenhouse, otherwise it is easy to cause the plant to rot and die.

Most of the green trees and flowers planted on the ground Such as Begonia, Magnolia, Magnolia, Magnol Cryptomeria fortunei, cedar, cypress, Robinia pseudoacacia, elm leaf plum, Yu Li, white silk plum, heather, bauhinia, hibiscus, etc. While ploughing the garden field in December, fertilizers such as cake fertilizer, pig and cow manure, pond mud and septic tank residue can be applied to the periphery of the plant root system, so as to lay a good material foundation for next year's growth and flowering. For potted flower species placed in the room from 10 ℃ to 15 ℃, such as camellia, tea plum, rhododendron, plum blossom, wax plum, golden bract, shrimp flower, pineapple, Ruixiang, melon leaf chrysanthemum, primrose, cyclamen, pedicel begonia, hyacinth, gentleman orchid, tulip, freesia, etc., 1.2% potassium dihydrogen phosphate can be applied to promote the pregnant bud and flowering of the plant.

4. Pruning hedges, green walls and ball shapes that have not been pruned in November. Hedgerows and green walls such as privet, lobular privet, Fa Qing, Populus tomentosa, Shu juniper, four seasons cinnamon, spinulosa heather, etc.; balls such as Chinese wolfberry, bayberry, heather, yellow poplar, Haitong, Admiralty, pyracantha, dragon cypress, juniper, etc., can be fertilized while completing pruning. The ground-planted flowers and trees that have not been pruned in November, such as rose, crape myrtle, palm, red leaf plum, heather, Fatong, plum blossom, wax plum and so on, can be pruned and fertilized around the root system after pruning. For bonsai plant species dominated by shearing, such as hammer elm, sparrow plum, medlar bone, Fujian tea, maple, oak, white wax, fire thorn, June snow, Luohansong, cypress, cypress, begonia, papaya, etc., continue to prune in December to lay a good skeleton for next year's growth; plants that have not changed pots for many years can be combined with pruning to change pots.

5. pest control can reduce the occurrence of diseases and insect pests in grape, begonia, rose, rose, camellia, crape myrtle and other flowers and trees that are prone to diseases and insect pests. At the same time, spray stone sulfur mixture for sterilization and disinfection. For powdery mildew of potted melon-leaf chrysanthemum and Botrytis cinerea of primroses, the former was controlled by triadimefon or thiophanate-methyl in time, and the latter was controlled by thiophanate-methyl. For the species of scale insects that are easy to appear in flowers and trees in the greenhouse, such as hadai, bergamot, cycad, camellia, orchid, etc., you can first wipe them with a dishcloth, and then use pesticides such as quick culling. When there is poor ventilation, aphids often appear on potted plants, such as Magnolia, Milan, daidai, rose, Fujian tea, etc., can be controlled by tobacco water. On the trunk and big branches of flowers and trees such as Haitong, sweet-scented osmanthus, Fatong, camellia, lobular privet, pyracantha, oleander, begonia, Magnolia, bauhinia, gardenia, cedar, heather, crape myrtle, wax plum, etc., there are many kinds of scale insects that often appear on the trunk and big branches of flowers and trees, such as horned wax scale, Japanese tortoise wax scale, red wax scale, shield scale, sagittal scale, pink scale, velvet scale, etc., at this time, spray and kill with high concentration of pesticides such as quinathulfan, quinathulene, buprofezin and other pesticides. Drug damage is rarely caused.

6. Composting fertilizer in order to raise seedlings and prepare culture soil next year, we can use winter leisure time to pour rapeseed cake, bean cake and tea seed cake into water tanks and pools and add water for sealed fermentation. Dry withered grass, fallen leaves, shrubs, branches, etc., are piled up in layers with the garden soil, ignited and burned to form burning soil, which is a good covering soil for sowing and raising seedlings next year. Compost, pond mud, chicken droppings and pigeon manure were mixed with garden soil and sealed fermentation, which can be used for topdressing seedlings and preparing culture soil in the coming year.

7. make use of the free time in winter to find an open space or pile up as much culture soil as possible in the shade of trees, so as to meet the need of changing pots and potting grass flowers next spring. Generally, there are 4 parts of garden soil, 2 parts of rotten leaf soil (or 2 parts of alpine humus soil), 1 part of fine sand, 1 part of piled sawdust, tobacco dust or bran ash, plus about 5% retted cake fertilizer and 2% to 3% compound fertilizer. Among them, garden soil and rotten leaf soil should be screened, gravel, tree roots and other sundries should be sifted, fully mixed, covered with plastic film, and can also be stacked indoors after 3 to 4 months. It can be used for changing pots or potting grass flowers.

8. For the garden used for sowing, cutting and planting seedlings next year, ploughing can be carried out in December; for the garden for sowing and planting seedlings, cake manure, barnyard manure, pond mud, etc., can be applied before replanting; do not make beds for the time being, go through winter freezing, and then dig ditches to make beds in the early spring of next year, which can greatly reduce the cost of seedling management and reduce the occurrence of diseases and insect pests. The ornamental plants suitable for bonsai modeling in December are: Luohan pine, Luohanbai, garden cypress, cypress, velvet cypress, Platycladus orientalis, Sabina vulgaris, black pine, five-needle pine, red pine, bayberry, wolfbone, holly, weeping spear, ginkgo, June snow, broom elm, finch, triangular maple, wax petal flower, Tamarix, pedicel begonia, weeping silk begonia, papaya begonia, melon seed yellow poplar, pearl yellow poplar, wisteria, purple myrtle, banyan, banyan, Fujian tea, white wax, oak and so on. For bonsai plants fixed with brown wire (rope) or wire, if it has been fixed for one year, or obvious constriction marks are found on the stem or branch, the original ligature should be removed and the wire or brown rope should be used for hanging traction. For plum piles, Luohansong, begonia, ginkgo, cypress, crape myrtle, etc., after some necessary pruning and plastic surgery, choose a good pot for planting and strengthen management, so that they can be used in public places or rooms for display in the coming year.

In winter, we must carefully manage some shallow landscape bonsai and tree stump bonsai: first, to prevent the roots of plants from frostbite in the basin soil; second, to prevent the disintegration of artificial cemented rocks caused by freezing; and third, to prevent plants planted on rockery from freezing or drying to death. It can be placed in an ice-free place and watered regularly so that it can survive the winter safely.
