Question 1: When should I change the pots of winter jasmine? Generally, the pots should be turned over once every two years, and the time should be after the leaves fall in spring or autumn. When turning the pot, it can be combined with pruning the root system, cutting off dead roots and long roots, which is beneficial to the development of fibrous roots. Bean cake crumbs can also be placed at the bottom of the basin as base fertilizer.

Question 2: When will the winter jasmine take root? Body heel exposure method of winter jasmine velvet

1. Rooting method: If you want to expose the root system of the stump bonsai from the basin surface to increase the quaint dragon bell of the bonsai, you can raise the root system year by year when changing the basin, so that the new root system at the lower part can take root deeply, and the proposed root system on the basin surface will be thinned and deleted appropriately, and the fine roots will remain thick, some will fly in the sky, and some will emerge to drill their tails, such as dragons entering the hole, showing their magical powers.

2. Pile up soil to expose the roots: Tamarix species with dry roots and adventitious roots can be lightly rowed on the stump in spring, piled with wet bacon to soak the soil, and after the new roots are aged for 2-3 years, remove the soil to expose the roots, and then perform artistic pruning on the exposed roots as required.

3. Sleeve root exposure method: Some tree species that are difficult to germinate adventitious roots, such as pomegranate, can be peeled for a week in a dry position higher from the basin surface after the crown is trimmed and shaped, then dried in the air in a circular way, and then a plastic bottle filled with cola is broken, and bacon soil is filled in the sleeve, and sometimes water is poured to keep moisture. After 2-3 years, the roots are exposed again, and the shape becomes thinner. Roots grow from above and drill out from below.

4. Ring-exposed method: For tree species with soft roots and branches, such as Ginkgo biloba, Xiang Jie, Daphne odora, etc. The elongated branch roots can be exposed in a ring, and then the root tails are buried in the soil to strengthen the roots. Moreover, the elongated trunk and backbone branches are also wearing bow tie rings, which are butted and shaped, so that the branch rings echo the root rings up and down, which is very interesting.

5. Crab claw orchid root exposure method: cut the periphery of the formed stump base, bury it in soil and dry it, so that adventitious roots germinate around it. After the new roots are lignified, ten of them are selected as the shape of crab claws, that is, two large ones are crab claws and eight small ones are crab feet, which are raised like crab feet and buried underground. This can not only renew the root system, but also increase the artistry of bare roots of bonsai.

6. Expose the roots with boulders: If you want to cultivate bonsai with stones, you can choose tree species with inconspicuous main roots and elongated lateral roots as pile materials, such as Yingchun and Murraya. Cut off the main root, surround the lateral root on a rectangular natural ornamental stone, and then plunge the root into the basin soil. Like a golden rooster holding an egg.

7. Root exposure method: firstly, the natural ornamental stone formed by artificial drilling is used as the attached stone of the tree stump, then a slender pile material is selected, the root head passes through the hole of the attached stone, and it is wound around the attached stone in the exposed time, and finally it is drilled into the basin soil to develop a root system.

8. High-exposed root method: If you want to cultivate a potted plant with exposed roots and dragon-wrapped columns, you can choose the root system of the same tree species as the root grafting, graft it on the upper end of the trunk, wrap the root grafting around the trunk, and then put a long tube of culture soil on the trunk to keep the root grafting moist, and plant the root tail in the pot soil. After the root is grafted and healed, the sleeve and soil are removed, revealing the posture of the dragon around the column.

9. Exposed Root Method: This is a form of stump bonsai that combines natural root art with bonsai. Underground tuberous roots, such as pictographic root materials such as ginseng or Polygonum multiflorum Thunb, are selected as pile materials to expose the basin surface, and the lower taproots and fibrous roots are planted in the basin soil. After survival, new roots germinate on the pictographic root crown, forming a plant crown, including Polygonum multiflorum Thunb, vines and so on. You can stand like a scaffold.

10, hanging roots and exposing roots method: Ficus carica which can germinate aerial roots is selected as the pile landscape material, planted in a rectangular pot, and covered with a rectangular glass cover after the branch crown is formed, so as to increase the humidity in the pot, promote the aerial roots hanging on the horizontal main branches of bonsai to germinate, form new roots after being buried underground, and then the aerial roots become new stems, which can be cultivated several years later.

Question 3: When is the best time to change potted plants during the Spring Festival? The time from bloom to new leaves is the best time to change potted plants.

Question 4: Can I change the pot of winter jasmine now? If the original basin is transplanted, it can be changed all year round. But if it is loose soil, it is best not to change it.

Question 5: When will the winter jasmine be planted? Usually after the flowers wither or in mid-September. Strong adaptability to spring, light-loving, cold-resistant, drought-resistant, alkali-resistant and waterlogging-resistant. The soil requirement is not high, and it can grow in slightly acidic, neutral and slightly alkaline soils, but it grows best in loose and fertile sandy soil. During the Spring Festival, those newly planted or changed pots should be watered, kept in the shade for about 10 days, and then placed in a semi-cloudy and semi-sunny place; Cure for a week, and then put it in a sunny, well-ventilated and humid place for curing. In winter, the pots planted with spring flowers in the south can survive the winter safely as long as they are buried in the soil in the leeward and sunny places, while in the north, they should be moved indoors when the temperature is low (about 5℃) in early winter.

Question 6: The leaves of winter jasmine dried up after changing pots, and now 90% of them are dead when changing woody flower soil or changing pots. Because of the hot weather, plants are in the growing season.

Question 7: Can I change pots for piles that have been kept for one year? Yes, as long as the situation is prosperous.

Question 8: Can I cut the winter jasmine? In what season, should it be planted in soil or water? Water can be inserted into the soil, as follows:

Water insertion method

First, the time of water insertion: water insertion can be carried out all year round. In winter, you can put the water container in the indoor sunlight, and in summer, you should pay attention to shading to prevent the sun from exposure. When inserting water, the water temperature should be kept at 15℃ to 20℃, and the cuttings can take root quickly and have high survival rate.

Second, water cuttings: cuttings are selected from branches with vigorous growth and full buds in that year. The length of hungry cuttings is generally 8cm ~ 12cm, and 2 ~ 4 knots can be left. Cut about 2 mm below the lowest node and bind it every 10. If there are too many leaves in the upper half of the cuttings, they can be removed appropriately to facilitate rooting.

3. Water injection container: the container is a large-caliber basin or a shallow-bottomed tank. It must be cleaned before use.

4. Water insertion method: the container is filled with clean rainwater, river water or tap water to a depth of 8 cm to 10 cm, then the bound cuttings are put into water to a depth of 4 cm to 6 cm, and then the container is placed in an outdoor ventilated and semi-cool place. The water quality must be kept fresh and clean, and the water can be changed once every 3 to 5 days. Generally, tumor-like healing tissue can be produced about 20 days after implantation, and fibrous roots can grow from 35 days to 40 days.

5. Planting in time: When the fibrous root grows to 3cm ~ 5cm, it must be planted in time, and the operation should be careful to avoid damaging the root system. General shading treatment 10 days can be used for normal management.

Soil insertion method

(1) Cutting: Cut off the eye-cutting branches from late February to early March; Cut off semi-mature branches in June-July; Mature branches were cut off in early September. After flowering, cut the branches into 4-5 cuttings and insert them in the inner pot; You can also cut it in the open field in July. After transplanting, shade, pay attention to watering and keep the soil moist, so it is easy to take root. After survival, it can be planted alone, put into pots in early September and put into greenhouses for the winter.

(2) ramets: most ramets propagate in spring and autumn, but the survival rate of ramets in spring is the highest, which can be combined with early spring transplanting and is very easy to survive. Generally, perennial mother plants can be divided into 10-20 clusters with two or three stems and branches, which can bloom after planting.

(3) layering: you don't need to scrape the layering, you can use hard strips or twigs, which will take root quickly and easily after contacting the soil. Hard branch layering is generally carried out in March-April, and the growing season is carried out in May-June. Generally, it takes 2 months for hard branch layering to take root, and it takes 1 month for soft branch layering to take root. After survival, they were separated from the mother plant and transplanted in the following spring.

Management: Winter jasmine has strong adaptability and is easy to cultivate and manage.

Ground planting: Generally, applying decomposed organic fertilizer once in summer can promote flower bud differentiation, which is beneficial to overwintering and flowering in the coming year. Water 1-3 times before flowering to flowering. According to the degree of soil dryness and wetness, intertillage should be used to weed in summer, and it is best to apply more fertilizer 1 time every autumn after defoliation. Always pay attention to irrigation before the rainy season comes. No topdressing during the growth period, and no irrigation after beginning of autumn, in case the branches are too long and tender to overwinter safely. After the seedlings are planted, they can naturally grow into clumps and shrubs, or they can bud the stem base of the seedlings, choose 1 central main branch, leave the base 30 cm short, let the side branches diverge from the main branch, and pick the core of the side branches 3-4 times a year to promote the increase of flower branches.

Potting: First, put the plants cultivated in the open field into the pot before winter, trim the old piles to keep proper shape, and put them in a warm place to promote flowers if necessary. In this method, it should be noted that the soil must be kept moist after the pot is released to facilitate survival. The method of forcing flowers is to cut off the branches of potted Jasminum nudiflorum and put them into water two or three weeks before flowering, and control the greenhouse temperature to be between 10- 1572, and bloom on New Year's Day and Spring Festival respectively. The second is potted plants. This method is to go to the pot to welcome the spring, and cut short branches and change pots for fertilization every year after flowering, so as to facilitate the next year's flowering. If you want to prune the potted Jasminum nudiflorum into a big branch shape, you can leave 3-4 buds from the base of the stem after flowering, and all the buds in JUNG WOO are cut off, as well as the twigs that disrupt the tree shape and the withered branches that are too dense with pests and diseases.

Pest control: There are few common pests and diseases in winter jasmine, mainly aphids. The control method is to spray 40% dimethoate EC, dichlorvos 1500- 1800 times or use tobacco liquid.

I hope it helps you:)

Question 9: Will you spray water in spring after changing pots? Vatican in Degang Guo

Question 10: How to raise Jasminum nudiflorum mainly by cutting, or propagate by layering.

Cutting can be done in spring, summer and autumn. Cut off semi-lignified branches with the length of 12- 15 cm, insert them into the sand, and keep them moist for about 15 days.

Take root. Layering: Bury the longer branches in the sand without being scratched, take root after 40-50 days, and transplant them separately from the mother plant in the next spring. The division of plants can be carried out when they sprout in spring. When transplanting in spring, cut off the above-ground branches.

Part, need to bring lodging soil. During the growth process, pay attention to the fact that the soil can't accumulate water and be excessively dry, and properly fertilize 2-3 times before and after flowering. Prune and reshape in autumn and winter to keep more new flowers. Pests and diseases often occur leaf spot disease and dead branch disease, and 1500 times of 50% bactericidal wettable powder can be sprayed. Insect pests do great harm to aphids and giant salamander, spraying 50% phoxim EC 1000 times. Winter jasmine is warm and cold-resistant. The flowering period of the Spring Festival is affected by the temperature, and it is open from late October to April from south to north at 65438+/kloc-0. If you want to blossom in the Spring Festival, you can move the flower buds into the sunny room at 12 ~ 16℃ 2 ~ 3 weeks before the Spring Festival, and water them for 3 days 1 time, and often spray water on the branches and leaves. If the flowers don't bloom before the Spring Festival 1 week, the room temperature can be raised to 20.

You can also dry-cut, that is, cut the whole seedbed and then irrigate it with water. Cutting can be carried out from the middle of 10 of 65438 to the middle of 10 of 65438 or in spring. After rooting, it can be planted alone, divided into plants or propagated in layers.
