What are the cultivation methods and precautions of Yushu?

First, the breeding method.

1. Soil requirements.

Cultivating jade trees should use loose and fertile soil with good drainage, peat soil and humus contain a lot of organic matter, and peat soil has strong air permeability, very suitable for cultivating jade trees, and the soil is best to use the same amount of humus, peat, vermiculite mixed preparation, and the correct soil will make the jade tree grow more vigorously.

2. Watering requirements.

In the cultivation methods and precautions of the jade tree, the spring and autumn growth period should be watered once every 3 4 days, the temperature is high in summer, the water evaporates quickly, it should be watered once in 1 2 days, and the summer watering should not be watered at noon when the temperature is high, it is more suitable in the morning and evening, the temperature is low in winter, the growth of the jade tree is slow, and it is watered once in 1 2 weeks.

3. Light temperature.

Yushu likes a warmer growth environment, the most suitable growth temperature is between 20 and 30, the summer high temperature should be shaded and maintained, especially when the temperature exceeds 35, we must do a good job of cooling, the temperature in spring and autumn can be placed in the sunny place full sun maintenance, the winter temperature is low, as much sun as possible, but also to ensure that the temperature is not less than 10.

4. Fertilization requirements.

The jade tree grows faster, and the demand for nutrients is also large, especially in the spring and autumn growth period, generally fertilized once in 2 weeks, you can use well-rotted organic fertilizer or cake fertilizer, if it is a compound fertilizer, nitrogen fertilizer is the mainstay, which can promote the jade tree to grow more green leaves, and the leaves are still very luxuriant, pay attention to fertilization, the amount of fertilizer can not be too much, do not use unrotted raw fertilizer and fertilizer with too high concentration.

Second, the precautions for breeding jade trees.

1. Prune regularly.

The jade tree grows fast, and often has long branches and leaves or too dense branches and leaves, which not only affects the appearance but also is not conducive to the growth of the jade tree, so the jade tree needs to be pruned regularly in spring and autumn, first cut off some weak and diseased branches, and selectively cut off some long branches, and carry out thinning and pruning for dense branches to enhance air permeability and light transmittance.

2. Pest control.

The prevalence of jade tree is higher, the most common is leaf spot and anthracnose, if not treated in time, it will cause the whole plant branches and leaves to yellow and wilt, spray once a week with 50% anthrax Fumei wettable powder 500 times, spray three times in a row, if it is infected with scale insects, spray 40% dimethoate solution.

1. Illumination. It loves light, and it is important to keep it in a sunny and warm environment all year round, which is the key to flowering.

2. Temperature. Spring and autumn are the suitable growth periods for jade trees, and the suitable growth temperature is 20-30.

In summer, it is necessary to shade and avoid direct sunlight when the temperature exceeds 38, and the growth is slow.

In winter, keep it indoors in a sunny place and keep it at room temperature of 7-10. If the temperature is as low as 0 or less, it will freeze to death.

3. Watering. Yushu is a succulent and pulpy plant, very drought-tolerant, usually should not be watered too much, to see dry and wet, dry and then watered.

During the growth period, the jade tree should be watered once every 2-3 days, but it should not be waterlogged, and when cultivated outdoors, it is necessary to avoid rainstorms, otherwise the roots will accumulate too much water, and it is easy to cause rotten roots to die.

In July and August, when the temperature is high and humid, watering is strictly controlled. And to strengthen ventilation, otherwise it is easy to cause fallen leaves, it is best to put it in the semi-shade for maintenance.

Watering gradually decreases after autumn, reduces watering in winter, and the potting soil is slightly drier.

Fourth, fertilization. In the growth period, top dressing should be applied, and generally 2-3 times a month to apply the well-rotted and thin cake liquid fertilizer. In order to keep the jade tree plump, the fertilizer water should not be too large, so as not to cause growth.

5. Precautions.

1) Trim. Pruning can be done according to individual preferences. Prefer the crown of the tree to be round and plump, prune off the long branches, too overlapping and crowded branches, so that the outer crown of the plant is complete, and the internal branches are sparse and dense.

If the tree is old, the old trunk is thick, and the crown is not very round, it can be pruned or stump bonsai style, and some branches and leaves can be cut off according to the needs of the shape.

2) Change pots. It is necessary to change the pot every spring, and when changing the pot every year or putting it in the room in autumn, attention should be paid to plastic pruning to make the plant shape more simple and elegant.

When the root length of the jade tree seedling reaches 2-3 cm, the seedlings with good root growth are selected and potted. It is best to choose a purple sand basin with good drainage and air permeability. When potting, first put 2-3 cm thick coarse-grained substrate or ceramsite at the bottom of the pot as a water filter layer, sprinkle a layer of fully decomposed organic fertilizer, about 1-2 cm thick, and then cover with a layer of nutrient soil, about 8-10 cm thick, and then put in the plant, separate the fertilizer from the root system to avoid burning the roots.

The culture soil used for potting can be mixed with 3 parts of humus, 3 parts of saprovirus, 3 parts of coarse sand, and a mixture of grass and bone meal. After potting, pour water once, and put it in a slightly shaded environment for a week, and transplant it to a sunny place such as a balcony after it is fully viable. After that, the pot is changed once a year in early spring, and fertile soil is added to improve the fertility and air permeability of the soil box.

After depotting, the roots are washed directly and then watered, which is not suitable for pruning water cuttings. The root system of the jade tree is underdeveloped, the aboveground part is wide, some are top-heavy, and the bottom of the vessel can be fixed with pebbles and colored stones. In summer, it can not be raised with nutrient solution, directly with clean water, and the water should be changed once every 3-5 days.

The jade tree should be placed in a well-lit indoor environment, otherwise the leaves will turn yellow and fall off.

Potted plants can be mixed with a ratio of 1:1 between sand and gravel soil and humus, and the soil quality is required to be loose, breathable and well drained.

The jade tree is resistant to shade and strong light, and can be placed in the semi-shade in summer to maintain, and in spring and autumn, it is necessary to give the jade tree direct sunlight so that photosynthesis can accumulate nutrients. In winter, it can be cultivated indoors in a place with bright light.

The suitable growth temperature of jade tree is 20-30, so spring and autumn are more suitable for the growth of jade tree. Too high a temperature will accelerate the aging of the jade tree, and should be shaded accordingly when the high temperature is high in summer. When it is too cold in winter, it will cause the growth of jade tree to grow slowly, and dormancy will occur below 5, so it is suitable for indoor cultivation and can be kept at room temperature of 7-10.

Add an appropriate amount of basal fertilizer to the bottom of the pot before soil change or planting, and the basal fertilizer can be decomposed organic fertilizer, such as manure, bone meal and cake fertilizer. Yushu is a succulent plant that looks at the leaves, and can be used with slow-release fertilizer every day, which is long-lasting and mild, and can be used about once every 2-3 months. During the growth period of the jade tree, apply the ripe and thin cake liquid fertilizer 2-3 times a month.

Before frost falls, stop fertilizing.

The jade tree has different water requirements at different stages of growth. Generally in spring and autumn, the growth rate is fast, about every 2-3 watering, and the potting soil is kept slightly moist. In summer, the temperature is high, the water evaporates quickly, and it needs to be watered once every 1-2 days.

In winter, the growth slows down, and it is watered about 1-2 times every half month.

The jade tree is an ornamental plant, and if you want to improve the ornamental nature of the jade tree, you must do a good job of topping. When the jade tree grows to 8-10 cm, you can start the first topping, which is used to control the height of the jade tree and prevent it from growing. Note that the jade tree is not tolerant to waterlogging and is afraid of water and rotten roots, so do a good job of ventilation every day.

Do you know these cultivation methods and precautions for jasper?

The cultivation methods of jade trees are: sufficient sunlight, suitable temperature, appropriate amount of water, proper application of fertilizer, and proper pruning. Precautions are not to expose to the sun, timely drainage in the rainy season, and disease prevention.

First, the cultivation method of Yushu

1. Sunshine. The jade tree is shade-tolerant and afraid of strong light, so it can be maintained in a semi-shaded place in summer, or shaded by 50%, which can make the leaf color more beautiful. In spring and autumn, the jade tree should be given direct sunlight exposure so that photosynthesis can accumulate nutrients. In winter, it can be cultivated indoors in a place with bright light.

2. Temperature. The suitable growth temperature of jade tree is 20-30, so spring and autumn are more suitable for the growth of jade tree. Too high a temperature will accelerate the aging of the jade tree, and should be shaded accordingly when the high temperature is high in summer. When it is too cold in winter, it will cause the growth of jade tree to grow slowly, and dormancy will occur below 5, so it is suitable for indoor cultivation and can be kept at room temperature of 7-10.

3. Moisture. The jade tree does not have high requirements for water, and during the growth period, it should be watered every 2 to 3 days to keep the soil moderately moist. However, it is necessary to control the amount of watering, as a large amount of water is easy to accumulate water and rot roots, and a small amount will lead to drying of the potting soil and accelerating the fall of leaves. In summer, under the condition of indoor ventilation and cooling, more watering can be done to promote growth; In winter, the amount of watering should be reduced, and watering every 7 to 10 days is sufficient.

4. Fertilizer. Yushu likes fertilizer, but the requirements for fertilizer are not high, and proper application of fertilizer can promote the growth of Yushu. During the growth period, it is suitable to apply top dressing, such as rotting fertilizer or cake fertilizer, etc., and the frequency can be kept at 2 to 3 times per month. It should be noted that the fertilizer water should not be too large when fertilizing, so as not to grow the plant and lose its round shape.

5. Pruning. Pruning can be done according to individual needs and age of the tree. If the tree is younger and the crown is more abundant, its long branches and overlapping staggered branches can be cut off to obtain a round whole plant shape; If the tree is older, the crown is sparse, and the branches are thicker, the misaligned branches can be properly pruned to obtain a pile-shaped bonsai.

Second, the precautions for breeding jade trees.

The jade tree should not be exposed to the sun, and in summer, the strong sunlight will burn the leaves, causing the leaves to shrivel and yellow. In the rainy season, it is necessary to drain the water in time and do not let the soil basin accumulate water. When pruning, it is necessary to cut off dead branches and diseased branches, and do a good job of ventilation to prevent disease infection.

In winter, you can put it on a sunny balcony and turn the pot every 30 days to keep the light even.
