Yew potted maintenance precautions:

1. Try not to spray fertilizer solution on the leaves of newly purchased yew potted plants when they sprout, because at this time the yew potted plants have not really survived or the leaves are too tender. If fertilizer is applied at this time, the leaves or buds will shrink and curl. Therefore, the normal germination of new roots is affected. The amount of water sprayed on the leaves should not be too much. The water droplets sprayed on the leaves can be seen but do not drip down. Spray two hours before dark in the afternoon, and do not leave water droplets at night (especially when the amount is large), otherwise it will affect the normal growth of young leaves or the leaves will turn yellow, affecting the healthy growth of plants. (The reverse side of the leaf is sprayed more than the front side, because the front side of the leaf has a waxy protective film, which will hinder the absorption of nutrients and water, while the back side of the leaf has no waxy layer, more stomata, and stronger ability to absorb water and fertilizer. So the back absorbs faster and more than the surface of the leaf). Once a day or two or three times a day, depending on conditions and temperature. Note that indoor ventilation needs to be frequent.

2. For newly purchased Taxus chinensis potted plants, due to the damage caused by part of the root system when transplanted from the planting base to the flowerpot, the nutrient supply between the root and the branches and leaves is unbalanced, especially for those potted plants with lush branches and leaves, the evaporation amount of the leaf surface is greater than the absorption amount of the root system. Under the condition that the pot soil is kept moist, the top leaf will curl and dry. At this time, it is best to properly trim the branches and leaves to reduce the water content of the branches and leaves. Excessive consumption of nutrients to restore root growth as soon as possible, at the same time to control watering, keep the pot soil slightly dry, in order to facilitate root growth as soon as possible, accelerate the recovery of normal supply of nutrients. At the same time Taxus has a strong ability to sprout, especially new branches strong ability to grow very resistant to pruning, survival will soon sprout new branches and leaves. When necessary, plant rooting or rooting agent can be used to irrigate the pot soil every seven days or so, and continuously irrigate three or four times (using better quality products and not too much water) so that the root system can grow quickly and healthily. Make root, leaf restore supply balance as soon as possible, make yew grow well.

Third, because the yew potted plant is planted in the pot of limited nutrients, about only about half a year of growth needs, or the current plant shape is larger, nutrient consumption is very large, so it is recommended that consumers had better replace the original pot as soon as possible after purchase. Because my company for more than a month of potted period, in the distribution company and stored for a period of time, plus yew like fertile loose soil. It is best to change pots as soon as possible. When changing pots, calculate the inner diameter of the pot. The inner diameter of the new pot should be at least five centimeters larger. Before budding in February and March every year, pour out the tree and pot soil together when the pot soil is not dry or wet. Try not to break the original soil ball, such as survival found that too many roots can be properly cut off bad roots, the tree into a new pot, filled with nutrient soil around gently press solid, only the pot of soil and roots close contact to improve survival rate, otherwise the plant is not easy to survive or grow exuberant. But also can not put the soil pressure too solid, such as too solid roots can not breathe air will lead to root rot, plant death. After planting, pour water immediately. And put the pot in the shade for a few days. After watering, the pot soil cannot be turned and pressed again, otherwise the pot soil is easy to harden, or the soil is too solid and poor ventilation is easy to cause rotten roots.

Four, yew bonsai fertilization methods: plant growth three elements nitrogen, phosphorus, potassium, nitrogen can promote the growth of flowers and branches; phosphorus can promote the formation of flowers and fruits; potassium can promote the growth of stems and roots.

Because bonsai is in limited pot space. In the limited cultivation soil, organic matter is decomposed into inorganic salts by bacteria and absorbed by the roots. As the yew grows, the nutrients in the pot soil gradually become scarce, resulting in insufficient supply for growth. Although the bonsai is prepared with good nutrient soil, do not fertilize it within three months after purchase. As long as every seven days to ten days in the evening about 1000 times the potassium dihydrogen phosphate solution or foliar spray. Control the amount of watering, do not water too much. Only when the leaf color becomes pale, the plant is thin, the leaf is yellow-white, the leaf edge and leaf tip appear "dry burning edge", and the leaf is prematurely aged and leaves are dropped, the 1000-fold solution of urea and 800-fold instant high-quality compound fertilizer solution of potassium sulfate is applied to remove the sediment and then irrigate the pot soil. It is best to use the fully decomposed light bean cake fertilizer (about 10%~15%) to avoid the trunk when applying, and try to apply it along the pot wall. Once every half month. The next day after fertilization, water is poured again to prevent the fertilizer from being too thick and diluted. The above two fertilizers can be used alternately, or two small pits can be dug in each pot to put five or six urea and seven or eight high-quality compound fertilizers. Cover the soil and water it to dissolve the fertilizer. Taxus potted landscape bogey fertilizer, thick fertilizer. Topdressing should be based on nitrogen and phosphorus, not too concentrated.

5. Watering method of bonsai: the principle is "not dry, not watered, watered thoroughly"

Water is an important part of flowers and trees, all life activities of flowers and trees must be carried out under the participation of water, whether photosynthesis or transpiration, are inseparable from water, water can maintain the cell pressure, so that branches and leaves straight. However, if the limit is exceeded, the growth of the plant will be weak. If there is too much water in the soil for a long time, it will cause yellow leaves, deciduous leaves, rotten roots, and even death.

1. Look at the surface color of the basin soil slightly lighter leaves slightly slightly curly, press the basin soil with your fingers and feel a little soft, tap the middle and upper part of the basin body with your finger joints when the sound is dull, do not water the basin soil, as long as the leaves are sprayed to supplement the moisture of the leaves. When the soil surface is white, press with fingers and feel that the soil is hard, a circle of cracks appear between the basin and the soil, tap the upper part of the basin body with finger joints to make a clear sound of "bang bang", and the young leaves of the new shoots wither, water the basin soil. Before watering, the crack between the soil and the basin should be compacted with hard objects before watering. When pouring water, the spoon should be close to the edge of the basin. Pour water into it at once, and pour it thoroughly at one time to make the basin soil absorb enough water. If a small amount of water is poured into the basin for a while, water will flow out quickly from the basin bottom, indicating that the gap between the soil and the basin is not completely compacted. The object should be used to compact the gap between the basin wall and the soil before watering. When the structure of the basin soil is normal, it is good for about 40 seconds to one minute after watering. The water temperature must be similar to or consistent with the temperature at that time. When watering with tap water, put the water in the sun for about three hours before watering, because light helps to decompose the oxides in tap water and can increase the water temperature. Can also put water in a large basin for half a day or a night to irrigate, bonsai more water on the best large tank, so that the water temperature as close as possible to the temperature, soil temperature. Especially in hot seasons, besides watering the pot soil, spray water mist on the leaves to keep the leaves moist is beneficial to growth. Basin soil can be kept a little dry can not be too wet basin more often must be combined with the actual situation of each basin to check, pay attention not to leak irrigation not more irrigation.

2. Taxus leaves are evergreen all the year round and suitable for indoor display. But yew potted plant is not easy to put in the air outlet, otherwise it will increase the evaporation of water in yew leaves, easily causing rapid dehydration of yew branches and leaves, causing curling and drying. If placed in the air-conditioned room every day air conditioning should be carried out daily foliar spray, maintain foliar humidity, and put a basin of water indoors. If there is heating in the northern winter room should be farther away from the radiator, and put a basin of water on the radiator to increase indoor air humidity. Summer and autumn temperature more than 30 degrees Celsius should strengthen shading cooling work, can be moved to the north of the ventilation room. Water can be sprayed to cool down when necessary to create a cool and humid environment for the growth of Taxus. And avoid direct sunlight from the west to the room on the yew bonsai. In winter, the watering amount of bonsai should be controlled to avoid long-term excessive humidity of pot soil. Due to the lack of vigorous growth of plants in winter, the volatile water content of leaves is less. If the pot soil is too wet for a long time, the surface of the pot soil will be hardened and airtight, which is easy to cause the occurrence of rotten roots of plants. Yew in indoor breeding must pay attention to indoor ventilation.

3, yew planting soil should be loose, rich in humus, fertile, slightly acidic soil (PH=5.5~7), yew bonsai can not pour tea water, if often pour the rest of the tea water, because tea contains theophylline, and other alkali. It will change the pH of the soil and will also have a relatively destructive effect on the organic nutrients in the soil. It inhibits the growth of Taxus chinensis and causes excessive soil moisture, hinders the ventilation of pot soil, and causes the occurrence of root rot and stem rot. A week or so with conditions, the yew potted plant was moved to the balcony at night to receive dew and placed in the sun for about one or two hours in the morning to receive light (before 10 am), which is conducive to the growth of yew and improve disease resistance. Summer and autumn season to prevent the sun from shining directly through the window on the yew, in order to prevent high temperature burn leaves affect the ornamental value.

VI. Points for attention

1, yew due to small trees to pay attention to the regulation of light, need light but not too long in the strong light, generally summer and autumn every day before 10 o 'clock or after 5 o' clock sun for about two hours can be. Usually receive more scattered sunlight. Otherwise, the leaves will be burnt by strong light and the tips of the leaves will be scorched yellow, and the indoor ventilation will be maintained, so that the indoor air will not be too dry and there will be poor growth phenomena such as wilting and drooping.

2, the new bonsai such as the emergence of dark yellow leaves without luster, the top of the new shoots appear withered phenomenon is generally watered too much soil hardening airtight so that part of the roots rot, water absorption. The ability to absorb fertilizer is weakened. If the symptoms are light, the amount of watering should be controlled, and the topsoil of the basin surface should be gently picked up with hard and blunt objects to make the basin soil breathable. Every night, it can be moved to a place where dew can be accepted. At 8:00 a.m., it can be moved to a shady place, which is conducive to the healthy growth of roots. Such as short-term leaf yellowing, leaf curl, it means that the root rot is serious, because immediately turn over the pot to check the root rot condition,(normal fibrous root is full white shape), such as more than half, generally save not live.

3, the old leaves from bottom to top yellow leaves, but the new leaves generally grow normally, usually when watering is not a one-time irrigation, irrigation is too little caused by root water shortage. Sometimes the top leaves are dry and curly, and the dry leaves fall off, but the old leaves grow normally. Generally, it is also caused by lack of water at the root. It should be watered thoroughly at one time. When watering, be sure to first compact the cracks along the basin with objects to prevent water from pouring down quickly from the cracks. The false image of watering will cause the root to die due to lack of water over time. Moved outdoors at night to receive more rain and dew, morning and evening to receive two hours of sunshine to restore the growth of Taxus.

4. Taxus chinensis is suitable for weakly acidic soil. If it is irrigated with alkaline water for a long time, it will cause the leaves to change from green to yellow, and even the leaves to fall off. Due to the addition of acidic nutrients or spraying of leaves or watering pots with two-thousandth ferrous sulfate solution, once every ten days, three times in a row. It can make the leaves turn green due to alkali yellow.

5. In March and April of each year, Taxus chinensis will sprout a large number of buds, which will consume a lot of nutrients. At this time, the buds growing inward can be removed to prevent the branches from being too dense and not ventilated to make the leaves yellow or fall off. To cross branch, introvert branch excessive long branch thin cut, can improve ventilated. Light transmission, and can save excessive consumption of water and nutrients, in the bud just sprouted when the leaves had better not spray liquid fertilizer, or in the root irrigation fertilizer.

6, the normal amount of fertilizer if only urea topdressing nitrogen fertilizer, the concentration is generally one thousandth, if only potassium dihydrogen phosphate topdressing phosphorus fertilizer, the use of concentration of one to two thousandths, a topdressing interval of seven to ten days.
