What are the precautions for camellia planting? Thank you, teacher

Good morning! One is to pay attention to the temperature. Camellia is not cold tolerant or heatstroke-resistant, its most suitable temperature is 18-25 degrees, so the ambient temperature is not too high and too low, otherwise it will affect its growth, especially in winter, the indoor temperature must be above 3 degrees, if it is lower than 0 degrees, it will be frostbitten.

The second is to pay attention to the light. Camellia should avoid strong light, so you must pay attention to the sun when planting, spring and autumn require sufficient light, but in summer, you must avoid being exposed to direct sunlight, as long as the camellia is exposed to strong light for too long, it is easy to die, if there is a condition, it is best to transplant it under the canopy.

Third, we should pay attention to reasonable fertilization. Camellia is more like fertilizer, so special attention should be paid to the use of fertilizer in the whole breeding process, such as adding phosphorus and potassium fertilizer to the pot, but there is also a degree of fertilization, must not be too much, generally fertilized about 3 times in the past six months after flowering, fertilization once in winter, in order to make the flowers more beautiful, it is best to put more phosphorus fertilizer in the fertilizer.

Fourth, we should pay attention to reasonable watering. Camellia likes a moist environment, so we must pay special attention, not too dry, not too wet, can not be dry and wet, generally in the spring can be watered more, so that it is conducive to germination, in summer to be watered twice in the morning and evening, the best time to water on the leaf, do not water when the plant is at a high temperature, autumn and spring are the same, but in winter watering should be noted, it is best to water before and after the plant, and do not water every day, it is best to water once every two or three days.

Fifth, we should pay attention to the pruning of flower branches. The pruning of camellia is very important, generally it is to cut off the branches and branches that affect the shape of the tree, the diseased and weak branches, as well as the finishing of the flower buds, once the flower buds are too dense, they should also be combed, and the flowers should be picked in time after they wither, which can reduce the consumption of nutrients.

Sixth, it is necessary to turn over the pot. Many people will ignore this, many people will not turn over the pot when they are planted, in fact, this is very wrong, camellia generally has to be turned over once every two years, to change a large pot, so that it is conducive to its growth, the time to turn the pot should pay special attention, it is best to pay attention to the step when turning the pot, do not remove all the old soil, but also add a small amount of base fertilizer to it, and then water.

Seventh, pay attention to the prevention and control of pests and diseases. Camellia is easy to get sick, there are two common diseases - black mold, anthracnose, at this time only need to spray the degree of Bordeaux liquid, the pest of camellia is mainly tea tip moth, then the main cut insect tip can be.

Eighth, pay attention to the selection of suitable soil. Soil is the root of camellia growth, all the nutrients of camellia are obtained from the soil, so the requirements for the soil are quite high, generally its soil contains humus is higher, the pH value is between, slightly acidic, its optimal soil configuration is: 50% of mountain soil, 40% of sawdust or edible fungus residue, 10% of cake fertilizer powder or livestock manure and phosphorus fertilizer powder.

Nine is to pay attention to air circulation. Camellia grows in the place of air circulation requirements are extremely high, it is most suitable to grow in the breeze, but the camellia is very afraid of the northwest wind and strong winds, because the northwest wind and strong winds are easy to make the water evaporate too fast, and the supply and demand of camellia are out of balance, which is not conducive to the growth of camellia.

FYI.

Family flower raising knowledge! The little brother teaches everyone the precautions for cultivating camellias, so let's learn it quickly.

1. Clay pots should be used for potted camellias, especially young camellias. The potting soil can be prepared with 6 parts of humus, 1 part of cake fertilizer residue, 3 parts of sandy loam, or 3 parts of humus, 4 parts of sandy loam and 3 parts of compost, and the tiles are spread at the bottom of the pot to facilitate drainage. Potting should be carried out in early spring 3 April or late September to early October, when planting, the bottom of the pot is covered with broken tiles to facilitate drainage, and no base fertilizer can be applied to avoid burning new roots.

2. When potting, plant small soil ball cuttings in the pot. After planting, water thoroughly, subject to water seepage at the bottom of the pot, placed in a ventilated shade, pay attention to humidity, if necessary, cover a plastic bag, the temperature in the bag should not exceed 25 degrees, otherwise it is difficult to survive. After 8 to 10 days, place in a ventilated semi-shaded place.

During the growth period, watering should be based on seasonal changes to keep the potting soil moist as the principle, too dry and too wet is not conducive to plant growth.

3. During the growth and germination period of camellia, the amount of watering should be gradually increased. After the new shoots stop growing (around late May), watering should be controlled appropriately to promote flower bud differentiation. During the rainy season, it is necessary to prevent the potting soil from accumulating water and rotting the roots.

4. In summer, the high temperature should be watered once in the early morning and once in the evening, and sprayed around the plant at the same time to increase the air humidity. Residents of high-rise buildings can leave it in the living room or hallway for the summer, and move it to the balcony before 9 a.m. or after 5 p.m. In winter, when the plants enter the dormant period, the number of watering should be reduced; Top dressing should be mainly decomposed thin liquid fertilizer, and thick fertilizer and raw fertilizer should be avoided.

5. In early spring, top dressing is liquid fertilizer based on nitrogen fertilizer, 1 time in 10 days, 1 2 times in a row, to promote branch and leaf growth. 5 In August, nitrogen and phosphorus combined and phosphorus-based fertilizer should be applied to promote flower bud differentiation. 9. In October, phosphorus and potassium fertilizers were applied to promote further growth of flower buds.

Fertilization is generally not applied in winter. Generally, small seedlings and weak seedlings should be less nitrogen fertilizer.

6. Pay attention to stop watering before fertilization, and do not splash the fertilizer on the branches and leaves. Usually 1 2 years to turn over the pot 1 times, mostly in early spring, mainly to change the soil and add decomposed organic fertilizer as base fertilizer. Under normal circumstances, camellia is not pruned, only diseased branches, weak branches, overly dense branches, and long branches need to be pruned.

1. Soil.

Potting soil is important for the growth and importance of camellia, so it is necessary to be cautious when choosing soil, usually with high humus content and slightly acidic soil, so as to meet its needs for soil.

2. Temperature. Camellia is afraid of high temperatures and low temperatures, so the temperature is best between 18 and 25 degrees, if the temperature is too high or too low, it will affect its growth, especially in winter, it is necessary to move it back to the room for maintenance, and when there is sun at noon, it can be moved to the balcony. In the summer, it is necessary to protect from exposure to the sun, and the temperature is too high.

3. Watering. Camellia loves moist places, so moisture is important to it, but make sure to water it in moderation, not too dry or too wet, otherwise it will affect root growth. If it is in summer, you can water more water to facilitate its growth, if it is winter, you need to reduce the amount of watering, once every 2 to 3 days to prevent frost damage.

4. Fertilization. Camellia likes fertilizer, so in the maintenance, the amount of fertilizer should be sufficient, especially in the growth period, in addition to adding fertilizer that is conducive to growth, it is also necessary to add potassium dihydrogen phosphate, which can promote its later flowers to be more colorful, but remember not to fertilize too much, otherwise it will affect the growth of roots.

5. Periodically. Pruning is also very important in maintenance, when it has too many buds, it needs to be pruned regularly, cut off the weak branches on the top, and tidy up the buds, so that it can better absorb nutrients.

2. Light: It has certain requirements for light, likes light, but can not bask in strong light, and it is easy to sunburn if exposed to strong light for a long time. So be sure not to put it in strong sunlight in the middle of summer.

3. Moisture: It prefers water, so it must ensure that there is enough water when breeding, but there can be no stagnant water in the pot, otherwise it is easy to cause its root system to rot.

4. Temperature: It is suitable for growing at a temperature of 18-25, and can withstand a certain amount of cold, but it is not heat-resistant, so it is necessary to pay attention to cooling and ventilation in summer, and keep it above 5 when the temperature is the lowest, so as to overwinter.

5. Precautions.

When the buds are blooming, if there are many flowers, cut off some of the buds so that the remaining buds will grow beautifully. When the weather is warm, it is easy to get sick, so you need to spray some medicine in advance to prevent it.

1. Light: When cultivating potted camellias, it is necessary to provide full sunshine for it, and it should be moved to the canopy in summer. 2. Water and fertilizer:

In spring, potted camellia should be watered once every 2-3 days, and phosphorus and potassium fertilizer should be provided for it. 3. Pruning: During the breeding period, the diseased and insect branches and excess flower buds of camellia should be cut off to reduce nutrient consumption.

1. Light temperature

Potted camellia is suitable for placing in a warm and moist, well-ventilated place to maintain, the sun in spring and autumn should be sufficient, and the summer should avoid direct light, you can put it under the canopy to breed, the most suitable for potted tea flowers to grow between 18-25, and the temperature in winter should be kept above 3.

2. Water and fertilizer management

Potted camellia can be watered more in spring, which is conducive to its germination and branching, in the morning and evening of summer to spray water on its foliage, it is best to water at noon in winter, and water every 2-3 days throughout the year, the base fertilizer of potted camellia is best to choose phosphorus and potassium fertilizer, and 2-3 times of thin fertilizer can be applied in April and May.

3. Prune and turn over the pot

The growth of potted camellia is relatively slow, so there is no need to prune excessively, only need to cut off diseased branches and excess flower buds, so as not to consume nutrients, you can turn the pot every 1-2 years, replace it with a larger pot, and add loose and fertile new soil, and change the pot is best carried out in April every year.

When raising camellias, you can mix humus soil, garden soil, and river sand to prepare soil, and let the plants receive sufficient light when breeding, but do a good job of shading when the light is strong. Camellia is a water-loving plant, when breeding to water the plant in time, the breeding process should change the soil for the plant every two years, and the soil should be light every time the soil is changed.

1. Prepare soil

Camellia, also known as camellia, belongs to the camellia family and is often planted as a family potted plant. Camellia is suitable for growing in moist, fertile and well-drained sandy loam soil, and can be mixed with humus, pastoral soil and river sand to prepare soil when breeding.

2. Sufficient light

Camellia is a sun-loving plant, it is best to plant the plant in an outdoor sunny environment, and the light is stronger in summer, so it is best to plant the plant in a semi-shaded and ventilated place. During summer farming, the plants can be exposed to light every morning and evening, and in case of rainy days, light lamps can be used instead of sunlight to irradiate the plants.

3. Watering in time

Camellia is suitable for growing in a warm, moist and ventilated environment, and has a high demand for water, so the plants can be watered according to the changes of the seasons when breeding. Spring and autumn are the growth period of camellias, and it is best to water the plants 1 2 times a week for planting; In summer, when temperatures are high, it is best to water the plants every two days.

Camellia grows faster, it is best to change the soil every two years according to the size of the plant when planting, and start lightly every time you change the soil, so as not to hurt the roots of the plant, and you can properly prune the roots of the plant when changing the soil. Changing the soil for camellia leaves half of the old soil, so that the plant can better adapt to the new soil.
