How to grow potted camellias? Master the care methods and precautions, including keeping watering generous

Camellia is surely familiar to everyone; it is one of China's top ten famous flowers, and its beautiful blooms and vivid flower colors are deeply loved by flower enthusiasts. In daily life, many people want to grow camellias, but many of them do not know how to care for them. For this reason, the editor has carefully compiled the cultivation methods and precautions for camellias. Friends who want to grow them should definitely take a look~

1. How to grow camellias: create the environment

The beauty of the camellia is beyond doubt, and anyone who has seen it will fall in love with it. As for how to grow camellias, you need to create the most favorable environment for them according to their growth habits. For this reason, the editor will explain in detail the cultivation methods and precautions for camellias from the aspects of soil, light, temperature, watering, fertilizing, and so on. Let's continue reading below.

2. Cultivation methods and precautions for potted camellias

1. Soil: slightly acidic

When growing potted camellias, soil is the first thing to consider. According to the growth habits of camellias, we should choose loose, fertile, well-drained, slightly acidic soil. Note: never use calcareous soil. Soil selection: generally use black soil, red soil, pine needle soil, and sandy soil, mixed and stirred to prepare nutrient soil.

2. Temperature: 18-25°C

In the cultivation methods and precautions for camellias, temperature is a point that people easily overlook but is very important. If you want camellias to grow well, it is best to keep them in an environment of 18-25°C, and move them indoors for cultivation in winter.

Precautions: If the ambient temperature is too high or too low, it is not conducive to the growth of camellias. A temperature above 35°C will cause leaf scorch, leading to symptoms of yellowing camellia leaves; in winter, keep the temperature at 3-5°C, and it must not exceed 16°C, otherwise it will promote sprouting and cause leaf drop.

3. Light

It is understood that camellias are semi-shade flowers, so their light requirements are not high, but appropriate light is still very necessary. During the flower bud differentiation stage, the whole camellia plant should gradually receive sufficient photosynthesis; in summer, a shade frame should be set up.

Precautions: Although camellias do not need too much light, in winter, if there is too little light, it will lead to insufficient photosynthetic supplementation, resulting in poor growth of camellias and the appearance of disease symptoms.

4. Watering

When it comes to how to grow camellias, watering is naturally indispensable. It is understood that camellias like a moist environment, so water frequently, but do not let the soil become too wet. In spring and summer, we should water camellias more, 1-2 times a day, in the morning and evening; in winter, reduce watering, and watering once every two to three days is best.

Precautions: Although camellias like water, do not spray water on the flowers when watering, otherwise it will cause the flowers to rot and shorten the flowering period.

5. Fertilizing

After watering, let's talk about fertilizing, which is also very important in the cultivation methods and precautions for camellias. Camellias like fertilizer. In autumn and winter, because flower buds develop quickly, apply a diluted liquid fertilizer once a week after full decomposition, and apply 1 to 2 additional applications of phosphorus and potassium fertilizer; after sprouting in spring, apply a light fertilizer solution once every 17 days; in summer, apply phosphorus and potassium fertilizer; in early autumn, fertilizer can be stopped for about 1 month.

Precautions: Although camellias like fertilizer, too much fertilizer should not be applied. Excessive nitrogen fertilizer can easily cause flower buds to scorch and wither, and after flowering, less or no fertilizer can be applied.

6. Pruning

In the cultivation methods and precautions for camellias, regular pruning of flowering branches is something everyone should pay attention to. Generally, when the camellia flower buds are dense, cut off weak branches and thin out the flower buds, which can also promote the camellia's absorption of nutrients.

7. Pests and diseases

During the cultivation of camellias, if you are not careful, they are prone to pests and diseases. Generally, there are two diseases: black mold and anthracnose. As for what medicine to spray, it is introduced in detail in the pest and disease control of camellias, so it will not be discussed much here.

3. How to grow camellias so they grow well

In the process of cultivating camellias, many people actually grow them according to the requirements, but after all, we are not professionals and often have no time to care for them, which leads to problems. So how to grow camellias well is very simple: if everyone follows the above requirements and does everything properly, they will naturally grow very vigorously, and vice versa.

1. Cultivation methods for potted camellias

1. Pot soil selection:According to the growth characteristics of camellias, a slightly acidic, loose, fertile, well-drained mixed soil should be selected as the pot soil. Special attention should be paid to good drainage, and calcareous soil must be avoided. The proportion of the mixed soil is 6 parts red soil, 3 parts orchid mud (leaf mold), and 1-2 parts fine sandy soil. The pot size should be moderate, not too large or too small. Generally, the ratio of pot to seedling is that a camellia plant 40-50 cm tall with a crown width of 20-25 cm is suitable for planting in a purple clay pot or tile pot with a diameter of about 20 cm, and other sizes can be inferred accordingly.

2. Potting time:The potting time for camellias is November in winter and February-March in early spring. At this time, the flower buds are plump and the flowers are in full bloom, making it the most suitable time for potting. When the flowers are fading and new roots are still germinating, if potting is needed, special care must be taken not to damage the root system. Generally, potting should be stopped before and after the budding stage, because at this time new shoots are about to emerge and leaves are unfolding, requiring a large amount of water. If potting is carried out, the new roots will be injured, which can easily affect the growth and development of that year. Potting is also taboo in high-temperature and severe winter seasons, so as to avoid causing the plant to shrivel and die.

3. Potting method:First place 3-4 pieces of broken tile over the drainage hole at the bottom of the selected flower pot, then fill in some coarse soil, plant the seedling in the pot, fill the root area with fine soil, and then slowly place larger particles of pot soil around the pot, gently shake the pot, and press with your hand so that the pot soil fits tightly against the roots. For large pots, a bamboo stick can be used to gently press the pot soil downward, taking care not to damage the roots. The pot soil should account for 4/5 of the pot height to facilitate watering.

4. Watering method:Newly potted seedlings should be kept moist. After 2 months, they can be watered like other potted seedlings. The frequency of watering should depend on climatic conditions, with the principle of keeping the soil moist. Generally, more watering can be done in spring to meet the needs of sprouting and shoot growth. In summer, watering should be done in the morning and evening. During the plum rain period, water accumulation should be prevented. In autumn drought, water should be given in time. In winter, watering should be done at noon to prevent the pot soil from freezing, as dry soil freezes even more severely.

5. Fertilizing method:Camellias do not particularly like fertilizer, so there is no need to apply too much. Generally, fertilize 2-4 times before flowering in October-November and after flowering around April-May. Generally, a mixed fertilizer is used (human manure and urine, cake fertilizer, barnyard manure, phosphate fertilizer), preferably mainly phosphorus fertilizer with nitrogen fertilizer as a supplement, to prevent excessive vegetative growth of branches and a reduction in flowers. All kinds of fertilizers must be fully decomposed before use, but rapeseed cake and fish meal can be directly scattered on the soil surface without decomposition, covered with a thin layer of soil, and left to slowly decompose and seep into the soil for root absorption. The amount of fertilizer applied should be controlled by applying more to strong seedlings and less or none to weak seedlings. For seedlings that are too weak, replacing the pot soil instead of fertilizing also has a very good effect.

6. Shading and cold protection:Camellias naturally prefer a warm and humid climate, and both too cold and too hot are unfavorable to growth and development. In spring and the plum rain period, potted camellias should be given sufficient sunlight; otherwise, the branches will develop thinly and weakly, making them prone to sooty mold and scale insect damage, or moss growing on the trunk, leading to dead branches, aging, or death. In the high-temperature seasons of summer and autumn, shade and cooling should be provided in time. If the winter temperature drops below zero, it will cause flower buds to fall off or flower centers to freeze, affecting flowering quality. Therefore, the indoor overwintering temperature for potted seedlings should preferably be kept at about 3-4°C. If the temperature exceeds 16°C, it will promote early sprouting and, in severe cases, cause leaf drop and bud drop.

7. Disease control:The main pests of camellias are stem borers and scale insects. The main diseases include anthracnose and black sooty mold on the leaves, as well as moss parasitism on the branches and trunk. Affected branches should be cut off in time and pesticides should be sprayed for control.

2. Precautions for cultivating camellias

1. Camellias should not be heavily pruned. Their flowers, leaves, and buds develop over a relatively long time, and the crown also forms relatively evenly. Basically, no special pruning is needed; it is enough to cut off diseased and pest-infested branches, overly dense branches, and weak branches, and to shorten excessively long branches.

2. Camellias are a multi-flowered tree species. Especially on weak-growing plants, if the flower buds are dense, they will consume too many nutrients, which is unfavorable to plant growth. Therefore, bud thinning is an important part of cultivation management. It is best to keep 1-2 buds per branch, with at most only 3, and maintain a certain distance. The thinned flower buds can be used medicinally.

3. Camellias have a relatively long flowering period, with the entire flowering period lasting up to half a year. Therefore, promptly removing flowers that are near withering is very beneficial for reducing nutrient consumption and strengthening the tree's vigor.

[Editor's Conclusion]Camellias like a warm, humid, and well-ventilated environment, and special attention must be paid during care. The above has introduced the cultivation methods and precautions for potted camellias. Does everyone understand them now?

How to grow potted camellias? Cultivation methods and precautions for camellias

Camellia is a flowering plant of the genus Camellia in the family Theaceae. Its leaves are green and distinctive, and its flowers are large and colorful. It has very high ornamental value and is an excellent potted ornamental flower, deeply favored by flower and plant lovers. So, how to grow potted camellias? The cultivation methods and precautions for camellias are introduced below.

1. Cultivation methods for potted camellias

1. Placement location:Camellias like semi-shade and avoid scorching sun, and are suitable for placement in a warm, humid, ventilated, and light-transmitting place. When cultivating camellias, there should be sufficient light in spring. In summer, attention should be paid to shading and avoiding direct sunlight. If camellias are placed on a balcony, they will often be sunburned to death if one is not careful. During storage and transportation of camellias, high temperatures and dry air must be prevented; otherwise, flower buds and flowers are likely to fall off, affecting quality.

2. Temperature:Camellias naturally prefer a warm climate. The suitable growth temperature is between 18-25°C, the initial flowering temperature is 2°C, and they are slightly cold-tolerant. General varieties can tolerate a low temperature of -10°C, and they can also tolerate summer heat, but above 36°C will inhibit their growth. Cultivating camellias requires a certain temperature difference, and the best environmental humidity is above 60%. In areas south of the Huaihe River, they can generally overwinter naturally, while the Yunnan camellia varieties among camellias are slightly less cold-tolerant.

3. Watering:When cultivating camellia bonsai, the soil should be kept moist, but not waterlogged, so as to avoid alternating dry and wet conditions affecting growth. Generally, in spring, appropriate more watering is beneficial for sprouting and shoot growth; in summer, insist on watering in the morning and evening, preferably spraying water on the leaf surface to make the leaves thoroughly wet. Do not water with hot water, and watering should avoid the high temperatures around noon; in autumn, watering should be moderate; in winter, watering should preferably be done around noon, and spraying water once every two or three days is sufficient.

4. Fertilizing:Camellias like fertilizer. When potting, attention should be paid to placing a layer of base fertilizer in the pot soil, mainly phosphorus and potassium fertilizer. The best fertilizer is a mixture of decomposed bone meal, hair, chicken feathers, rice husk ash, poultry manure, and superphosphate. Usually, too much fertilizer should not be applied. Generally, apply 2-3 times of diluted fertilizer solution after flowering between April and May, and apply one slightly stronger water-soluble fertilizer in November in autumn. When fertilizing camellias, note that the proportion of phosphorus fertilizer should be slightly larger to promote abundant flowers and vivid colors.

5. Pruning:Camellias grow relatively slowly and should not be pruned excessively. Generally, it is enough to cut off excessively long branches, diseased and pest-infested branches, and weak branches. If there are too many flower buds on each branch, thin the flowers, keeping only 1-2 and maintaining a certain distance, while the rest should be removed early to avoid consuming too many nutrients. In addition, promptly remove flowers that are about to wither, which can also reduce nutrient consumption, helping camellias grow robustly and form new flower buds.

6. Repotting:Potted camellias are best repotted once every 1-2 years. The new pot must be one size larger than the old pot, which is beneficial for the camellia root system to spread and develop. The best time to repot camellias is in April in spring, though it can also be done in autumn. When repotting, combine it with changing the soil by appropriately removing part of the compacted old soil, replacing it with fertile, loose, breathable new culture soil, and first placing a layer of base fertilizer.
