Camellia, scientific name "Apocynum venetum", is white and lovely, and is deeply loved by everyone. The following is the related content about tea cultivation methods and matters needing attention, which I hope will help you.

Cultivation method of camellia Camellia is a kind of sunny flower, with long sunshine, hot and humid, and cold. It needs to be above 5℃ in winter to overwinter safely. The suitable growth temperature of jasmine is 25℃? 5℃。 According to the requirements of jasmine on temperature, humidity and lighting conditions, its summer and autumn maintenance methods are as follows.

When the tea leaves are in full bloom, pay attention to keep the soil moist and water it 1 every day. Three times. This kind of flower likes fertilizer, and it should be applied with decomposed dilute liquid fertilizer every three to five days, or mixed with a small amount of dilute liquid fertilizer when watering. Fermented bean cake water, rice washing water and fishy water can be used as topdressing. You can also bury the cooked soybeans in the pot for topdressing to increase the amount of water. If the pot soil is hardened, loosen it. In autumn, as the weather gets colder, the amount of watering should be appropriately reduced and fertilization should be gradually stopped. Before the outdoor minimum temperature drops to 5℃, move potted flowers into indoor sunlight.

When entering the room for the first time, be sure to open the window for ventilation and control watering. Hua Yan said:? Jasmine is not pruned, which is obviously weak branches and few flowers. Do you need a monkey to trim the flowers? . Some people tend to pay more attention to fertilizer and water, ignoring pruning, and even reluctant to cut off the dead branches and old leaves after wintering, resulting in thin branches, small leaves, ugly plant types and poor flowers. In fact, in addition to fertilization, watering and sunbathing, potted jasmine must be pruned in time. As long as it is trimmed properly, it can make branches strong, leaves big and flowers many.

The pruning of tea flowers is not only important in spring, but also in summer, except for pruning most delicate branches after wintering, leaving only a strong base for new buds to germinate. The branches after flower decay should be observed in time. Section 5, cut off the top to promote the germination of its new branches and keep the flowers flourishing. Otherwise, a small number of secondary branches germinate at the top of the old branches, with few flowers and fine flowers. At the same time, in summer, the slender and even branches that jasmine often germinate consume nutrients, so they should be cut short in time, leaving 1? 2 leaf nodes. In this way, powerful flowers will sprout from the branches and leaves, and then combined with pruning, the delicate branches on the two pairs of leaves and the third pair of leaves at the end of the branches will be cut off, so that the plants will be suitable in height, symmetrical and beautiful. Then take off all the old leaves, don't hurt them when picking them, and be careful not to pick them too wet. Pruning and picking leaves can promote the growth of new buds and more pregnant buds. In order to make its branches flourish, when the spring shoots grow to 4? In the fifth section, we should also be careful. In the future, not only will it cost more, but the plant type will also be full. For branches without buds, two pairs of thin leaves at the top should also be picked to facilitate growth and flowering.

Precautions for tea culture 1. Lighting conditions. Camellia should avoid strong light. When planting, we must pay attention to the sun. In spring and autumn, we need sufficient light, but we must avoid direct sunlight in summer. Camellia will die easily as long as it is exposed to strong light for too long, and it is best to transplant it under the shed if possible.

Second, pay attention to the temperature. Camellia is neither cold-resistant nor heat-resistant. Its optimum temperature is 18-25 degrees, so it is required that the ambient temperature should not be too high or too low, otherwise it will affect its growth, especially in winter. The indoor temperature must be above 3 degrees, and frostbite will occur below 0 degrees.

Third, watering matters, camellia likes humid environment, so we must pay special attention. Not too dry, not too wet, and not too wet when dry. Generally, you can water more in spring, which is conducive to germination. Water twice in the morning and evening in summer, and it is best to water the leaves when it is hot. It is forbidden to water the arc when the plants are hot, just like autumn and spring, but it is best to water them before and after the plants, not every day.

Fourth, the main points of fertilization, camellia likes fertilizer, so special attention should be paid to the application of fertilizer in the whole breeding process, such as adding phosphorus and potassium fertilizer to the upper pot, but fertilization is limited and must not be too much. Generally, it only needs to be fertilized about three times within six months after flowering, and once in winter. In order to make the flowers more beautiful, it is better to put more phosphate fertilizer in the fertilizer.

Fifth, pruning. Pruning camellia is very important. Generally, cut off the branches that affect the tree shape and the weak branches, and arrange the buds. Once the buds are too dense, they should be combed and picked in time after the flowers wither, which can reduce the consumption of nutrients.

Sixth, camellia turns over the pot, and many people will ignore it. Many people don't turn over the pot after going down. Actually, this is very wrong. Camellia usually turns the pot once every two years, so it needs to be changed into a big pot, which is beneficial to its growth. Pay special attention to the time to turn over the pot, preferably in April. Pay attention to the steps when turning the pot. Don't remove all the old soil and add a small amount of base fertilizer.

Seventh, pest control, camellia is easy to get sick. There are two common diseases, black mold and anthracnose. At this time, only 0.5-degree Bordeaux mixture needs to be sprayed, and the pests of camellia are mainly tea-tip moths. At this time, it is enough to cut off the insect tip.

Eighth, soil requirements: soil is the foundation of camellia growth, and all the nutrients of camellia are obtained from soil, so the requirements for soil are quite high. Generally, its soil contains high humus, PH value is 5-6.5, and it is slightly acidic. The best soil configuration is: mountain soil 50%, sawdust or edible fungus residue 40%, cake fertilizer powder or livestock manure and phosphate fertilizer powder 65,438+00%.

Ninth, air circulation, the place where camellia grows requires extremely high air circulation, which is most suitable for growing in the breeze. However, camellia is very afraid of northwest wind and strong wind, because northwest wind and strong wind easily evaporate water too quickly, and the supply and demand of camellia are out of balance, which is not conducive to the growth of camellia.
