How to cultivate Cunninghamia lanceolata culture methods and matters needing attention

Speaking of southern fir, I believe everyone is more familiar with it, because it is more common in our life, whether in the park or in the room can see its figure. Cunninghamia lanceolata has high ornamental value and is deeply loved by everyone, so do you know how to cultivate it correctly? Let's discuss the correct maintenance methods of Sequoia chinensis with the editor.

How to raise Sequoia fortunei

1. Soil: Cunninghamia lanceolata is cultivated in Guangdong, Fujian, Hainan, Yunnan and Guangxi, while the Yangtze River valley and its northern cities are potted and overwintered in greenhouse. It is most suitable to prepare rotten leaf soil, garden soil and river sand with rotten leaf soil, garden soil and river sand.

2. Watering: Cunninghamia lanceolata likes the humid environment, so we should pay attention to spraying clear water to the leaves in dry season and summer, which can not only increase the air humidity, but also keep the leaf color fresh and bright, which is very beneficial to its photosynthesis. Watering should be appropriate during maintenance and adequate in summer to supplement the need for foliar transpiration in time and avoid drought damage. But watering can not be excessive, so that the basin soil stagnant water, usually in order to keep the basin soil often moist.

3, light: Nanyang Shanxi has plenty of sunshine, the northern area generally moves to the south balcony or courtyard sunny place in early May, pay attention to proper shade after summer to avoid exposure. Farming in the north will be moved indoors at the end of September and the beginning of October, where there is plenty of sunshine, and watering should be controlled.

4. Temperature: Cunninghamia lanceolata prefers warm and humid climate, does not tolerate drought and cold, and can grow at many different temperatures, but the cold tolerance is not strong. The optimum temperature for growth is 724 ℃. If the temperature increases, it will increase the air humidity around the plant.

5. Fertilization: Cunninghamia lanceolata grows rapidly, so in its vigorous growth season, topdressing is often needed to supplement the nutrients needed for its growth. Generally, from the time of new bud germination in spring, we should pay attention to topdressing rotten thin cake fertilizer and water twice a month for its absorption and utilization in order to grow healthily.

6. Pruning: the lower branches and leaves of Cunninghamia lanceolata are easy to wither and yellow and fall off gradually, which causes the whole plant to be top-heavy and beautiful, so it should be carefully managed and pruned as necessary.

Culture method of Cryptomeria fortunei

1. Lighting

Cunninghamia lanceolata likes the sunny growth environment and likes the sun, but the seedlings like the shade, which needs plenty of sunshine in winter and shade properly in summer to avoid sun exposure.

2. Temperature

Cunninghamia lanceolata likes a warm and humid climate, is not cold-resistant, and grows best when the temperature is maintained at 25 ℃-30 ℃. Indoor pot culture should be kept in a well-ventilated place and the room temperature should not be lower than 8 ℃.

3. Soil

Cunninghamia lanceolata likes the fertile soil. Pot culture requires loose and fertile soil with high humus content and strong drainage and breathability. it is better to mix 3 parts of loam, 1 part of rotten leaf soil, 1 part of coarse sand and a small amount of plant ash. The depth of the soil layer lies in the bud point of the upper rooting just exposed on the soil surface.

4. Watering

It is usually necessary to keep the relative humidity in the air above 70%. Watering frequently during the growing season, about 3 times a week, the best depth of watering is 10ml 15cm. With the growth of Cunninghamia lanceolata, the frequency of watering is gradually reduced, and the basin soil and the surrounding environment are often kept moist.

Matters needing attention of Cryptomeria fortunei

1. Young trees change pots frequently. The young trees of Cunninghamia lanceolata had better change their pots every year or every spring, and the plants that have been more than five years had better change the pots and turn the soil every two or three years.

2. Keep the environment humid. Cunninghamia lanceolata is not resistant to drought, so in the season of high temperature and drought, we should often spray water and spray on and around the leaves to increase air humidity and keep the soil moist. Do not basin soil too dry or too wet, it is easy to cause the softening of the lower leaves.

3. Apply fertilizer frequently. Potted Cunninghamia lanceolata should be mixed with rotten leaf soil, peat soil, pure river sand and a small amount of mature organic fertilizer. When new buds sprout in spring, rarefied organic liquid fertilizer and calcium fertilizer should be applied twice a month to keep the leaf color moist.

Growth habit

Cunninghamia lanceolata, like light, seedlings like shade. Like warm and humid climate, not resistant to drought and cold. I like the fertile soil. It has fast growth, strong sprouting ability and strong wind resistance.

It needs plenty of sunshine in winter, avoids strong light exposure in summer, and is afraid of the dry gale in spring in the north and the hot sun in midsummer. It grows best under the environmental conditions of 25 ℃-30 ℃ temperature and 70% relative humidity. Pot culture requires loose and fertile soil with high humus content and strong drainage and air permeability.

As mentioned above, Cunninghamia lanceolata is one of the five largest park tree species in the world, which is planted in a large area all over the country, and it is the most common in general parks. In fact, Nanyang fir as a potted plant is also very elegant, potted plants will be relatively smaller and more exquisite, placed in the office area or room are very beautiful oh!
