When does the Christmas tree grow new leaves?

When will the Christmas tree grow new leaves? Almost everyone will buy flowers and plants at home. Some people like to buy Christmas trees. When will it grow new leaves? Let me see when the Christmas tree will grow new leaves with you.

When will this tree grow new leaves? 1 As long as it is properly maintained, this tree can grow new leaves all year round. When breeding, the temperature should not be lower than 5℃ in winter, otherwise the bark is easy to freeze and crack, and the temperature should be controlled between 20-30℃. It is more resistant to shade and can be cultivated in semi-shade environment.

Causes and solutions of not sprouting new buds on safe trees

1, basin soil discomfort

When we were cultivating safety trees, because we didn't loosen the soil effectively for a long time, the soil in the basin was dry and not loose. The air in the basin soil is difficult to enter, and the roots can't breathe effectively, which leads to the phenomenon of no germination. There is also the fact that the pot has not been changed for a long time, and the soil in the pot has deteriorated, which will also prevent the tree from sprouting.

Solution: First of all, you need to loosen the soil for the safety tree regularly. Be careful not to hurt the root system when loosening the soil, and shovel lightly. Moreover, when the tree grows to a certain stage, it needs to be changed into pots, planted separately and replaced with new culture soil.

2, improper lighting

Christmas trees like a sunny environment. If it is placed in an opaque environment for a long time, it will not promote photosynthesis and will not grow, which will lead to signs that the Christmas tree will not sprout. Moreover, too strong light will burn the leaves, and improper germination will lead to yellowing.

Solution: In order to make it fully germinate, it is necessary to properly carry out sufficient lighting conditions, so as to effectively promote photosynthesis, and its roots fully absorb sunlight and promote the germination of safe trees. If the light is strong, shade it properly and move it to a cool and ventilated place.

3. Improper fertilization

When we fertilize the safe tree, if we fertilize it too much, it will cause fertilizer damage to the plant and lead to the phenomenon of no germination. If too little fertilizer is applied, the plant will lack nutrition, so there will be no new shoots. Another kind is thick fat or raw fat, which will not germinate.

When will this tree grow new leaves? 2 1. Choose the soil for this tree.

The potted plants of Christmas trees should use loose and fertile acid soil with good drainage and rich organic matter. Heavy soil hardening or insufficient acidity, poor drainage and basin soil hardening may all lead to fibrous root rot, yellowing of plant leaves and poor growth. Can be cultivated in humus soil. Small factories change a pot every year, while large factories change a pot every 2-3 years on average.

2. A watering method for safe tree cultivation

Peace trees like humidity, so they should be watered when the soil surface is half dry, and sprayed frequently or on the leaves when the weather is dry. Wait until the soil in the basin is half dry before watering it in winter.

Christmas trees like environments with high air humidity, usually relative humidity. If it is more than 80%, it will thrive. In summer or dry autumn, even in winter, if you put it indoors, you should always spray water on the leaves to create a relatively humid space environment. If there is water in the basin, it is easy to cause root rot.

3. A fertilization method for safe seedling raising.

Ping 'an tree likes fertilizer, and it can be topdressing with compound quick-acting fertilizer once a month in the growing season and 1 ~ 2 times after autumn to increase the cold resistance of Ping 'an tree plants. Excessive application of chemical fertilizers, including raw fertilizer, concentrated fertilizer and large fertilizer, will burn and necrosis its fine fibrous roots, leading to yellowing and falling off of leaves. The plant of Ping An Tree can be detached from the flowerpot, and its root system can be carefully checked for rotten roots.

If the fibrous roots turn brown and black with peculiar smell, which proves that the roots are rotten, the rotten fine roots can be cut off first until the fresh fine roots are cut off. At the same time, cut off some branches and leaves, plant them in clean and fresh loose sandy loam soil, change watering to water spraying, keep the basin soil moist, and plant them in fertile culture soil after better roots are born.

From spring to autumn, a small amount of N: P: K = 2: 1: 1 compound fertilizer granules 1 time is applied every month, and fertilization is stopped when the temperature is low in winter.

4. Temperature requirements for safe tree reproduction

The suitable temperature for the growth of Pingan tree is 20 ~ 30℃, and its cold resistance is weak, so it can't stand the low temperature below 0℃, otherwise it will easily lead to the bark freezing and cracking, the branches and leaves withering, and the young trees will freeze to death by the roots. Family potted plants should be wintered at room temperature around 10℃ to keep the trees green all the time.

5. Lighting requirements for safe tree reproduction

The light demand of Christmas tree changes with age. When the shade tolerance is young, 3-5-year-old plants grow faster in the shade; 6 ~ 10 annual plants need sufficient sunshine. Potted plants should not be given full light after entering summer. They can be placed in the shade of trees or under shade sheds, and give about 50% scattered light. If they are fully exposed to light in the morning and evening, their growth will be ideal. If the light is too strong, it will easily cause the leaves to turn yellow, which will affect the viewing effect.

6. Four seasons management of safe tree breeding

(1) spring management

Potted safe trees should leave the house around Tomb-Sweeping Day in spring, but after leaving the house, we should still pay attention to prevent the cold damage that may be caused by late frost or late spring cold. In late spring and early summer, it is best to shade about 30%, keep the basin soil moist without water, and the relative humidity of the air should be above 80%.

In addition to fertile soil and sufficient base fertilizer, potted Pingan trees can be topdressing 1 time every month from mid-spring to early autumn. Anthracnose and brown spot are easy to occur in spring, which can be prevented by using 1% bordeaux mixture, and a small amount of diseased leaves can be removed and burned in time.

(2) Summer management

In summer, potted trees need 40% ~ 60% shade under high temperature and strong light. If the light is too strong, it will easily cause the leaves to turn yellow and reduce the ornamental value. Especially for potted plants that have been placed indoors for a long time, when they are moved outdoors for restorative maintenance in summer, they must be cautious and gradually increase the light, so they must not be rushed, otherwise they will easily cause leaf burns. When the temperature exceeds 32℃, it is necessary to regularly spray water on the leaves and their surroundings for humidification and cooling, so as to keep them growing vigorously. Top dressing with dilute liquid fertilizer or compound fertilizer 1 time per month. In summer, leaf roller moths are frequent and can be sprayed with pyrethrins.

(3) Autumn management

After autumn, the temperature drops gradually. The potted safety trees should be watered in a controlled way, gradually reduce the amount of watering, and often spray water on the leaves and their surroundings to humidify them. Drainage should be done in time after rain to avoid water accumulation in the basin, which will lead to yellowing and peeling of leaves and even death of rotten roots. Before cooling in autumn, 0.2% ~ 0.3% potassium dihydrogen phosphate solution should be sprayed twice continuously to increase the cold resistance of plants, promote the early lignification of tender shoots and ensure safe overwintering.

Seeding method is often used for Christmas tree seedling, and the suitable period is from September to autumn 10. Mature purple-black fruits can be used for sowing. After washing the peel and pulp, float the seeds to remove the empty seeds and dry them in the shade. Seeds can be picked and sown at the same time. Before sowing, soak them in warm water of about 40℃ for 30 minutes, or sow them in wet sand to accelerate germination and germinate after 20 ~ 30 days. When the seedlings grow 3 ~ 4 true leaves, topdressing liquid fertilizer 1 time every month, stopping fertilization after autumn, and keeping the temperature not lower than 5℃ to ensure safe overwintering.

(4) Winter management

The young trees of Pingan tree are not tolerant to low temperature and need to be domesticated in time. The overwintering temperature shall not be lower than 5℃. If the plants maintained or cultivated in the open field are frozen for more than 5 days, it is easy to cause bark cracking, branches and leaves withering, and even the whole plant freezing to death. Larger plants can tolerate a low temperature of about 0℃ for a short time. In winter, watering should be controlled, the soil should be kept dry, and various forms of topdressing should be stopped, so as not to damage the roots of fertilizers, lead to yellowing of leaves or withered leaves, and make it difficult to restore the original appearance of plants.

When will this tree grow new leaves? 3 cultivation methods and matters needing attention of this tree.

1. Breeding method:

1. Lighting: Sufficient sunshine is beneficial to the growth of Christmas trees. However, it should be noted that the requirement of Christmas tree for sunshine is generally bright astigmatism, so direct sunlight should be avoided in summer and strengthened in autumn and winter.

2. Temperature: The most suitable growth temperature of the Christmas tree is between 20 and 30 degrees, but as long as the temperature is not lower than 5 degrees and not higher than 30 degrees, there is generally no big problem. But if it is lower than 5 degrees and higher than 30 degrees, it will cause frostbite and slow growth of the Christmas tree.

3. Moisture: Ping An Tree is drought-tolerant, so don't water it too often, but water it thoroughly, and the next watering should be based on drying the soil. In this way, it is not easy to cause water accumulation in the basin soil, which leads to the root rot of the safety tree.

4. Soil: Ping An Tree has the same requirements for potted soil as most plants, as long as the soil has certain air permeability and drainage, and it is also slightly acidic soil or neutral soil rich in organic matter.

Second, matters needing attention:

1. If the safety tree is cultivated outdoors, it should be moved indoors in rainy season to avoid root rot caused by accumulated water in the basin.

2. If the leaves of the safety tree are yellow, the yellow leaves should be removed in time, and plants should be planted to keep the surrounding air circulating.

Generally, we should change the pot soil for the Christmas tree once every year or two. When changing soil, clean the flowerpot and trim the broken root system.
