The whole African overlord tree is a small potted plant. How do you raise this thing?

The African overlord tree is native to the southwestern part of the island of Madagascar, in the oleander family, and in the genus Hammer tree.

The African overlord tree grows quickly, so small seedlings should be planted in large pots. The African king tree is strong and strong, and it is necessary to use peat, perlite, and coarse sand in daily cultivation according to 12:1:

The ratio of 2 is to prepare the culture soil, and the moisture is suitable for seeing dry and wet. Except for the summer seedlings with a little shade, full sun management should be carried out. In its entire growth cycle, it is necessary to ensure that the fertilizer and water are sufficient, and the seedling stage is nitrogen:

Phosphorus:Potassium 1:1:

1 ratio, poured once every half month; After the seedlings, press nitrogen:phosphorus:potassium 1 2:

0 8:1, poured every 10 days.

There are two main diseases of the African king tree: 1 Neck rot: mainly occurs after repotting and in poorly drained pots.

Therefore, it is necessary to pay attention to reduce damage when changing pots, and at the same time avoid overwatering too often. 2. Blight: Yellow spots first appear on the tips of young leaves, and then the color turns brown, black, and deformed, and the whole leaf dries up and falls off in severe cases.

The main reason is that the ratio of nitrogen, phosphorus and potassium is out of balance, and the growth is too vigorous. Therefore, it is necessary to prepare a good ratio of liquid fertilizer, and at the same time pay attention to drug prevention and control in the early stage of the disease, especially in rainy days: spray 800 times of manganese zinc or 1000 times of methyl tobuzin and 800 times of carbendazim.

There are fewer insect pests in the African overlord tree, only in spring and autumn, there are noctuidae in the heart of the young leaves, which can be controlled with dichlorvos 1500 times or pyrethrin 2000 times.

The main thing is to have plenty of sunshine.

It will grow very large, so it is recommended that you change to a large pot.

The brownish-green cylindrical stem of the African overlord tree is large and straight, and it looks like an oversized mallet, from which its genus name is derived; The dense 3 clusters of stubby and stubby hard thorns look like a kind of weapon in ancient China - mace; The top of the stem is clustered with linear leaves, emerald green, petioles and veins pale green; It has white flowers and has a long flowering period. The African overlord tree prefers warm, sunny, hot and humid environments, and is also drought tolerant. It can be sown and tillered for propagation.

The African overlord tree is tall, up to 6 meters high, and full of thorns, in the African desert with a wide field of vision, from a distance, it is full of domineering, and there is a kind of arrogant momentum. It has a peculiar appearance and can be used as a potted plant, and it is said that it has the effect of making the villains around you shy away. The African overlord tree is a rare species of succulents, and is one of the most ornamental species among about 25 species of the genus Hammer in the world.

It likes warmth and sunshine, and is drought tolerant.

The African king tree is mainly propagated by seeds. Its seeds are about 1 cm long and cm wide, mallet-shaped, grayish-white. It is advisable to sow in April and May, with a row spacing of more than 2 cm, a temperature between 18 and 25, and a humidity of more than 95%.

The sowing soil is mixed with peat, perlite and coarse sand in a ratio of 8:1:1, and after sowing, it is covered with fine peat, and it can be covered tightly, and germination can occur after 5 to 7 days.

The seedlings that have just sprouted should be given 50% shade, and the full sunshine management can be carried out after half a month, and the seedbed soil should be kept moist and aerated during the seedlings. One month after the emergence of seedlings, depending on the growth situation, the seedlings were refined to enhance resistance.

Pest control Sometimes stem rot damage occurs, and it can be sprayed with 10% antibacterial agent 401 acetic acid solution 1000 times. The insect pest has scale insect damage, and it is sprayed with 1000 times of 50% dichlorvos emulsifiable concentrate.

Sowing and dividing propagation.

Specific method: let the seedbed fully dry (generally about 3 days), water it again, add some fungicides when watering, such as dixone, methyl tobuzin, etc., and repeat twice. Three or four months after the emergence of seedlings, the seedlings are about 20 cm tall and should be repotted to facilitate their growth.

When repotting, be careful to reduce root damage and avoid pinching the root neck, which is most likely to be injured and cause plant rot. The African overlord tree grows quickly, so small seedlings should be planted in large pots. The African overlord tree is strong and strong, and peat and perlite and coarse sand should be used in daily cultivation according to 12:

The ratio of 1:2 is used to prepare the culture soil, and the water is suitable for dry and wet. Except for the summer seedlings with a little shade, full sun management should be carried out.

In its entire growth cycle to ensure that the fertilizer and water are sufficient, the seedling stage according to the ratio of nitrogen, phosphorus and potassium = 1:1:1, watered once every half a month; After the seedlings are grown, press nitrogen, phosphorus, potassium = ::

1. Water every 10 days.

<>1. Light: It is very important to supplement light, especially in the growing season, it is necessary to ensure that there is enough sunlight, and put it indoors by the sunny window in winter.

2. Water and fertilizer: There is no need to apply too much water and fertilizer, just give it according to the state of growth, and the appropriate amount of ants can be buried in the wild to prevent damage to the roots.

3. Temperature: It likes the warm growth environment of the warm ridge, which can withstand high temperatures, but can not withstand the cold, so it is properly ventilated and cooled in summer, and moved to the indoor to keep warm in winter.

1.First, it is necessary to maintain the overlord tree in a warm and dry environment, and control its growth temperature at around 25 degrees Celsius, with the lowest temperature in winter not lower than 15 degrees Celsius and the summer temperature not exceeding 35 degrees.

2.Second, it is necessary to choose sandy soil with good drainage for the overlord tree to maintain, and keep its potting soil slightly moist and not waterlogged.

3.Third, in the growing season of the overlord tree, it is necessary to use a slow-release compound fertilizer once a month.

Overlord tree likes warm, dry, hot and sunny environment, is not cold-tolerant, high-temperature resistant, and slightly resistant to semi-shade, avoid stagnant water. The growth of the temperature is 20 to 25, the room temperature in winter should not be less than 15, if the summer temperature exceeds 35, the leaves are easy to wither and fall off, and the winter temperature is below 10, susceptible to cold damage and frost damage.

For frozen ground plants, they can be partially removed after leaving the room in early April, and the plants can be repotted, and the cultivation soil is required to be loose and fertile, well-drained sandy loam.

If your frozen plant is not very tall and it is not suitable to cut the stem and cut cuttings at present, you can strengthen water and fertilizer management after repotting.

When the new leaves grow, keep the potting soil moist to avoid the potting soil being too wet, check the potting soil before each watering, and wait for the surface of the potting soil to dry before giving supplementary watering.

In the growing season, once a month to water potted flowers special fertilizer, can also be sprinkled with a small amount of multiple slow-release compound fertilizer particles, if the temperature is too high in summer, it is easy to cause its leaves to fall off into a semi-dormant state, at this time should control watering, keep the potting soil properly dry, and pay attention to shade and ventilation.

Winter temperature is lower than 10, will also cause leaf fall, cause plants to hibernation, if the shed temperature is too low, will cause the plant to freeze to death, winter is best to maintain more than 10 greenhouse temperature, maintain the pot soil slightly moist can wipe out the limbs.

(1) Temperature: It likes warmth, and the most suitable temperature for growth is 20 25 ° or less, and the leaves fall off; Freeze damage occurs below 0°C. It is resistant to high temperatures, but the leaves will turn yellow and fall off when above 35°C.

Kodo's cold resistance is slightly poor, and it is best to maintain a wintering temperature of more than 12°C. Because Guangtang is native to the dry summer and rainy winter areas of southwest Africa, and the dry season is quite long, the leaves fall dormant in summer, and are very sensitive to humidity and sweltering heat.

2) Light: Prefer a sunny environment, even in the summer high temperature season, there is no need for shade. Although it can grow in semi-light conditions, it does not grow as well as plants in full light.

The light hall needs to be shaded in summer, especially when it rains for a long time and the weather is fine, so as not to burn the stems.

3) Watering: Drought tolerant, avoid stagnant water. The watering of the growing period should grasp the principle of "thousands of wets alternately and dry", and the potting soil must be dried before watering to prevent the potting soil from being too wet or waterlogged, otherwise it is very easy to cause rotten roots, but it should not be too dry, otherwise it will also cause leaf fall.

During the dormant period of winter, the leaves fall off, and the water should be controlled to keep the potting soil relatively dry. Unlike other plants of the genus Chuido, Kodo goes dormant after the leaves have fallen in summer, and should be watered sparingly to avoid causing rot.

4) Fertilization: In the spring and autumn growing season, thin fertilizer should be applied once every 15 20 days to promote plant growth. Stop fertilizing in summer and winter when dormant.

5) Turning pot: like fertile and loose and well-drained sandy loam soil, the substrate can be prepared with humus, garden soil and coarse sand and other materials, and mixed with an appropriate amount of calcareous materials. When planting, some well-rotted cow dung should be put at the bottom of the pot as base fertilizer.

Potted plants are repotted once every 1 2 years, and should be done in spring and autumn when growth is slow.

6) Pest control: there is a root rot hazard, often caused by underground pests after biting, and underground pests should be controlled. In addition, there are insect pests such as whiteflies and spider mites.

Succulent trees. The height of the native ground can reach 8 meters, the height of the potted plant is 30 50 cm, the single stem is erect, thick and fleshy, the whole body is sharp, and the linear leaves are gathered on the top of the stem; The adult plant bears white flowers. Sandy loam potted soil, requiring good drainage; Fertilization is applied once every 4 weeks during the growing period; Watering when the potting soil is dry, resistant to drought and afraid of moisture; The suitable temperature for growth is 20 30, and the overwintering temperature is about 13.

Likes full sunshine and is not tolerant of shade.

African overlord tree.

Soil cultivation of the African overlord tree:1Soil selection and planting:

The potting soil can be fully stirred with cinder, vegetable garden soil, dry cow dung, superphosphate potassium, in the proportion of 6 or 8 parts of cinder, peat soil and cow dung 1 part each, and spread out after natural fermentation for about 30 days, and can be potted in the sun for 7 days. When the seedlings grow to 6 8 cm, the seedlings are planted on sunny days.

2.Watering and fertilization: When the seedlings first germinate, the plants are young, have poor resistance, and are sensitive to water, so the soil water holding capacity should be kept at about 70%. If it is too dry, the seedlings will lose water seriously and will easily dry up and die; If it is too wet, it is easy to cause root rot.

The seedlings do not have strict water requirements, and the potting soil alternates between dry and wet, which is conducive to the growth of the root system and the growth of the plant. It should not be too dry or too wet.

The fertilization of African overlord tree, in the seedling stage, apply compound fertilizer water or 1% organic fertilizer every 7 days, and the concentration should not be too high, otherwise the seedlings are easy to hurt the roots and die. During the growth period of adult plants, compound fertilizer water or 2% organic fertilizer solution should be applied every 10 to 15 days to accelerate plant growth.

3.Temperature control and light control: African overlord tree can grow in full light or half light, greenhouse cultivation should be placed in a sunny place, sex likes high temperature, the growth period is spring and summer, and the growth temperature is 20 25. Dormant at 0 5 and susceptible to frost damage below 0.

4.Control of diseases and insects: African overlord trees are prone to anthracnose and blight during the growth period, and they are controlled with 800 times Dixon or 500 times Tobuzin. If there is scale insect and red spider damage, it can be killed with 800 1000 times of gmite or hydroamidothion.
