How to raise African Impatiens Culture methods and matters needing attention

Today, the editor is here to introduce African impatiens, which may be very strange to you. It is a plant growing in Africa. Bright colors and beautiful appearance. Many people want to keep some African impatiens at home. However, most people do not understand the living habits of flowers. I don't know how to raise it. Friends who like to grow flowers, don't worry, learn with the editor how to raise African impatiens!

How to raise African impatiens

1. Potted plants that pass the winter should be placed on a sunny windowsill or balcony, keep the room temperature above 12 ℃ and water once a week. If the room temperature is lower than 12 ℃, the leaves will turn yellow and even the basal leaves will fall. If the room temperature is kept above 16 ℃, the plant will bloom continuously as usual. The potted soil remains moist, but too wet will cause the plant to rot.

2. The weather began to get warmer, and the daily management of potted plants was the same as in January. The gradual rise of room temperature, if poor ventilation, prone to gray mold and stem rot, pay attention to prevention and control.

3. Potted plants enter the flowering stage, watering 2 ~ 3 times a week, and fertilizing once every 2 weeks. It is necessary to control the application rate of nitrogen fertilizer to prevent the excessive growth of stems and leaves and the decrease of flowering. Cutting propagation, cutting the full apical branch from the mother plant, growing 10cm~12cm, and inserting it into the sand bed. Under the condition of 20 ℃ ~ 25 ℃, it took root in about 3 weeks, and could be potted in 4 weeks.

4. The daily management of flowering period is the same as that of the previous month. Water insertion propagation, select the top branch, grow 10cm~1.2cm, insert half of the cuttings into clean water, change the water every 2 ~ 3 days, take root in about 10 days at 20 ℃ ~ 25 ℃ room temperature, and pot when the new shoots are high 3cm~5cm.

5. It is still in full bloom, and its daily management is the same as in April. If the seed is left, artificial pollination is carried out with a soft brush to improve the seed setting rate. Sowing and propagation, indoor pot sowing, small seeds, light-loving, no need to cover soil after sowing, the optimum temperature for germination is 16 ℃ ~ 18 ℃, and germinate about 2 weeks after sowing to prevent stunting disease at seedling stage. It takes 8 ~ 10 weeks from sowing to flowering and 10 ~ 14 weeks for hanging pot cultivation.

6. the high temperature season is very disadvantageous to the growth and flowering of the plant. Prevent strong light exposure, set up sunshade net, shade 40% to 50%, prevent sunburn. Too much watering can easily lead to rotten stems and rotten roots, so spray is often used to prevent leaf wilting. Do not use thick fertilizer when fertilizing to prevent the fertilizer liquid from contaminating the foliage. The heart was picked once when sowing seedlings were high 10cm.

7. with continuous high temperature, the daily management of potted plants is the same as that of last month. After 1 ~ 2 times of coring, the sowing seedlings gradually formed a full plant type. If the plant type has not yet been formed, when there are buds, it should be removed in time.

8. when the weather turns cool, clean up the withered leaves and flowers, water them once every 2-3 days, and apply fertilizer once every 2 weeks. Potted plants begin to blossom. Cutting propagation, cutting off robust tip branches, long 6cm~8cm, with 2 ~ 3 nodes, inserted into the mixed soil of peat and vermiculite, spraying water to keep moist, rooting for 2 ~ 3 weeks. Pay attention to ventilation to prevent the harm of leaf spot and red spider.

9. Keep potted plants safe from cold and survive the winter. Potted flowers are placed on a sunny windowsill or balcony, keep 10 ℃ ~ 15 ℃ at room temperature, water once a week, and stop fertilizing.

10. Continue to protect pot plants from cold and survive the winter. Potted flowers are placed on a sunny windowsill or balcony at room temperature for more than 10 ℃. In case of rain and snow, the watering interval is extended to prevent low temperature, humidity and stem rot.

Culture methods and matters needing attention of African impatiens

I. Culture methods of African impatiens

1. Temperature and light

The suitable temperature for the growth of African impatiens is about 15 ℃-25 ℃, and the indoor overwintering temperature should not be lower than 12 ℃. Should give sufficient light, but avoid scorching sun exposure, summer requires cool, and appropriate shade, ventilation.

2. Moisture

African impatiens like to be wet, often keep the basin soil moist, but also pay attention to avoid stagnant water, otherwise it is easy to cause plant waterlogging and death. Maintain a suitable air humidity, which is generally about 70% and 90%. In the case of dry weather in summer and autumn, you should often spray water to the leaves.

3. Soil

African impatiens is suitable to be cultivated in sandy loam with fertile and loose and good drainage.

II. Matters needing attention in African Impatiens Culture

Do a good job in the prevention and control of diseases and insect pests to ensure the healthy growth of plants. The common diseases are leaf spot and stem rot, which can be controlled by spraying 1000 times of carbendazim wettable powder. Insect pests are mainly caused by aphids, and 3000 times of insecticidal essential oil should be sprayed in time.

Pest control of African impatiens

1. Leaf spot and stem rot are often harmed, which can be controlled by spraying 1000 times of carbendazim wettable powder. The main aphid damage caused by insect pests should be sprayed with 3000 times of 10% deworming essential oil.

2. African impatiens powdery mildew, the symptom of which mainly occurs on leaves and shoots. It usually begins in June, and the leaves are covered with white powder layer after July. Subsequently, small yellow dots were formed in the powder layer, and the color gradually darkened, and finally showed dark brown. Control methods: planting is not too dense, proper ventilation, strengthen fertilizer and water management, enhance plant disease resistance. Remove diseased leaves and diseased plants and destroy them centrally so as to reduce the source of infection. During the onset of the disease, 10% verapamil wettable powder 1000-1200 times liquid or 70% methyl topiramate wettable powder 1000 times solution was used for prevention and treatment. Avoid spraying at a high temperature above 32 ℃ to avoid drug damage.

3. African impatiens brown spot, African impatiens brown spot, also known as impatiens leaf spot. Symptomatic diseases mainly occur in leaves. The foliar spot is a light yellowish brown spot at first, then expands into a circle or oval, and then the center becomes light brown, the edge is brown, with inconspicuous rims. On the seriously diseased leaves, there are a series of disease spots, which causes the leaves to become withered and yellow until the plant dies. Control method: African impatiens likes fertile sandy loam and is not resistant to waterlogging. Therefore, it is appropriate to plant sandy loam to facilitate drainage; potted African impatiens should be poured out in time after rain. Diseased leaves and plants should be destroyed at the end of autumn to reduce the source of infection in the coming year. The initial stage of the disease with 25% carbendazim wettable powder 300 times 600 times liquid, or 50% methyl topiramate 100 times solution, or 75% chlorothalonil 1000 times solution for prevention and treatment.

4. African impatiens blight, the symptom pathogen mainly infects the rhizome, the pathogenic part blackens or constricts, and white mildew grows on it when it is moist. After the plant is infected with the disease, the leaves wilt and wither within a few days, resulting in the death of the whole plant. It overwinters mainly in the form of mycelium or sclerotia in the soil or in the sick and disabled body, and the mycelium camp in the soil is saprophytic and does not dormant. In the field, it is mainly transmitted by contact, that is, when the roots, stems and leaves of the plant come into contact with the diseased soil, it will be infected by the hyphae in the soil. Under the condition of water film, the healthy leaves in contact with the diseased part will be infected. In addition, seeds, farm tools and bacteria-carrying compost can spread the disease.

Cutting methods of African Impatiens

1. Cutting time of African impatiens

African impatiens have the function of self-sowing, which spreads and propagates by itself after the seeds are mature. However, when raising African impatiens, cuttings can also be carried out, especially the double varieties. The best time for cuttage propagation of African impatiens is in spring and autumn.

2. Cuttage selection of African impatiens.

In the cuttage propagation of African impatiens, to choose a suitable cuttage, it is generally better to use the terminal bud for cutting, because the growth of the terminal bud is relatively fast, and the speed of rooting is also very fast. When cutting cuttings, the cuttings are usually cut off with terminal buds, and there are 5-node branches of 3murmuri for cutting, the length of which is about 5--10cm. Note that the flowers and buds should be removed, and the leaves in the lower half of the leaves should be removed.

3. Cutting and planting methods of African impatiens.

First of all, prepare the flowerpot in 7.5cm, fill it with perlite, be careful not to fill it, and then insert the cuttings into the soil. A pot can be cutted with 5 branches of 3muri. After cutting, the pot mouth can be covered with cling film, which is beneficial to the rooting of cuttings. In general, after African impatiens cuttings, 2-plum can take root in 3 weeks, and transplanting can be carried out at this time. When transplanting and planting, the flowerpot is filled with soil, and then the plant is filled with soil and compacted. Note that after planting, it is possible to pick the heart and shape a good plant type.

Generally speaking, African impatiens have strong vitality and are easy to feed. However, we must know its living habits in advance. In this growth process, it is inevitable that some pests will infect them. Friends who raise African impatiens, do you understand?
