How to maintain aster? Aster cultivation methods and precautions

Annual herbaceous plant. Prefers warmth, humidity and plenty of sunshine. Fear of high temperatures, humidity and poor ventilation.

The suitable temperature for growth is 15 25, and the temperature in winter is not less than 3; Stems and leaves below 0 are susceptible to frost damage. The temperature is more than 30, the flowering is reduced and the quality is poor. Fertile, well-drained sandy loam soil is selected for ground planting, and a mixture of fertile garden soil, humus soil and perlite is used for potting plants.

Transplant once 2 3 weeks after emergence, and plant in pots or ground when the seedlings have 5 or 6 leaves. The potting soil is too wet during the growth period, which is easy to cause leaf growth, lodging and induce disease. Fertilize once every ten years, and apply phosphorus and potassium fertilizer once before flowering.

It is a cross-pollinated plant, and the natural hybridization rate of double-petaled varieties is low, and it is easy to maintain variety traits. Varieties with low double petals have a high natural hybridization rate, and the seeds must be isolated. Prevent rust and red spider infestation.

Aster. Aster.

Aster maintenance method:

1.Soil requirements

Aster is not strict on soil requirements and is generally grown in a lotty, moist, well-drained sandy soil.

2.Lighting requirements

Aster is a long-day plant, and it generally needs to ensure 15 hours of light every day, which can promote the healthy growth of the plant and allow the aster to bloom early.

3.Watering management

The growth of aster needs sufficient water, it is necessary to keep the soil moist, and it is necessary to grasp a certain amount when watering, and do not water too much, which can easily lead to root rot.

4.Temperature requirements

Aster is a hardy plant and needs to be moved indoors for maintenance during the northern winters. The most suitable temperature for the growth of aster is 15-25, and the indoor temperature in winter should not be lower than 3, otherwise it will frostbite the roots.

When the aster is in full bloom, it is best to let it be exposed to about 8 hours of light every day, so that the aster can grow strongly. The most suitable temperature for growing aster is 15-25, it is not heat or cold tolerant. Cultivated aster should be watered according to factors such as season and air humidity, and thin fertilizer should be applied frequently during its vigorous growth period.

1. Sufficient light.

If you want to maintain the aster, you need to give it enough light, aster is a plant with a high demand for light, it is best to let it be exposed to about 8 hours of light every day when the aster is in full bloom, so that the aster can grow robustly, the flowers will bloom better, and the ornamental nature of the plant will be greatly reduced when the light is insufficient.

2. Suitable temperature.

It is also necessary to give the aster a suitable temperature environment, the aster likes warmth, the most suitable temperature for its growth is 15-25, the plant is not cold and not heat-resistant, so the high temperature in summer needs to take cooling measures, put the plant in a cool place to maintain, and sprinkle water around the leaves to cool it, it is best to move back to indoor maintenance in winter.

3. Water and fertilizer application.

Breeding aster needs to be watered according to factors such as season and air humidity, spring and autumn plants can be watered once every 2-3 days during the vigorous growth period, the water evaporates quickly in summer, it is best to water once a day, and the number of watering needs to be reduced in winter. Nitrogen fertilizer can be applied every half month during the vigorous growth period, and phosphorus and potassium fertilizer can also be applied before and after flowering.

1. Give water, aster likes a humid environment, but is afraid of too wet, is a shallow root plant, so in the growth period to keep the potting soil moist, which is conducive to the growth of plants, due to the relatively dry summer, can be appropriately increased the number of watering.

2. Light, Aster prefers a warm, sunny environment, and grows vigorously in a well-ventilated and sunny environment.

3. Aster is more sensitive to sunlight and likes sunlight.

4. Temperature, the suitable growth temperature of aster is 15-25, the cold resistance is relatively weak, and it is not resistant to extreme heat. In winter, the temperature should not be lower than 3, and if the temperature reaches below 0, the stems and leaves will be damaged by frost. In summer, if the temperature exceeds 30, it will cause the aster to bloom less or the flowering time will be delayed.

5. Soil, Aster likes fertile and moist soil with good drainage, generally loam and sandy loam soil, and appropriate fertilization is applied according to the growth of plants.

The cultivation methods and precautions of aster are as follows:1. Maintain sufficient light;

2. Maintain a suitable growth temperature of 15 25;

3. Watering properly and avoid stagnant water;

4. Water nitrogen, phosphorus and potassium organic compound fertilizer every 15 days to promote plant growth and development;

5. To prevent pests and diseases, if infected, pick leaves and spray pesticides in time, and pay attention to maintaining a good ventilation environment.

Aster (scientific name: Callistephus chinensis (L.).Nees) annual or biennial herbaceous plant of the Asteraceae family.

Height (15) 30-100 cm. The stems are erect, solitary, covered with white rough hairs. Leaves ovate or oblong, capitate.

The petals are light white, light red, blue-violet and other colors. The corolla of the amphiroditic flowers is yellow. achenes oblong-elliptic, inverted-lanceolate, slightly flattened, flowering and fruiting stage:

May-October.

It is produced in Jilin, Liaoning, Hebei, Shanxi, Shandong, Yunnan and Sichuan provinces in China. It grows in the barren land of hillsides, grasses on hillsides, watersides or sparse forests. 30-2700 meters above sea level.

It is often cited as an ornamental planter in botanical gardens, gardens, courtyards and other public places. There are a wide range of cultivated and wild types in Japan and Korea. Botanical gardens in the former Soviet Union and other European countries have introduced flowers for ornamentation.

Growth habits. Aster is a shallow-rooted plant, and it is necessary to pay attention to water supply during the dry season. It is a robust plant, does not choose the soil, but has fertilizer-loving, grows better in fertile sandy soil, likes sunlight, likes moisture, is not tolerant to waterlogging, and is susceptible to pests and diseases at high temperature and humidity.

The heat resistance and cold resistance are poor. High-type varieties have strong adaptability and can be planted anywhere, while medium-short varieties have poor adaptability and should be carefully managed.

Aster likes to grow in a more humid environment, sufficient water can make it grow more vigorous, in spring and autumn when watering every 2-3 days, according to the specific situation to control the amount of water, it is best to keep the soil moist, in summer it is best to about once a day. In winter, in order to avoid frostbite, once every 5-7 days is sufficient.

It prefers sufficient light, and it is best to let it receive light throughout the day every day, only in this way can the plant fully convert sunlight into energy and grow vigorously.

The warm environment is more suitable for its growth, and usually flower friends try to control the temperature at 15-25 when breeding. In the summer high temperature environment, it is necessary to transfer it to a cooler place for maintenance. In winter, pay attention to the cold, less than 3 is likely to get frostbite.

Aster is more like fertilizer, usually to apply fertilizer to it is best to rot farmhouse organic fertilizer, if it is just set seedlings can also be applied liquid fertilizer, in the growth period to apply nitrogen fertilizer can effectively promote its growth, every 10 days can be applied once.

Sufficient fertilizer can make it grow more vigorous and robust, but also pay attention to the amount of fertilizer, not too much. It likes light, but in the summer when the temperature is high, pay attention to transfer and ventilation, the plant will be dehydrated and die in hot and sunny weather.
