The flowers suitable for planting in September have entered the golden autumn in a blink of an eye, and the temperature is not as hot as before. Friends who like flowers and plants can also start planting. What are the flowers suitable for planting in September? The following is the information of flowers suitable for planting in September for your reference.
Flowers suitable for planting in September 1 First of all, planting daisies in early autumn can bloom in late winter.
Daisies grow very fast. If planted in September ~ 65438+1October of that year, it will bloom in February ~ March of the following year. Before sowing, the seeds can be soaked in water overnight, and then the seeds can be evenly spread on the culture soil and covered with a thin layer of soil about 3 mm thick.
After sowing, spray water to keep moisture, and keep the temperature at about 18 ~ 20℃. Do not put it on the balcony with strong sunlight, and move it to an indoor environment with scattered sunlight and ventilation for maintenance. Generally, it will germinate in 5 ~ 8 days, and then move to the balcony for maintenance. Daisies grow rapidly after emergence, and usually bloom in late winter and early spring.
Second, Eustoma grandiflorum, sowing in autumn, flowering in spring
The seeds of Euonymus grandiflorus are sown in September ~ 65438+1October, and generally bloom in April ~ May of the following year. The seed of Eustoma grandiflorum is very small. Don't cover the soil after sowing the seeds in the pot soil, just press it gently.
The seeds of Eustoma grandiflorum are like light. After sowing, it can be placed directly on the balcony to receive direct sunlight to maintain the humidity of the soil. If the temperature is around 22 ~ 24℃, they can germinate in 10 ~ 14 days.
Third, the sky is full of stars, and the balcony is starry in May.
The seeds of gypsophila paniculata are sown in September and usually bloom from May to July of the following year. Because the sky is afraid of heat, it is very laborious to spend the summer after spring sowing, so it is more suitable for autumn sowing. You don't need to buy flower soil for sowing, just dig some garden soil. Before sowing, water the soil thoroughly, and then spread the seeds of gypsophila paniculata evenly on it and cover it with a thin layer of soil.
First put it in a cool and ventilated place for seedling emergence, and keep the temperature at about 20℃. Generally, the seeds of gypsophila paniculata will germinate in about 10 days. After 20 ~ 25 days of growth, the seedlings of gypsophila paniculata need proper topping to promote branching, so that the flowers will bloom more brilliantly in the coming year.
Fourth, Fulu scones were opened twice in late spring and late summer respectively.
Fluconazole can bloom twice a year, in late spring (May) and late summer (August). Before sowing, the fluconazole seeds were soaked in warm water overnight, and then evenly spread on the surface of the culture soil, covered with a thin layer of soil about 3 mm.
The optimum temperature for seed germination is about 20 ~ 22℃. If the soil is kept moist, seeds can germinate in about 7 ~10 days. It can be opened once in May of the following year, the flowering period lasts for two months, and it will be opened for the second time in August.
Bellflower blooms in May after winter.
Hyacinthus orientalis doesn't blossom for at least one winter after sowing, which means it is difficult to blossom in the same year after spring sowing, so autumn sowing is the most suitable. Sow bellflower seeds evenly on the culture soil, and then cover with a thin layer of soil, not too thick, otherwise it will increase the difficulty of breaking the soil.
After sowing, the temperature is controlled at about 20 ~ 22℃ to keep the soil slightly wet. Don't put it on the balcony in direct sunlight after sowing, and keep it cool and ventilated properly. Generally, it will germinate in about two weeks, and then move to the sun for maintenance.
Suitable for planting flowers in September 2. Matters needing attention in planting flowers in autumn
1, strengthen fertilizer and water management
Apply phosphorus and potassium fertilizer to the dormant flowers in winter. Nitrogen fertilizer can still be applied to flowers that are not dormant in winter, especially to foliage plants. However, attention should be paid to the coordination with phosphorus and potassium fertilizer when applying. Reasonable application of phosphorus and potassium fertilizer can improve the cold resistance of flowers. Plants that bloom in winter, such as Guayeju, calceolaria, Cyclamen persicum, Poinsettia, Chimonanthus praecox, etc., are in the vegetative growth period in early autumn, and should be mainly applied with nitrogen fertilizer, while most of them are in the bud stage in late autumn, and should be mainly applied with phosphorus and potassium fertilizer, supplemented with nitrogen fertilizer. Excessive nitrogen fertilizer is not conducive to winter flowering. Flowers and seedlings planted in the open field are generally not watered when the soil is dry, but watered thoroughly. Potted flowers should be watered frequently and thoroughly, not halfway, which will form wet top and dry bottom and affect root growth; We should also prevent excessive watering and root rot. After autumn, we should control the supply of water to make the new shoots mature, and avoid the emergence of new shoots in late autumn and winter, which is not conducive to overwintering. But in early autumn or Mid-Autumn Festival, because of the high temperature, new buds appear in the flower seedlings. During this period, sufficient moisture should be provided to ensure that new shoots can grow and mature in time. The watering time in autumn should be in the morning and afternoon. Its purpose is to make the water temperature close to the soil temperature, which is beneficial to absorption and avoids root damage.
2. Pay attention to the adjustment of flowering period
Many flowers are arranged to bloom during New Year's Day and Spring Festival, which should be promoted or suppressed. If the gypsophila paniculata is a flower with long sunshine time, and it is required to bloom in winter, it must be replenished from the beginning of September. Generally 1 month, increase the light for 4 hours from 10: 00 to 2: 00 in the morning. Chrysanthemum is a flower with short sunshine, so it must be supplemented with light to delay flowering. The light supplement also started in mid-September and stopped 50 days before the expected flowering. For some warm flowers, such as Anthurium andraeanum and Phalaenopsis. When the daily average temperature is lower than 65438 05℃, attention should be paid to heating. Lily should be cultivated in autumn and winter. In addition to low temperature heating, it should also be illuminated to prevent hidden buds.
3. Strengthen pest control.
Insect pests in autumn mainly include carnation, gypsophila paniculata against Pieris rapae, gerbera against spider mite, chrysanthemum against Pieris rapae and aphid, and lily against aphid. Main diseases: chrysanthemum stripe virus, rose black spot, powdery mildew, carnation leaf spot, gerbera leaf spot, etc. Focus on disease prevention, pay attention to ventilation, reduce the air humidity in greenhouse, apply more phosphorus and potassium fertilizer, improve the disease resistance of plants and do a good job in spraying protection.
4, intertillage weeding
Intertillage can loosen topsoil, reduce water evaporation, increase soil moisture, promote air circulation and nutrient decomposition in soil, and create favorable conditions for flower root growth and nutrient absorption. Weeding can prevent weeds and flowers from competing for soil nutrients, water and sunlight. Intertillage can weed at the same time, but weeding can't replace intertillage. The depth of intertillage is generally 3 to 5 cm. At the same time, intertillage weeding can also help prevent pests and diseases and reduce the probability of pests and diseases in the coming year.
5, plastic pruning
Pruning in autumn should focus on "light" to avoid "heavy" leading to tree weakness and death. Pruning methods mainly include coring and pruning. Give priority to with the natural shape of plants, according to the need for plastic surgery. Among them, the trees are mainly pruned, and the trunk is highlighted to ensure that the trunk reaches a certain height before branching; Shrubs mainly maintain their original shape or promote their ideal shape and expand their crown width by coring. The quality of flowers can be improved by shaping and pruning.
