The maintenance and management of potted flowers in autumn should be three in time.

With the change of autumn time and seasons, the ambient temperature is gradually changing. Autumn is a crucial growing season for potted flowers. Of course, how to protect potted flowers in autumn is also something that flower growers often study and hate. Autumn climate changes from hot summer to cool gradually, when everything begins to wither, and potted flowers should be maintained more carefully. Therefore, at this time, potted flower management should pay attention to the following management work.

First, three timely maintenance of flowers in autumn

1. Lighting: light in time for some light-loving woody flowers that bloom in summer, such as jasmine, Fusang, Jiuli incense, etc., should still be placed in a sunny place. Flowering rhododendron, magnolia, cyclamen, poinsettia, crab claw orchid and other potted flowers before and after the Spring Festival should also be placed in sunny places.

2. Pruning: pruning timely except for flowers that bloom in early spring, most flowers, such as jasmine, crape myrtle and pomegranate, can be pruned and shaped in autumn, which can reduce the consumption of nutrients in winter and increase the number of potted flowers the following year.

3. Breeding: when the temperature is low in autumn, some biennial flowers, such as pansy, carnation, melon and leaf chrysanthemum, hollyhock, etc., are good time to sow seeds. Pay attention to spraying water after sowing to keep the soil moist. There are some woody flowers suitable for cutting in autumn, such as rose, geranium, jasmine, etc., with a higher survival rate in autumn. Perennial root flowers that need ramets for dense growth, such as peony and peony, should be propagated in time. Flowers that bloom before and after the Spring Festival, such as hyacinth, tulips, Zhu Dinghong, etc., should be put on the pot as soon as possible. Cao Qidong

Second, how to manage potted flowers in autumn

1. Proper amount of water and fertilizer: the management of water and fertilizer after autumn should be treated differently according to the habits of different flowers. For autumn chrysanthemum, sweet-scented osmanthus, camellia, rhododendron, wax plum, etc., which bloom once a year, liquid fertilizer dominated by phosphate fertilizer should be applied 2 or 3 times in time, otherwise not only the flowers will be small, but also the buds will fall. For the rose, Milan and jasmine which bloom many times a year, we should continue to provide more sufficient water and fertilizer to promote its continuous flowering. For most flowers, after Cold Dew Festival in the north, there is generally no more fertilization to facilitate overwintering. With the decrease of air temperature, except for the flowers flowering in autumn, winter or early spring and those sown in autumn, which can continue to be watered normally according to the actual needs of each kind of flowers, the watering times and amount of water for other flowers should be gradually reduced to avoid excessive water and fertilizer and cause excessive growth. affect flower bud differentiation and suffer frost injury.

2. Pruning and shaping: when the temperature is about 20 ℃ after autumn, most flowers are easy to sprout more twigs. Except for keeping some of them as needed, the rest should be cut off in time to reduce nutrient consumption. The retained twigs should also be plucked in time. For chrysanthemum, dahlia, rose, jasmine and so on, when the buds grow to a certain size after budding in autumn, the lateral buds are removed except for a large bud with good growth at the top.

3. Timely seed harvesting: the seeds of many flowers mature one after another before and after mid-autumn and need to be harvested in time. A bunch of red, pineapple, morning glory and other seeds are dried after harvest and stored in a cloth bag in a low-temperature ventilated place. For some seeds with thick seed coat, such as peony, peony, magnolia, Michelia, etc., the seeds should be buried in wet sand and stored in stratified sand after harvest.

4. Sowing at the right time: biennial or perennial grass flowers cultivated in one or two years, such as goldfish grass, carnation, daisy, greenhouse flowers such as melon and leaf chrysanthemum, cyclamen, big rock tree and other greenhouse flowers, as well as African chrysanthemum, swallows, primroses, begonias and other flowers that are easy to lose their ability to germinate after harvest are suitable for autumn sowing.

5. Enter the house at the right time: after Cold Dew's festival in the north, most flowers should be moved indoors one after another to survive the winter according to the strength of cold resistance, so as to avoid cold damage. The specific time to enter the room varies from time to time. For most flowers, don't rush into the house as soon as the weather has just changed. Because entering the house too early affects the accumulation of nutrients, which is not conducive to the growth and development of the coming year. Therefore, under the premise of not suffering from cold injury, it is better to enter the room a little later.
