This is also the time when most flowers enter the second growth period.
At this time, water and fertilizer management is extremely important for flowers.
1. water.
For most flowers, water should be poured every 1-2 days according to the dry and wet conditions of the basin soil, and water should be poured 1 time; For grass flowers that bloom in autumn and winter or in early spring and sow in autumn, they can be watered normally according to the actual needs of each flower, and other flowers should be watered gradually to avoid excessive water and fertilizer, which will cause excessive growth and affect flower bud differentiation and safe wintering; For foliage plants that like humidity, water should be sprayed 1-2 times in addition to watering every day; For some acid-loving flower seeds, a proper amount of ferrous sulfate can be added to the water, and the concentration should not exceed 0.65438 0%.
2. Fertilize.
Because this is the period when most flowers grow vigorously, besides ensuring water supply, fertilization is also very important.
According to the habits and needs of different flower species, different types and concentrations should be topdressing.
For autumn chrysanthemum, osmanthus, camellia, azalea and so on. Flowers bloom once a year, and liquid fertilizer mainly containing phosphate fertilizer should be applied 2-3 times in time, otherwise, not only the flowers are small, but also the buds will drop; For fruit-watching plants that bloom many times a year, such as rose, Milan, jasmine, hibiscus, begonia, kumquat, pomegranate, etc., in addition to ensuring the supply of nitrogen fertilizer, an appropriate amount of phosphorus and potassium fertilizer, such as potassium dihydrogen phosphate and calcium superphosphate, should be applied topdressing; Low concentration nitrogen-containing liquid fertilizer can be applied to foliage plants such as Phyllostachys pubescens and Brazilian wood to promote lush and green leaves; For most flowers, after the cold dew in the northern region, the temperature becomes lower, and fertilization is generally not needed.
3. Plastic decoration.
When the temperature is around 20℃ in autumn, many flowers will sprout. Except some shoots, the rest should be cut off in time to reduce nutrient consumption.
The remaining shoots should also be picked in time to prevent white growth; For chrysanthemum, rose, hibiscus and other flowers that bud in autumn, in addition to keeping the top main bud, we should also remove the side buds in time; For varieties with long flowering period, such as rose, hibiscus, jasmine, geranium and so on. The flowering residual flowers and stems should be removed in time, and the flowering branches should be trimmed to promote the growth of the lower tips so as to continue flowering.
Before and after the cold dew festival in the northern region, most flowers should be moved indoors one after another according to their cold resistance to avoid freezing injury.
The time to enter the room varies according to the type and area of flowers.
For most flowers, if there is no frost as soon as the weather turns cold, don't rush to move indoors, because premature entry will affect the accumulation of nutrients, which is not conducive to next year's fertility.
Therefore, under the premise of not suffering from freezing damage, the time to enter the room should be a little late.
