How should the ten famous flower species be managed through the winter?
How are the ten famous flower species managed through the winter.
The following is an introduction to the wintering management methods for the ten famous flower species:
Tree peony: Potted tree peonies should be kept buried long-term in a sunny flower bed, and only dug up and moved indoors for viewing when the buds are about to open; otherwise, without cold exposure, they do not bloom easily. Before Frost's Descent, cut off the leaves but leave the leaf stalks to protect the axillary buds. Then gather the branches with straw rope and wrap them with three layers of newspaper, and they can get through the winter.
Chinese rose: Potted Chinese roses are brought indoors in late October. Cut off diseased and weak branches, choose and keep 8 to 5 strong branches, cut them back to 10 to 15 cm, and place them in a dark indoor spot, controlling fertilizer and water. As long as it does not freeze, they can get through the winter. To enjoy flowers in winter, keep them at 0°C: after 30-40 days, move them to 12°C to 14°C for care. Buds require 17°C to 18°C. Increase light, appropriately apply fertilizer and water, and control pests and diseases, and they will bloom.
Plum blossom: After leaf fall in autumn, move it indoors to a cool place, give it appropriate light, keep the potting soil moist, and as long as it does not freeze indoors, it can overwinter safely. About 20 days before Spring Festival, move it to a sunny, warm place, maintain 5-10°C, apply fertilizer and water appropriately, and it can bloom during Spring Festival.
Chrysanthemum: Chrysanthemums must be protected so the perennial roots neither freeze nor sprout, remaining in a dormant state. If tiller buds have already formed at the turn of autumn and winter, they can be cuttings and placed at 4-5°C in semi-shade to overwinter. After flowering, cut the stems and leave stubble 10-15 cm high in a sunny place, cover appropriately, and before deep winter move them indoors to a cool place, keeping them below 5°C without freezing, with soil neither wet nor dry, so they can rest.
Azalea: Bring indoors in mid-to-late October (after early frost appears); it can overwinter safely at no lower than 5°C. To enjoy flowers in winter, give a room temperature of 12°C, water and fertilize appropriately, keep the potting soil alternating between moist and dry, water with cool boiled water or improved tap water or alum fertilizer water, and avoid direct midday sunlight.
Orchid care: Orchids have four don'ts: "Do not take them out in spring, do not expose them to sun in summer, do not let them dry out in autumn, do not keep them wet in winter." In late autumn and winter, give stronger light to make growth robust. Bring indoors in early October, appropriately reduce watering, and keep the potting soil slightly drier than in summer and autumn; but air humidity should be relatively high; room temperature no lower than 5°C is enough.
Camellia: Bring indoors in early October (before Cold Dew), place where it can receive sunlight while avoiding direct midday sun, with room temperature no lower than 0°C. If the potting soil is too wet, roots will rot. Water with cool boiled water plus 0.05% ferrous sulfate. Also often spray and wash the leaf surfaces with lukewarm water close to room temperature to keep them fresh and deep green. In a 10°C-18°C environment, it can bloom in one month. If the temperature is too high, it blooms early and fades early too.
1. Temperature (each flower has its own low-temperature tolerance limit; you can look it up):
1. For flowers tolerant of low and cold temperatures (5-12°C, below 5°C), such as pomegranate, Chinese rose, wintersweet, osmanthus, palm, Chaenomeles speciosa and crape myrtle, they can be placed outdoors in a sunny courtyard or balcony.
2. For flowers that need to be kept at medium temperature (12-20°C), such as Michelia alba, camellia, azalea, banana shrub, clivia, fuchsia and wax begonia, they must be moved indoors before the temperature drops to 10°C.
3. For flowers that can grow normally only at high temperature (18-30°C), such as Aglaia odorata, hibiscus, jasmine, croton, narcissus, epiphyllum, orchid cactus, cactus, globe cactus and aloe, they must be moved indoors before the temperature drops to 12°C. Before the temperature drops to 5°C, put the flower pots in plastic bags, tie the plastic bags tightly, and leave a few small holes in the bags for ventilation. Around midday on clear, windless days, move them outdoors to sun for a few hours, then move them back indoors to keep warm.
How to grow flowers in winter (wintering management)
2. Pruning: Before potted flowers overwinter, they should be pruned and shaped in good time to reduce nutrient consumption and reduce the indoor space they occupy during winter.
3. Fertilizing: Apply fertilizer once before overwintering and water thoroughly. During overwintering, flowers generally should stop being fertilized.
4. Watering: Generally keep the potting soil dry and water less. For watering in December, the 3 to 4 hours around midday are best, and the water temperature should be kept basically consistent with the air temperature and soil temperature, to avoid adverse reactions in potted flowers caused by water that is too cold.
5. Ventilation: Pay attention to ventilating regularly, preferably on sunny days when there is sun, or at midday when the temperature is higher. When ventilating and exchanging air, you must also be careful not to let cold wind blow directly on the plants, so as to avoid adverse reactions.
6. Early spring: In early spring next year, generally from the Spring Equinox to Qingming, overwintered flowers can gradually be moved outdoors and given fertilizer and water, such as bio-organic fertilizer, yellow-leaf cure, trace-element water-soluble fertilizer, etc., so the flowers can grow normally in spring.
7. Pest and disease control: For flowering trees and shrubs whose leaves are prone to pests and diseases, such as begonia types, roses and camellias, collect the dead branches and fallen leaves under the plants and burn them, which can reduce disease occurrence next year. At the same time, spray carbendazim for sterilization and disinfection. For ** disease, rust disease, and primrose gray mold, use triadimefon or thiophanate-methyl respectively in good time. For flower species on which aphids often appear on potted plants when ventilation is poor, such as Michelia alba and Aglaia odorata, imidacloprid can be used for control. For scale insects, of course, the highly targeted Jie Bi Zhi must be used for control.
