How to manage overwintering for home-grown flowers? Seven aspects to pay attention to

Flowers & Gardening Jan 1, 1970 0 views

Winter is here, and how to care for flowers in winter has become a tricky matter, especially in places without heating. First of all, flower lovers need to be clear about the conditions they can provide for their plants. Some flowers and plants will freeze to death no matter how they are cared for when the temperature is too low, so the key to growing flowers in winter lies in providing temperature protection. If you are unable to provide it, you should be mentally prepared, because for now there are no techniques that can let tropical plants withstand the cold. Below are several aspects of overwintering flowers and plants.

PS: There are many ways to increase temperature, and flower lovers can get creative themselves, such as small greenhouses, wind protection, etc. Choose the one that suits you best.

I. Temperature

1. For flowers that can tolerate low temperatures and cold temperatures (5°C-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 courtyard or on a balcony in a sunny spot.

2. For flowers that need to be kept at medium temperature (12°C-20°C), such as white orchid, camellia, rhododendron, banana shrub, clivia, fuchsia and wax begonia, they must be moved indoors before the temperature drops to 10°C.

3. For flowers that can only grow normally at high temperatures (18°C-30°C), such as: Aglaia odorata, hibiscus, jasmine, croton, narcissus, epiphyllum, orchid cactus, cactus, cactus ball types and aloe, they must be moved indoors before the temperature drops to 12°C. Before the temperature drops to 5°C, cover the flower pots with plastic bags, tie the plastic bags tightly, and leave a small number of air holes in the bags for ventilation. Around noon on clear and windless days, move them outdoors to bask in the sun for a few hours, then move them back indoors to keep warm.

II. Pruning

Before potted flowers overwinter, they should be pruned and trimmed in good time to reduce nutrient consumption and reduce the indoor space they occupy during overwintering.

III. Fertilizing

Apply fertilizer once before overwintering and water thoroughly. During overwintering, fertilizing should generally stop for flowers.

IV. Watering

Generally keep the potting soil dry and water less. In December, the best watering time is the 3-4 hours around noon, 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.

V. Ventilation

Pay attention to ventilating regularly, preferably on sunny days when there is sun, or at noon 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.

VI. Early spring

In early spring next year, generally during the period 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 treatment, trace-element water-soluble fertilizer, etc., so that the flowers can grow normally in spring.

VII. Pest and disease control

For flowering trees whose leaves are prone to pests and diseases, such as crabapple types, roses and camellias, collect the dead branches and fallen leaves under the plants and burn them, which can reduce the occurrence of diseases next year. At the same time, spray carbendazim for sterilization and disinfection. For ** disease, rust disease, and gray mold of primroses, timely use triadimefon or thiophanate-methyl respectively for control. For flower and tree species that often develop aphids on potted plants when ventilation is poor, such as white orchid and Aglaia odorata, imidacloprid can be used for control. For scale insects, of course, the highly targeted scale insect treatment must be used.

In winter, for some shallow-pot landscape bonsai and stump bonsai, you must manage them carefully.

1. Prevent the potting soil from freezing and damaging the plant roots.

2. Prevent freezing from causing the artificially bonded rocks to break apart.

3. Prevent the plants planted on the rockery from freezing to death or drying to death. They can be placed in a place that does not freeze, and watered and misted regularly so that they can overwinter safely.
