Tips for growing flowers in winter

1. Temperature

1. For flowers that can withstand low temperatures and cold temperatures (5 to 12 °C, below 5 °C ) , such as pomegranate, rose, wintersweet, osmanthus, palm, crabapple and crape myrtle, they can be placed in sunny places in outdoor courtyards or balconies.

2. Flowers that need to maintain a moderate temperature (12 to 20 °C ) , such as white jasmine, camellia, azalea, Michelia, Clivia, fuchsia and begonia, must be moved indoors before the temperature drops to 10 °C.

3. For flowers that can only grow normally under high temperatures (18 to 30 °C ) , such as Milan, hibiscus, jasmine, croton, narcissus, epiphyllum, Euphorbia, cactus, prickly pear 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 and tie the plastic bags tightly, leaving a small number of air holes on the bags for ventilation. Around noon when the weather is clear and windless, move it outdoors to bask in the sun for a few hours and then move it back indoors to keep warm.

2. Pruning

Before potted flowers hibernate, they should be pruned and trimmed in time to reduce nutrient consumption and reduce the space occupied indoors during the winter.

3. Fertilization

Apply fertilizer once before wintering and water sufficiently. During the winter, it is generally necessary to stop fertilizing flowers.

4. Watering

Generally, keep the soil in the pot dry and water less often. The best time for watering in December is 3 to 4 hours around noon, and keep the water temperature basically consistent with the air temperature and soil temperature to avoid adverse reactions in potted flowers due to low water temperature.

5. Ventilation

Be sure to ventilate the room regularly, preferably on sunny days or at noon when the temperature is higher. When ventilating, you must also be careful not to let cold air blow directly on the plants to avoid adverse reactions.

6. Spring

In the early spring of next year, generally between the Spring Equinox and Qingming Festival, the overwintering flowers can be moved outdoors one after another and fertilized with fertilizers and water, such as biological organic fertilizers, yellow leaf fertilizers, trace element water-soluble fertilizers, etc., to allow the flowers to grow normally in the spring.

7. Pest and disease control

For flowers and trees such as crabapples, roses, and camellias whose leaves are prone to diseases and insect pests, collecting the dead branches and leaves under the plants and burning them can reduce the occurrence of diseases next year.

In winter, some shallow-pot landscape bonsai and tree stump bonsai must be carefully managed.

1. Prevent the pot soil from freezing and damaging the plant roots;

2. Prevent freezing from causing artificially cemented rocks to disintegrate;

3. Prevent plants planted on the rockery from freezing or drying out.

It can be placed in a place where it does not freeze and watered regularly so that it can safely overwinter.
