Qingdao's cold-resistant cultivation methods teach you Qingdao's cold-resistant cultivation methods.

1. The suitable temperature of winter flowers is between 15~32℃, which requires a certain temperature difference. The environmental humidity is above 60%, and most varieties can tolerate the low temperature of -8℃. Camellia cultivation soil should be acidic and require good air permeability. In order to promote the growth of root hairs, peat, sawdust, red soil, humus soil or a mixture of the above substrates can usually be used for culture.

2. Cold-resistant flowers are usually watered with neutral or acidic surface water. Watering should be both wet and dry. When it is dry, water it thoroughly, but be careful not to be too dry. Generally, water should be stopped at the end of spring shoots before germination to facilitate the transformation to reproductive growth, and water should not be stopped before flowering.

3. Resist winter flowers like fertilizer. When you are in the basin, you should pay attention to putting base fertilizer, mainly phosphorus and potassium fertilizer, in the basin soil. Fertilizers applied include decomposed bone meal, hair, chicken feathers, chaff ash, poultry manure and calcium superphosphate. Usually, it is not advisable to apply too much fertilizer. Generally, 2 ~ 3 times of thin fertilizer water should be applied in April ~ May after flowering, and a little thicker fertilizer should be applied in autumn165438+1October.

4. Cold-resistant flowers grow slowly and should not be excessively pruned. It generally affects the long branches of trees, as well as the branches and weak branches of pests and diseases. If there are too many buds on each branch, only 1 ~ 2 can be thinned to keep a certain distance, and the rest can be picked as soon as possible to avoid consuming nutrients.

5, feeding precautions, when the temperature is lower than 0 degrees, it will cause buds, buds and so on. Be frozen. If the temperature is below 0 degrees, please move to the room for maintenance. Pay attention to the accumulation of water in flowerpots in rainy days. If the water is not drained in time, the roots will be soaked in the water, which will lead to the flower's anoxia and decay.
