Third, winter: when the winter temperature is low, it is not suitable for the growth of most flowers. Indoor flowers that do not sleep in winter, such as evergreen flowers, tigertail orchid, fishtail, brown bamboo, and green radish. There is basically no requirement for fertilizer at room temperature around 5 Â°C, so no top dressing is required. If the temperature is low, fertilization is prone to root rot. The main reason is that the root growth is in a slow state, and the applied fertilizer cannot be absorbed by the root system, but it will hinder the normal absorption of the root, and in the case of severe, it will rot. However, some flowers can grow well when the temperature is low in winter. For example, flower cabbage, cold water, sea bream, etc., nitrogen, phosphorus and potassium can be used with nitrogen fertilizer as the main fertilizer, but the dosage should be properly controlled.
