Whether plants need fertilization in winter is determined by different plants, not that they don't need fertilization as it is said by mistake. Like some flowering plants in winter, because the opening of flowers will consume nutrients and also need nutrients to grow, it is still necessary to add nutrients regularly in winter. Some plants with green leaf color in winter can also apply some compound fertilizer to ensure the ornamental value of leaves. But by the winter has entered the dormancy period or semi dormancy period of plants, their growth activities are basically stagnant, there is no need to apply fertilizer.
When winter comes, ornamental leaves such as pothos and Chlorophytum can be lengthened, and fertilizer can be applied once a month or a half a month, so that growth can be satisfied. But in winter flowering plants, such as camellia, plum, etc., still need to be applied regularly to ensure that the flowers open. And Begonia flowers to the winter has entered the dormancy period, it is no longer needed, can wait until a year's spring to impose nutrients
