Key points of overwintering maintenance of family flowers in winter

Winter temperature is not suitable for the growth of most flowers, in order to make potted flowers safe winter, in early winter need to move into the room, after entering the maintenance measures, placement position should take into account the characteristics of various flowers.

Temperature: Adjust appropriately according to different flowers

In the northern region, the winter climate is cold and the temperature is low. Generally, southern flowers need to be moved indoors for wintering, and adjust the appropriate temperature according to the requirements of different flowers. High-temperature flowers, such as Milan, poinsettia, African balsam, begonia and cactus succulent flowers, should try to place the flowerpot in sunny, high temperature (between 20℃ and 25℃) indoor windowsill, the minimum temperature shall not be lower than 10℃. Mid-temperature flowers, such as jasmine, geranium, rose, evergreen, winter suitable temperature is 18℃-22℃, the minimum temperature shall not be lower than 6℃. Low-temperature flowers, such as kumquat, osmanthus, orchids, winter temperature should be maintained between 12℃-15℃, the minimum temperature should not be lower than 2℃. Aquatic flowers, such as lotus, water lily, water hyacinth, Naphtalum, etc., should be drained in time before frost, the flowerpot moved to the cellar or corridor hall, the temperature should be kept at 5℃, and the pot soil should be sprayed properly when it is dry.

In addition, winter and spring flowering flowers and sexual love light, warm flowers, such as crab claw orchid, cyclamen, camellia, poinsettia, Milan, jasmine, etc., should be placed on the windowsill or near the windowsill sunny place. Evergreen flowers and trees that like sunshine but can withstand low temperatures or flowers in a dormant state: such as osmanthus, citrus, can be placed in a cold place with scattered light. Generally, flowers that are not strict with light requirements, such as potted water lilies and roses, can be placed in cold places without light.

Fertilization: Minimize or stop

Most flowers enter dormancy in winter, so try to reduce or stop fertilization. Indoor flowers that do not dormancy in winter, such as evergreen flowers such as tiger tail orchid, fish tail sunflower, palm bamboo and green radish, basically have no requirement for fertilizer when the room temperature is about 5℃, so they do not need topdressing. If the temperature is low, fertilization is easy to cause root rot. The main reason is that the root growth of winter plants is in a slow state, and the fertilizer applied cannot be absorbed by the root system, but it will hinder the normal absorption of the root, and when it is serious, it will rot the root.
