在冬季，休眠状态的盆栽花卉不需要追肥。这些植物包括石榴、吊钟海棠、扶桑、仙人掌、球根海棠、八仙花、垂丝海棠、寿星桃等。此类植物在冬季或翌春必须更换土壤并施以足够的基肥，以促进来年生长和开花。

对于观叶盆栽，在冬季可以适量施用复合肥和硫酸亚铁。这类植物有龟背竹、春羽、一些变叶木品种以及绣球松等。氮和铁元素可保持叶片光泽鲜绿，而钾素则增强抗寒能力。施肥方法是将少量颗粒肥覆盖于土层，或使用3%液态肥每月浇一次。

对于观花盆栽，winter season should add phosphorus and potassium fertilizers. These include plants like Sempervivum, Camellia, Chrysanthemum, Meihua, Waxflower and Hibiscus. Adequate phosphorus promotes large flower buds and vibrant colors or fragrances. Potassium helps increase the cold resistance of plants. Use solid phosphorus-potassium fertilizers or liquid ones like potassium dihydrophosphate every two weeks during flowering periods.

For fruiting pot plants in winter, it is necessary to add more phosphorus fertilizer for their growth after fruiting. Plants such as Citrus aurantium var., Momordica charantia L., Cinnamomum verum J.Presl., Annona muricata L., Diospyros kaki Thunb., Syzygium aromaticum (L.) Merr.et.L.M.Perry require adequate amounts of phosphate nutrients for next year's flowering and fruiting.
