After winter, potted grapevines should be repotted, the old soil should be replaced, the roots should be trimmed after removal from the pots, and base fertilizer should be applied once. The fertilizer should be decomposed organic fertilizer. After that, pruning is required to cut off thin branches, leggy branches and cross branches, which can save a lot of nutrients and help survive the winter. After cooling down, move it indoors and control the temperature between 0-5 degrees. Or just take it out, dig a hole and bury it in the soil without watering during the period, so that you can survive the winter safely.
