The whole life process of garden spruce is inseparable from water. Although the evaporation in winter is small and the water demand is relatively small, it affects the cold resistance of garden spruce and its growth and development in the coming year. Therefore, spruce, especially newly planted spruce, should be irrigated with winter water at the beginning of 1 1. That is, "irrigation with frozen water", after irrigation, a mound is cultivated at the root of spruce. This not only supplies the water needed by the tree itself, but also improves the cold resistance of spruce.

Spruce planting should be pruned.

According to the different application purposes of garden spruce, correct pruning can not only adjust the tree shape, but also coordinate the relationship between aboveground and underground parts, promote flowering and fruiting, and eliminate pests and diseases. This work can be completed around the "winter solstice". If the quantity is large, it can be extended to around the Spring Festival. According to the growth characteristics of spruce, the dead branches, weak branches, pests and diseases should be cut off together, and the overgrown branches should be properly retracted to improve the ventilation and light transmission conditions inside the crown and cultivate an ideal tree shape. For larger wounds, drug disinfection and lead oil protection should be used.
