When will the grape seedlings be unearthed?

Grape seedlings unearthed in March and April in spring. At this time, the climate and temperature have stabilized, and excavation is conducive to germination and growth. The excavation time must be controlled well, not too early, otherwise the bud eye will germinate ahead of time, and the temperature instability will easily frostbite the bud eye. Even if it is unearthed too late, the bud will grow in the soil and be easily knocked out when it is unearthed. It is best to excavate in two times, the first time at the end of March, removing two-thirds of the soil, and the second time at the beginning of April, all excavation.
