How do annual salvia miltiorrhiza seedlings survive the winter?

Cover with film and straw.

In order to make Salvia miltiorrhiza seedlings overwinter safely, plastic film and straw mulching can be used. Before the soil begins to freeze, cover the salvia miltiorrhiza seedlings with a greenhouse or transparent plastic film, and cover them with a layer of straw to keep warm. This can effectively prevent seedlings from being hurt by cold weather.
