Cut roses are well preserved in winter.

After autumn, before first frost (the closer to first frost, the better), select a batch of fully developed buds from the last rose bud, cut them into flower-cutting branches, and cut them into oblique stubbles. Put the cut branches into a wooden box filled with sand, cover the bud with the branches upward, and press a layer of wet sand with a thickness of about 18 cm on the branches. Then put the sandbox in the basement or cold cellar without heated air for refrigeration, and check whether the sand is wet at any time.

After winter, whenever bright cut rose is needed to decorate the living room, you can take out the required number of flower branches from the sandbox, cut a short section above the old incision to form a new incision, and immediately immerse the cut flower branches in boiling hot water. At this time, you can see the buds gradually blooming, and take out the cut flowers after the hot water is completely cooled. Using this method, beautiful roses can be easily obtained even in winter.
