The invention discloses a petunia rejuvenation agent and a use method thereof. The petunia rejuvenation agent is composed of gibberellin, triacontanol and brassinolide, and the weight ratio of the three components is: 10.0~20.0:1.0~2.0:0.5~1.5, the preferred ratio is 15.0:1.5:1.0, the three components are calculated according to the weight ratio of 100% purity. When used, it is diluted at a concentration of 15-25 µg·L-1, and then sprayed on cut and trimmed petunias. The operation should be carried out in the evening on cloudy or sunny days. After spraying, it is guaranteed that there will be no rain within 24 hours, and artificial sprinkler irrigation will not be carried out during this period.
