Data from the Bulgarian National Institute of Meteorology and Hydrology reveals that in 2024, the onset of rose blooming commenced nearly a month earlier than the historical average, which is typically observed between June 10 and 20.

This warming trend has direct implications for agricultural practices in Rose Valley, impacting both the timing and quality of rose-derived products, crucial to Bulgaria's economy and cultural heritage.
