Environment change spurs early flowers in Bulgaria's historic rose industry

Bulgarian farmers were busy harvesting rose petals for their prominent oil this week, about a month previously than the historical standard due to climate change that has ushered in warmer and more damp springs.

Bulgaria, a European Union member nation in the southeastern Balkans, is one of the top worldwide manufacturers of fragrant rose oil that is also used in the cosmetics industry.

The very best increased oil is produced in its main Rose Valley where, historians say, the flowers have been cultivated as crops since the ancient kingdom of Thrace in the 5th-3rd centuries BC.

The first oil factory was opened in 1820 in the close-by town of Kazanlak.

The process of making the 2 to 3.5 lots of increased oil produced in Bulgaria annually is hard. For one gram of increased oil, more than 1,000 rose petals should be plucked by hand in the early early morning as vital oil material is greatest around 7 a.m.

Condensation forms each evening and clings to the rose, enabling the oil in the blossom to be at its finest, said Miroslav Terziev, an increased farmer in the town of Cherganovo.

Petals are also used for items consisting of increased water, rose jam, rose tea and even increased brandy.

The quality of the petals and oil is greatly depending on weather, with a mix of heat and humidity essential, stated Todor Nikolaev, primary technologist at the Terra Roza distillery.

He noted that with the current moderate winter season and a hot March, the roses started to bloom previously this year and the choosing season began about 3 weeks ahead of normal.

The month of May is rather rainy, so the flowers do not flower simultaneously, which permits a great selecting of the gardens. Low temperature levels avoid the evaporation of oil - the season is favourable for everyone in the production system.

Researchers state environment change over current years has caused plants to start flowering weeks earlier than previously.

We examined our archive from 1987 and found that the active, mass start of blooming of rosebushes was between June 10 and 20. And we have roses today that start flowering a month previously, said Valentin Kazandjiev, an agro-meteorologist at the National Institute of Meteorology and Hydrology in Sofia.

Kazandjiev stated farmers dealing with environment change ought to focus on innovations that reduce its impact, while scientists need to recommend various geographical zones for various crops every decade.
