The document discusses conditioning roses and other cut flowers. Conditioning involves treating cut flowers with a solution to prevent bacterial growth. It should be done every 3-4 days to keep flowers hydrated and prolong their longevity, which for roses is typically 3-10 days. Conditioning solutions contain nutrients, acids to lower the water's pH, and antibacterial agents. Common household items that can be used instead of commercial floral preservatives include clear sodas and mouthwash.
