Maintenance and care: YishelyR Roses are hand-selected and carefully preserved to enhance their natural beauty. Your gift will last 2 ½ years or more with proper care. Keep your gift away from direct sunlight and excessive heat or humidity. Do not water your preserved rose arrangements. If you decide to store your preserved flowers in a sealed enclosure, they'll last even longer up to 3 years! Open your gift carefully. Natural roses every day change the water to ensure that bacterial growth doesn't damage your flowers. Fill the vase with fresh water, more flower food, and the right amount of bleach. Trim the stems of your roses and arrange them in the vase once more. Keep the roses cool. Display your arrangement for ultimate enjoyment!
