Here are some care and handling tips to enjoy your roses longer. A fresh rose can last for 10-14 days. Poor handling from the grower to the merchandiser will reduce longevity dramatically. 

For maximum vase life,  it is important that the flowers are conditioned properly.

Roses do not like to be out of water for too long of a period of time, so  as soon as you buy/receive them, remove the lower leaves and thorns that will be under the water line.  Place the roses in water with floral preservative and re-cut each stem diagonally 1 inch while under water.

This helps prevent air blockages in the stem. Repeat this process every 2 days. Fill a vase with cool water and freshly mixed plant food and transfer the flowers into the vase.
A rose stem is like a drinking straw, water will flow within 2 seconds. If you don’t put the stem in water immediately after cutting, air will block the water from going up the stem. This is especially beneficial for flowers with tight buds.
