Care of cut roses and how to keep roses fresh longer is easy if you borrow a few basic tricks from the experts, the professional florists, (that would be us).
Step 1: Recut the stems. Use a sharp set of pruners and cut at a 45-degree angle, so there will be a maximum surface area for the stems to drink water through.
STEP 2: To improve the vase life of cut roses and to keep the roses fresh longer, immerse their stems in warm water immediately after cutting.
STEP 3: Add a packet of flower preservative.
STEP 4: Keep your roses out of direct sunlight and away from drafts to prevent drying out and wilting.
It is that simple, folks.
