Make sure to remove the stems as soon as you receive the roses.
Also, cut the leaves that are falling below the water line.
Always go for a neat vase, clean the container well before using it.
Choose a ceramic or metal vase instead of glass to help the flowers last longer.
Fill the vase with enough water, put flower food before you place your roses.
Like every other thing, flowers too need nutrients to look lush.
Provide flower food at regular intervals.
Keep your roses away from heat to make it last longer.
Too much heat or light will damage the delicate petals of your flower.
Lastly, it is necessary to change the water in your vase from time to time.
