cut roses
While surfing the net, I came across this tip for cut flower solution:
One part "regular" (contains sugar) lemon- lime soda/ pop ( Sprite, 7-Up, generic) to three parts room temperature water.
Change after three days.
Seems to work. The liquid is staying clear. -one of the roses is still hanging in there ( delivered Feb 12 and today is Feb 22)
Of course, it helps when the flowers are in good condition when delivered.
