Cut flower life is greatly extended and avoids the necessity to frequently change water.
In a clean vase, dissolve the contents of one sachet in ½ litre of water (approx 1 pint). Carefully re cut the flower stems diagonally with a sharp knife never break, crush or use scissors. Remove lower foliage up to the rim of the vase, and then arrange your flowers. Always wash your hands after handling cut flowers.
