Keep the fresh cut flowers your neighbour or sweetie gave you lively for as long as possible by adding this DIY solution from the Brooklyn Botanical Garden to the water:
Mix 1 teaspoon sugar, 1 teaspoon bleach, and 2 tablespoons lemon or lime juice in a quart of warm water.
Having noticed that the packet of preservative that comes from some florists was indeed some sort of magical elixir of flower happiness, it's nice to have a DIY option. Additional tips from Cottage Living magazine include cutting the flower stems every few days at a 45 degree angle with a sharp knife or pair of garden shears. Scissors crush the capillaries in the stems and hinder the intake of water. Photo by PleasantPointInn.
