Flower food is a good thing. When you use it properly you know that your flowers will last longer.  If you’ve tested this theory, you know it to be a fact.  So, what is the deal with clear versus non-clear flower food?  The good news is that both work well and with equal efficacy.  Clear and non-clear flower food will lower the pH level of the water, nourish flowers, and provide optimal vase life.

So, what’s the difference?  Clear flower food uses an acidifier that results in a clear vase solution.  Non-clear flower food uses an acidifier that results in a flocculant. The flocculant appears as a white powder that settles to the bottom of the vase. These loose particles help reduce the pH of the solution and keep the water fresh. If you want a clean, crisp vase with no residue, clear is the way to go. However, if you process your flowers in black buckets, then it does not matter. Both formulas work in all water types; however, clear flower food may benefit flowers treated with hard water.

Our recommendation?  Always follow best practices when it comes to care and handling, and always use flower food.
