Great question! First, a little background:
Flower food packets typically contain three ingredients: citric acid, sugar, and....bleach (yes, it's true!). Plants do produce sugar during photosynthesis, but when they're cut, their food lines are as well. So they need a little bit of food to bolster their buds!
The best part is that you likely have these ingredients in your kitchen! Here are several solutions to replace the flower food:
- Apple Cider Vinegar & Sugar: Add a teaspoon of ACV and a teaspoon of regular sugar to the water. The vinegar kills the bacteria so your flowers will thrive.
- Lemon Juice & Bleach: A teaspoon of lemon juice, a teaspoon of sugar and 3 drops of bleach is another solution to keep flowers healthy. Or 1/4 teaspoon of bleach alone per 1 liter of water. Bleach may sound extreme, but it's a part of commercial flower food recipes and helps keep your stems free of bacteria.
- Lemon Lime Soda: One part Lemon-Lime Soda (Not Diet- the flowers need the sugar) to 3 parts water. The soda has both the acid and sugar needed for the flowers to live their best life!
