Main highlights

To ensure that your fresh cut flowers or bouquet shine fresh and healthy in the vase long after purchase, you should use Floralife cut flower fresh! Above all, pay attention to the correct dosage of the freshening agent for flowers, a clean vase and knife as well as the correct execution
Place the contents of the bag in approximately 0.5 litres of tap water, which is in a clean vase. The powder for the flowers lowers the pH of tap water from between 6 and 9 to about 3 to 5 and increases the nutrient absorption of your flowers. Then cut the stems to the desired length with clean scissors or knife at a 45 degree angle. This allows the fresh cut flowers to absorb liquid and nutrients from the water better with the nutrient powder

Contents: 100 packets of 5 g for 0.5 l of water
