Decomposing pieces of leaves and thorns, dust and other pollutants from the air, contaminate the vase water. All this decomposition, organic matter and molds make the water cloudy and dirty and can be a food source for microorganisms. The vascular bundles in the stem, required for absorbing water, can become plugged by this contamination. This contamination is especially evident on the water surface. When the water level drops, the unsightly scum remains on the side of the vase, dries up and becomes visible.

Keeping the vase water free from decomposition elements is the first requirement. The food supplements and acid regulators in Chrysal cut flower foods help flowers to develop in a natural ‘plant-intact way’ and the vase water is not contaminated by all the decomposition products of the stem, as is the case with only tap water. For the best results, always add the right amount of flower food to the indicated amount of water by following the instructions on the back of the pack.  

It is also essential to get into the habit of cleaning containers and vases immediately after use and then again before use, no matter how clean we think we are, as often dust etc. can form whilst being stored in cupboards, on shelves etc.  Use ‘soft’ cleaning products that are not aggressive for cut flowers. For both florist and consumer it is essential to remove all dirt and contamination by thoroughly cleaning anything you intend to display your flowers in.
