3. Change the water daily
To keep the water in the vase clean and make it easier for the flowers to absorb water, you should change the water for the flowers daily. For intricate vases, you can change the water by placing the vase under the faucet and letting the water flow over.
Change the water for the flowers every morning, and in the evening, take them outside to catch the pure morning dew and add vitality.

5. Avoid letting leaves submerge in water
Before arranging, it's advisable to trim off the bottom leaves and avoid submerging leaves in water to prevent rotting and bacterial contamination. For flowers with soft stems like chrysanthemums, herbs, orchids... it's recommended to trim off any rotten parts of the stem each time you change the water.
Do not fill the vase with too much water, only fill enough to submerge the stems about 3-5cm; if the stems are fully submerged, the flowers are prone to bacterial rot. You can use certain chemicals like bleach, copper sulfate, silver nitrate... (at a concentration of 0.05 grams/liter) to inhibit bacterial growth, keeping the flowers fresh longer. However, for white flowers, avoid using silver nitrate or copper sulfate.
