I was reading this article on Extending the Life of Cut Flowers and had a couple of questions.
As was also pointed out on How to keep my roses fresh?, you should cut the stems at an angle under running water to prevent air from getting in the stem. Alternatively, some sites actually suggest cutting them under water.
Q1: Isn't the stem exposed to oxygen when transferring it from the running water to the vase? Are you supposed to mitigate this somehow?
Also, the article lists some additives to help extend flower life.
Here's a recipe to add to the water in your vase:
- 1 tsp. Sugar - Feeds the plant which helps buds open and last longer
- 1/4 tsp. Bleach - Reduces growth of Bacteria and Fungi
- 2 Tbsp. Lemon Juice - Adds acidity which improves water flow to the stems
Q2: Using this recipe, can I premix a whole bottle and then add it as needed, or will the ingredients neutralize themselves over time?
Q3: Should this be done in conjunction with replacing the water every couple days? If so, should each fresh batch of water get it's own plant food cocktail?
