Start with adding warm water in a clean vase at about 100deg F to the vase and then add one tablespoon of sugar.

Get some white vinegar or apple cider vinegar and add one tablespoon of vinegar to the vase and completely mix the water well in.

The vinegar acts as an antibacterial agent while sugar serves as food.

Remove any leaves that would otherwise go below the water line.

Using a clean pruning shears recut the stems at 45-degree angle for maximum exposure so that stems can take good amount of water. If your shears are not clean use rubbing alcohol
or hydrogen peroxide to clean and disinfect the shears.

Add a copper penny to the vase. In the United States any penny minted after 1982 is recommended since these pennies are 95% copper and it’s minted.

The copper in the pennies act like acidifier which prevents the growth of bacteria.

Do not place cut flowers in direct sunlight. Normal room light is sufficient for flowers.

Change the water every other day and recut the stems each time and enjoy long lasting fresh-cut flowers.
