How to care for delphiniums in your home:
Cut any leaves or foliage that will fall below the water level. This will keep the delphiniums fresh for a longer period of time and will give them a cleaner appearance. It will avoid rotten leaves and harmful bacteria in the water.
Cut the stems at a 45-degree angle to promote water intake.
Rinse the stems thoroughly before placing them in a vase, again to avoid any harmful bacteria from seeping in the water.
Change the water every 2 to 3 days . Place the vase in a cool area and out of direct sunlight.
