Use a good commercial flower preservative in your water to extend life of your flowers
Do not place flowers in direct sunlight
Use a knife to cut the bottom of the stems at an angle. Do not use scissors as they clamp the stem.
Do not place flowers in drafty areas
Use 6-8 drops of Clorox Unscented Bleach per gallon of water
Do not place near heating or air conditioning vent. (This will cause flowers to dehydrate)
Make sure that you are using a vase that has been thoroughly cleaned. All leaves should be outside of the vase to keep water dirt and residue free
Do not place flowers next to fruits and vegetables. Some flowers are ethelyene sensitive (a gas emitted by ripening fruits and vegetables)
Replace water every 3-4 days, or as you see the water is turning cloudy and murky. The chlorine (bleach) treatment mentioned above should be useful to eliminate the growth of bacteria in the water.
Many ready made retail bunches contain netted flowers such as Gerberas, Spider Fugi's, and Amarylis to name a few. To properly handle these flower types:
Use both hands to carefully fold the bottom of the net outwards and then fold upwards. This is very important in avoiding petal shedding
NEVER pull up on the net. Petals will get caught in the lower part of the net causing them to separate and fall, rendering the product useless
