Place in water.
All flowers need water to flourish, but different blooms have different demands! Before you set them in water, check on their particular water requirements. Flowers with woody and semi-woody stems like roses, mimosas, lilies, chrysanthemums, and carnations tend to drink a lot. Place them in warm water filled to about 2/3 of your vase.
Soft-stemmed flowers like anemones, freesias, and ranunculuses prefer shallow water. You can place them in warm water filled to only 1/2 of your vase. Flowers with bulbous stems like daffodils, hyacinths, and tulips enjoy a bit of a chill, so put them in cold water up to 1/3 of your vase.
Set in a cool area
Most flowers prefer cooler spots away from direct sunlight. You can still put them by the windows to create a peaceful look for your home; just be sure that they're kept away from light and that they don't touch the glass. If you like having flowers as a centerpiece for your dining table or kitchen, see to it you put them where there are no fruits close by. This may sound unusual, but ripening fruits actually emit small amounts of ethylene gas that cause flowers to brown and age earlier than normal.
It's also best to keep them away from anything that releases or generates heat, such as air conditioning units, fire places, heating vents, radiators, or televisions - these can result in dehydration and early wilting.
Extra Care Tips
Change water and food
Water can collect dust and particles from your surroundings, while leaves and stems can break off your flowers and fall into your water. These elements cultivate an ideal environment for bacterial growth. So it's vital to change your water every 2-3 days. For best results, you can wipe the vase before you replace the water. Also, make sure to mix in fresh flower food to replenish your flowers' nutrients!
Re-cut stems
Whenever you cut flowers, you create a "wound" at the bottom of the stem. So flowers "mend" themselves by sealing the wound which shuts it off to water supply and drastically decreases their water intake.This is why re-cutting stems is important! It opens up your flowers' stems so they can absorb more water; plus, it helps clear away blockages and inhibit infections as well. Simply snip off about half an inch off the stem every three days and you'll be sure to lengthen your flowers' lives!
