Before You Buy
When you're browsing flowers, Ovando recommends squeezing the head to see how firm they are. "The firmer, the fresher." You should buy flowers that are closed tight, since they'll open a few days later and last longer. If you're buying roses, Ovando says to pull off the first layer of rose petals, which are called packing petals.
Once you get the flowers home, cut the stems at 45-degree angle, says Ovando. And, don't let the stems touch the bottom of the vase — it'll make it harder for them to drink the water. If you can't change the water every day, TheBouqs recommends adding a couple drops of bleach to keep bacteria levels low.
