Heat is the enemy
Eastern Oklahoma summers regularly push past 90 degrees, and humidity makes it feel hotter. Cut flowers lose water fast in heat, and a bouquet left on a sunny porch or in a hot car can wilt in an hour.
At home, the basics matter most. Change the water every day or two. Trim a little off each stem at an angle. Keep the vase away from sunny windows, stovetops and air vents. Remove leaves below the water line so they do not rot.
For deliveries, give the florist a phone number for the recipient so the driver can call ahead and avoid leaving flowers on a hot porch. For outdoor events, ask about sturdy flowers. Check the NWS Tulsa forecast (opens in a new tab) when planning.
