How Florists Keep Flowers Cool During The Heat

Wooo! It’s a scorcher out there, and it’s only going to get worse! I don’t know about you, but I can barely keep my lawn alive during this heat, and flowers — forget about it! So how is it florists keep such beautiful flowers all year long, even Sun - Heating Things up for Floristson deliveries?! Here are some tips our florists shared with us yesterday.

Tips For Keeping Flowers Cool In The Heat

  • Make sure the A/C in your delivery vehicle is in good shape and prepared for summer.
  • Make sure the delivery vehicle is cooled off before loading. via Lisa from West End Florist, Rome GA
  • Invest in a spare key so you can leave the car running while making other deliveries. – via Emily from The Enchanted Florist, Asheville NC
  • Check newly arrived flowers for improper temperatures.
  • Immediately prep and refrigerate newly arrived flowers.
  • Try not to move flowers in and out of the cooler while designing.
  • Make sure the temperature of your cooler is adjusted properly for your flowers.
  • Choose lighter colored delivery vehicles to help keep them cool.

Flowers and plants need to be kept at a certain temperature in order to breath and intake food properly. Keeping flowers at a consistent temperature is vital for reaching a it’s full vase-life potential. Low temperatures also slow down the growth of bacteria and other micro-organisms, which will extend the vase life for customers.

Before a flower arrives at your local flower shop, it has made a long journey. Starting with the growers, they are shipped in refrigerated planes or trucks to the wholesale level. Wholesalers keep these flowers in coolers until they are shipped to the florist, who also stores them inside a cooler. After all this refrigeration, you can see why flowers would get finicky once they are out of the cool. Florists do their best to maintain the right temperatures for their flowers.

How To Keep Fresh Flowers Longer During the Heat Wave

Growers, wholesalers and your local florist have worked hard to keep your flowers looking perky and fresh during the heat. You can continue this process in your own home to ensure your new flower arrangement last as long as possible.

  • Keep flowers cool – store them in a coolest room of the house when no one is home.
  • Keep flowers away from drafts and vents
  • Keep the temperature of your flowers as consistent as possible.
  • If your flowers came in plastic, remove this as soon as possible.
  • Keep your vase filled with water. Hot flowers will drink lots of extra water.
  • If your flowers came in a basket or other container with foam, add fresh water every day.
  • Remove any dead or dying flowers from the arrangement.

Remember, if you’re ordering flowers during the summer, or any time of year, always always always use a real local flower shop. Supporting local is so important. If you don’t know yours, use FSN’s handy Florist Finder to find a real local florist in your area.


  1. One of the most important things also to consider, it make sure that your flowers are given a good drink. Chrysal Professional #2 should be used by florists to condition their flowers and don’t forget to provide sufficient flower food sachets to your customer. Growers, exporters and wholesalers have all worked hard to get flowers to you in tip top condition by using a range of flowercare products (hopefully Chrysal), so make sure you keep this up!

  2. Thanks for the tips, Anne!
