We typically harvest your flowers within 24 hours of delivering them to our pick up locations making them much more fresh than flowers you can buy in any store. Our flowers typically last about a week, but some varieties have shorter or longer vase life. Tulips, daffodils, lisianthus, snapdragons, sunflowers - when harvested at the right stage, can last almost two weeks. Zinnias, dahlias, poppies, sweet peas and some other varieties typically last 4-5 days. We grow over 50 varieties of flowers, and each flower has its own unique habits and proper post harvest treatment. There are books written about this, no joke! Our best recommendation is this—- place your bouquet in a very clean vase, with clean water. Be sure to remove all leaves and extra foliage below the water line. Only stems should be in the water to keep it clean. Change the water every morning when you have your coffee. Bacteria build up in the water speeds up decay of flowers. You can snip 1/2 inch off stem ends every few days so the stems take a fresh drink. Also, keep your bouquet out of direct sunlight and extreme heat as this will also shorten life. Most of all, enjoy the bouquet as it ages and changes! Notice how some flowers continue to open and others do not. Notice how some colors fade as they age, sometimes very dramatically. NOTE: We stand behind our product, and since flowers are highly perishable sometimes things happen. If you bouquet dies within a day or two of pick up something went wrong! Send us a pic on email to info@csflowerfarm.com and we will schedule a time for you to come to farm and pick up a replacement bouquet.
