ABS is sampling from address frames that are usually based, in part, on the USPS files. Although approaches for selecting samples of addresses for mail or in-person surveys have existed for decades, the surveyâs success depends heavily on the availability of a suitable address frame.
Water and water uptake are major factors in keeping cut flowers fresh. A process called hardening ensures maximum water uptake. It simply means placing the freshly cut stem in 110Â° F (43.5Â° C) water (plus preservative). Place in a cool location for an hour or two.
Cooler temperatures prolong flower life. Flowers stored at 41oF deteriorate three times faster than those stored at 30oF. Most flowers do not freeze at 32oF; generally the temperature must dip below 30oF (as low as 28oF) to freeze flowers.
