Regular household bleach is very short-lived (+/- 4 hours) compared to commercially available slow-release chlorine tablets (about 2-3 days). Marjoram, mint, parsley and oregano showed leaf yellowing and leaf abscission when exposed to ethylene while sage, thyme, basil and rosemary were minimally affected. Slant cuts will keep stems from lying flat on the bucket bottom and increase water uptake. If no commercial preservative is added to the water, it is at least necessary to use clean buckets and clean water. For example, fluoride in fluoridated municipal water is very toxic to flowers such as gerbera, gladiolus, and freesia and significantly reduces the vase life of these flowers. Basic postharvest handling recommendations have been developed for almost 300 cultivars over the years. I recently visited a grower that released high rates of Cryptolaemus larvae in a test area in week 15 to see if they could get ahead of their problem MB this Spring (300 larvae/m 2 /week for 3 weeks).
