Table 1

Effect of Sumagic drenches on growth and forcing characteristics of 11 hybrid lily cultivars grown at Clemson University in 1992. Amber, Delicious, Dimples, Montreaux, Mt. Blanc, Sindi and Stargazer were drenched March 30; Whitebird, Sun Ray, Sun Pearl, and Red Carpet were drenched on April 7. Bulbs were planted 3 per 6" standard pot on February 21. Height is measured from the soil line to the top of the plants; add about 6' for the pot.
