Knockout Roses only bloomed once
Comments (13)Probably fall is not the time to apply granules. I am not an expert on this, but I believe the recommendation is to apply granules at bud-break in spring. The midge pupa overwinter in the soil in cocoons. Only a small percentage survive winter and emerge as winged adults, which fly up to lay eggs on the new shoots. These hatch into tiny maggots which do the damage. There are several generations per season, each larger than the previous. After feeding for a couple of weeks, the maggots drop off to pupate in the soil, at which time they are vulnerable to insecticide in the soil. You can also spray the top growth to catch the active larvae. Recommended chemicals are imidacloprid for the soil and cyfluthrin for the spray. These names appear in the fine-print active ingredients, regardless of brand names. "Merit" is a brand name for imidacloprid....See Moreonce blooming roses
