I have a couple plants that always seem to get spring sickness every year. One is Daveo Holman. Hasn't bloomed very much as a consequence. It has not spread to the 3 plants next to it. Think I will try Greg's systemic insecticide in the fall. Any special one you use? I have Bayer rose & flower. Think It is a fert, insecticide, fungicide combo. Maybe the fertilizer part wouldn't be good that late in the season?
