I'm not really up on shrubbery applications, hoping you guys can educate me a little. Have a large commercial property that I sub the shrubbery fertilizing and pesticide applications to...the oldest and most respected guy in town. Mainly needlepoint hollies, boxwoods, otto luchens, crepes and mamosas. Had an application 10 days ago, after 7 days 40 feet of petunias, and 2 adjoining boxwoods were dead... they'd been fairly healthy prior to that I think but I really hadn't checked them out thoroughly. Adjoining plants to them appear fine with no evidence of an infestation. No other plants on the site appear to have been adversly affected. Could an application have done this?
