Speckled Rhodie Leaves
"David J Bockman" wrote in message ... Check the undersides of the leaves for evidence of Lacebug poop... will look like black pepper. I agree with David that what you describe sounds like the results of a lacebug infestation, but winter is an unusual time of year for this to show itself. Lacebugs are typically present during the growing season, but winter stress from excessive cold (like you experienced several weeks ago) may have amplified what was overlooked earlier in the season. Eggs overwinter on the underside of the leaf close to the midribs. Hosing off or applying an insectidicidal soap is your best control method. Will need to repply when they hatch in May and again in late June or early July. Rhododendrons grown in much sun seem to be more prone to damage from lacebugs than those grown in a cooler, shadier position. pam - gardengal "Anonny Moose" wrote in message ... A few of my rhododendrons' leaves are showing a loss of color this winter. They look almost white with green speckling. Anyone know what this is and what I can do for it? Thanks. Karen portland, or |
