San Diego Rose Buds Shriveling? Rose Midge Is the Prime Suspect

San Diego roses put out many buds that start to open but then shrivel and won't open.

Rose Midge

Lays eggs at bud base in early spring. Larvae feed inside, preventing opening. Look for pinhole at bud base. Frost unlikely in San Diego. Apply rose insecticide.
