Fungus gnats

Signs: Larvae damage fine hair roots in wet peat medium; adults hover and breed continuously; plant may yellow or stall

Aphids

Signs: Small colonies on flower scapes in spring and summer; honeydew deposits; scape may curl or abort

Control: Gently rinse scapes with water; any aphids crawling onto the glandular leaf surface will be trapped by the mucilage
