Fungus gnats
Signs: Larvae damage fine hair roots in wet peat medium; adults hover and breed continuously; plant may yellow or stall
Control: Drench medium with Bti (Bacillus thuringiensis israelensis) solution; yellow sticky traps catch adults; refresh tray water regularly
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
