|all scattered in different locations the flowers last year got some kind of blight and looked terrible...treat this with?...they have come back and sprouted new shoots.
|Was it a blight disease or were they attacked by thrips? Thrips feed on the leaves and stems leaving ragged brown areas. These pests overwinter on the corms and the best way to control them is to soak the corms after digging in the fall. Lysol may be used; 4 teaspoons per gallon of water is the recommended rate. Soak the corms for 6 hours. Dry corms before storage. If you dip in the spring, plant the corms immediately after treatment.
