Choose juniper plants that have been reported to be disease-resistant. Check with your local university extension office or your plant purveyor for a list of hardy juniper plants.
Plant your juniper plants so that there will be plenty of air circulation around them -- take into consideration how big they will grow when planting; there should be a couple of feet between each plant when fully grown.
Control blight by watering your juniper trees and shrubs in the early morning so that they can dry in heat of the afternoon.
Follow directions when fertilizing your juniper trees and bushes, using caution so as to not overfertilize, which can cause the ends to dry out and form blight spots.
Prune any diseased branch tips as they occur, especially during the drier summer months, which can cause the blight to spread more easily. Discard or destroy any trimmings,
