Early identification and removal of problems is essential. Entire plants infected with some virus diseases must be removed. Most of the fungi that infect brambles overwinter in old canes that were infected during the previous growing season. Cut and remove these canes to control these diseases. Thinning, proper watering and avoiding wounding canes help prevent disease.
Good drainage stimulates vigorous growth and reduces the impact of insects and diseases.
Avoid shady sites. Bramble diseases include anthracnose, cane blight, spur blight, septoria leaf spot, grey mold, powdery mildew, orange rust, crown gall, verticillium wilt and various virus diseases. Aphid and nematode control is essential in controlling several viral diseases.
