Now is the Time to Identify and Control Japanese Barberry
Connecticut's woodland undergrowth is beginning to green. Unfortunately, much of this color is due to invasive Japanese barberry (Berberis thunbergii de Candolle). This thorny shrub dominates unmanaged wooded areas. Deer don't eat it and birds spread it by eating and dispersing the prolific red berries it produces each autumn. Japanese barberry quickly grows into large thickets that provide cover for mice and an ideal environment for immature blacklegged ticks - the very ticks that carry Lyme disease. In their early life, ticks are susceptible to desiccation – they need high-humidity at the ground level to thrive. Japanese barberry accommodate the high-humidity needs of young ticks by leafing out earlier than most native shrubbery, thus maintaining ground-level moisture by blocking drying sunshine.
