Will laundry detergent kill blackberry bushes?

Laundry detergent can harm blackberry bushes if applied directly and in significant quantities, as it contains chemicals that can disrupt plant health. The surfactants and additives in detergents may damage plant tissues and alter soil pH. However, a small amount of diluted detergent is sometimes used in pest control, but caution is advised to avoid harming the plants. It's best to use products specifically designed for gardening to ensure the health of your blackberry bushes.
