Selecting healthy plants and planting them in suitable growing conditions is the first step in preventing pests and diseases on native plants in Kentucky. Plants should also be checked for signs of damage from pests and diseases on a regular basis. If a pest or disease is found, it must be identified so that the proper method of control can be implemented, such as the removal of infected plant parts through pruning or the application of an organic insecticide or fungicide (a mix of mild liquid soap and water).
