Since I’m in Ontario Canada, we have a pesticide ban. My approach has been to let nature take its course. Boxwood and euonymus develop have developed some issues with insects and diseases, some have died or are in the throws of dying. With an ever evolving change to our environment due to climate change I find myself doing way more research on the plants I’m using to ensure they are not susceptible to certain insects or diseases. Hybrids have been successful in many cases not to say that at sometime in the future that may not be the case. Trial and error seems to be a common path lately.
A memorable experience with plant disease management involved tackling a severe powdery mildew outbreak on a client's rose bushes. I removed the most affected leaves, pruned them for better air circulation, and applied an organic fungicide from baking soda and water. Regular monitoring and treatment were essential to control the mildew. This experience highlighted the importance of proactive disease prevention and organic solutions, shaping my approach to prioritize plant health through proper spacing, watering, and airflow.
