Hello all! My wife and I recently went on a trip to Europe for 2 weeks and I had my sister watering my plants. I believe I had her watering them a bit too frequently and my lavender plant ended up with powdery mildew. I have been spraying it 1-2x per week with neem oil, however it seems to have decimated the lower half of the plant and it continues to ascend. Should I just keep spraying it weekly and hope for the best? Maybe cut off all of the remaining leaves/stems and help it restart?
