showed me how to treat the boxwoods, left me with some chemicals and a written plan to treat my boxwoods. We have been faithfully treating our boxwoods weekly as he suggested. I’ll share his plan at the end of this post. Brian is THE man!
Mix the chemicals in a 1-gallon or 2-gallon pump sprayer:
1. Daconil: 1 oz/gallon of water
2. Tebuconazole: 1 oz/gallon of water
These chemicals can be mixed together in the same tank. In the case of a 2-gallon sprayer, you will mix 2 oz of each chemical in 2 gallons of water. Spray the boxwood to the point of runoff, covering all sides of the shrub. These fungicides are safe and will not harm the shrub or other plants in any way. You can’t spray too much.
Boxwoods should be sprayed every 21 days during the months of April-October. No spraying is required from November-March. (Note: since I had infected boxwoods and it was so close to the end of the spraying season, Brian advised that we go ahead and spray weekly.)
Thank you, Brian! I’ll be making you a homemade thank you treat very soon!
