Consulting Rosarian Tip of the Month



Ease back on watering mid-late in the month to begin slowing down the rose growth in preparation for the dormant season. Apply final fertilizers by the middle of the month. If vigorous basal growth appears in the last part of August, it is wise to remove these new shoots which may not harden off before an early damaging frost. Powdery mildew may begin to reappear in the last half of the month. If it appears in spite of preventative sprays, consider using organic fungicides such as GreenCure® or Serenade for control.
