Why Are My Flowers or Buds Turning Brown?
Brown flowers and buds can reflect normal aging, weather injury, decay, or pest damage. Notice whether the tissue is dry and papery or soft and spotted, whether gray growth or streaks are present, and whether the problem affects old blooms or fresh buds.
What this symptom means
The stage and texture of affected tissue help separate a fading flower head from buds that are rotting or being damaged. The hydrangea and rose answers below use those differences to guide a closer check.
What to notice first
- Older flower heads fading evenly versus fresh buds or petals browning
- Dry, papery tissue versus soft decay, spots, streaks, or fuzzy growth
- Recent frost, heat, prolonged wet weather, or root-zone stress
- Whether nearby leaves or stems show matching lesions or decline
