Why These Get Confused
- • These patterns can overlap in early scouting. compare visible pattern, progression, context, and the strongest confirmatory check before acting.

Key Differences
- • Stem Canker / Stem Rot: Stem Canker / Stem Rot often shows as the earliest visible pattern on affected tissue. Confirm spread pattern, tissue invasion, and local moisture pressure before treatment. Compare it against the strongest lookalike before acting.
- • Botrytis / Bud Rot: An internal flower rot pattern where bud interiors brown, collapse, or turn mushy before the outside fully shows damage, commonly driven by trapped moisture, dense flowers, and poor airflow in late flower.
- • Strongest differentiator: compare visible pattern, progression, context, and the strongest confirmatory check before acting.
Inspect Next
- • Confirm whether confirm the earliest visible pattern linked to stem canker / stem rot before assuming a single cause. appears on the earliest affected tissue, not only after the pattern has spread
- • Capture one macro image and one whole-plant context image before changing multiple variables at once
- • Compare this pattern against Botrytis Bud Rot before acting on the first impression
- • Document the most recent feed, irrigation, spray, or environment change that happened before symptoms started
- • Open the cola gently and inspect the interior for brown, gray, or collapsing tissue hidden beneath intact outer flower
- • Compare suspect flowers against healthy colas to identify internal spread rather than simple bruising
Before You Act
- • Confirm the strongest visible cue on the earliest affected tissue.
- • Open the linked issue guides before changing feed, environment, or sanitation strategy.
