Diagnosis
Diagnose: Camellia Bud Drop
Use these observations to decide what to check next.
The timing and scale of loss separate the main causes
Scattered smaller buds dropping from a heavily budded, healthy shrub can be natural thinning. A sudden wave after cold or heat supports temperature injury, while gradual loss after drought, persistent wetness, or slow brown-tipped buds points to moisture, roots, site conditions, nutrition, or bud mites.
