Rose Blooms Getting Smaller Each Year: Root Problem

Declining Bloom Size on 10-Year-Old Rose

Rose bush (10 years old) produces smaller blooms each year for 3 years.

Likely Root Issue

Progressive bloom reduction usually indicates root problems:

• Canker at base or on roots
• Girdling roots
• Soil compaction/drainage decline

Check

Examine base for lumps, swellings, or abnormal growth. If canker found, that's the cause. Otherwise, investigate soil conditions and root health.
