Sudden Leaf Drop on Healthy Rose: Root Zone Investigation

Your healthy rose suddenly dropping clean leaves (no spots, good water/sun) points to a root zone crisis—something has severed the water/nutrient pipeline.

Root Zone Culprits

• Animal damage: Voles, mice, rabbits gnawing roots
• Crown gall: Round, golf-ball growth at base or on canes — bacterial, fatal
• Root disease: Phytophthora, nematodes — often invisible until collapse

Diagnostic Steps

1. Gently excavate base — check for gnawing, galls
2. Inspect all canes for galls (can be above ground)
3. If gall found: REMOVE AND BURN entire plant — bacteria persist
4. If animal damage: Hardware cloth barrier, trap

If Neither Found

Sudden weather shift (heat wave) can trigger temporary leaf shed. Monitor for 1 week. Report back if no resolution.

Clean leaf drop on a healthy rose is never "nothing"—investigate the roots immediately.
