Plum Tree Not Blooming: Sump Pump Flooding Roots

On May 8, a plum tree shows no buds after a wet winter/spring. Sump pump discharges at its base. The owner asks if redirecting the pump will allow recovery.

Waterlogged Roots Cause Failure to Leaf Out

Constant saturation displaces soil oxygen, causing root dieback. Without functional roots, the tree cannot support foliage. The sump pump is the likely culprit.

Recovery Steps

• Redirect sump pump immediately.
• Check viability: scrape bark on upper branches—green underneath means alive.
• If alive, it should leaf out once soil drains.
• Prune dead branches after leaf-out.

Time and drainage are the only remedies.
