Oleander Yellowing Lower Leaves: Normal Growth Habit, Prune to Renew

Oleander in 14" pot on deck blooming but lower leaves yellowing and dying from bottom up. Top has new branches and buds. Owner wants to nurse it before bringing indoors.

Cause: Natural Growth Pattern

Oleanders grow as "sticks with flowers on top"—lower leaves naturally drop as plant elongates.

Solution: Annual Pruning

• Prune once a year to force branching and fuller growth.
• Timing: Spring in cold climates; anytime in warm zones while actively growing.
• Cut back to desired height; new shoots emerge below cuts.

Critical Safety Warning

All parts of oleander are extremely poisonous to humans and pets. ~1/4 lb leaves (30–40) can kill a horse. Keep away from children, pets, livestock. Not palatable but dangerous if ingested.
