Losing older, lower leaves steadily while the top keeps growing is completely normal on a lucky bamboo as the cane lengthens. It’s not a symptom by itself.
The fix
Only worry if it’s dropping leaves from the top or many at once. Otherwise let it be.
Other possible causes
Not a match? Compare the signs below to find the one you have.
A recent change or shock
How to tell
It started dropping leaves soon after you bought, moved, or repotted it.
The fix
Pick a suitable spot, keep care steady, don’t fertilize, and let it adjust over a couple of weeks. Many plants settle once conditions stop changing.
Overwatering
How to tell
Leaves yellow and then drop, and the soil stays wet for days after watering.
The fix
Ease off watering, check drainage, and inspect for rot in the roots if it feels soft.
Underwatering
How to tell
Leaves drop after the soil has been bone dry for a while. Watch for crispy leaf tips first.
The fix
If the soil is bone dry, water thoroughly, then check it more regularly so it doesn’t dry out that far again.
Cold drafts or temperature swings
How to tell
It sits in a draft, near a cold window, or next to a heater, and leaves fall after a cold snap or a sudden temperature swing.
The fix
Move it somewhere with stable, draft-free temperatures.
