Troubleshooting
East Indian Lemongrass problems — and how to fix them
East Indian Lemongrass (Cymbopogon flexuosus) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Brown, crispy leaf tips
Caused by drying out, cold draughts, or dry indoor air. Keep soil evenly moist, raise warmth and humidity, and trim damaged tips with clean scissors.
Frost damage
Any frost blackens and kills top growth; the crown rarely survives a hard freeze. Move pots indoors or mulch heavily before the first cold snap in marginal climates.
Thin, floppy clumps
Insufficient light or nutrients makes stems weak and pale. Move to full sun and feed regularly; cut back leggy growth to encourage a denser base.
Crown or root rot
Waterlogged, poorly drained soil rots the base. Plant in free-draining mix, never leave pots standing in water, and reduce watering sharply over winter.
