Shrimp Plant problems — and how to fix them
Shrimp Plant (Justicia brandegeeana) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Whitefly and spider mite infestation
Glasshouse whitefly and red spider mite are the most common pests, especially under glass or indoors in warm, dry conditions; treat with insecticidal soap or introduce biological controls, and raise humidity to deter mites.
Leggy, non-blooming stems
Insufficient light causes long, weak stems with few bracts; pinch out shoot tips regularly and move the plant to a brighter position to restore a compact, free-flowering habit.
