Troubleshooting
White Sails problems — and how to fix them
White Sails (Spathiphyllum floribundum) 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.
Drooping despite moist soil
Can indicate root rot from consistently waterlogged conditions. Remove from the pot, inspect the roots, trim any blackened sections, and repot into fresh well-draining compost. Ensure the pot has drainage holes.
Green spathes
Spathes naturally turn green as they age. If new spathes emerge green rather than white, the plant is likely receiving too much fertiliser or too much light. Reduce feeding and move to a slightly shadier position.
Spider mite infestation
Fine webbing and stippled leaves indicate spider mites, which thrive in hot, dry conditions. Increase humidity, wipe leaves with a damp cloth, and treat with insecticidal soap or neem oil, repeating weekly for three to four weeks.
