Root rot, yellowing, and leaf spots are reported when conditions are unsuitable. Scale and palm aphids are also listed pests, so inspect the roots and fronds before assigning a cause.
How to care for windmill palm
A windmill palm needs bright indoor light and a free-draining pot. Keep roots out of standing water and avoid a long dry spell in summer.

Find a bright, steady position
Light and temperature
Start with bright indirect light indoors. The exact species tolerates full sun or partial shade, but strong sun through glass can scorch indoor palms.
RHS lists Trachycarpus fortunei for conservatory or warm-glasshouse use, and NCSU notes indoor overwintering for container plants. Protect a room-grown palm from cold drafts and radiators. No universal room target is established.
Check the mix, drainage and pot
Watering, drainage and repotting
Use a free-draining container and keep the root ball from standing in water. Indoor-palm guidance allows the surface to become slightly dry in winter, while summer watering should not leave the compost dry for long.
Use a well-drained loam-based or multipurpose container mix. RHS suggests repotting an indoor palm about every two years when pot-bound, but a large Trachycarpus container may need a condition-based decision.
Feed only during active growth
Fertilizer and active growth
After potting, wait roughly six to eight weeks before feeding. For an established indoor palm, RHS gives a feed every two weeks from April to mid-September. Use the product label for concentration.
