Anthurium brown spots

Dry exposed patches can follow strong sun. Silver scars on new leaves or flower spathes with tiny black specks call for a thrips check. Brown color alone cannot distinguish a disease from injury.

If spots enlarge or look wet

Separate the plant and keep foliage dry. Remove severely affected leaves with cleaned tools and avoid splashing between plants. Ask a local plant diagnostic service about rapidly spreading lesions rather than selecting a fungicide by appearance.

Check the root ball if spots also accompany whole-plant wilt or yellowing. Empty runoff and inspect collapsing roots; an anthurium needs a mix that retains moisture while leaving air around its roots.
