Anthurium brown spots

Brown spots need texture and location checks. Dry window-facing spots, soft spreading lesions, and pest speckling point to different next steps.

For anthurium, adjust the diagnosis around this plant profile: Anthuriums prefer airy roots, bright filtered light, and steady moisture. Yellow leaves, brown tips, and weak blooms often trace back to watering, mineral buildup, or low light.

How to confirm it

Check whether spots are dry and tan, soft and spreading, or tiny and speckled.

Notice whether damage is strongest on the window-facing side.

Inspect undersides and new growth for residue, dots, or webbing.

Check whether the mix is chunky and oxygen-rich instead of dense.

Inspect flowers and new growth for thrips.
