Why are new anthurium flowers shriveling and dying

Question

Why are new anthurium flowers shriveling & dying shortly after they appear? Plant is indoors in front of north-facing window and never receives direct sunlight.

Answer 1

The most likely cause is that the soil is staying too wet, and root damage is starting. Anthuriums are more fussy than many common houseplants. Test the soil for moisture near the bottom of the pot, not just the surface of the soil.

Using a moisture meter, the meter should read 1/2 to 3/4 of the way between dry and moist.
Another thing to try would be to move the plant to higher light, like an east or west window. Sometimes I’ve had to move plants around several times to find each one’s “happy spot.”
