I have an anthurium that's at least 10 years old so would not like to lose it. Until this month it's been a low-maintenance plant. Last month we went on vacation and, from looking at other websites, I know I did 2 things wrong: I let it sit in the sink of water for a week, and the temp may have gone below 40°. So now it has wilting leaves, turning yellow, dying flowers on some stalks.
I don't know what variety of anthurium this is. It has gotten tall & leggy with leaves only on the top third, one flower at a time on each stalk. The blossoms are pink/mauve.
I haven't repotted it in 5 years & it looks like thereis soil only on the top.
So I'm guessing the 1st thing to do is let it dry out & repot it. Any ideas what next?

it needs to dry out!!!! and yes, repot it (sounds like it's way overdue for it).

if it's that long-standing it should survive...just let it dry out and repot it and then wait a couple of weeks before watering it again...

good luck!

joclyn gave some good advice.

(As an aside, the plant has become tall and leggy because of having access to so much water.)
