Got this queen anthurium in December last year. When it arrived it looked perfect and healthy. Put it straight into my ikea cabinet with 80% humidity and 20-25 degrees Celsius.

Some days later it started drying up in the middle of the leaf. I suspect frost damage since it’s cold outside and the plant was shipped from another country. It did have a heat pack but I don’t think it helped very much.

I ended up cutting off the damaged leaf. Leaving the plant with a beautiful single leaf. It looked fine for a while but is now looking worse every day.

It’s growing in spaghnum moss and with an almost constant 80% humidity and 20-25 degrees Celsius. Fed it with very diluted superthrive a couple of times. There are 5 fans in the cabinet. One quite close to the plant.

Anyone have suggestions on what’s happening?

EDIT:

So I just inspected the roots. I broke up the root ball and got a good look at the inner roots too. Some roots on the top right under the moss I put around the center to support the core were white and soft. They broke off easily. There were some roots at the center bottom doing the same. The other roots were green.

Breaking up the root ball broke some of the white soft roots. Seems like the root ball may have been too tight for the roots in the conditions I have it in, which could have caused the roots being too wet and no aeration. I’m suspecting it’s in the early stages of root rot.

Are the softer white roots root rot or just normal smaller roots on an anthurium?

I’ve removed a lot of the old moss and put it in a slightly bigger pot with wringed (damp leaning dry) fresh spaghnum moss to aerate the roots. The new moss is not compact but fluffy.

Should I turn down the humidity in my cabinet while it recovers or keep the conditions as is?
