I had initially bought a 1 gallon pot of 4 Kentias from Etsy a few months ago. One of them died on me pretty suddenly, so I split the other 3 up and stuck this one in my office. It's starting to yellow - 

 

I did carefully detangle the roots. The nursery I bought it from has their own special Kentia soil, but I removed it and it's in a mix of Turface, reptile bark, and Fox Farm Ocean Forest potting soil at a 1:1:1 mix. 

 

My office gets a lot more light and is a lot warmer than my apartment was. Should I bring some fish emulsion or Superthrive (already read all the posts, already bought it) to help him out? The little frond in the back is more yellow than the rest, and he's still got some black spots from prior pest damage and shipping. He's definitely a few shades lighter than he was last week though. 

Sorry, i meant to post this in Palms In Pots 

I hate to bump my own thread but I could use knowledge and pointers. Otherwise I'm gonna have to call Phil at Jungle Music and buy some Belmoreanas 

Turface? As in the stuff used on baseball fields?

I'm not up to speed on your soil mix - and maybe it's what's recommended - but we've always used just regular planting/potting soil for the ones we used to grow. Sphagnum peat, perlite, & bark.

Others with better input may chime in....

Yup. Drains fast. Holds moisture. All that good stuff. Maybe it wasn't the best choice for a Kentia? 

How "warm" is your office? Howeas are not heat loving palms although I have trouble believing your office is that warm. What is the humidity? Indoor humidity can be surprisingly low in winter. I don't keep houseplants but I know my tropical container palms get really unhappy if brought indoors for more than a night. As for turface, I'm not exactly sure how that works as I haven't tried it. I'm shifting my potting mix to mostly coco coir. If you use only turface can roots dry out too much between waterings? Can you overwater with turface?

That might be it. I keep my relatively dark apartment around 68° and my office has to be in the high 70s with the curtains open. 

 

Turface is basically the same thing as the Seramis clay the European growers are using - it seems impossible to over water. Very fast draining, seems to hold moisture but doesnt get soggy to avoid root rot. Needs more watering than potting soil.
