Another Sedirea cry for help!

[Becca]

Well I saw the other post on help needed with a Sedirea and I didn't want to highjack the thread, but it reminded me I have been meaning to ask you all for help!

My little Sedirea japonica Minmaru for the project plant arrived in great condition. Potted in a small pot of sphag moss and it came in spike and has flowered. I have noticed that the leaves starting at the bottom, have been one by one, getting a wrinkled look but staying green, and when I gently tug on them they fall off, and like I said, it only happens one by one, so I have lost a total of 3 or so leafs since receiving it, with another one to be lost shortly. I am just trying to figure out if I am under watering it or over watering it I try and let it get almost dry in between waterings and watering is usually about once a week. Does anyone have any advice? I looked at the roots, and most I can see anyways as it is potted kind of like the traditional style for Neo's, and the roots look good. Some look dark, but they are firm. When the medium dries a bit the roots look dark colored, but once I water they get a green color to them.

Anyways, if anyone has survived reading my long cry for help I would really really appreciate any advice or help!

Thanks!
