Cultural differences - green vs. mottled leaf Paphs.

[shakkai]

Thanks for the responses. I just don't know what it is then...

The plants that I lost didn't rot, they didn't grow very strongly at all and eventually they started losing leaves.

As far as temps go, overnight lows are not very low - even in winter - but daytime highs are not very high, even in summer. Humidity is pretty high most all of the time. Air movement is quite good.

Maybe it was my watering? I was watering them all the same. Do they need to dry out faster than the mottled leaf types? Or stay more moist? Or is this just the same? I can easily adjust this with the size of the bark chips, I think, if that's what I need to do.

Maybe its just in my head, but it seemed odd that the only ones that I have that have died off and the ones that just don't seem to be thriving are all green leaved. Though as I said, there are a couple that seem fine: St. Swithin (young seedling), charlesworthii, and fairrieanum seem to be fine and growing as well as the others.

My barbigerum, and two other seedlings: Moustache and Susan Booth, are the ones that seem to be struggling.

Watering should be basically the same for all Paphs: stay moist but not wet. The strap-leaved kinds usually grow in larger pots though and thus should be grown in medium grade bark as opposed to fine grade.

Ross pointed out the use of fertilizer, and I agree that if you don't fertilize you could be slowly losing plants that way. So I also ask: do you fertilize?
