Dear Slipper friends,

Some weeks ago i got some flasks of diverse multifloral paphio species from Taiwan. they were roughly one week in transit before they arrives.
They were a little shaken and bruised, so i deflasked the problematic ones immediately.
Now, 2 weeks later, i managed that nearly all survived, but the leaf tips turned yellow on some with brown tips:confused:

I grow them in a propagator measuring 1,3m x 0,6 m, the temps range between 28 and 19, humidity is between 60-70 % and the get watered with RO water, so far i havent fed them. To keep the humidity up (the fogger hasnt arrived yet) i spray them 5-6 times a day. A little fan is blowing constantly above the leaves...

what could be the problem of the leaf tips turning yellow?

I hope someone can help me out here, i dont want to loose these precious flasks:(
sorry i cant up a photo for now, camera is in maintenenance

Greetings from Germany:heart::heart::heart:

It is probably from stress being in transit for so long. I would cut off those tips and apply cinnamon and then keep a watchful eye on them.

You are keeping them too wet.

Don't water as frequently and stop spraying them. Also, don't have the fan blowing on them.

I agree that you should also cut the browning tips with a sterile tool and apply cinnamon.

Yes you are growing them too wet. Let them dry out a little in between.

Many Thanks for the replies,
and i thought it wasnt humid enough for them, and the leaf tips are drying up (looks like it though...)

i try to keep them a bit drier from now on and see if that helps
