Paph Adam Hausermann x Duncan York seedlings: one thrives while the other falters

Paph (Adam Hausermann 'York' x Duncan York 'Good Show')

     When I purchased this paph cross in July, I was happy to discover that I had two separate seedlings in my pot, one slightly larger than the other.  In the 4 months since, the larger seedling has thrived, while the smaller struggles for survival. 

     Both seedlings shed one leaf each.  However the larger plant has since grown one new leaf, and is now growing another.  The smaller seedling is still struggling to push out the one new leaf it was working on when I first received it.

Paph seedling lost its roots, new root tip showing

     The reason for the disparate growth success lies in the roots.  The larger plant had two roots to begin with (while the smaller one had 1) and it grew two more roots over the last few months.  

     The smaller seedling, on the other hand, lost the one root it had.  My best guess is that the root died after snapping near the orchid's base soon after I first repotted it.  Both orchids were quite shaky in their pots due to their relative lack of root mass, and while adding supports helped stabilize both of them, I think I added them too late to help seedling #2.

     The rootless seedling does have one new root budding from its base however, so it still has a chance to survive.  I repotted it more securely back into its original pot.  The orchid will probably lose the lowest of its leaves before the new root can grow enough to support the plant.  Hopefully the other two leaves will hang on long enough for the root system to recover.

  1. Hope the second seedling survives. Since it has no roots maybe careful misting the leaves will help it to get some moisture so it doesn't get all wrinkled. Fingers crossed.
