Like Abnshrek and Siege said, your pups are trying to establish a new root system. That will take some time and as you have planted them in pots, it should be easy to move them into the shade.
One thing I like to do with pups in pots before planting, is to dust the roots in mycorrhizae. It is making a huge difference for the pup in developing roots faster. There were pups I thought that were lost because I did not see any roots but apparently there were and mycorrhizae did its magic
