I have grown three orange plants in a pot. I grew them from seeds. Two plants were growing very well while the third wasn't. It was between the two plants and so I thought it wasn't getting sunlight or nutrients.

So I moved it aside. Like I first put lots of water in pot to wet the mud. Then I carefully pulled out the small orange plant, then I dug a hole nearby and I put the plant in it. But now the plant isn't growing. Instead the leaves are dying. I spray water on its leaves daily but still the tiny plant looks like it's gonna die. Any help...

Any suggestions? I did the transplanting around 3 days ago. It gets 5 hours of sunlight. New shoots are coming off the remaining 2 plants from bottom, but this one isn't growing.
