It might be poorly rooted and trying to get some leaf growth to gather enough energy to root. Make sure that the soil is not too moist or too dry, as this will inhibit rooting.
Make sure to let the soil dry out down to about 3 or 4 inches between watering, or even more! Not enough water is much better than too much water.
Unfortunately, your images did not come through so I am unable to see the state of the soil. If it is too compact, you may need to loosen it up. Earthworms can do this without disturbing your roots.
