Answer: I suspect that your tree is just going through a normal stress period after being transplanted. Trees and shrubs often do this, but they recover once the root system gets established. You can help it along by watering deeply once each week, all through the winter months. In spring you should see new growth. If you didn't build a watering basin beneath your tree when you planted it, make one now by simply mounding up a few inches of earth to make a circle beneath your tree. Fill the basin with water, allow it to drain, then fill it a second time. Do this once a week. Watering in this way will concentrate the moisture over the root ball and allow it to trickle down and wet the entire root mass.
Most trees and shrubs need about one-inch of water per week. If rainfall is sparse, water everything deeply once each week and they should be happy.
Best wishes with your pepper tree.
