Answer: I'm not sure I understand your question, but it sounds as though you may have disturbed the roots of your lavender and it is showing signs of shock. If this is correct, your lavender should overcome the shock on its own and later this spring you can cut away the dead branches. Lavender is a rather hardy plant and should be pruned back annually anyway so I don't think you've done any permanent damage to your plant.
Best wishes with your garden!
