Answer: Lavender (Lavandula angustifolia) should be planted in a sunny location with very well drained, neutral to alkaline soil. You may mulch lightly over the root area in late fall with a bark mulch, but do not allow it to touch the stems or branches. In the spring, pull aside the mulch and be patient waiting for the lavender to begin to grow again. Trim it back by a half to two thirds, removing winter damage and making the plant fairly symmetrical. I hope you have planted one of the hardiest varieties such as Munstead or Hidcote, and that the drainage where it is planted is excellent. If not, it probably will not survive the winter in your cold climate. Here is some information you may find helpful.
Good luck wiht your lavender!
