| I planted 5 green mountain boxwoods fall of 2004 and covered them with burlap last winter. I did not cover this winter and some leaves are turning yellow. Is this normal or should I cover them again. They are getting southern full sun exposure. |
| Boxwoods can discolor in winter either due to sun or wind exposure causing them to dry out. A southern exposure is difficult for them because it reflects heat back off the building. I would use burlap, yes. Also make sure each fall that the soil is kept slightly damp until it freezes hard, that way they will go into the winter fully hydrated. |
