I planted a Jasminum Stephanense last summer in the ground. It seemed to have wintered well and was showing new growth till last week. From the past couple of days I noticed that some of the branches had turned brown and the new growth on these branches have dried out? Any idea what could have caused this? Now I see only a small branch is still green.
Is the plant dying? Is there anything that I can do?

Any advice is appreciated.

Thanks in Advance
