Winter damage: privet

The first two weeks of March were very mild here, spurring some plants on to make early growth. Fresh growth on privet (Ligustrum ovalifolium) was particularly noticeable. But then, the third week of March brought a week of frosts and freezing winds.

It was at the beginning of April that I started to notice wilt and blackening on privets. My first thought was that it must be cold damage.

But then I wondered whether it might be something worse. It seemed the more I looked, the more I found wilting shoots of privet. I found them on all ages of bushes – from last year’s cuttings to gnarly old hedge plants – and on plain and variegated plants. I found them at the bottom of bushes and at the top; on plants that were pot grown, and plants in the ground. You can see in the pictures that one shoot would be wilted whilst its neighbour seems to continue in rude health.

In the end, it is the fact that the problem is so widely spread, especially that it is in pot grown cuttings as well as plants in the ground, that makes me think it must be cold damage.

For now, until I am sure that winter has finally gone away, I am leaving the dead shoots on the plants and will trim them over when better weather finally arrives.
