Severe cypress die back!

[Old Mill Tree Care]

I've Just arrived at an annual hedge cutting job to see this. I've trimmed them every year for the last 8yrs.

Last year there was minor evidence of drought stress and the previous two years I saw some aphid damage.

I'm amazed at this and can't see an obvious reason but I've got a suspicion.

 

Has anyone else encountered this?

That or the harsh weather we've had over the past year

I've had it happen to me , I was putting down to been to hard on the cutting , it's not all my doing os.

Over trimming and at the wrong time of year. I do my regular hedges in March and April, that way they look nice for the summer and put on some growth which protects them from windburn during the winter.

If I get any hedge work come in at this time of year I'll give em a light once over then advise the client to have them done properly in the spring.

Also there are a lot if wasps flying around it but no evidence of a nest inside.

Exactly this . I once partially trimmed a castlewellan late in the year and the only part that showed these symptoms was the part I had trimmed

Most likely a combination of regular hard faced clips and the soft fleshy regrowths being heavily aphid attacked because of the so sof new shoots. it is an increasing problem and there is only one way to deal with it (naturaly) and that is to not be so tight on the clip. That has a downside in that the hedge eventualy becomes very wide, and the leylands cannot be "restored" like a Yew beech or Thuja hedge

Dose anyone have experience in using rose clear or something of the like to help prevent the aphid or slow down aphid attack on conifers or is this just a myth?

I would think soapy water would work too
