Time to spray Leylandii for cypress aphids

[headgroundsman]

Early summer and every 6-8 weeks throughout summer months. I would say mid May would be the earliest worth starting. worth doing on youngish plants but not on more mature ones as unlikely to make much difference

Many thanks for that. Good guidelines I'll try and follow for the few customers of mine that have asked.

 

On a side note, for those who spray, what sort of money are you charging? I was thinking of basic charge £40 that will cover one knapsack full, then possibly £30 per tank after the first.

has anyone else noticed leylandi and similar browning off on the side that faces the wind, nearly all of them around our way have, we are quite near the coast, just wondering if it was just the wind or combination of wind and salt air.

 

 

Yeh, happens in exposed places anywhere. Can be either due to extreme cold winds and even sun scorch. Yet again, being exposed to any of the above shortly after trimming will make it worse.

I honestly have no idea what they are, but last year they left the tree at dusk and plastered themselves all over our lit windows. We had to keep the windows shut all the time.

 

I had sort of forgotten about them until I saw this thread.

 

Will have to do something about it before the summer, assuming they are still lurking in there somewhere.

 

 

Think I'd be felling mate. 😜

Yes I have noticed it.

I'm 20 miles or so from the sea but I did wonder if the winds we have had this winter had carried the salt here.

It is mainly on the softer tissue (regrowth from clipping) but not entirely. Not all of them have it either.

 

If it is environmental damage I decided it must be the wind as we have had very little frost this winter.
