Green aphids on Goat willow

[pablo sánchez]

Hello All,

Yesterday I found a very dense infestation of black flies and wasps underneath a mature Goat willow.

The tree owners have not being able to get closer to the tree (in the center of their lawn) for a month.

Big hassle for them. So they want to get rid of the tree!!

Calm down I say...

let's sort out the problem and save the tree!

 

It is probably a green aphid infestation.

But the canopy it is about up to 5 meters.

How to treat it? and what with?

 

any thoughts?

thanks

Pressure wash it from a distance with some detergent in the water. It's probably ants farming the aphids and wasps will eat them as well. Next Year put a grease band round the trunk to stop the ants climbing it

Those black flies are a kind of non-biting midge, similar to the st. Marks fly, to get rid of those, deep scarification on the lawn is needed
