Myhawthorn edge is covered in a sticky substance

West Yorkshire, United Kingdom Gb

My hawthorn edge is covered in a sticky substance .... what could it be and how shall I treat it ?




Answers

 

Could be honeydew, secreted by aphids. Spray with systemic insecticide to kill aphids and very dilute washing-up liquid a few days later to wash away honeydew otherwise you will get a sooty mould.
