Insect Damage to Dwarf Cherry Trees (Zone 6b)
I planted some dwarf cherry trees this spring near Windsor, Ontario / Detroit, MI. Of the three I planted, two are doing very well however the third has been attacked by some sort of unidentified insect from what I can tell.
I sprayed the plant with soapy water a few times and the damage seems to have been halted.
Can anyone identify the damage and suggest a pesticide or other mitigation measure I should take? I am a novice with fruit trees so I don't know where to start.
Thanks, and happy gardening!
