I used Bayer Tree and Shrub fert and protector and did not have ONE aphid or scale on any tree this year.
I even fed the pines with it.

That is a systemic and is a great product to use before you have a problem.

A systemic takes time for the tree to take up through the roots to be effective. It isn't so good when you need something right now.

The tree pictured above has a very bad infestation and needs it right now.

Pick all the bugs off by hand and then spray with insecticide.

Absolutely correct. I started the Bayer at the very first peep of 2019. Still ending winter.
Prior to that, my olives had great pick-me-off scales to keep me busy in the summer.
2019? NONE. :)

Thanks Sandy! I have been super busy today, but only one maple looks bad I think. I get back with you. Heath

Oh crap. I just noticed needles turning white on one of mine. Will assume it's fungus and will spray with copper fungicide.
