This tree was clean on Monday, and I didn’t pay much attention to it when I was back in town, other than to think it was looking slightly puny…leaves seemed like they weren’t quite getting enough water, so I watered it in the afternoon and didn’t pay it any closer attention. Friday evening, some black spots caught my eye and it was clear this maple was loaded with aphids. Wow!
Pay close attention every day, and get to know your trees well enough that if a glance tells you something might be just a bit off, investigate quickly!
This tree got nuked with Malathion, which will have been rinsed off by the time you read this.
Take it a step further. If aphids are popping up in this maple, are they hitting other maples? Let’s take a look at the maple a couple benches down…
Fortunately, they’re easy to kill, but easy to return. Stay vigilant my friends.
