What Is That White Fuzz on My Hibiscus Plant?

And on a new prennial in the new front garden by the porch?

It’s Mealybugs.

Here’s a pic of what they look like that I found online. I sprayed the tops of the infected plants with 50% alcohol and water, but it didn’t get the underside of the leaves on the plant outside–and we’ve had a fair amount of rain that will wash off the alcohol too.

Ugh! I’ve got the Hibiscus on the porch mostly under control. But not the front area plant that is NOT on a porch. So more spray this morning to include trying to get at the areas under the leaves.

Mealybugs, says the video below, can really be a plague in greenhouses.

And here’s more info on the Mealybug life cycle, if you are interested. There is a fly form involved too.

I have not yet dared to go around the house to check other plants. And there will be more rain today, which we still really need.
