Hi everyone,

My Sabal palmettos both have a scale infestation. I treated them with insecticidal soap but it didn't work.  Any suggestions on how to get rid of them?

I had to use Merit. Not a fan of using chemicals but had little choice it seemed. It worked.

A systemic insecticide drench is the only thing that has ever worked for me with scale.  Ace has good products. It may be the lighting, but the fronds are showing nutrient deficiencies also.

Nothing has worked and hardly any growth in a year. I'm afraid they won't make it. By now they should have grown out a lot more.

@Brad Mondel the weird thing is that the fronds look reasonably okay...despite apparently not growing out.  I've seen the highway Sabals planted in the spring, and usually by a couple of months they are growing out a few stunted fronds.  If they are short enough, can you get up on an a-frame ladder and see if there's a new spear growing?  If there is, mark it horizontally and check it in a week or so.  If it's moving, then the palm should eventually grow out okay.  We've had an unusually cool spring this year, at least here in central Floriduh.  A lot of plants I'd expected to be growing aggressively by April are just now getting moving.

I did see spears in both when I was spraying the scale with Insecticidal soap. I will mark them and see. I just don't get why they're so stunted when palmettos are usually so easy to get going.
