Thanks for the quick reply and reference! Nasty looking but, not as bad as I feared.

How about the fine webs on my Azalea if I may ask? Spider Mites?

Webs look like spider to me and the galls are definitely….

Holy smokes! Yes looks like it’s probably spider mites to me. I always remove the webbing before it ever reaches that stage of proliferation.

That's what I did and separated it from the rest. Thanks

That's actually what makes me think it's spiders. I've never seen spider mites create a web that large and loose. Usually it's really thick and silky. I'm not saying they could never make a web that big but even my worst infestations never looked like that, and those trees were half dead

I haven’t had the misfortune of seeing a web like that on one of my bonsais. But on my neighborhood walks I have seen some HUGE spider mites infestations on neighbors’ landscaping plants. They seem to love dwarf Alberta spruce. I’ve seen them take over an entire 5 foot tall DAS and kill it over the course of a summer.

Not in my garden though!

Try a vigorous splash job w/garden hose. Coupled with a little hands-on removal, should be good to go......


.....maybe wheel up one of your dirt-bikes and give it a couple blips on the throttle......aftermarket pipes got some good flow!!!

Maybe a little sprish-sprish with insecticidal soap just to be certain.



Gall not really terminal, but hella' unsightly!!

Thanks friends When removing the webs there was a small spider cussing me so it may be a regular spider and not mite. Going to do the paper test and hose it off just the same. Maybe I'll take it for a ride @LanceMac10

I say anything spanning 2 branches is a spider.

Mites tend to web closer, like leaf to leaf or leaf to twig.

Follow up is it was just a regular small spider community and no harm done to either plant or spiders
