Hey there! I am a complete gardening newbie, and having some issues with my cherry tomato plants (two of them, in planters on my patio). As you can see, there is webbing on the plants. When Googling this, it seems like I might have spider mites. However, if you look at some of the other photos you can see what appears to be an actual spider (he looks too big to be a mite) on the underside of a leaf.
I have also had some drainage/fungus gnat issues, so I was trying to hold of on watering these for a while, which I read could drive out the fungus gnats but make the spider mite problem worse. I heard that you can physically spray and wipe off spider mites, as well as pruning the affected leaves. However, I didn’t want to move forward with that if these webs are actually from beneficial spiders that could be helping keep out other unwanted pests. Just looking for help from more experienced eyes - does this look like a spider mite problem or just your run of the mill beneficial spider that I should leave alone?
