Pesky mites

My huge lavender azalea, 5 ft in diameter and height, was turning yellow. Under the leaves were mites. Or so I thought. I sprayed it well with Malathion, top and under the leaves. Now the leaves are falling off. I hope it doesn't die. It's probably 15 years old. If it survives (branches) Should I feed and water it right away? It is now November in Tennessee. Also, the bush is abutting my brick house. Will this effect the pH?
Thank you for your advice.

Harvesting wisteria seed pods

Do seed pods need to dry to the point of bursting before harvesting the seeds or can can I break them open before then? If so, will I still need to dry the seeds? I have some that are sort of golden brown, plump & can hear seeds rattling inside & some that are a darker brown & flatter but turning beginning to turn golden (pic 1). Also, can I use pods collected from the ground? I believe the second & third pictures show the progression of the drying stages.

Spider shot web from truck cab top to my SUV cab top

I saw a spider shot a web from the neighbor truck top to my SUV top 70 yards away. It then from my SUV shot a web up to the tree top which was 60 yards away. I know it couldn't see what was in the tree from the neighbors driveway. So where was it going and how much web can it shot before running out ?

Black plum spots

This tree is 4 to 5 yrs old. We are getting fruit for the first time but the fruit looked to have crystallized stiff sap. After a short time it started turning black. The pics below show it better than I can describe it.
