Jade plant droopy and dying...help!

My lovely jade plant that used to be lush and full has been suffering for some time and now seems like it's taken a serious turn for the worse.
It had an issue with mealy bugs that I foolishly overlooked for too long, and began to get what looks like a fungal infection. I tried gently removing the mealy bugs several times, tried a diluted alcohol spray a couple times, as well as later trying a neem oil spray twice to see if it improved at all.
Now the stems are drooping and dropping shriveled, dry leaves and branches--faster every day, it seems.
Can this plant be saved? Any advice is much appreciated!! Thank you!

Giant Hogweed reporting and control

Hello, with some recent National reports of serious physical reactions to Giant Hogweed, I have taken notice of some specimens of that plant on my property. Does this need to be reported? If not, what do you recommend for eradication?

Tree Identification

Hello, We just finished a 4 day trip on the Deschutes River in Central Oregon. This tree was about 4 miles above Harpham Flat on river right. There were several and it was about 20 feet tall. I'm including an image of the leaves and bark. Should have paid more attention sorry but very curious. Thank You! Mike Rudolph

confirmed infestation - now what? for a home gardener.

Although I have sprayed for fruit rot this year most of my crop now has larva present. I even did a spray or two with Sevin and malathion at a couple of week intervals, with no apparent results. I recognize that this years crop is lost, but where do I go from here?

What should I do next year to eliminate another lost crop? Can you suggest a regiment that I follow next year? Or should I cut down the tree?

Thank You

Soil sampling

My plants are not growing well in the sandy loam burms we built, despite adding potting soil and a compost mix from local suppliers. How can I test my soil to see what is missing? Thank you.
