I have multiple jasmine vines which I planted this early summer. I noticed the vines have been thriving; however, just today noticed orange colored leavers on the jasmine vines. It generally looks like it might be on all the 15 vines I have. We have an irrigation system, but due to the high temperatures as of late, have been giving them extra water on the days they are not receiving irrigation. Could this be the cause of the changing color? Also noted some little tiny black spots on the leaves which have changed. Is this rust or is it to much watering? Should I pluck the leaves?
You may have a nutrient deficiency.
The article below will give you a good coarse of treatment.
You may also want to use Neem Oil on the plant, this can protect against both insects and fungus as the plant is stressed.

What is that nasty sticky, gummy blood substance that oozes so freely from the vine. And what is best used to wash it off my person? - EWW! As much as I have enjoyed the fragrance of jasmine blossoms, the shared front hedge and two bushes on my mom's property have had too many years of lack of attention. It seems almost as if they were to be let alone they would have this whole neighborhood "wrapped" up tight. One day I might find a person that walks on the sidewalk all wound up like a treat in a spider's web. What can be done to get them back in order w/o completely removing and starting over? Again - EWW - with the sap!
Your Jasmine likely has a Scale infestation.
Honeydew is formed by the insects feeding.
You can treat with Neem Oil. You will likely need to treat weekly until the infestation is controlled.
Here are some links for you.

This stuff has already killed my jasmine plant and now is starting on my gardenia and hibiscus. I can't tell if it's mealworms or white mold.
This could be Mealybugs, fungus, Powdery Mildew or a few other issues.
Treat the plants with Neem Oil.
This works as both an insecticide and fungicide.
I have a listed a few links for you with more information.

My jasmine is looking wilted and the leaves have all gone a lot darker. Could you help me please? The plant is in a clay pot and tied to a pergola. It has been ok and flowering for over a year.
It may have become root bound and is lacking both moisture and nutrition.
Also check for insects or a fungus issue. If you suspect this, treat the plant with Neem Oil.

We have a metal fence around our yard that is covered with jasmine vines. We need to have the fence painted. If we prune the vines back to the base to allow for painting, will they grow back? The vines have been in place about 10 years and are pruned every year but always cover the fence, even after pruning.
You can prune the Jasmine to 2 feet from the soil surface.
As the vine grows back clip all but the strongest stems and attach these to the fence support.

What time of year is the right time to move winter jasmine?
The best time to move a Winter Jasmine from a pot to the ground is in the fall.
Transplanting existing Winter Jasmine also should be done in the fall, but only after it is done blooming.
