What Could Be Causing My Jasmine Leaves To Turn Red?

Question

I have had two star jasmine plants for the last three years. For the first year they grew great, but in their second year all the foliage turned red and they dropped a lot of leaves. Since then they have barely grown and ALL leaves have been red. It does not matter what time of the year it is. They are always red and leaves are pretty sparse. I do not water them fall through spring, as we get 40+ inches of rain at that time and nothing ever dries out. In summer I water them about once a month. We do not get summer rain hear, but I am in a cool foggy coastal climate. I have seen jasmine around town that looks lush and healthy. I have tried fertilizing with no effect. Any suggestions for be appreciated!

Unfortunately, your photos did not come through. I am unable to see the issue in question.

Typically, this is a pH issue. It can be a phosphorus deficiency, as well, but it is best to test the pH first to rule that out. If soil tests confirm that nothing if wrong, or everything is in balance, then it will likely be disease.
