Hi! I have 3 questions, please help!!
1- My holly bush is getting yellowing leaves with dark brown parts (kind of looks like a cow print).
2- Indian Hawthorne bushes are getting yellowing leaves with black spots (the spots are pretty symmetrical and crispy/dry).
3- The confedrate jasmime vine looks like its dying- turning brown/tan one section of vines at a time. (Can dog urine hurt this plant?).
Any help would be appreciated:)

It's really difficult to diagnose plant disease problems without actually seeing the plant so I'm going to suggest you place some of the affected leaves in a plastic bag and seal it, then take it to your nursery, Cooperative Extension office or Master Garden Clinic for positive identification of the problem. Your holly and hawthorn could have fungal or bacterial leaf spot. If you remove the affected leaves you'll keep the disease from spreading and you may avoid future development by pruning your plants to increase air circulation and sunlight penetration. As for the jasmine, dog urine can definitely affect it. Try a temporary fence to discourage dogs from urinating on the plant. I think you'll see improvement!
