That looks a lot like leaf scorch to me. Not a disease but the result of the leaves not being able to transpire moisture due to lack of soil moisture or too much soil moisture.

Here is a link that might be useful: About Leaf scorch

That damage is from last year. Indicates a chronic water shortage last year.

Winter damage is the probable cause. It always helps if you give some sort of indicator of your zone or location. Basically it is a transpirational issue, but very common in temperate zones and some people use anti-dessicants to try to avoid it. I've not found them particularly helpful and it's why in places like the mid-west holly is often planted with the same regimen broad-leaf evergreens like rhodies carry.......protect from winds, avoid southern exposures.
