Unhealthy rosemary

One of my rosemary's started going black earlier on in the summer, i thought maybe it had been scorched when watering, but now not so sure.

Any ideas what may be wrong with it ?  Will I be better off just taking it out ?

    I rarely water my Rosemary, they like to be quite dry.

    Oh I wasn't watering them, I was being lazy and trying to fill up the bird's water so spraying over the top of them...image

    Could it be Rosemary Beetle , mine was full of them this year and ended up looking like this. 

  • Mine looks a like this, doesn't seem to have any beetles but has been attacked by leaf hoppers

    Rosemary is not usually long-lived . I'd just get another and watch out for the beetles. Squash them on sight!

    There are different varieties of Rosemary, some not very hardy. Mine is hardy and I've had it for years. It got very big after about 15 years, I took several cuttings a few years ago and replanted them, now it's big again. It hates too much wet if we have a wet cold winter, recovers though.

    Rosemary beetle eats the leaves, doesn't make them change colour and they only eat them in late summer when they lay their eggs, then the grubs eat them and so do the beetles during winter. But the beetles don't eat during the summer.
