    Anyone know what's wrong with these Rosemary plants? The leaves are turning redish brown and eventually drop off or die

    The first two is a new plant i got recently the third is a cutting(the only one that survived the winter!) from an established plant that died last year with smiler problems.

    Check the growing tips..are the leaves bunched in together and coated in white dust?
    Chances are its a caterpiller in there causing the problem..i would remove the affected tip anyway.

    Phosphorous deficiency!

    The
    leaves that turn purplish in color
    would suggest the above.

    The would suggest the above.

    I don't know the first one i potted on into a bigger pot as soon as i got it, with fresh compost and it has been fed. The one in the third picture could be Phosphorous deficient it does need to be potted on and hasn't been fed but i think they both have the same problem.
    I will try feeding them both and see what happens.

    Those weed growers put allot of effort in!
