    I moved a rose back in October, kept it duly watered and it has survived :phew:

    However, it is not looking at all healthy :frown: the leaves are turning black and yellow. Is there something I can do? Is it lacking in something, if so, what?

    Thank you.

        :think3: Not quite ... I'll put some pix up later, but I've got to get a wiggle on now to get to work.
        Your spots look more closely packed than mine.

          Sounds like rose black spot:Rose black spot/RHS Gardening

          To be honest I find that RHS link unduly gloomy. I do get it, but only a little, only on certain roses, and mostly at this time of year - it is a fungus so encouraged by damp autumn weather. I noticed my lowgrowing Fairy rose in particular has it quite badly - so plan to pick the leaves off this afternoon and throw them away, rather than composting them. Earlier in the season I would also spray if need be, with a little Roseclear.

            Agree with Clare, pick off and clear leaves, as well as those that have fallen on the soil. Give the plant a thick mulch but most roses give way to black spot/rust at this time of year, it's making sure it doesn't overwinter below the plant that matters. A half milk, half water spray is supposed to work wonders for fungal problems like this.

              Not sure if you can still get it but sulphur spray is good for rose black spot.

                  Erm ... that would fall into the "no" category :whistle: My primary aim was to keep it well watered. But, I shall follow your advice and give it a Santa Chop :thumbsup:

                    the last thing your roses is water in october' the ground should be damp but not wet. you defanatly black spot ' not much of a problem pick off all affected leaves .check that the spots are not on the stem or branches .if not clear all the debery around the plant , if the black spot has reached the stem or woodwork then spray with fungus fighter ,by te way burn all the leaves you have removed. with bush roses I like to cut them down to about 4 inches from the ground either now or early spring, they realy take off next year and the flowers are biger and nicer,

                      I missed an important point but mark56 reminded me remember a well fed plant will fight off most things itself so put some manure around the plant, you can get puffer packs of green or yellow sulphur but it will not help your rose, I use it for mould that some times forms on pots,
