    Hi

    I bought a beautiful standard Rose at the beginning of this season which was doing very well and producing magnificent blooms of white flowers but all the heads have gone now and the leaves are going speckled brown and dropping off, can you advise me what I am doing wrong please.

    Hi Trish, you're not doing anything wrong, believe me.:dunno: Your Rose is suffering from a bad case of Black Spot and Rust fungus which happens to a lot of Roses including mine.:wallbanging: :doh: You can use a anti Black Spot/Rust spray to prevent further spread but on of the other things to do is to collect the badly affected leaves off the ground and bin them, while also giving your Rose a high potash feed. Since, you've only got the plant this year it probably hasn't settled in and is still recovering from being in a pot at a Nursery.
    Is the Rose in a pot or have you planted it into the ground?:scratch: Roses are hungry plants and even more so if in a pot and need a weekly feed usually up to the end of August but, even now that it's September, I would in this case give it a weekly high Potash feed up to the middle of October. A little addition of Blood/Fish/Bonemeal to the pot or soil would also help. The Rose will recover but a habit of feeding your Roses weekly with Tomato Feed when they start to grow in early Spring next year will help.
    Can you tell me the name of your Rose?

      Good morning @weedaway my friend yes its black spot,You are indeed doing nothing wrong,this link should help you:smile:,but you must remove all affected leaves and dispose of them but not on the compost heap as the spores will be on the leaves,and any that have fallen off on the ground also remove and dispose of,and whats really important is never water your Rose from the top which would wet the leaves .always water round the base of your Rose,:smile:

        Cough! well, I didn't know there was so much to keeping roses,

        @ARMANDII The rose is in a pot the size of a builders bucket, I have put plenty of fish bone down and will get some tomato feed, I will look for the name of the rose and post it as I am finished for the day in the garden.

        @wiseowl I will dispose of the leaves as mentioned, I will follow all recommendations you both made.

        many thanks to both

          Hi Weedaway, well, if the Rose is not a dwarf Rose then I doubt if it will ever be happy in a Builders Bucket as it will be too restricted regarding root growth so essential to it's health and flowering.:dunno:

          Well, actually, there's not!!:heehee: Roses are like Humans in that if you have the right conditions, Home, feed it when it's hungry, it will be healthy and give you lots of flowers and pleasure but if you stick us in a Bucket we won't be happy:doh: So, if it's not a Dwarf Rose I would plant it in the garden as soon as you can and give it a high Potash Feed (Tomato Feed) until the middle of October. Like most plants Roses will last you years if you observe the basic rules, water, feed, give it a nice place to grow, prune it when needed......so nothing too complicated.:thumbsup:

            Morning'

            As promised, I attach a picture of the label with the name of the rose on, I did not remove the name of the supplier for any reason, hope that is politically correct.

              • Hi weedaway, thanks for the picture and No it's not a problem about the name of the Supplier as most of the suppliers are known to the GC members.:dunno:

              Rosa Iceberg ('Korbin')
              rose Iceberg (bush floribunda)

              [​IMG] [​IMG]

              This rose is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.

              • Position: full sun
              • Soil: prefers fertile, well-drained soil, but will tolerate clay and light soils too
              • Rate of growth: fast-growing
              • Flowering period: June to September
              • Hardiness: fully hardy
              • Pruning: light pruning from late winter to early spring

                Justifiably popular, ‘Iceberg’ goes on flowering right through the summer. Clusters of pink buds open to double, slightly fragrant white flowers, 7cm across. It is disease-resistant and easy to grow. There is also a climbing variety.

              So, as the advice says, Rose "Iceberg?Korbin" is a popular Rose although known more as "Iceberg" to gardeners than the name "Korbin"

                I have taken all the leaves off and trimmed it back now,

                so that's it for this year for the roses then?

                Hi Weedaway, well, perhaps for that particular Rose but I hope you can find space for in the garden somewhere as it will give you much more flowers and pleasure if it's happy where it is growing. But, for other Roses, they can keep flowering sometimes up to December!!:dunno::hapydancsmil:
