Queen Elizabeth Rose Hedge

I have a Queen Elizabeth rose hedge comprising 22 rose bushes hedge is now 5ft high. It has bloomed all summer but is blighted with black spot even though I have sprayed the hedge 4 times since April.  Apparently if you clear the ground when all the leaves have dropped off and dilute Jeyes fluid in a watering can and give the ground a good soaking this may prevent black spot reoccurring. Has any one heard of this as a possible solution?

    @Marlorena may be able to advise perhaps?

    Black spot is normal this time of year on old leaves, just snip them all off... I'm sorry I can't recommend anyone using Jeyes Fluid on their soil... diseases are prevalent every year with roses... one has to accept it to a certain degree...

    ...I'll tell you what I do... I hose off all the rubbishy leaves and leave them where they are... because it will come back next year and the year after that whatever you do..

    best of luck with your roses... lovely hedge you must have when in full bloom...
  • The hedge has been spectacular this year unfortunately so has the black spot. I had the tip ref Jeyes from a local nursery. Might give it a go but don't want to kill the roses that is what I worry about.

    ...I would never use such things but from what I gather it's illegal to use it as a soil sterilant... there are better ways to manage a garden I think... do consider whether this is the route you wish to go down..

    I wouldn't use Jeyes Fluid on the soil ( I have used it to wash the greenhouse floor and for the bins - no doubt it isn't a good thing but I love the smell!). Black spot is awful but getting rid of every leaf and spraying with good quality fungicide helps but rarely cures. You have a hard task due to the amount of rose you have to deal with. When the Rose's are dormant, I would aim to get rid of all the dead leaves and then try to minimise the infection next year by spraying all of the trees including the stems, and the ground underneath the. Then enjoy the blooms and try to live with it. You can always console yourself by knowing that you live where there is little atmospheric pollution. When there were lots of coal fires it was far less common because the polluted air kept it more under control.

    Jeyes fluid is also a deadly poison to cats and other mammals ... for some reason cats like to drink it when it collects in pools and puddles ... it causes the most agonising death. 

    Jeyes also kills all the important bacteria and invertebrates that make our soil the amazing living  fertile stuff that it is.  It should never be put on the soil ... and has  been said it is illegal for gardeners to use it as a soil sterilant.

    It's best to just accept that things like black spot are going to occur in your garden to greater or lesser degrees regardless of what you do - it's just part of growing plants. It doesn't do long term harm.

    We seriously need to stop using chemicals and sprays in the garden - especially when it's completely unnecessary.




  • Take on board all that is said, will give soil a thorough going over and  hope that the black spot will not be as bad as this year. Thanks for all your comments.

    Severe and repeated episodes of black spot will weaken your roses. Try Sulphur-rose, it can really help, and as far as I am aware, does no harm.

    A bit more information from the RHS which may help
