I am a beginner in terms of gardening but enjoy it immensely and am new to this forum so grateful for any help and advice.

I love roses and have planted three or four types in my garden. The white roses often end up with black spots on the leaves.

I also have some beautiful red roses which have just started blooming, but they have white spots on them and look pretty awful. 

I have no idea what us causing the problems or how to treat them so any advice would be most grateful. 

I've attached a couple of photos.








  • Hello, Bev.....welcome to the forum.

    The 'white spots' you speak of, is mildew. A fungal disease  that  is very common in roses I'm afraid.

    Treatment? You'll need to spray with something like 'Rose Clear'.

    The reasons your rose blooms may look a tad sad, is because of rain's always like this with big blousy blooms so it's a good idea to gently shake the water out of them after rain.

    Hi Dave,

    Thank you so much for the welcome and advice.

    I will make sure I get the spray today. 

    A lot of my friends have memories of gardening with their parents / grandparents, but unfortunately I wasn't fortunate enough to have that experience. My 10 year old daughter loves helping me out in the garden so we are on this wonderful journey together.

    Again, many thanks for your advice.

  • "A lot of my friends have memories of gardening with their parents / grandparents, but unfortunately I wasn't fortunate enough to have that experience."

    Yes, this is often the way of it.....gardening with parents/grandparents I mean.

    "My 10 year old daughter loves helping me out in the garden so we are on this wonderful journey together."

    What a wonderful journey this will be for you both and credit to you for encouraging her.....but I would urge you both not to get too downhearted when things don't go well.

    Remember, they are a lot of people here with lots of knowledge who are always prepared to help.

    Good luck. image

  • PS. The black spots on your roses is a fungal disease too, called (surprise surprise) 'Rose Black Spot'.

    I would suggest you remove the affect leaves and burn them and don't allow a build-up of affected leaves around the encourages the spoors to spread.

    Interestingly, rose black spot has become more widespread since the air has become cleaner. In the old days when most people had coal fires, it was rare......this is because the sulphur in the air killed those spoors.

    Hi Bev I' m a huge rose fan too,and my little girl of 3 is my best little helper, I'm a pretty new gardener so haven't anything to add apart from have you fed your Roses? You'll find loads of friendly advice here

  • Bev, I'm not sure I've given you the right advice.

    Since I replied to your query, I have enlarged you pics and have to say that the foliage seems to be healthy, which would rule out mildew.

    The only damage I can see to the flowers seems to be weather would appreciate other's opinions.

    Hi David,

    This gardening lark i certainly a learning curve for me, but I do love coming home from work on a summers evening, to relax in the garden. I'm pretty squeamish to my daughter is thankfully on hand to deal with slugs and snails; I LOVE Hostas and have quite a few which have been doing pretty well this year.

    Your advice has been helpful in that I know what to look for in terms of identifying fungal infections.

    Hi rosemummy,

    Do you know I haven't fed them - what do you use? I'll take a look in a local nursery to see what they have.

    I think my reliance on my hubby and his so-called knowledge will cease as I will be referring to this forum instead!

    I can't help myself - every time I go out, I'm picking something up. I have pink campion, hosts, roses, lilies, bearded iris, foxgloves.. the list is endless. I'm out of work at the moment so making the most of watering the garden daily. I tidied up the front of my house and planted fragrant flowers which have been smelled and notice by visitors as they come in.

    The garden is bee friendly garden and now our four year old German Shepherd has grown out of trampling all over everything, the garden is starting to resemble something nice to look at image

    I use a rose feed from David Austin and as with everything else, they get tomato feed when in flower, I have just bought a general feed for all other plants as I haven' t fed much before, as I say, I' m pretty new to gardening too, always been interested but moving house and having our own garden rather than a 2 square meter bit of grass open to shared backyard made me a woman obsessed!

  • BusyBBusyB Posts: 87

    Great, thanks for the feed advice. I will definitely go and get some.

    I know what you mean about moving house etc. But between that and silly hours spent away from home in the office got in the way of me being able to do anything. 

    Our garden is quite big (approx. 100x50ft). The main problem we have with it is that the entire right hand side is forever shrouded in shade thanks to our neighbours cobnut and out of control Ash tree (that the tree surgeon estimates is about 60 years old and has never been pruned). I had it pruned back a bit last year as it was hanging over the rear of our garden and into the neighbours the other side of us. It's still quite shady, so I'm now looking for plants happy in shade. We have a wonderful nursery near us (not one of the well known chains) so I'll go take a look image
