They get full sun.I water them appropriately. It doesn’t look like anything is eating them. The leaves are turning yellow and it’s not making much foliage. Any ideas of how I can stop this What’s going on?

    Before the leaves turn yellow, do they get black spots (or brown spots) on them? What is the soil like? I have had Knockout roses die in heavy clay soil and the yellow leaves are typical of blackspot, a fungus.

      Jeanne, thank you for replying. I did not see any obvious signs of disease but will pay closer attention. No clay soil. I do have three other knockout rose bushes Next to the one with the problem. Two of them are fine and the one next to it looks like it’s leaves are also starting to turn yellow. I really appreciate your feedback. Thank you.

  • Leaves turning yellow is typically a sign of over watering. Have you fertilized at all yet this year?

    Well, with the heat in Louisiana this year, didn’t think that over watering could be the problem but, I don’t know anything about roses so it’s a possibility. These are over a year and a half old and had been flourishing .So, it took me by surprise. I have not fertilized this year or since I’ve planted. Didn’t think I needed to because they were doing so well. It seemed this one started all of a sudden. The others near it are still doing well except the one next to it. It looks like it’s about to follow suit. I think I’ll do what you said and try to fertilize. I so appreciate your taking the time to answer and advice. Crossing my fingers. Much thanks.

    I have several rose bushes. When we get heavy rain I will begin to see yellow leaves. Also, if you over water them they will attract more bugs.


    i also make a habit of cutting the roses when they begin to die because they attract Beatles. If they get in there, they eat all of the leaves.


    when there is a lot of rain I put some diatomaceous earth on the entire plant. It is safe for your plant but they will look sad for a couple of days. lol. I don’t cake it on. It’s a powder and i just put it in an old powder bottle and squeeze it and put a cloud of smoke all over. It will blow off in a couple days or the rain will get it the next time.


    One final thought.... make sure you are feeding your roses. I had 3 rose ‘stumps that are coming back and I had thought they were gone. They were left from when I bought the house. Anyway, after feeding the other roses for a few years I was excited to see they had all came back this year. I use miracle grow shake for roses with little balls that you shake on the ground around the plants. I used to buy this really inexpensive box of plant fertilizer in a box from Walmart. I used to mix it on my soil in like April or even March where I used to live and I heard the rose bush had never bloomed in all the years the neighbor had lived there and the older lady across the street whispered to me - what’s the secret to your flowers always being so beautiful. I don’t think anyone believed me when I told them I used a 99 cent box of Walmart fertilizer lol. I would still use it but I had broken my leg and my husband thinks you always need to spend a lot of money and he bought the miracle grow. Use it as directed because it can hurt your plants too. Anyway, Now you know everything that I do.


    I will I’ll show you a couple of photos of a few of mine. The white with the pink around the edges were thought to be dead. The peach ones are 3 years old. I bought them. I wish that I could easily find you a photo of all of mine on the fence line.

      Hi Rob, I know exactly what you mean. They’re not clear on their instructions - at least the one I got just said to shake some on. I usually put about 2 Tablespoons of the miracle grow shake and I spread it in about 10-12” circle. Idk if that helps.


      If I remember correctly it’s about a tablespoon and a half in a gallon of water of the liquid miracle grow.


      Like you, I was afraid of burning them up too. Another thought..... I’m sure you have them in a sunny area but I don’t think I mentioned it before.

    Maybe add some bark mulch to prevent rapid evaporation in a hot climate or sunny area. I would fertilize also.
