    Hello,
    I have two newly planted Double Knock Out Rose bushes, and have been noticing some of the leaves are being chewed on. Due to how expensive rose sprays are, I am looking for a few safe homemade spray ideas to kill these pests.If any of you are using a homemade spray on your roses that works, I'd love to get the recipe for it, and directions on how to use it.

    Thanks!

    Go to the Dollar store and get Sargeants cat flea spray !! Mix about 1 TBSP or a little more to a pint of water ! Spray your roses with it as needed !! The active ingredient pyrethrin, is approved for organics and is made from chrysanthemums ! Safe to use with no problems !! Just use as needed ! Heavy infestations can be made a bit stronger if needed ! Might cost about $3.00 but takes so little that it goes a long way !

    Hello Sjoerd,
    I also posted about this on another forum, and someone else thought the same, but I have not hit them with anything. I certainly do not know much at all about flowers, but have seen various other types of damaged leaves that looked similar to this. Looking closely, it looks like some type of worm chewed on the leaf. Notice how it's not a straight cut, but a curvy one? This looks typical of some type of worm damage, at least from my experience. If interested, here is the link to my post on that other forum. I also posted a little more info there. https://davesgarden.com/community/forums/t/1505791/

    Thank you very much for reading.

    The first and third pic will not hurt your roses,,they are likely eating the aphids or what ever the white insects are ! Instead of the mixture I posted above just use a hand spray bottle with a squirt of dish soap added and soak the bushes well let sit for an hour or two and see if the white insects are gone/dead ! Repeat if needed and rinse ! That will leave the good insects alive !

    I've read that about the dish soap and may have to give that a try. I'm not seeing a lot of bugs, but do see a few leaves that have been chewed on.

    Thank you very much.

    Hello Jeffery.
    I did have a look on "Dave's Garden" forum. More piccies to see. I saw some insects as well as damaged and dying leaves. I am convinced that the piccy above on this thread is from some sort of tearing type of trauma. The chewing holes and eaten places on leaves done by insects/caterpillars have almost always smooth edges, in contrast with the jagged tear above. The fact that the wound edges are brown indicate that the damage was inflicted some time ago.
    I shall watch this space in hops that you can get a definitive answer.

    Thanks again, Sjoerd.

    Just wanted to provide an update on my roses. Been seeing a hint of red peeking through the last few days or so, and when I looked out there this morning, I was surprised to see 3 roses on display on one of my bushes! As you can imagine, I am very excited about that! :D

    The plant and its flowers look smashing. Hopefully your rose has grown through the leaf trauma.
    Yeah...it is looking really good, mate.

    Thanks for the update, Jeffery. I did klik the link and read yours and everyone's comments. I wish that I could have something meaningful to say about rose choices for this location, but sadly I do not. Quite a few years ago I did an great deal of research (even went over to Britain to visit a famous rose-grower's business) for a rose for our lottie. I decided upon a couple and stuck with one of them and gave the other away. My rose was one for a sunny location. It is still alive and blooming like mad at the moment.

    You know, planting things under trees is not always successful because the surface-feeding roots of the tree takes away so much nutrition. Bulbs do oké under trees (in the ground). The idea to have your plant(s) of choice in containers is a good one, but just be aware that there are strings attached to this, like keeping a close eye on them in terms of water and food. Also research is necessary to develop a short list of suitable plants that will do well is shade or dappled shade. If you go the container route do not forget to put some sort of shallow receptacle underneath the container to hold water and prevent the roots from trying to establish in the soil under the container.

    I wonder what your final choice(s) will be.

    Hello again, Sjoerd,
    I truly appreciate you taking the time to provide me with such helpful information. I did end up planting the roses in the ground around that live oak tree back on May 4, and they seem to be doing very well, at least so far. I even planted a pink Double Knock Out Rose yesterday between the first two.Those are the roses I've been providing updates on. I apologize if my other threads were confusing to anyone. :D

    Again, thank you very much for all your help, my friend.

    Jeffrey
