Look on the UNDERNEATH side of the leaves.
You'll have to look carefully, but there are, I bet, teeny little green "worms" which are called ROSE SLUGS.
They are the larvae of sawflies.

You can use an insecticide on them, but honestly, unless the infestation is massive, I find it easiest just to find 'em and pop 'em.

Hi,

I can almost promise this will cure any problems with your roses. I grow the most beautiful roses you have ever seen and I learned everything the hard way.

I tried everything when I first started my rose growing and what i learned that works and worked everytime and the best is(1) NEEM oil &(2) Rose Defense

The NEEM oil just about gets rid of everything that could happen to your plant. You will need to give it time. then every ten days or so use the Rose Defense (it is the name)

Buy NEEM oil. It comes in a white rectangular plastic bottle and It is called Neem oil. I mix in 32 oz. of water about two cap fulls (a cap from the small bottle) in the 32 oz. of water, then I add about a teaspoon of Ivory liquid. You will find that you can spray every day and spray the whole plant flower and all and underneath the leaves also. After about two weeks you will see a remarkable difference and you should beging to see lady bugs. This spray will discourage deer from chewing your leaves also.

As you begin to spray, start gently pulling off little by little each day or every two days a few leaves that infected. Make sure you do pull off any beginning red buds. You do not want to de-foliage your plant at once but you want to start removing a leaf here and there. Throw away the infected leaves. Hope that helps some. I have other tips for other things also. Both of those items are organic.

hey sonia rosa- is neem really that awesome? i have pure neem oil and was told it will keep PM at bay too.

ok, thanks everyone for the advice!

will check [underneath] the plant very carefully.

the plant does have quite a bit of new growth in process, and, has put out a couple of wonderful blooms---with a number of buds preparing to open!

If you are going to use Neem, use it VERY early in the morning, or at night.
It is HIGHLY toxic to bees.

Hi Jeri,

If you dilute the NEEM oil the way I do you can use it anytime. I do not recommend noonday in extreme heat but I use it all the time and I have a host of bees and lady bugs.
There is a lot is mis-informationa about NEEM oil. I have used it for 4 years now and use nothing else, other than Rose Defense.

Happy Growing,
Rosa

Hey Joe,

I am guessing you are talking about powdery mildew. I had bad mildew before I started using Neem Oil and no more problem. I do not suggest straight Neem Oil. You must dilute it.

Happy growing,
Rosa

*** Check the websites.
Ask a beekeeper (I did.)
Neem Oil is highly toxic to bees.

I'm not saying you can't use it. I'm saying it is toxic to bees, and is best used when they are not out working.

Jeri

hi jeri,

Every website i have looked at claims that Neem Oil has been shown to be non-toxic to people, animals, bees, etc.
It is a vegetable oil. It is not a cide. It is not used to kill anything it just repels like galic and creates a slick surface so nothing can attach. It has been used in cosmetics in the Far East for years. I would be interested in the websites that claim it is toxic to bees. As I said I have a ton of bees in my roses. I do not spray them, but I do spray the bushes.
Happy growing,
Rosa

Seems that a lot of people on here use Neems oil so yesterday I purchased some Neem Concentrate made by Green light for my sad looking roses. I'm a novice at keeping roses healthy and alive. As I have said in other posts I have killed many of them. But am determined to get it right.

I am confused by the bottle of Neems I purchased. It says it is for organic gardening. I thought organic meant safe for humans and pets. As I open the directions for use booklet the first thing listed is Hazards to humans and domestic animals. Harmful if absorbed through skin. Causes moderate eye irritations. etc....

Also it just says kills bugs and diseases. What kind of bugs? Just the bad ones or does it also kill the good ones?

My directions say 2 TBSP per gallon (128 ozs.). and to use every 7 to 10 days. To me that seems pretty watered down and with it being that watered down it still says to only use every 7 to 10 days.

Rosa I got to looking at your mixture of Neems oil. You are mixing 2 of the small cap fulls (my small cap looks to be about a tsp each so about 2 tsp) to 32 ozs of water (1/4 gallon) and 1 tsp of Ivory dish soap. and you are spraying this daily? The leaves aren't burning or shriveling up?

I've also read on this site that too much dish soap could cause burning to the leaves and 1 tsp in 32 ounces seems like a lot of dish soap to be spraying daily.

Rosa, Even though I'm a little skeptical about spraying your mixture daily. It can't do any more damage than the blackspot or sawflies have done. I think I'll put on a mask and rubber gloves to do the mixing and pray I don't kill any beneficial bugs.

I'll of course wait until all the bees have gone to bed before spraying.

Wish me luck and Rosa if this mixture works for me I'll be forever in you debt.

Sorry for Hijacking your thread Flybynyte.

Thanks
Andrea

some of the most toxic substances on earth are organic. cyanide for one. (Uranium for another)
pyrethrins, a popular pesticide is from a type of chrysanthemum.
Also, many people mistakenly think that anything they buy at the health food store is completely safe for them too, while it is not.
I will get off my soap box now.:-D

WOW! Lots of varying information here! I searched the web, and found lots of data, but this about sums up what I could find;

Neem oil is derived by pressing the seed kernels of the neem tree. It is very bitter with a garlic/sulfur smell. A single seed may contain up to 50 percent oil by weight. Neem oil is an excellent moisturizing oil and contains various compounds that have insecticidal and medicinal properties. It is used in making shampoos, toothpaste, soaps, cosmetics, mosquito repellants, creams and lotions, pet products like pet shampoo, etc. It also contains vitamin E, other essential amino acids and some percentages of fatty acids. Neem oil is used for treating many skin diseases viz. eczema, psoriasis, skin allergies, etc. and is being studied for making contraceptives in India. A compound found in Neem Oil and neem leaves extract- 'Salannin', has been proven to be safer but more effective insect repellant than DEET. Neem provides protection from not only mosquitoes, but also from biting flies, sand fleas and ticks.

Neem oil has been used for hundreds of years in controlling plant pests and diseases. Many researches have shown that the spray solution of neem oil helps to control common pests like white flies, aphids, scales, mealy bugs, spider mites, locusts, thrips, and Japanese beetles, etc. Neem oil also works as a fungicide and helps control powdery mildew. Some people have also experienced good results with neem oil spray on black spot. Orchid owners use pure neem oil spray to control pests like mealybugs, spidermites, etc. One of the main ingredients in neem seed oil is Azadirachtin that works as an insect growth regulator, thus preventing the larval stage to molt into an adult. As neem is very bitter in taste, it also works as an antifeedant thus making the leaves sprayed with it very distasteful for the bugs to eat, and the bugs choose to starve themselves than eat the leaves treated with neem. Neem oil is bio-degradable and has proven to be non-toxic to mammals, birds, bees or earthworms. It is biodegradable and breaks down easily and quickly. Neem has also proven to be not harmful to adult beneficial insects, since it primarily affects only plant sap-sucking insects, which feed upon the treated plants. However it is recommended that care should be taken not to spray neem oil solution when honey bees and the larvae of beneficials like ladybugs, etc. are present. Neem oil spray like any other oil spray can also burn leaves if sprayed in sun.
