my rose don't bloom, and japanese beetles are eating my roses
I am looking for some help with my roses. Some of them don't bloom. I
did cut them down to one foot in fall, is that a mistake? I have some for year and two. Also, Japanese beetles are eating leaves and flower buds even before they get to open. I sprayed it with Bug and gone two weeks ago, but they are back. Any idea if I can spray again? How many times I can spray them without damaging the plants? I am in Chicago, IL. Thanks for any information. |

Hi Maria,
I have a yellow climbing rose that I cannot get to bloom either. Cutting your roses back in fall is great, it will actually help the plant as it will produce more new and healthy shoots in the spring. If your roses are not cut back they are also more prone to wind damage. From what I have read there are some roses that are genetically "bad" and will not flower... As far as the Japanese beetles are concerned - they are pretty bad from June - August. I think you should be able to spray again since two weeks have already passed. I would not spray more than once/week or it may damage the roses. I like some of the tips that http://www.easyplantcare.com/ recommends for taking care of the Japanese beetles, maybe you can try some of these alternatives for the time in between sprayings. maria wrote: I am looking for some help with my roses.

I have some Cutting that much seems a bit to much, generally cutting 1/3 off the top is recommended. If your bush is three feet tall cutting off one foot would be about right. What are the names of your roses? Also, some roses bloom on old wood, you may have cut the bloom wood off. for year and two.

Japanese Beetles are tough to get rid of, one thing to use is BAYER Advanced Bug and insect killer, see that here; http://www.bayeradvanced.com/lawn/pr...d=49&source=ga Keep us posted Joe T Baytown Tx. |

Kill the beatles, crack 'em in two with your rose prunners. The first beatles are scouts for the others. What kind of spray do you use? maria wrote: : I am looking for some help with my roses.

http://www.uky.edu/Ag/Entomology/ent...rees/ef409.htm Univ of Kentucky has a good page on jap beetles. Very complete. Says to collect beetles because they emit phernomes that attract others. Traps only attract more beetles, and sprays have limited effect. They migrate during hot days with light wind. |

Traps only attract more beetles, and sprays have limited effect. They migrate during hot days with light wind. The other thing is that while they're eating, they're also breeding (if you look close, you can often see this in action!). This means that they are dropping eggs into your soil, which next year will turn into grubs, thereby ensuring a constant supply (they don't even have to migrate in). So you have to take a two-pronged approach - next spring, you need to use a grub killer (milky spore or one of the commercial grub killers). The timing is important, IIRC. I think you have to apply it as the grubs work their way close to the surface, around May or so. This will reduce the infestation. Then, one thing that you can try is misting the top of each bush with a NEEM oil spray. They don't like the smell. You should do this early in the morning so that the oil doesn't burn the leaves in the hot sun (think of what Hawaiian Tropic does to your skin in the mid-summer afternoon). You can do this two or three times a week without harm (plus is deters other beasties as well. Some folks in my region swear by this, and it makes sense, since JBs are scent driven. The easiest and most environmentally-friendly way, but most time intensive, is to simply knock them off into a cup of soapy water. Getting rid of the grubs next year is the best way to keep your infestation under a semblance of control. Sure, they can still fly in. But you will eliminate a BIG source of insects, an infestation that will bring in even MORE of the little irridescent creatures. |
