Default 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.

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.

Japanese Beetles are tough to get rid of, one thing to use is BAYER
Advanced Bug and insect killer, see that here;

Most climbers bloom on old wood and pruning is not recommended or at
least should be done on three year old canes so the two year old canes
can bloom for you. Remember, this years growth will be next years
bloom. We will need your plants' name to give exact bloom plans.

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?

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.

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.

Hi. Just joined this forum, so you may have found a solution already to your problem. I'm in the west of England and had the same problem with Japanese beetles last summer (also called Garden Chafers here). There is a new product, a nematode, which you water into the ground surrounding the rose/s in September. The nematode attacks the beetle lavae, so they don't hatch next year. I buy these on the net from a uk website, but, of course, they can't be exported to US as they're live! See if you can find them on a US website. Good luck! diana
