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.

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.
