I have rugosa roses. Obviously different from tea roses and other fussy
varieties, but the rugosas have had no diseases at all in the 10 years I've
been growing them. Their scent is terrific and even the leaves are
attractive. Yes, they have thorns, but I learned many years ago that if I
don't roll around on the bushes, I don't get hurt.

Lawn treatment is less effective if you can't get your neighbors to pitch in
and do theirs, too. And if you're using something other than biological
controls, you're poisoning your land for no good reason.
What others say about traps is only partially true. They come with very
clear instructions about placement (upwind, downwind - I don't recall at the
moment). A friend of mine eliminated her beetle problem pretty much
overnight a couple of weeks ago. Did the traps attract some that might not
have otherwise been there? Probably, and obviously, since it would be
illogical to wish they'd only attract the bugs from YOUR property. But the
traps DID distract the bugs and saved a bunch of plants.
The traps also offer a clue as to how long your vigilance must last. The
instructions clearly describe the seasonal nature of Japanese beetles.

The grubs eat the grass roots causing brown spots to appear. It would
certainly help the lawn if the product is applied in a timely manner.
The J.beetles will fly to your property to sample your roses. I use a
systemic applied to synchronize with the June emergence. It is very
effective. Another method is the catch the beetles manually with a
wide-mouth jar containing a 1/2" of soapy water. Hold the jar
underseath the insect, a small tap, and drowns in the solution.

Which systemic do you use?

I use Ortho Rose systemic/food. If I *could* I'd get a systemic
product without the (inorganic) food I would. I tried a Bayor
product but not quite as effective as the Ortho. It is a bit too late
in the season for using systemics, most destructive insects eggs have
already hatched.
