BTW Ladybugs are a rose growers bestest defence agains our worst nemisis
APHIDS. Aphids not only litterally suck the life from your roses, they also
spread diseases ( Viruses and sooty mold mostly).

Best of luck,

I have David Austin Roses in my garden and mixed it with Delphiniums and
Irises in the same bed. I would like to compaign plant with certain
plants
to prevent diseases on my roses. I have noticed lots of spiders and lady
bugs and I am a person who doesn't like to use pesticide. Any suggestion.

Sorry about the spelling.

Regards.
