Today I noticed on my roses out the backyard that most of the bud sites are
covered in aphids. Now before i go on I should warn you that i put the "um"
in greenthumb and ive never tackled aphids before.

They all seem huddled up together in groups on the bud sites - i can't
really see any on the stems or anywhere else as such, so it seems like I
could get rid of most of them just by chopping off all the bud sites. I did
notice a few Ladybugs which is cool, but there's only a few of them and
perhaps thousands of aphids so the Ladybugs cant do it alone

So I want to kill the aphids but not the Ladybugs, anyone know any tricks?
other than breeding Ladybugs :P
Thanks
