Hi Kelly, I'm in VA, too.
Where are you?
I've got aphids on my roses. I made a spray from the leaves of rhubarb; I don't think it worked 100%, but it's part of my arsenal. I've got some serrano peppers I'll be making a spray with next. I've never heard of draping banana peels ON the plant. (I do have 1/2 a peel buried under mine) Do they not rot the stems, or do they dry out quickly?
I've got a ton of wee little buds that the aphids and I are battling over, I smush them with my fingers every time I go by the roses, and sometimes I spray in the evenings. My mom's rose bush hasn't produced well in about 2 yrs. We finally got a bud to bloom on hers the other day (yay!), but we're willing to drape banana peels all over the place if it will win the war!
