Help My gourds are infested with aphids
I have a few different species of gourds. My first year trying to really grow some. A week or so ago I noticed this orange looking bumps that were stickey under side of leafs. Then over night semmingly they had a lot of black areas ,, even on the wood 1x2s I used to build the fence around garden. I sprayed with Dawn , as a fellow recommended at Lowes, may have killed some bugs, but still living. I sprayed with a general insecticide yesterday, and looking at my plants this morn,,, I have most leaves and plants looking like they are dying . Leaves are brown spotted or black.
Is it too late? Should I cut the worst leaves off , and hope the gourds will try to mayke it thru?
any advice greatly appreciated. I am a complete novice, I would hate to lose the whole garden.
