I have grown moonflower (ipomoea alba) for several years with great results. But this year I am battling ants that cover the buds causing them to drop off, never opening. I finally bought some soapy organic spray and that seems to work, but now, although the buds fully develop, they only open three quarters of the way. Is it the spray? I have never used it before and can't imagine what else could be causing this.
Moonflowers don't fully open
