best treatment for magnolia scale NOW
hi guys, i think i have magnolia scale on one of my new magnolias. they are small sesame seed sized insects covering my magnolia branches and thick stems and they are black in color.
what is the best way to get rid of them now? i tried neem oil and it didn't seem to do anything to them. i've heard of horticultural oil. is that any different than neem oil? is there a better remedy to control them right now?
thanks in advance,
