We have tons of tiny little black bugs on our magnolia tree, and they are spreading to other trees. Help!

I suspect you are seeing hordes of aphids on your magnolia tree. These are easy to control with applications of insecticidal soap, but not so easy to control if your trees are tall and the insects are not accessible. If you cannot easily reach the clusters of aphids so you can spray insecticidal soap, you might be able to hose them off with a strong stream of water from the hose. Water will knock them off the plant; insecticidal soap will kill them. Hope you can easily get them under control!
