Dahlias

Question

I have a dahlia in my garden and I noticed a couple of stems have tiny black creatures on part of the stem.how do I get rid of them?

Answer 1

Tiny black creatures sound like aphids. You probably don't want to blast them with the hose; the force might break a stem. Insecticidal soap or neem oil should work well. If you don't think they are aphids, please write again with detailed description and exactly where they are on the plant. A picture works wonders.
