Hi! I planted a Echinacea PowWow Wild Berry plant on May 30, 2016. I mixed Miracle Grow flower and garden soil with the existing soil which also contained some manure from last year. The plant faces East which gets morning and early afternoon sun, and filtered late afternoon sun. This plant has not grown at all. It is only about 4 inches tall. I have a Solar Flare next to it that was planted last year that is about 15 inches tall. Do you have any idea what I would need to do to get it growing, or does it need more time to get established? Thank you! Karin
