Answer: Topsoil and compost above ground level won't change the drainage problem where the roots of your juniper are living. It would be better to dig the plant, amend the soil with the compost and topsoil and replant your juniper. The yellow green color indicates root stress. Overly wet soils can lead to root rot. You may be able to save the plant by digging it up and amending the soil. If you do not, the juniper can die. Let's hope you caught it in time!
