I am trying to create some new flower beds and am having trouble getting rid of the moss.  I have built up the ground and incorporated some potting soil and some top soil as the ground is not the very best.  The moss came back this year.  Any help you can give me will be greatly appreciated as I would like to do the beds right the first time.  Yes, I do have a lot of pine trees and some of the beds will be around them.  I am also trying to do beds around the house and this is where I also have the moss problem.

In my experience, moss is often the sign of several factors, Acid Soil, Compaction, Shade, & Wetness. You mentioned Pines in your post which often cause acidic soil conditions due to needle drop. Acid Soil: Take a soil test and follow any lime requirements for your desired plants. A pH of 6.5-7.0 is good for "Most" plants. Compaction: Make sure area isn't hard and compact. Poor soil structure reduces pore space in soil and causes problems. Till aerate or incorporate amendments into soil if needed. Shade & Wetness: Moss tends to grow well in shade. Maybe this is because these areas stay more damp, I'm not sure. I would try to increase light if it is lacking and control soil moisture. These cultural practices is where I would start before going to a chemical solution. Several Copper based products are out there but if the underlying cultural problem isn't addressed you are just putting a band-aid on the problem.
