Planting Evergreen Trees in Landscape
I am planning on building berms in my yard from topsoil. I want to plant evergreen trees in these berms. Can I use Alpaca manure that has 'cooked' for a year (in some cases longer) or so to build the berms and thus be the base soil for the evergreen trees? Or should I mix this Alpaca manure with topsoil? Is the Alpaca manure too strong for the evergreen trees?

I wouldn't use straight Alpaca manure, even if it is well aged. A 1:4 mixture of manure to soil is probably all you'll need. Here is more information on using alpaca manure in the garden: https://www.gardeningknowhow.com/composting/manures/alpaca-manure-fertilizer.htm
