Douglas fir needles and cones
Hi there, I recently moved into a home that has about a dozen Douglas Fir trees, very old. The previous homeowners used the space under the trees as a bit of a dump and apparently never removed the cones and needles that fell from the trees. We would like to clean it out. I would also like to get rid of some of the lawn in the front yard by creating a berm that I can plant with things like Lavender, possibly blueberries, rosemary, and other useful, lower maintenance (as opposed to grass) plants. I’m writing to see A; will it hurt the Douglas Firs if we remove the old needles and cones from beneath them (since in a forest this material would just stay where it falls and perhaps provide some insulation?) and B: I was wondering if mixing the needles and cones with soil would be alright as filler for the berm I’d like to create. Obviously I would add soil and hopefully some rock to make up the berm. And a final question; is there a local resource to get rocks economically other than buying them from a landscaping company? The house is from 1947 and needs quite a bit of updating, so our budget is rather small. Many thanks in advance for your help.
