I need HEEEEEEEEEEELLLP!!! Pine needles are not popular in this area. I've never installed them v/s mulch. The bales of needles I have saw appear to be 3 cu ft bales or about 1x1x3. I didn't drag out the ruler or anything to get technical with it, just approximate. They don't appear to be tightly packed bales or anything. So looking at it from a mulch coverage perspective.... it looks like one bale will cover 9 maybe 10 Sq Ft 4" thick. At $3.50 - $4.00 a bale it seems like the material would get awfully expensive awfully quick. I mean am I missing something here??? Am I highly underestimating the coverage area per bale? Or is the initial cost recouped in the long run because pine needles require less repeat applications? I'm lost never having done pine needles before. In addition to the material cost per bale, what is the average install rate a bale???
