When was the last time you wished you had ‘secret’ brush piles to fish? It happens to me all the time.
Start planning a Christmas tree recycling program in your neighborhood. Provide a drop off point for their trees and you’ll have all the brush pile material you need.
Many landscape companies have cement block seconds that you can get cheap. Use nylon rope (it rots very slowly) to attach the blocks to the trees (1 or 2 trees per block) and dump them where you want them.
Tip—Lots of trees piles together are more effective than a few here and there.
