I've used "aged" coarse sawdust for years, it is actually shaper chips from an Amish pallet plant. Mostly Cottonwood, I haul in 3-4 16' trailer loads/year, to be used the next year. Been using them on this property for over 25 years with very good results. Use them on vegetable gardens, flower beds & pots, & on trees & shrubs. Just DON'T use Walnut (it has growth inhibitors). So far it's free for the hauling, but I've noticed the pallet plant isn't running as much as it used to, so supply is short right now. :frown: ~~ grnspot110
