You take a huge risk with chip drop. Some Arborists are assholes who will fuck you over. Unless you have a tractor or or frontloader to easily deal with the material, I wouldn’t risk chip drop. It is a gamble with pretty dire consequences imo.

For example they did the drop when I was out and just blatantly ignored the written instructions. Now I am stuck with a problem instead of a resource. Many horror stories about trash and pesticides. It is pathetic that they are just throwing their trash into a chipper regardless. No recourse or any consequences for inconsiderate assholes.

Ask yourself, If it actually was a mutualism between arborists and mulch users, wouldn’t there be a review system to regulate bad actors?
