Dealing with mulch can be "pokey" with shards and splinters puncturing nylon and nitril so I tend to lean towards leather gloves for that task. Here are my favorite choices.
Tillman 1424 - Limbing, pruning, brush cleanup, mulch spreading.
Tillman 1761 Nitrile Rubber Coated - weeding, dead heading roses, light duty tasks.
I get these at my local Airgas, Matheson, Praxxair or any welding supply house in your town.
