There are many steps that take place in order to create the attractive coloring of dyed mulch. First, the mulch itself is aggregated in to large mounds. This usually takes place next to a hopper machine. Inside the hopper, the untreated mulch is sprayed with a colorant by a mulch dye machine. After this step, the processed mulch is removed via a conveyor belt to a stockpile area. For more information visit us at Cmcmulchcolorants.com.
