In a method of treating a particulate landscaping material, the material is fed into a mixing chamber and an additive mixture including a functional additive and a carrier is delivered to spray nozzles within the mixing chamber. At least one of the spray nozzles is operated to direct an atomized spray into the mixing chamber. The material is agitated within the mixing chamber during and/or after directing the atomized spray into the mixing chamber. The material is then conveyed with the additive mixture applied thereto to a mixing chamber outlet. During these steps, a volumetric flow rate of the particulate landscape material through the mixing chamber is intermittently determined. The determined volumetric flow rate is intermittently compared to a predetermined target flow rate of the particulate landscape material. Based on this comparison, the volumetric flow rate of the particulate landscape material through the mixing chamber is adjusted.
