Atrimmec® Plant Growth Regulator is a systemic plant growth regulator that works by blocking the plant hormones that stimulate growth. Applied to shrubs, hedges, trees, and groundcovers, Atrimmec reduces trimming and pruning labor by 50% or more, and can improve the appearance of landscape ornamentals when applied as a foliar spray. It’s also labeled for bark banding and soil drench applications, and a single application of Atrimmec can prevent undesired fruit for the season on certain landscape trees.
