Three experiments were designed to examine whether foliar fertilization had an effect on the invasion and establishment of annual bluegrass ( Poa annua L.) (AB) and silvery thread moss (Bryum argenteum Hedw.) (STM) onto creeping bentgrass (Agrostis stolonifera Huds.) (CB) putting greens in temperate climates. Greenhouse experiments showed that foliar fertilizer increased the nitrogen concentration of both AB and CB compared to soil-applied fertilizer. Foliar fertilizer also promoted the invasion and establishment of STM in the greenhouse compared to granular and soil-applied liquid. Fertilization using ammonium sulphate as the nitrogen source resulted in plants with a higher root and shoot mass compared to a fertilizer with urea as the nitrogen source. The field study conducted at the Guelph Turfgrass Institute (GTI) found that overseeding with CB T-1 and applied granular fertilizer resulted in a higher CB population compared to foliar. Soil-applied fertilizer resulted in the highest root production for both AB and CB at 3-6 cm and 6 cm and below in the soil profile. Microscopic examination revealed that AB may have the ability to absorb foliar fertility through barb-like extensions on the margins of the leaf, while CB cannot
