Bolster® Biostimulant - Liquid Plant Growth Supplement
BOLSTER Plant Biostimulant - Ascophyllum nodosum seaweed, humic acid, and soluble carbohydrates. BOLSTER from Suståne prepares plants for stress conditions, increasing root mass and depth without a flush of top growth. BOLSTER has demonstrated improved drought resistance, increased chlorophyll production, and delayed senescence. It also increases plant salt tolerance in saline soils and irrigation water high in salts; increases plant health and vigor to offset infection of certain diseases and to guard against the effects of plant-parasitic nematodes. Chelated iron and plant hormones in BOLSTER enhance seedling establishment and improve color.
