EMERALD HARVEST STURDY STALK 6 GALReturn to Shop
Build up your plant cell walls and encourage productivity with Sturdy Stalk, a potassium silicate supplement from Emerald Harvest. Sturdy Stalk’s key ingredient—silica—fortifies your plants and enriches the internal structures needed to support top-heavy plants laden with flowers and fruits. Because it strengthens cells, silica helps plants withstand environmental and other stressors, so that they spend more of their energy creating blooms and buds. This results in a productive, vigorous garden with heightened resistance to pests, insects and pathogenic airborne and waterborne diseases.
