Sturdy Stalk strengthens plant cell walls to support heavier harvests and crop resilience with our potassium silicate supplement.

Sturdy Stalk, Emerald Harvest’s premium potassium silicate supplement, is a valuable addition to your feeding program at crucial stages in the crop life cycle when fruits and flowers are putting on girth and weight. The silica in the formulation helps increase the rigidity and thickness of plant cell walls, making your crops sturdier. Sturdy crops can better withstand environmental stressors and support heavy yields. Sturdy Stalk also helps increase the potency of harvests and gives an added boost to blooms with its 0-0-1 NPK.
