What potassium does in the garden

Potassium helps regulate water use, strengthens stem structure, and supports energy transfer within plant tissues. In soils with limited potassium, plants may show slower growth or reduced resilience to stress. Supplying potassium through a targeted soil amendment can help create a more robust root zone and steady nutrient uptake during the growing season.
