This potassium silicate supplement works wonders in producing stronger, more resilient and structurally sound plants. It works as a “cement”, protecting individual cell walls.

Not only does it prevent damage from getting in, it forms barriers which promote water retention. This is crucial for withstanding droughts and high temperatures.

Source of essential potassium

Sturdy Stalk provides potassium: it’s the “K” in NPK and is essential for any plant. Potassium aids in the transportation of water and nutrients. It’s also key in activating the enzymes that produce proteins and starches, which plants store as an energy source.

Enhances fruit and flower pigments

As well as strengthening your garden from the inside out, Sturdy Stalk plays a role in bountiful blooming.

Potassium helps fruits and flowers to form. It’s also found in cell sap – and the more cell sap is found in a plant, the more pigments it can store. This means that Sturdy Stalk encourages bright, vibrant blooms.
