What's CalSi Made Of?

Calcium
Helps strengthen plant cells and supports steady growth. Because plants can’t move calcium around once it’s absorbed, a consistent supply is important for healthy new growth. A lack of calcium can cause poor growth, distorted leaves and flower or bud drop.

Magnesium
Essential for photosynthesis, helping plants turn light into energy. Low magnesium can lead to yellowing leaves, slow growth and reduced plant performance.

Silicon
Strengthens plant tissue, helping plants grow sturdier and more resilient. It supports healthy new growth and reduces deformities in leaves and stems.

Ocean Minerals
Naturally rich in trace elements, ocean minerals help improve soil health, plant strength, flavour and nutrient density. They also support beneficial soil microbes and help plants cope with stress. How to Use:

Use once or twice a year (about every 6 months).

Sprinkle directly onto the soil surface

Gently work into the soil or water in well
