Why calcium and boron?
Calcium (Ca)
- Builds strong cell walls, reducing disease and stress damage
- Supports root and shoot growth, leaf expansion and fruit firmness
- Helps nutrient uptake and movement within the plant
- Improves shelf life and texture; helps prevent blossom end rot and tip burn
Boron (B)
- Regulates cell wall formation and stability
- Supports pollen tube growth, fertilization, seed and fruit set
- Helps sugar movement and carbohydrate metabolism
- Prevents cracked or hollow stems and misshapen fruit
Why choose Boro-Cal?
- Fast correction - liquid form gives uniform coverage and quicker uptake than dry or granular products.
- Dual action - calcium and boron together in a balanced ratio; boron also helps calcium move within the plant.
- Flexible use - foliar spray for quick correction at flowering and fruit set, or soil application for season-long supply.
- Convenient - mixes with most fungicides, insecticides and fertilizers, saving spray rounds.
