One effective way to add calcium to plants, particularly when they show signs of deficiency, is through foliar spray.
Using Foliar Sprays for Calcium Deficiency
When your plants need a quick boost of calcium or are exhibiting clear signs of deficiency, applying calcium directly to their leaves via a spray is a rapid method. According to information from November 5, 2021, you can add calcium via a spray that contains specific calcium compounds.
What to Use in the Spray
The reference indicates that a foliar spray can contain:
- Calcium chloride
- Calcium acetate
- Calcium nitrate
These compounds provide calcium in a form that can be absorbed by the plant's leaves.
How Foliar Sprays Work
Applying calcium as a foliar spray offers several benefits:
- Quick-Acting: This method is quick-acting, meaning the calcium becomes available to the plant relatively fast compared to soil applications.
- Direct Absorption: Plant leaves absorb the calcium directly from the spray solution.
- Targeted Treatment: It is particularly useful on plants showing an obvious and pronounced deficiency of calcium. This allows you to address the issue directly where symptoms are visible.
This method provides a way to bypass potential issues with soil pH or root uptake that might be limiting calcium availability from the soil.
