Know before you buy
Unlike traditional lime, which can take a long time to break down and alter soil pH, Nutri-Cal is a liquid concentrate designed for immediate calcium availability. It bypasses the slow soil-reaction process to deliver calcium directly to the plant tissues where it is needed most.
Nutri-Cal is versatile and safe for use on vegetables, flowers, trees, and shrubs. It is particularly effective for fruit-bearing plants prone to calcium deficiencies like tomatoes and peppers.
For foliar spray applications, mix 3 ounces of Nutri-Cal concentrate per gallon of water. Ensure you cover the foliage thoroughly for the best absorption.
No, Nutri-Cal is formulated to be gentle on plants. When applied at the recommended concentrations, it will not cause the leaf burn often associated with harsher chemical fertilizers.
Yes, Nutri-Cal is highly effective at preventing blossom-end rot. By ensuring a steady supply of calcium reaches the developing fruit, it helps maintain cell wall integrity and prevents the tissue breakdown that causes rot.
No, Nutri-Cal is a mineral-based, non-organic fertilizer. It is designed for high-efficiency, targeted calcium delivery rather than organic soil amendment.
