Calcium Boost
Calcium Boost is an advanced soluble calcium supplement that corrects calcium-deficiency disorders such as blossom-end rot, fruit cracking and bitter pit. Absorption-enhancing compounds carry calcium through the cuticle to developing fruit, reaching tissue that ordinary mineral calcium sprays cannot.

Why do calcium disorders happen even with calcium in the soil?
Calcium moves poorly within the plant and depends on steady transpiration to reach fruit. So disorders like blossom-end rot, cracking and bitter pit appear in the fruit even when soil calcium is adequate - the calcium simply is not getting to the right tissue at the right time. The fix is not more soil calcium but getting calcium directly into the developing fruit.
How does Calcium Boost reach the fruit?
Calcium Boost (calcium chloride 8.2% with protein hydrolysate and phytic acid) pairs highly soluble calcium with absorption-enhancing compounds that help it penetrate the cuticle and reach developing fruit. This is what lets it correct disorders that conventional mineral calcium sprays - which often sit on the surface - cannot reliably address.
When and how should it be applied?
Apply as a foliar spray during fruit development, when calcium demand peaks and the sensitive window for disorders is open. Repeated applications through that window keep calcium supplied as the fruit grows. Early, consistent application is far more effective than trying to correct a disorder once symptoms appear.
Which crops and disorders is it for?
Calcium Boost targets calcium deficiency, blossom-end rot, fruit cracking and bitter pit, and has been tested on tomatoes, peppers, apples and stone fruit. These are the classic calcium-disorder crops where a few affected fruit can downgrade a whole block.
How does it protect fruit quality?
By delivering calcium into the fruit during the critical development window, Calcium Boost strengthens cell walls and reduces the physiological disorders that cause culls and downgrades. The protein hydrolysate and phytic acid support uptake, so more of the applied calcium ends up doing useful work in the fruit.
