The Hi Yield Calcium Nitrate is for use on tomatoes to help stop blossom end rot from occurring. We are unsure if it would do anything for apples or the bitter pit you are referring to. Our team does not have experience in bitter pit or what would cause or eliminate it, so we would recommend reaching out to a local fruit tree nursery or your counties master gardeners office for assistance with this particular problem.
Hi-Yield Calcium Nitrate does not have instructions on the product label for application in hydroponic systems so we are unable to recommend this use with the product.
Hi-Yield Calcium Nitrate is not labeled for lawns and should only be used in vegetable gardens to help prevent Blossom End Rot in especially tomatoes and peppers. You may wish to contact the manufacturer directly for clarification by either calling 855-270-4776, or by emailing [email protected]
Please take a moment to view our How to Select the Best Fertilizer for Your Lawn Guide and Spring Fertilizer Guide for more information on selecting the best fertilizer for your lawn.
Hi-Yield Calcium Nitrate is applied dry only to the root growing area of the plant and then watered in per the product label. It cannot be applied in any type of irrigation/fertigation system.
