Gypsum - Knowledgebase Question

Corpus Christi, Te
Question by leenei

I didn't get a clear answer previously. I use well water with 20 ppm salt to water the flower beds and potted plants. Over time I know this causes a salt buildup. Will gypsum help to neutralize this salt buildup, or what do I use? I'm not interested in using lime as in the previous answer.

Sorry the answer wasn't clear! Gypsum improves sodic (saline) soils by
removing sodium from the soil and replacing it with calcium. Use a granular type and spread at the rate of 40 pounds per thousand square feet.
