salt damage to soil
Hi Experts, Some of the soil along my sidewalk has damage from de-icer salts. I had the soil tested and the sodium levels were too high. Can I undo the damage by adding gypsum? If so, what are the details? If not, is there another technique your recommend?

Gypsum theoretically can be used to correct the high sodium levels, but its application is more for agricultural settings rather than home landscapes. To decrease the sodium level of your soil, you could simply just apply water. Soaking the affected area with one-inch applications of water three to four times in the spring can often treat plant damage from de-icing salts. Rainfall will move the salt out of the soil gradually too.
