Does anyone know how to "sweeten" soil that has had salt on it?

I planted my usual Vinca bedding plants, in the front of my flower garden. They all died, quickly. Then I tried another variety of annuals. They died. A garden employee at Lowes asked me if the flower bed was close to a sidewalk that may have had salt on it to melt snow. BINGO ! YES. Help!!!

    Salt doesn't disappear from the soil until it is sufficiently wetted over time to reduce the salinity as it goes down to the water table. You may have to replace the soil so that the roots will not have to deal with the salinity that will kill anything. Perhaps you could put a taller closed edging so that when you shovel or blow the snow the salt will not get into it and make sure the snow is shoveled or blown away from the garden area in the future to prevent the salt from getting into garden. We have hostas along our sidewalk and we make sure that the snow is blown over the garden. We have to salt, as there are some low areas on the sidewalk that glaze over all the time with ice. I hope this helped you , Gloria. So sorry you had to lose so many plants before you found out what the problem was caused by.

      For now, you could also put some potted plants on the area, they would be safe since the salt will not be in the potted soil and they should do fine until you can get fresh soil into the area. Once that is done, you should be able to plant them where they should be, in the soil. I hope that replacing the soil makes the area healthy again. Just avoid getting salt in the area and keep away any shoveled or blown snow off the garden area and you should be fine.
