Saltwater destroys soil and vegetation instead of facilitating its existence. And you’d need to add better soil and the means to produce more fertile soil (plant species that shed leaves often and have nitrogen-fixing microbes in their roots).
But such water would make rain in the surrounding area more likely and common, if it can be sustained. For instance, I hear there are plans to re-create an inlet in northern Libya that used to exist but dried up when it was cut off from the Mediterranean by an earthquake that pushed up a natural dam some 6000 years ago or something, so the surroundings can become greener. (But given the current flooding of roughly that same area, doing so would be a terrible idea for the people who now live in that below-sea-level area.)
