Does salt water help plants grow?

Answer 1

Answer:

There are many folk-cures and hear-say remedies for growing plants, many if not most will end in weakening if not killing the plant, the best recourse is to know the plant, know what type of soil it likes, and what kind of nutrients it requires, (well balanced nutrient filled diet) the simple course of action would be: Plain Water, Air, Sunlight [full/partial/defused] and a mild form of fertilizer, keeping in mind not to over water or under water.

Answer 2

Salt affects the growth of many plants, but not all.

The higher concentration of salt outside of the plant cells in the soil causes water to move outside of the cells to try and equalize the concentration. Some root cells of plants that do not tolerate salt may die, and if bad enough the plant will die. The damage gives the plant a burnt look, often on the leaf edges first. The same thing happens with too much of any mineral.

Some types of plants, such as mangrove trees, can tolerate higher levels of salt and not be damaged. Their cells have a high concentration of salt already in them so the water doesn't move out. Some even separate salt from the water and excrete it through their leaves, roots, and branches.

The most common Herbicides are salt based glyphosate products.

Using salt water to fight forest fires does large amounts of damage to plants, particularly in Australia where fire is an important part of native plant regeneration.
