Watering a most plant species with salty or brak water will kill them.
Plants absorb water from the soil by osmosis. Osmosis is a flow of water molecules from a solution with lots of "pure" water to a solution with lots of solvents - across a semipermeable membrane (which in the case of the plant is the cell membranes of the root cells).
Normally there are more solvents in the water inside the plant (a higher concentration), so water flows into the root hair cells from the soil.
Watering the plant with salt water changes the "osmotic potential" of the soil - making the water surrounding the root more saline than the cell sap within the plant. This leads to reverse-osmosis, where the nutrients are actually drawn out of the plant and into the soil.
In the short term this leads to wilting as the plant is not able to absorb enough water to sustain metabolic functions. Then nutrient deficiencies become apparent in the plant. Eventually the plant may die.
Average bottled water contains about 300 parts per million (ppm) of dissolved salts. The majority of plants can withstand concentrations up to about 1200 ppm of dissolved salts. Plants that grow in alkaline soils can take up to about 2500 ppm. One of the most salt resistant plants is the Date Palm, this can take salt levels up to 12,000 ppm. Sea water contains about 35,000 ppm of dissolved salts.
There are a group of plants known as halophytes which are adapted to growing in very salty water. These are common to coastal areas and salt marshes.

∙ 14y agoIt usually depends on the type of plant. If it is a form of seaweed then obviously no, but if it isn't then it most likely will. When plant cells take in too many salt molecules the cells shrivel up making the plant unhealthy and usually leading to death. It is the same when over watering. If the plant engulfs too many water molecules the cells expand and burst.

∙ 15y agoThe roots of a plant take in water from the soil by way of "osmosis", where water moves through a semi-permeable membrane. Water molecules can pass through, but not larger (dissolved) molecules. But since water actually flows both in and out, in both directions, the plant needs a surplus moving to the inside. High concentrations of dissolved substances in the ground water (solutes) tend to block the inward flow and prevent the plant from absorbing enough water to sustain its life processes.

Salt is not bad for plants unless used accessively. Just like anything. To much of anything at one time will eventually do it in.

Is salt harmful to the soil?
Most plants won't grow in soil has salt in it. Some plants will still grow, there are often the types of plants you see growing near the beach.
What do plants absorb from the soil?
Nutrients and water.
What is saline soil?
salt content in the soil that reduce fertility
Why is it important to keep salt out of the plants' soil?
because the salt is of couse too sour for the plants than it makes them dehydrated and weak....thats all i knoe...
Does acidic soil affect germination of seeds?
Yes. If the soil is too acidic it can kill the seed. It depends on the type of seed and where it was originally meant to grow. Some plants like alkaline soil and some like base soil.
Will morton's household salt kill tomato plants and pepper plants in the garden?
The short answer is YES. Putting any type of salt in or on the ground sterilize your soil and will kill any and all plants. Unless you want to render your soil useless for growing anything it is recommended that you DO NOT put salt in your garden.
Why does salt water kill plants on farms near the coastlines?
the salt content in the water when mixes with the soil or when it deposits on the foliage it will not allow the plant to get enough breathing gas(co2),thus the plants are killed. only few plants which can tolerate the saline soil can survive in coastal regions.
Do plants need salt in there soil?
no
Why cant we water our gardens with salty water?
The salt will kill all the plants and nothing will grow in that soil...ever again. Some plants "tolerate" some salt spray, but even those do better without it.
What do salt do to the soil?
Salt is a contaminant for soils because many plants doesn't accept too much salt in soil.
Is salt harmful to the soil?
Most plants won't grow in soil has salt in it. Some plants will still grow, there are often the types of plants you see growing near the beach.
Would salt be a good herbicide?
While salt will kill plants it is not a good idea to use it as not only will it kill everything it comes in contact with, I have heard that it can also sterilize the soil and you will have difficulty growing anything in the area treated.
Why does salting kill plants?
Road salt can kill plants because it draws the water out of them. Salt is a substance that absorbs water.
How does the removal of plants contribute to soil salinity?
Plants' roots hold the soil together so that the salt can not raise up. But when we harvest our crops, the soil is left and salt can easily come up.
Why don't plants grow well with salt?
The salt kills the nutrients in the soil.
Will salt or vinegar prevent plants from growing in soil?
Yes. Salt will. The Romans did it to the Carthaginians. :]
Will salt kill a plant?
plants are not slugs
