Salt makes an excellent weedkiller and slug control but...... it can be very dangerous to the soil and beneficial earthworms.

Earthworms breathe through their skin taking in oxygen and expelling carbon dioxide. They do this by secreting mucous which keeps their skin moist. Salt destroys their skin so they cannot breathe.

Earthworms and their castings are the best natural fertilizer for the soil.

Slugs can be controlled in many other natural ways without chemicals.
