Notes
The myths: Epsom salts do NOT make plants healthier in general; they help only where soil lacks magnesium. more than half of Georgia gardeners would see no benefit. Get a soil test before using it.Safety: Epsom salt is a laxative if swallowed; store it out of reach of kids and pets and label any mixed jug. Don't overapply; it adds salts that build up in soil and runoff.
