That's one way to control it. And by the way, I do not condone eating the plant without caution. Consider all parts of the plant toxic to some degree. Every garden season has its important hypes. A few seasons ago, it was Epsom salts, and gardeners are asking questions about it again.
Epsom salts is another name for magnesium sulfate.
For years, it has been widely used as a pharmaceutical and as a foliar spray to correct magnesium deficiency in certain fruit and vegetable crops. Responsible people never recommend it be used as a matter of course, but only to correct a magnesium deficiency. This nutrient is never deficient in Montana soils, and using Epsom salts in your garden on a regular basis could interfere with the plant taking up other nutrients. In other words, you'll be creating more problems. Leave it alone unless a foliar analysis indicates you have a real magnesium deficiency.
