Answer: Basically, epsom salts are used as a source of magnesium and if applied, are used as a side-dressing or foliar spray during the growing season. Certain crops, including peppers, tomatoes and roses,
sometimes benefit from the additional magnesium. However, as long as your peppers are growing well and soil tests have not indicated a lack of magnesium, I wouldn't worry about it. If you would like to run some soil tests, your local County Extension will be able to help you with both the tests and analyzing the results. Their telephone number is 429-7085.
