Gloria emailed me recently asking if Epsom salts really did any good for tomatoes and, if so, what other plants would benefit from adding a handful? Although gardeners have sworn by Epsom salts for years, there is really very little research based evidence that adding Epsom salts at planting or using it as a supplemental fertilizer makes any difference in how plants grow. Still, I always lean on the side of experienced gardeners. Sometimes it takes science awhile to catch up. If you’d like to try experimenting on your own, here are some tips for using Epsom salts in your gardens. And for the fun of it, take the poll and let’s see how many of you are already Epsom salt believers.
