Epsom salts are a great way to give your plants an extra boost of essential minerals, such as magnesium and sulfur. Many plants thrive when given Epsom salts because they provide essential nutrients that the plant needs for growth. It's important to note that not all plants like Epsom salts, so it is best to research the particular species you have before applying it. Generally speaking, some of the most common houseplants that benefit from this natural fertilizer include tomatoes, peppers, roses, geraniums and petunias. Additionally, many vegetables including squash and cucumbers also respond positively when given a dose of Epsom salt every few weeks during their growing season. Of course it's always best practice to read up on any plant’s specific needs prior to adding anything new into its environment; however for those who want an easy solution for nourishing their greenery with additional minerals then Epsom salt may be just what you need!
