    Outdoor Plants

  1. 1

    Add 2 tbsp of Epsom salt to each hole before planting your seeds. This is recommended for plants such as tomatoes.

    Sprinkle 1 tsp of Epsom salt around the base of the plant for each foot tall the plant currently is. If you have a plant that is 2 feet tall, then you would sprinkle 2 tsp of Epsom salt around the plant.

    Press the Epsom salt into the soil around the base of the plant by scratching with your fingers or gardening gloves.

  4. 4

    Repeat monthly.

    Indoor Plants

    Mix the two ingredients and then pour some of the mixture into a watering can.

    Pour over the houseplants once every two weeks. Use regular water in between.

Tips and warnings

  • If your houseplants are thriving, you can cut back the Epsom salt solution to once per month.
  • If the soil you are using is not deficient in magnesium, you do not need to use the Epsom salts.
