How to Add Epsom Salt to Tomato Plants in a Biology Lab

If you want to grow delicious tomatoes in your biology lab, you should use everything at your disposal to protect those plants from damage and keep them healthy and strong. As with any ingredient for horticulture success, it is important to use Epsom salts correctly to ensure maximum effectiveness. Epsom salts aren't particularly effective for increasing yield, but can be quite helpful at recuperating plants with magnesium deficiencies.

Instructions

    • 1

      Check your plants for a magnesium deficiency. Plants suffering from this common malady often have yellow coloring in their leaves and may drop their lower leaves. If your plants aren't experiencing a mineral deficiency, Epsom salt may not be your best choice.

    • 2

      Measure your tomato plant from the soil to the top tip.

    • 3

      Add 1 gallon of water to your watering can.

    • 4

      Drop 1 tablespoon of Epsom salt per foot of your tomato plant’s height into the watering can.

    • 5

      Add 1 tablespoon per foot for each individual tomato plant. For example, two three-foot tomato plants would require 6 tablespoons of Epsom salt.

    • 6

      Water your tomato plants with the Epsom salt mixture once every two weeks.
