How To Use Epsom Salt For Sweeter Tastier Tomatoes

epsom salt for tomato plants

You’ve probably heard of using Epsom Salts for personal hygiene. However, epsom salt and tomato plants may be something new. It’s true, epsom salt can also be used in the garden!

What Is Epsom Salt?

First of all, Epsom salt is not salt. It is NOT something you can put on your food!

It’s actually a compound called magnesium sulfate that occurs naturally. The name Epsom is a nod to a saline spring found in a part of England by the same name.

Magnesium sulfate is known for providing wonderful benefits when growing tomatoes,  functioning as a plant fertilizer.

Incorporate Epsom Salt And Tomato Plants From The Start

#1 For Potted Tomato Plants

Dissolve around 2 tablespoons of epsom salt in 1 gallon of water. Use the solution to water your plants. No need to do this every day though! Instead, use the solution once a month and switch to regular watering for the rest of the days.

#2 When First Planting Tomato Seedlings

When first planting seedlings in the garden, take 1 cup of Epsom salt and sprinkle it liberally over the plot. Ideally, 1 cup of Epsom salt will cover roughly 100 square feet. Make sure you distribute it evenly.

When you’re done, work the epsom salt into the soil. This makes it easier for your tomato plants to obtain nutrients from the soil, building stronger root and burst into healthy blooms.

#3 Tomato Plant Maintenance

Generally, you’ll know if your tomato plants are suffering with a magnesium deficentcy as the leaves start to become yellow. Do not wait for this to happen! As your tomato plants mature, add a bit of Epsom salt to the soil.

The ideal ratio is 1 tablespoon per foot of plant height. If your tomato plant is two feet in height, you’ll be feeding it two tablespoons of Epsom salt at least twice a month!

Once on the 15th and another on the 30th would be perfect. For other plants, the general rule is once every six weeks. Opt for the less frequent method and observe how your plants react.

Warning: DO NOT over use!

#4 Applying Epsom Salt As A Soil Drench OR A Foliar Spray

Drenching with Epsom salt improves the overall health of tomato plants by giving them a good dose of magnesium. If your tomato plants need a boost, dissolve about one or two tablespoons of Epsom salt in a a gallon of water. Drench at the base of the tomato or pepper plants and allow the water-salt solution to soak into the ground. Repeat throughout the season as necessary.

Apply as a foliar spray using the same 1 or 2 tablespoons in a a gallon of water, every 2 weeks for a boost.
