Is Epsom Salt Good for Tomato Plants?

Yes, not only is Epsom salt good for tomato plants it is a superfood! Growing tomatoes is mostly a labor of love; many gardeners swear by their tried-and-true tomato-growing methods. You may have heard that planting your tomatoes with eggshells, banana peels, and salts is a good idea.

There’s a lot of good science behind adding these things to your tomato when planting it. Egg shells are high in calcium, banana peels are high in nitrogen and potassium, and Epsom salt is high in magnesium, which is essential for plant growth.

Epsom salt is a naturally produced mineral compound composed of magnesium sulfate. It’s frequently recommended as a self-care item for aching muscles, cold symptoms, and medicated salves. Many gardeners also recommend applying Epsom salt to tomato plants because of its amazing benefits to vigor, health, and flavor. Let’s separate fact from fiction – the use of Epsom salt in the garden has some scientific support.

Magnesium and sulfur are critical for tomato plant growth and health and these micronutrients are required for photosynthesis, protein synthesis, and the formation of cell walls. So it stands to reason that applying Epsom salt to tomato plants will make them healthier.

However, there are exceptions and in order not to hurt your plants your must first do a soil test. Thus, broad statements about using Epsom salt in the garden may be misleading and harmful.

– It Enhances the Flavor of the Tomatoes

The importance of flavor when growing tomato plants. Nobody wants to harvest a pile of bland tomatoes – those can be purchased at the grocery store and you could save yourself some trouble!

Epsom salt application is one of several ways to improve the flavor of your tomatoes. For those asking how to fix magnesium deficiency in tomato plants here is what you need to know.

Sulfur and magnesium are both important plant micronutrients. Magnesium is essential for photosynthesis, and sulfur aids in producing enzymes and proteins –although they are only required in trace amounts, they significantly impact your plants’ health.

A steady supply and balance of all micronutrients, including magnesium and sulfur, is critical for plant health, which makes your tomatoes taste better. A small amount of Epsom salt added to your watering can before watering will make those essential micronutrients available to the plant, improving the flavor of the fruits when harvest time comes around.

– Epsom Salt Increases Nutrient Uptake for Your Tomatoes

Although magnesium and sulfur are required in minute amounts, lacking these micronutrients can stress the plant, limiting the uptake of other essential nutrients such as nitrogen and phosphorus. Nitrogen is required for healthy plant growth, while phosphorus promotes flower and fruit production. Without these elements, you may have a poor harvest, no harvest, or tomato plants that die before they even begin to fruit.Growing Tomatoes in a Garden Bed

According to research, applying Epsom salt to micronutrient-deficient soil can improve the uptake and utilization of these other important nutrients, thereby improving the overall health of your plants. Apply the salt to deficient soil before planting, or dilute in water and add as needed.

– Epsom Salts Increase Growth

It’s all about the micronutrients once again. When your tomato plants are given everything they require, they will grow normally and produce all the tomatoes you want. When certain nutrients are deficient, the plant cannot grow properly and will experience various problems.

This is particularly true of magnesium, and plants cannot photosynthesize without it, leaving them without fuel for growth. Even under ideal lighting conditions, a plant with low chlorophyll levels cannot process extra sunlight and convert it into chemical energy.

– Maintenance for Tomatoes

You’ll know if your tomato plants are deficient in magnesium if they have yellowing leaves. Do not sit back and let this happen! Add Epsom salt treatments to the soil as your tomatoes mature to prevent yellow leaves. One tablespoon of Epsom salt per foot of plant height is the ideal solution ratio.

If your tomato leaves plant grows two feet tall, you must feed it two tablespoons of Epsom salt at least twice a month! One on the 1st and one on the 15th of the month would be ideal. The general rule for other plants is once every six weeks.

Frequently Asked Questions

– Is Epsom Salt Good for Plants Other Than Tomatoes?

Yes, epsom salt is good for plants other than tomatoes – it may even be used for peppers, hostas, roses, and cucumbers. All these plants will benefit from an extra magnesium boost. Remember that it is only to be used when the soil is magnesium deficient.

Adding Epsom salts to soil with enough magnesium can harm your soil and plants by inhibiting calcium uptake. Additionally, leaf scorch can result from spraying Epsom salt solutions on plant leaves.Growing Pitcher Plants in a Garden

– What Plants Don’t Like Epsom Salt?

Plants that don’t like Epsom salts are pitcher plants, venus flytraps, and sundews. These are all insect-eating plants that should not be treated with Epsom salts since they are more adapted to grow in mineral-poor and depleted soil, even a little fertilizer could kill the bug-trapping ornamentals.


Each of these four wonderful benefits comes with a caveat that is critical to the success of your Epsom salt usage: The soil must be magnesium deficient. Therefore you need to know the following:

  • These advantages are only possible if your tomato plants are magnesium deficient and you use Epsom salts to replenish the magnesium levels.
  • Before using Epsom salts in the garden, a soil test is required.
  • If you’re unsure about a potential magnesium deficiency and can’t test the soil, using a general fertilizer in small amounts is considered safer.

That being said, while these benefits do have a basis in reality when there is a magnesium deficiency, some claims remain firmly in the realm of fantasy. Go on and treat your tomatoes!
