How much epsom salt for pepper plants is enough to grow juicy and healthy peppers is something many veggie gardeners want to know. Just one to two tablespoons of this salt, added once a month in any form, will resist magnesium deficiency and prevent blossom end rots from developing in peppers.How Much Epsom Salt For Pepper Plants

Vegetable gardeners have been using this salt to grow peppers for a long time, and their yield only gets better every year. Read below to find out how much salt to use and in what form to grow the best peppers ever.

How Much Epsom Salt Should You Use for Pepper Plants?

You should use one tablespoon of epsom salt per foot of pepper plant’s height added to the base. Do this every sixth week till it is time to harvest the fruit. Water plants with one gallon of water mixed with two tablespoons of epsom monthly.

Epsom salt has been used for centuries and is known as gardening’s best-kept secret. It is magnesium sulfate and should not be confused with ordinary table salt, which is sodium chloride.

It is composed mainly of sulfur but also contains a significant amount of magnesium and traces of oxygen. This mineral is nothing short of a holy grail for plants that need a lot of magnesium for their growth, like peppers, tomatoes, and eggplant.

– Epsom Salts and Peppers

This salt helps a lot with growing peppers at home. You can add epsom salt directly into the soil when sowing seeds to speed up seed germination. It also helps regulate the soil pH by neutralizing it if it becomes too alkaline.Epsom Salts and Peppers

As soon as the plant starts forming peppers, this salt needs to be added to the plant’s soil. This will ensure that the plant produces a lot of peppers that are all large and healthy. Epsom salt also prevents blossom end rot from developing in tomatoes and peppers.

How to Use Epsom Salt for Growing Peppers?

To use epsom salt for growing peppers, carry out soil testing first. Then add one tablespoon of salt into the dug hole before planting this plant or its seeds into the soil. As the plant grows, water it with epsom foliar spray every month.

– Carry Out Soil Testing First

Before planting peppers, carry out a thorough seed testing of your soil. This test can be performed using home testing kits available easily online. Alternatively, collect a soil sample and have a nearby laboratory check it out.Soil Testing for Pepper Plants

This way, you can identify what your soil’s pH is and the nutrients it lacks. If there isn’t enough magnesium in the soil, then feeds made of epsom salts are a good option. Sometimes, you will have to opt for a more balanced fertilizer instead.

– At the Time of Planting

Whether planting seeds or transplanting a grown plant in new soil, add this salt to help boost growth. Add just one to two tablespoons of bath salt to each hole you have dug for seeds or adult plants.

One tablespoon contains about 21.25 grams of this salt, and two tablespoons contain approximately 42 grams. When used directly like this, this salt behaves like a soil additive and helps the plant’s roots to establish faster.

– During Fruiting Season

As these plants grow and produce fruit, you can use epsom salts as a regular fertilizer. Collect one gallon of filtered water in a bucket and mix two full tablespoons of salt. Once a month, spray the plant using this homemade liquid fertilizer instead of regular watering. It is ideal to start practicing this when the blooms first appear until it is time to harvest the peppers.

– As a Side Dressing

Side dressing means adding salt crystals directly into the soil around the plant’s base. As soon as the plant starts blooming, add this salt as a side dressing every fifth to sixth week until harvest. Measure the height of the plant and add one tablespoon of salt per foot each time.

How Does Epsom Salt Benefit Pepper Plants?

Epsom salt benefits pepper plants and others by providing them with magnesium and sulfur. These micronutrients are essential for healthy plant growth, nutrient uptake, and pest control. Only a tiny quantity of this salt is needed, making it cost-effective too.

– It Decreases Soil Alkalinity

These plants grow when the soil pH is between 6.7 to 7.0. This means they like their soil to be neither acidic nor alkaline. pH testing kits are widely available at any department store and will help diagnose if the soil has gotten too alkaline. Adding the correct quantity of epsom salt will help neutralize and bring it back.

– It Helps With Nutrient Uptake

As mentioned earlier, this salt is rich in a micronutrient called magnesium. Let us not take magnesium lightly just because plants need it in small quantities. This nutrient is responsible for helping plants absorb all other nutrients through their roots.Epsom Salt Helps With Nutrients

It helps them take up nitrogen, phosphorus, and potassium, and all macronutrients. The trick is to apply epsom salt to the plants and soil at the start of the growing season. This way, the plants can access all the nutrients from the start and grow the healthiest vegetables.

– Turns This Plant Greener

If your pepper or tomato plants suffer from yellowing leaves, adding epsom salt might help. It provides the plant with a large amount of magnesium, an essential building block of the chlorophyll molecule.

Remember that chlorophyll gives plants their green color and carries photosynthesis for it. So not only will your pepper leaves appear greener, but they will also be more extensive and healthier. Many studies have shown that peppers grown with this salt are larger and juicier than those produced without it.

– Balances Nutrient Levels

If your plants and vegetables have not been growing well despite the best care, something might need to be fixed with your soil. Either carry out soil testing at home or send the samples to a creative lab to find out what is missing. Magnesium is usually the number one element found depleted in vegetable soils.

This is because most vegetables like pepper and tomato plants need this nutrient to grow juicy fruits. Luckily, epsom salt is rich in magnesium and can be used to balance the depleted nutrient levels in the soil.

– Is a Pest Deterrent

This salt is a top home remedy against several common pests in the vegetable garden. It is effective against garden beetles, aphids, and mealybugs. A spray solution made of epsom salts should be adequate for these minor bugs. Mix one whole cup of salt in five gallons of water to kill these pests.Pest Deterrent Epsom Salt

For sizable pests like snails and slugs, sprinkle a handful of salt around the plant in a neat circle. Snails and slugs do not like the texture of salt and get itchy from it. If rodents like mice and voles are digging holes all over the lawn, pour salt into their burrows to get rid of them.


– What Plants Don’t Like Epsom Salt?

Plants that don’t like Epsom salts as a feed in any way or form are carnivorous plants. Some famous examples of these plants are sundews, pitcher plants, and the venus flytrap. They prefer soil that’s poor in nutrients, so adding fertilizers like bath salts has been observed to kill them.

– Which Plants Like Epsom Salts?

Plants that like epsom salts are those who have a high magnesium demand, such as peppers, tomatoes, roses, and lettuce. Grass also likes being fertilized with this salt occasionally. In your home garden, epsom salts also benefit legumes, hydrangeas, and succulents.


Just one to two tablespoons of epsom salt every month will help your plants grow successfully. Remember these points before you begin to carry out the procedure.

  • Two tablespoons of this salt equal 42 grams and must be added to the soil monthly.
  • Another option is to take one gallon of pure water and directly add two tablespoons of bath salts.
  • If your soil lacks magnesium or is too alkaline, using this salt will solve both problems.
  • A fistful of salt sprinkled all around the base of the plant will stop snails and slugs from coming near it.

In this article, you learned how much epsom salts will be needed to grow the best quality peppers you can hope for. Try out the methods discussed here, and hopefully they turn out well for you.
