Can You Mix Epsom Salt With Fertilizer? – Swipe Garden Style

Epsom salts, also known as magnesium sulfate, are a simple technique to enrich garden soil. They boost plant health by adding sulfur and magnesium to the soil. But, can you mix Epsom salt with fertilizer?

The answer is yes. Gardeners combine it with liquid fertilizer and use it as a foliar spray or soil drench.

The way they are combined and administered depends on your individual needs, and the outcomes may vary.

Let’s dive right into the details!

Can You Mix Epsom Salt With Fertilizer?

Epsom salts appear widely to feed plants that require magnesium, such as peppers, tomatoes, and rose bushes. 

People often mix them with liquid fertilizer or water, put them around the bottoms of plants, or sprinkle directly on the leaves. This procedure results in more prominent blooms and fruit.

It increases flower blossoming as well as the leaves color. This substance also helps aid bushier plants to grow better. This crystal consists of hydrated magnesium sulfate, which is important for plant development.

This element helps plants absorb essential minerals like phosphorus and nitrogen more effectively. It also aids in the production of chlorophyll, a necessary component of photosynthesis. 

This substance will assist if the soil gets magnesium deficient. Moreover, unlike most chemical fertilizers, it carries no risk of abuse, so you may safely use it on practically all of your garden.

How Do You Use Epsom Salt In Fertilizer?

Before using this substance, get your soil checked to see if it’s magnesium deficient. You should also notice that many species, such as beans and green vegetables, may thrive and produce in low-magnesium soils. 

Species such as roses, peppers, and tomatoes, on the other hand, require lots of magnesium and are consequently irrigated with this salt. When mixed with liquid fertilizer, plants absorb this salt, primarily when used as a foliar spray. 

Once a month, sprinkle most plants with a solution of 2 tsp (30 mL) Epsom each gallon of water. Decrease this to 1 tsp every other week for more regular watering (15 mL). 

Spray in the spring as soon as the leaves show and again after the flowers have bloomed. Apply 1 tsp Epsom crystals around each plant or sprinkle when transplanting after the first blooming and fruit setting for peppers and tomatoes.

Magnesium sulfate levels that are too high might induce salt damage in plants.

Overuse has been related to less beneficial microorganisms colonizing the roots, such as nitrogen-fixing bacteria. 

Furthermore, too much soil magnesium can cause aluminum to leach out of the soil to harm elements available to aquatic systems and plants. 

As a result, adding this substance might produce an unbalanced and hazardous habitat for thriving species. However, it is highly soluble. So, it does not stay in the ground for long.

What Do Epsom And Baking Soda Do For Plants?

Baking soda has no side effects on plants, and it can help reduce fungal spore growth in some situations. It works best on vegetables and fruits that are picked off the stem or vine.

Regular treatments in the spring can help prevent illnesses like powdery mildew and many other foliar problems. In a liter of water, combine 1 tsp baking soda, 1/2 tsp clear ammonia, and 1 tsp Epsom salt. 

Mix thoroughly, then feed each plant a cup of the liquid. This solution will act as a fertilizer to help wake up, reinvigorate slow-growing plants.

Beans And Vegetables Do Not Like This Substance

Many species, such as beans and green vegetables, may thrive and produce in low-magnesium soils. So, they do not like this substance.

However, if you notice that your plants are magnesium deficient, you could believe that the problem is with your soil. 

Some species have magnesium deficits due to too much phosphorus in the soil, hindering the plant from properly absorbing the magnesium. 

In this case, applying Epsom salts may have no effect since the phosphorus content in the ground must be reduced for a plant to acquire magnesium.

The Bottom Line

Applying Epsom salt to your garden benefits the plants. However, remember to check the soil condition before doing so to avoid magnesium deficiency.
