Epsom Salt For Palm Trees: Yes or No?  

We all would like to have a palm tree from a holiday brochure in our backyard. But the reality is quite different. Palm trees are living organisms that need special care. They require an adequate amount of nutrients to thrive, just as we humans do. 

Since most palm trees don’t grow in rich soil, we have to regularly fertilize them to keep them healthy. Using Epsom salt is one way to ensure your palm trees are getting enough magnesium

What Is Epsom Salt?

Epsom salt is magnesium sulfate. It is a mineral compound made of magnesium and sulfur. It has many benefits and uses in medicine and agriculture

It can be used to treat constipation, muscle aches, and magnesium deficiency in humans and plants. Plants like tomatoes, potatoes, carrots, roses, and palm trees can especially benefit from Epsom salt. 

Epsom salt is odorless, and it doesn’t significantly change the pH of the soil, which is a big plus. It is overall a great supplement for magnesium-hungry plants.

Epsom salt is good for palm trees when they are deficient in magnesium.  

Magnesium plays an important role in the production of chlorophyll, which is what is responsible for the natural green pigment in plants. In other words, magnesium helps give your palm trees that beautiful green color. 

If the leaves of your palm trees are slowly turning yellow, you may need to enrich the soil with magnesium by using Epsom salt. Think about it as giving your palm trees a magnesium supplement that will stop further damage. 

How To Use Epsom Salt For Outdoor Palm Trees?

Spread 2 to 4 pounds of Epsom salt uniformly over the root zone per palm tree, depending on its size. 

There are no specific guidelines, but 2 pounds of salt should suffice for a tree that’s close to 10 feet tall, and the maximum amount is plenty for an older, 24-foot palm. 

After you’ve distributed the salt, soak the treated area with plenty of water to ensure the Epsom salt gets dissolved and absorbed easily

I recommend you repeat this process four times a year during the growing season to stop the discoloration of the leaves. 

If you have lots of palm trees that need supplementation, it is best to buy Epsom salt in bulk. This 19 lb bag of Epsoak Epsom salt sold on Amazon  should last you a whole season.

How To Use Epsom Salt For Indoor Palm Trees?

Outdoor palm trees primarily grow in zones 10 to 12. But just because you live in a colder climate doesn’t mean you should miss out on the joy of having your own palm tree. I’ve dedicated a whole blog post to palm trees that are suited for zone 7.

On the bright side, you can always grow a palm tree indoors

Indoor palm trees can greatly benefit from Epsom salt, as well. 

If your parlor palm has dried or burnt leaves, you should give it a detox. Excessive fertilizing can lead to salt buildup in the potting soil, which causes root damage and those unsightly leaves. 

You can easily purify the soil with an Epsom salt rinse. Mix 1 teaspoon of Epsom salt with 1 gallon of water. 

Place your plant pot in a bathtub or a sink and slowly water it with the solution. Stop when you see it coming out of the drainage holes. Wait until the solution drains completely. 

Repeat the process 3 to 4 times before putting the palm tree back where it belongs. 

Is Epsom Salt Enough?

Using only Epsom salt on your palm trees is not enough. Palm trees require a wide range of nutrients, not only magnesium. By only using Epsom salt, you will deprive your palms of nitrogen, phosphorus, potassium, manganese, iron, and more.

The best thing to do is to use a slow-release palm fertilizer, like Miracle-Gro Shake’n Feed , as well as Epsom salt. 

Alternate the two every six weeks throughout the growing season. 

This way, you will ensure your palms are getting all the vital nutrients they need to stay healthy and pretty. 

If your palm trees are affected by potassium deficiency, you can use this Alpha Chemicals potassium sulfate  with the Epsom salt. Use both supplements at the same time. 

Lack of potassium can be detected by the browning of leaf tips. 

Other Uses For Epsom Salt In The Garden

You can extend the use of Epsom salt beyond your palm trees. A dose of magnesium will greatly benefit your other plants, as well.
