Epsom salt for palm trees how much

What Is the Best Fertilizer for Palm Trees | Davey Blog

Ahhh, palm trees! That bright green pop against the clear, blue sky ignites feelings of bliss.

But the truth is, while palms may look carefree, their leaves, or fronds, may tell a different story! Most palms grow in soil that lacks essential nutrients, which is a big reason why palm fronds turn yellow.

So, what can you do to help make your palms’ existence as happy-go-lucky as they make you feel?

Read on to learn how to provide your palm the nutrients it needs with the right fertilizer!

What kind of fertilizer do you use on a palm tree?

When picking a fertilizer, you want to choose a slow-release formula made for palm and tropical trees.

A slow-release fertilizer made for palms will deliver the perfect amount of nutrients over several months' time. So, your tree will get lots of nitrogen and potassium as well as small amounts of other nutrients, like magnesium, manganese and iron.

At Davey, we made this specially-formulated fertilizer to give your palms exactly what they need!

Can you use a homemade fertilizer for palm trees?

Most homemade fertilizer mixes aren’t going to provide enough of the nutrients your tree needs.

For example, a common fertilizer recipe for palms includes cottonseed meal, dolomite lime, bone meal, kelp meal and used tea leaves.

With that mix, your tree won’t get enough iron, manganese or magnesium. Plus, if you live in the Western U.S., your soil is likely alkaline (meaning it’s high in pH). So, the calcium in the bone meal causes issues instead of solving them.

Another popular DIY palm tree fertilizer calls for beer, Epsom salt, ammonia and water. This one won't deliver enough potassium or nitrogen!

With fertilizers, you want to choose a mix that has been scientifically formulated to provide the nutrients your palm needs. A DIY blend will leave your palm craving the nutrients your mix lacks.

Is an Epsom salt fertilizer good for palm trees?

Epsom salt alone is not a good fertilizer for palms for the reasons mentioned above. And specifically, too much will cause potassium problems.

But if your palm is suffering from a magnesium deficiency, Epsom salt can be a good supplement in addition to regular fertilizer applications. If that’s the case, use Epsom salt. Sprinkle 2 to 3 pounds of Epsom salt under the tree’s canopy, then water.

When to Fertilize Palm Trees in Florida and Other States

If you live in Florida, your palms need a little extra attention because of the sandy soil and excess rain. So, fertilize your palm tree three or four times a year.

If you live in another state, two or three fertilizations are what your palm needs.

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. 

When Is Epsom Salt Good For Palm Trees?

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.  

You can watch this YouTube video to see how to correctly fertilize your palm trees:

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 Alpha Chemicals potassium sulfate with 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.  

This practical YouTube video will give you ideas on how to use Epsom salt around your lawn and garden. Check it out!

Keep It Green and Beautiful 

So, is Epsom salt good for palm trees?

Yes! When used in the right amounts, Epsom salt can be very beneficial for your palms. You can use it to treat or prevent magnesium deficiency.  

Magnesium sulfate will help keep your soil rich and your palm trees looking green and beautiful. You only have to treat them four times a year during the growing season to maintain their health. 

Here is how you do it:

  1. Buy quality Epsom salt for palm trees.
  2. Evenly distribute 2 to 4 pounds of Epsom salt over the root zone.

15 smart ways to use Epsom salts in your garden

Think you're a master gardener? If you are not already using Epsom salts in your garden, there is still a lot to learn.

There are many unique things you can use in your garden to improve the health of your plants, including coffee grounds, eggshells, and yes, even beer! However, one of the best things you can add is Epsom salts.

If you don't use Epsom salts yet, try it. There are many ways your plants can benefit from Epsom salts, many of which you may never have heard of.

Here are some of the easiest ways to incorporate this simple fix into your daily gardening routine.

Why Epsom salt?

Epsom salt, unlike regular old table salt, is loaded with minerals that help plants absorb nutrients more efficiently. They can help your plant produce fruit and contain tons of magnesium to keep you healthy.

Plants need magnesium because it helps them absorb other valuable nutrients such as phosphorus and nitrogen. It can also help your plants produce chlorophyll, which is vital for photosynthesis. Without magnesium, it can be difficult for your plants to produce fruits and flowers.

These salts are affordable and easy to find. You can find Epsom salts in most pharmacies and grocery stores, usually located in the bathroom aisle. Epsom salt, a cheap and easy soil improver, should be in every gardener's box.

Unlike other types of additives, Epsom salts do not accumulate in the soil and cause no toxic side effects.

15 Ways to Use Epsom Salts in the Garden

1. Leaf Spray

Epsom salt is often used as a spray on some plants, such as tomatoes. To make a spray that provides your plants with a healthy dose of magnesium, simply mix tablespoon of Epsom salts with a gallon of water.

You can thin as early as possible when you see new leaves starting to appear.

Use approximately one gallon of mixture for every 12 inches of plant. The best time to apply is a cloudy day or early morning.

2. Soil Amendment for Peppers, Tomatoes and Roses

Although there are very few plants for which Epsom salts cannot be used, there are all types of plants for which these additives are particularly beneficial. Tomatoes, peppers and roses are the three most common.

To use Epsom Salt on these acid-loving plants, you need to improve the soil before planting with a quarter cup of Epsom Salt spread out every 25 square feet. All you need to do is sprinkle this salt over the soil and then mix it in at a depth of six to eight inches.

You can also add a tablespoon of Epsom salts to the bottom of the planting hole when planting any of these species. It is well suited for both cuttings and transplants.

3. Apply around landscaped trees

There are some types of trees that really benefit from adding Epsom salts, especially landscaped trees and tropical trees.

One example is a palm tree. Palm trees used for landscaping are often deficient in magnesium, which growers refer to as "curly top". This makes the tops of the leaves look tattered and frizzy, usually light green in color.

To solve this problem, simply apply Epsom salts to the base of the tree. You can also spray the leaves and crown of the tree with a mixture of one tablespoon of Epsom salts to one gallon of water.

4. Use Epsom salts on the lawn.

For lawns that look a bit shabby, Epsom salts can also save the day. To apply them to your lawn, you need to fill a spreader with about three pounds of Epsom salts.

It does not need to be diluted. Use a spreader to spread the salt evenly over the lawn about times a year . Seven pounds will give you enough salt to cover every 2500 feet or so.

5. Fertilizing potted plants.

Any potted plant, whether indoor or outdoor, can benefit from a dose of Epsom salts. You need to mix two tablespoons of Epsom salts with a gallon of water. Simply apply enough solution to thoroughly moisten the soil and reapply once a month.

6. Leaching fertilizer salts

Sometimes houseplants can become oversaturated with fertilizer residues. Most often, toxic fertilizer salts can remain in the soil.

You can leach these salts, although it sounds counterintuitive, with Epsom salts. Just dilute a teaspoon of salts in a gallon of water and pour it through the planter. As soon as the water starts to flow out from under the bottom, you can stop pouring fresh water.

7. Use Epsom salts on the bushes.

There are shrubs that also love Epsom salts. Acid-loving shrubs like azaleas and rhododendrons benefit the most from these salts as they tend to need more magnesium. You will use one tablespoon for every nine square feet. Make sure you water them deeply after application.

8. Start Seeds

You can give your seeds the best start by adding a tablespoon of Epsom salts and a gallon of water to the soil when planting the seeds. You can apply this mixture at the rate of one gallon for every 100 square feet.

Make sure you thoroughly mix the mixture into the soil before watering. Magnesium promotes germination because it strengthens cell walls and provides energy for growth.

9. Use magnesium to prevent transplant shock.

Transplant shock, also known as root shock, causes symptoms such as leaf discoloration and wilting. When you transplant plants to transplant them outdoors, add a tablespoon of Epsom salts to the planting hole.

10. Keep pests away

Some pests really don't like Epsom salts. In particular, Epsom salts can be used to repel slugs and snails. To repel pests and encourage plant growth at the same time, simply mix half a cup of salt with two and a half gallons of water before spraying

11. Foliage improvement for ornamental plants

Over time, ornamental plants leach nutrients from the soil and leaves become pale and unattractive. While they may still grow normally, they don't look as pretty as you'd like.

If you have mature foliage that is curling or turning yellow, you can add a foliar spray of Epsom salts to correct a magnesium deficiency.


Improve the taste of fruits

Some fruit plants, including vines, berry bushes and fruit trees, receive a monthly Epsom salt supplement. Simply mix a tablespoon of these salts with a gallon of water and apply to plant roots. You will notice that the taste is much brighter!

13. Remove tree stumps.

Getting rid of stumps on your property can cost hundreds of dollars. However, you can use Epsom salts to do the job for you. Simply drill a few holes in the top of the stump, about half the depth of the stump itself. Space these holes a few inches apart, then pour salt into the hole. Add some water to moisten the holes.

Over time, the salts dehydrate the wood and cause it to rot. You will be able to cut pieces in just a few months.

Video demonstration of this method:

14. Use Epsom salts as a top dressing.

If you need to increase the amount of magnesium during the growing season, all you have to do is sprinkle a tablespoon of Epsom salts on the base of the plant. Water deeply - that's all!

15. Flower improvement

If your plants are having trouble blooming, you can use a little Epsom salt. Healthier and stronger plants will of course produce brighter flowers! Add a few tablespoons of Epsom salts when planting, then use it as a foliar spray when watering once every two weeks.

General Epsom Salt Tips

Epsom Salt is most easily absorbed by your plants when you dilute them with water.

Before adding Epsom salts to plants, it is wise to do a basic soil test.

This will help you confirm if your soil is truly magnesium deficient. Without soil analysis, you can determine if your plants are deficient in magnesium by looking at their color and growth. Usually stunted, curled or yellowing leaves indicate a lack of magnesium.

You should avoid using Epsom salts as a major nutrient in your garden.
