Hostas continue to be one of the most popular perennials in shady and party shady gardens. It's no wonder. Hostas are easy to grow and care for, they don't require a lot of special attention and they come in a vast array of sizes, shapes, and great leaf colors.
Since the real beauty of hostas lies in those gorgeous colorful leaves, it is only natural to seek out an organic soil amendment that will enhance leaf color and help the plant grow bushier and healthier. That's where Epsom Salt comes in.
The idea of using Epsom Salt in the garden is not a new concept. It's been around for generations because it works.
So what are the advantages of using Epsom Salt in your hosta garden?
Well, the main ingredient in Epsom Salt is magnesium sulfate which is an important soil additive for healthy plant life. It allows plants to take in nutrients like phosphorus and nitrogen and assists in the creation of chlorophyll which is used by the plant to convert sunlight into food.
The benefits of Epsom Salt on plants are many including that it’s organic, it’s gentle on plants and it’s inexpensive!
Here are some specific ways Epsom Salt helps with plants in general.
- Improves flower blooming.
- Enhances a plant’s green color.
- Helps plants grow bushier.
- Greatly improves a plant’s ability to produce fruit and flowers.
- Assists in seed germination and gives a stronger start to seedlings.
- It’s safe, and there is little danger of problems from overuse.
- It doesn’t build up in the soil and it won't have buildup that will clog the root cells of your plants. In fact, Epsom salt can be used for potted plants that have developed a salt accumulation.
Another big advantage of Epsom Salt is its versatility in the way it can be used. You can sprinkle Epsom Salt over a large garden area, you can use it to circle around plants or you can add a solution of Epsom Salt to a garden sprayer. Click on "garden sprayer" right below. This is the one I use. It's a half-gallon, it's easy to hold and sprays beautifully.
How to Use Epsom Salt on Hostas
- For potted hostas, mix two tablespoons of Epsom Salt in one gallon of water. Water the potted hostas once a month with this mixture.
- With the same solution, you can use a sprayer to spray the mixture directly on the leaves to keep them lush and healthy,
- A few tablespoons of Epsom Salt around your ground hostas in the spring will give them a great early boost.

On a New Hosta Garden Area
If you're starting a brand new hosta bed, sprinkle up to one cup per 100 square feet and work it into the soil.
To Help with Transplant Shock
Did you know that using Epsom Salt can reduce transplant shock? Plants can become weak and wither right after transplanting, and Epsom Salt can help reduce that transplant shock to the plant roots. The solution to use for this is one cup of Epsom Salt per 100 square feet.
Hostas are known for their ease of care, but they do face one problem: Slugs! Damage from slugs appears as multiple holes chewed through the hosta leaves. The most damage will be done to varieties with thinner leaves or hostas that are variegated.
To fight this problem, apply a narrow band of Epsom Salt in a circle around the hosta. Since Epsom Salt is a scratchy substance, it will pierce the skin of any slimy creature when it crosses over it.
Epsom Salt is also effective for combating beetles and other garden pests. A solution of one cup of Epsom Salt per five gallons of water is a great deterrent to them.
Add the use of Epsom Salt to your hosta care regimen this season. Your hostas will thank you for their continued beauty and health!
