How Much Epsom Salt to Water for Plants

Epsom salt, also known as magnesium sulfate, can be beneficial for plants when used properly. Adding Epsom salt to the soil or water is said to increase seed germination, promote growth, and help plants produce more flowers and fruit. However, it's important to know how much Epsom salt to use for each plant to avoid over-fertilizing and causing harm.

Factors to Consider

The amount of Epsom salt you should use for your plants depends on several factors, including the type of plant, the type of soil, and the growing conditions. Plants that prefer alkaline soil may require more Epsom salt than those that prefer acidic soil. Additionally, plants that are growing in sandy soil may need more Epsom salt than those growing in rich, loamy soil.

General Guidelines

As a general guideline, you can use one tablespoon of Epsom salt per gallon of water for most plants. If your plants are already healthy and growing well, you may not need to use Epsom salt at all. However, if your plants are struggling, adding Epsom salt can help to provide the nutrients they need to thrive.

Specific Plants

Some plants have specific Epsom salt requirements. For example, tomato plants benefit from Epsom salt when they are setting fruit. You can apply one tablespoon of Epsom salt per foot of plant height around the base of the plant, and then water it in well. Roses can also benefit from Epsom salt. Apply one tablespoon of Epsom salt per foot of plant height around the base of the plant, and then water it in well.

Epsom Salt Foliar Spray

In addition to adding Epsom salt to soil, you can also use it as a foliar spray by mixing one tablespoon of Epsom salt with one gallon of water. Use a spray bottle to apply the solution to the leaves of your plants. Epsom salt foliar spray is said to help improve nutrient uptake in plants and increase chlorophyll production.

The Bottom Line

When it comes to using Epsom salt for plants, less is often more. It's important to use the right amount for each plant, and avoid over-fertilizing. Remember to always follow the instructions on the package, and to consult with a gardening expert if you are unsure about how much Epsom salt to use on your plants.
