How does Epsom salt help the health of your plants?

Magnesium and sulfate are both critical in successful growing. Magnesium is important for all living things from humans to plant life, and a low amount in the soil can mean weak, poor fruit and flowers as well as a low nutritional value. Sulfate is vital for the nutritional absorption and also flushes toxins from organisms. A helpful tip in almost any garden is to enrich your plants with magnesium and sulfate by using Epsom salts.

A solution made of dissolved Epsom salt and water can invigorate your plants by providing them with an extra dose of these critical nutrients. Simply dissolve and pour into the base of the plant, letting the mixture soak into the soil. You can also use a bit of this solution to ready the soil before planting. You can use this mixture to invigorate a variety of plant life from your vegetable garden to your landscape. By diluting and dissolving in water, you make the minerals in these salts more accessible to your plants. Common effects of this natural “fertilizer” are stronger blooms and better flowering.

What specific plants do Epsom salts improve?

This practice can be especially useful when planting tomatoes which need a lot of magnesium. When tomatoes lack this in their soil, the fruits will end up not as sweet and not as healthy.


also need magnesium to grow large and to produce greater quantities.

A boost of magnesium in the soil can also help your fruit trees produce stronger and more delicious results. Adding just a little bit around the roots can even make the fruit itself more nutritious. Apply about 3 times a year to see and taste improvement.

Magnesium is an important player here, but so are the sulfur, nitrogen, and phosphorus levels that Epsom salts will increase.

    Can I just sprinkle it in the garden?

  4. Can you explain how it’s used to deter slugs please.

    • The slug contains a lot of water, which is essential for its survival. Sprinkling with salt draws that water out, and the poor creature dies of dehydration.

  5. does it have much benefit for hydrangeas?

  6. Will it help with indoor plants such as ivy

  7. could you please clarify “gallon”? Is it a US gallon or an Imperial gallon? They’re different sizes. A conversion to litre would also be appreciated for those who don’t like in the USA.

    • Oops!! I mean live in the USA

      • We have a water softener so we arent able to water the garden with the hose,(the salt system just kills the plants) so we collect rain water in barrels and just add the Epsom salt directly into the barrels,give it a stir to make sure it all dissolves then we are ready to water! It works out great and the garden has never produced so well.As per the slugs, we have ALOT,can I just sprinkle epsom salts in the flower gardens where i see them the most? will this deter them?Tried beer in the empty tuna cans and it just does not seem to work.
