If you're looking for a natural way to help your hydrangeas reach their fullest potential, then Epsom salt could be just what the doctor ordered. Not only is it a superb choice for improving soil fertility and helping your plants thrive, but it also provides essential nutrients that help combat common gardening woes.

What Epsom Salt Can do For You

Epsom salt comprises magnesium sulfate necessary for healthy plant growth. Magnesium helps in chlorophyll production, which is an essential part of photosynthesis as well as providing vital energy to the plant. On the other hand, its counterpart, sulfur, increases the production of vitamins. Both elements help strengthen cell walls and aid in overall plant development.

Beyond this, Epsom salt also plays a role in preventing magnesium deficiency in your hydrangeas. Magnesium-deficient plants often display yellowing of their leaves, rather than their gorgeous blooms. If the foliage begins to turn traditional brown color, you may be dealing with a potassium deficiency.

Not only is it beneficial for the health of your plants, but applying Epsom salt may alsohelp keep the soil moist.

What Your Hydrangea Needs

While using Epsom salt is an excellent way to care for hydrangeas, there are other methods as well. With the right techniques and a bit of know-how, you can create beautiful blooms that bring cheer to your garden.

Hydrangeas thrive in fertile, moist, well-draining soils. If the soil around your hydrangeas is too wet, it causes root rot and other fungal problems. To prevent this, make sure excess water drains away from your plants instead of pooling around them. This will also help in the absorption of Epsom salt.

If your soil is lacking in nutrition, add some compost to give it a nutrient boost. And don't forget about fertilizing. Use a balanced N-P-K time-released fertilizer a few times a year. Read the instructions on the package and apply the product according to their recommendations to avoid over-fertilizing. Be aware that Epsom salt is not a replacement for fertilizer.

Hydrangeas like shady spots, but also need at least six hours of sunlight per day to thrive and grow healthy flowers. They also require regular waterings (once per week) so they don't dry out. Epsom salt helps maintain some moisture, however, check the soil before watering. If it's already damp, there's no need to add more moisture until it has had time to completely dry out.

Applying Epsom salt to your hydrangeas is actually quite easy! First, test your soil for a magnesium deficiency. If your soil is lacking in this vital nutrient, measure out 1 tablespoon of Epsom salt in a watering can for every 9 square feet of garden space.

Make sure you are applying the right amount of Epsom salt and measure before adding it to water. Use a kitchen tool to measure out 1 tablespoon (15 grams) of Epsom salt. Doing so ensures you are not over-fertilizing and harming your plants.

Once you have the right amount, fill up your container with one gallon of water and mix thoroughly until all the salt has dissolved.

Now it's time to apply! All you need to do is sprinkle or spray the mixture directly onto the soil near your hydrangea roots every two to four weeks. Cover the entire area, as this helps ensure your plants get all the nutrients they need.

Caveats to Using Epsom Salt

When it comes to healthy plants, magnesium is an essential nutrient. Unfortunately, because of mineral imbalances in the soil and/or the type of plant, many gardeners and farmers find themselves dealing with a magnesium deficiency in their crops. Light, acidic, or sandy soils are especially prone to this issue.

Epsom salt is an easy solution for magnesium deficiencies because it's highly soluble. However, too much of a good thing may also be bad. Using excessive amounts of Epsom salt, or adding it to nondeficient soil,leads to toxic build-up in soil, and inhibits calcium uptake. This may cause blossom end rot in some crops and may also further damage your plants by leaf scorch. To avoid this, make sure you know the right dosage for your plants and soil type before using Epsom salt as a remedy.

Additionally, regular rainfall or irrigation is beneficial for your plants. But heavy watering leads to an inability for the soil and its plant inhabitants to properly retain essential minerals such as magnesium. Which means no matter how hard you try adding Epsom salts won't help.

Finally, while Epsom salt adds magnesium to the soil, excess magnesium also increases mineral contamination of water.

Blossom Better With Epsom Salt

Who knew that something as simple as adding Epsom salt to your soil could do wonders for your hydrangeas? Not only does this natural mineral help with fertility and provide protection against diseases, but it also makes them look even more beautiful! As it's easy to apply, there's no excuse not to give your hydrangeas the best chance of success possible. Therefore, if you want to ensure maximum growth and lushness from your plants, don't wait any longer -- get out there and give them the help they need.

Now that you know the important role Epsom salt plays in keeping your hydrangeas looking their best, leave a comment below on how it's worked for you. Most importantly, don't forget to share this essential gardening tip with your family and friends too.
