Epsom Salts (Magnesium Sulfate)

Learn the Benefits for Rose Plants

Epsom Salts

Epsom Salts , or Magnesium Sulfate is one of the primary micronutrients for roses and other plants.

 Hydrated Magnesium Sulfate  Fertilizer (Magnesium and Sulfur) is very important in growing healthy plants.

Roses in particular require high levels of magnesium, so at 9.8% Magnesium and 6% Sulfur, it is (in small doses) a great combination for roses!

Common magnesium deficiency symptoms include leaves that are yellow between the veins, curling of leaves and stunted growth.

Keep in mind that if your soil is acidic, using Epsom Salt  will lower the PH even more.

It is  best to know the PH of your particular soil, and to test the soil for deficiencies.  Also please keep in mind that using to much of this can be toxic to your plants. (As with all fertilizers, organic or otherwise, more is not better!)

What are the benefits of using Epsom Salts for Plant Fertilizer?

Benefits of using it include;

  • Not only does it green up the plant by increasing chlorophyll production, but also improves flowering.
  • It enables the plant to promote more cane breaks by stimulating the feeder roots, thus enabling them to easily absorb the fertilizer.
  • Epsom Salts increase the plants ability to take in nutrients.
  • Roses are a deeper, richer color.
  • Plants are stronger and healthier and more disease resistant

How to Use This Organic Fertilizer in the Rose Garden...

Planting New Roses

Before planting a new rose bush, it is always best to soak the roots in a pail of water to allow it to become hydrated. Add 1/2 cup of Epsom to the water for added benefit.

Before planting the rose, sprinkle a Tablespoon of Epsom directly in the planting hole and cover with soil. (Make sure you cover it, so that the roots don't directly touch the Salt.)

Fertilize Monthly

For greener, bushier plants that are stronger and better at warding off diseases and pests;

You can use this organic fertilizer on your roses monthly. It is common knowledge between Organic rose gardeners to apply this in early spring to green up the plants and give them a boost.

Sprinkle one or Two Tablespoons per bush., depending on the size of the rose bush. Circle the salt around the  rose plant directly around the dripline of the bush and water it in. (Don't apply in the heat of the day when the sun is very strong!)

If Foliar Feeding is easier for you, then try this when fertilizing your rose bushes;

Mix 1 Tablespoon of Epsom Salts with one gallon of water and spray on the bushes every six weeks beginning when the bush leafs out until the end of the growing season. (Around 4 applications).

I always fertilize with this in early spring, but I am going to try using it as a foliar spray next year....I will keep you posted on my results!

I would love your comments on using this on your roses, so if you have had experience (good or bad) I want to hear from you!

Reader Comments;

Eleanor from Ireland writes; I used it for the first this year as I said in my first comment I sprinkled it around the roots but I also used it as a spray during the summer months on all my other plants. It worked like a dream and as I said I had way more flowers and enough tomatoes to feed my neighbourhood.The only thing you must remember is to do it in the evening as the plants would get burned if you do it in bright sunlight. I was delighted with the results,I will be using it from now on. Thank you for letting me join your group as my roses are my pride and joy.

Thanks for your comments Eleanor! Yes, you should not use it in the heat of the day, nor should you over do it!
