Gardening with Epsom Salt

Hello all, today we are gardening with Epsom salt.  Epsom Salt (or magnesium sulfate) is an inorganic mineral compound that has many, many uses.  It can be used as a soak, an exfoliate, and is used in many home remedies. However, there is more to Epsom salt than meets the eye as it has uses in gardening as well!

Rose Gardening

Everyone knows that I love roses, so it really should be no surprise that roses are the top of this list.  Epsom salt in general helps plants grow, but for roses it really helps to boost the magnesium levels in their leaves.   This helps produce fuller blooms, more striking color, and stronger plants in general.

When you soak your roses prior to plant, try soaking the roots in a mix of half a cup of Epsom salt and a gallon of water.  During the growing season, you can sprinkle some Epsom salt around the  base of the plant and then use carefully use your water hose to help dissolve it into the soil.


However, roses aren’t the only flowers to benefit from Epsom slat.  There are many others such as tomatoes and peppers that benefit from it’s application.  Plants like roses, tomatoes and peppers can be somewhat prone to magnesium deficiency.  Studies have shown that 4 out of 6 gardeners have noticed that their peppers treated with Epsom Salt were larger than untreated.  

Many commercial fertilizers add magnesium to help plants absorb important nutrients in the soil.  For those who prefer a more natural approach to gardening, this can help tremendously.  By using a little Epsom salt in your watering, or as a fertilizer, you also help to promote greener foliage.  This helps to keep browning and withering at bay.  By applying some Epsom salt, about every month or two, you can really help to green up your plants!

Pest and Weed Control

Epsom salt can be used in many instances to help control some pests and weeds.  It’s no secret that slugs and salts do not mix.  Just sprinkle out some Epsom salt where your slugs frequent, and prepare to kiss those slugs good bye!  (Hopefully, not literally.) There’s even been a study from the University of Nevada Cooperative Extension that claims that bowl of Epsom Salt can kill roaches.  The salts upset the roach’s natural biological processes and prevents their feeding.  Eventually, the little buggers die.  Granted roaches aren’t a pest that feed on plants, but it can help demonstrate why Epsom salts tend to work against beetles and other pests.

As far as weeds are concerned, mix 2 cups of Epsom salt with 1 gallon of vinegar with a little dish soap, then you have an inexpensive weed killer.  Just spray your weeds, but be careful not to get any on your plants.  

Wrap Up

As you can see, there are many benefits to gardening with epsom salt.  At the very least it helps some plants avoid a deficiency.  In others, it helps to strengthen the plant and repel nasty critters.  Have you ever tried using epsom salts in your garden?  How did it turn out, and do you have any advice?
