A pepper’s best friend

epsom salt

For a minute there, I was worried.

My beautiful pepper seedlings, which I had raised from itty-bitty seeds, were not looking so hot. The leaves were a light green, with a slight tinge of yellow. They weren’t pretty. They also weren’t really growing.

We eat a lot of peppers, especially jalapeno, so I was counting on getting a pretty decent yield of these thick-walled fruits. I have planted 32 feet of peppers, in two, 16-foot raised row beds. The varieties planted are California Wonder, Jalapeno, Pepperoncini and Sweet Chocolate.

I did a little reading online via Pinterest and made a few quick amendments and my peppers are looking good once again. The majority now have lush, green leaves and are starting to get a little taller.

Here is what I learned.

Epsom salt is a pepper’s (and tomato’s) best friend.

Early in the season this mineral compound aids in germination, early root and cell development, photosynthesis, plant growth and prevents blossom-end rot. Epsom salt, or magnesium sulfate, adds, you guessed it, magnesium to the soil. Plants like peppers and tomatoes are prone to magnesium deficiency which causes the fruit to be slow to mature and ripen. Because our season is limited, slowing the season is not a good idea. 

How to garden with Epsom salt.

At planting: This step I obviously missed, but apparently adding one or two tablespoons to the hole before transplanting peppers and tomatoes.

Throughout the season: Work in one tablespoon of Epsom salt per foot of plant height around the base of each plant. Do this two times a week. Epsom salt can also be applied as a topical spray by combining one tablespoon of Epsom salt per gallon of water in a sprayer tank (I use a $3 one from Dollarama). Apply this spray once the plants start blossoming to increase yields and keep plants lush and bushy. It is advised to substitute this application as a substitute for a normal watering once a month.

Hopefully, with if I keep up this routine, I will have a lot of peppers to eat and preserve later this season. I also plan to add a layer of black mulch to keep in moisture. I added a layer of grass mulch around my tomato and broccoli plants, however peppers do not like the extra nitrogen so off to the garden centre it is.

  1. Very interesting, I am going to give this a try with my peppers for sure this year.. I will do a trial on them, do it with some and not others and compare..

    Saving this post in my favorites, thanks for sharing it on the green thumb link up!

  2. Thanks for the tips about growing peppers! My peppers always need some help!

    Thanks for linking up with Green Thumb Thursday. I hope to see you again this week!

  3. We use epsom salt on tomatoes, peppers and other plants also… and it does make a big difference. Last year, the grass looked light green, so I had the guys use it on the lawn too… and within a day, the green color was much richer looking and intense. 🙂

  4. Great advice, and I’m going to have to start doing this as my pepper plant’s are not doing too good. Although, it might be because my tomato plants have decided to grow like crazy and are overshadowing the peppers…. either way I’ll be giving this a try. Worst case scenario, the tomatoes produce even more…
    Thanks for sharing.
