Epsom salt is not a new idea in gardening. Is this “best-kept secret” actually effective, and if so, how does it work? For many of us, this issue has arisen at some point in our lives: “Why put Epsom salts on plants?”
Is Epsom Salt Good for Plants?
Yes, it appears that Epsom salts can be beneficial to plants. The green hue of plants is enhanced by the use of Epsom salts, which aid in flower blooming.
Plants can even benefit from it, as it encourages them to become denser. When it comes to planting health, magnesium sulphate (hydrogenated magnesium sulphate) is essential.
Why Put Epsom Salts on Plants?
What’s the harm in giving it a try? No matter how sceptical you are, it is always worth a try.
Beneficial elements like nitrogen and phosphorus are more readily absorbed by plants when magnesium is present.
For photosynthesis, chlorophyll production is also aided by this substance.
The ability of a plant to generate blooms and fruit is also considerably enhanced by magnesium.
Due to its low toxicity, you are free to use Epsom salt on practically all of your garden’s plants, even if the soil has become deficient in magnesium.
How to Water Plants with Epsom Salts
Want to learn how to use Epsom salts to water your plants? It’s a piece of cake. Every month or two, use it in place of your normal watering schedule.
Go with what works best for your situation, and don’t be afraid to experiment.
It’s a good idea to have your soil tested for magnesium deficiency before applying Epsom salt. Be aware that many plants, such as beans and leafy vegetables, thrive on soils with low magnesium levels.
It is more customary to use Epsom salt in the watering of vegetables like tomatoes and peppers, which require a lot of magnesium.
Epsom salt is easily absorbed by plants when diluted with water and sprayed as a foliar spray. A solution of 2 tablespoons (30 mL) of Epsom salt per gallon of water can be used to spritz most plants once a month.
Reduce the amount to 1 tablespoon if you want to water more frequently (every other week, for example) (15 mL).
Roses can be sprayed with a foliar spray using 1 tablespoon of liquid per gallon of water for every foot of shrub height (31 cm).
As soon as the leaves begin to develop, and again after the flowers have faded.
If you’re growing tomatoes or peppers, sprinkle 1 tablespoon of Epsom salt granules or spray it on the plants before transplanting and again after the first bloom and fruit set for a total of 1 tablespoon or 30 millilitres of salt per gallon.

- Houseplants: 2 tablespoons per gallon of water; feed plants monthly.
- Roses: 1 tablespoon per foot of plant height per plant; apply every two weeks. Also, scratch 1/2 cup into the soil at the base to encourage flowering canes and healthy new basal cane growth. Soak unplanted bushes in 1 cup of Epsom Salt per gallon of water to help roots recover. Add a tablespoon of Epsom Salt to each hole at planting time.
- Shrubs (evergreens, azaleas, rhododendron): 1 tablespoon per 9 square feet. Apply over root zone every 2-4 weeks.
- Lawns: Apply 3 pounds for every 1,250 square feet with a spreader, or dilute in water and apply with a sprayer.
- Trees: Apply 2 tablespoons per 9 square feet. Apply over the root zone 3 times annually.
