However, there are many positive impacts of Epsom salt (magnesium sulfate), but its excessive use must be avoided.

1. To get sweeter fruits

Apply Epsom salt 1 tablespoon per sq ft of fruit trees and shrubs to boost chlorophyll levels inside plant cells, which means improved photosynthesis, stronger growth of the plant, sweeter fruits, and increase productivity. Fruit trees like citrus, apples, peaches, pomegranate, and plums perk up after application of Epsom salt.

2. To help plants absorb more nutrients

If you use Epsom salt as fertilizer, your plants will receive all of the required nutrients adequately. Why? The Epsom salt contains magnesium, a mineral that enhances the absorption of basic nutrients needed by plants to grow, such as nitrogen, phosphorus, and sulfur.

3. To avoid transplanting shock

Help plants to overcome transplant shocks when you plant them into a garden or change their pots, add a tablespoon of Epsom salt to the soil, then once again add a layer of soil before placing the plant so that root does not come in direct contact with the salt.

4. To have juiciest tomatoes and healthy tomato plants

7. To increase the production of peppers

Give a boost to your pepper plants by adding 1 tablespoon of Epsom salt every week, especially at the time of flowering and fruiting to increase the production of peppers.

Adding Epsom salt helps in the production of chlorophyll, which favors the bushier growth of the roses. Also, its addition encourages more blooms. Feed rose bushes with Epsom salt at the time of planting and again at the first sign of new growth. Application of Epsom salt when the plant is flowering is also helpful. You can also soak bare root roses in water that contains dissolved Epsom salt before planting.
