You must have heard about the uses of Epsom salts for plants, which has been practiced since ancient times. A few of these uses are mentioned here.
Epsom salts are rich in sulfates and magnesium. These are some of the most important elements for growth and development of plants. They also play an important role in stimulating the action of the regularly used plant foods provided for growth of the plant.
This salt is chemically known as hydrated magnesium sulfate, and it helps to protect as well as nourish the plants in our gardens. It is beneficial for various flowering and fruiting plants, like roses and tomatoes.

Uses in Gardening

It is known that the uses of Epsom salts for plants are many. They help to protect the plants from various diseases that lead to yellowing and discoloring of leaves. The salts carry out protective functions as the two elements, magnesium and sulfate, are very important for plant development.
They are often responsible for strengthening cell walls, effective seed germination, formation of fruits and seeds, photosynthesis, and helping the plant in absorbing required nutrients.
The major component of Epsom salt is sulfur, which includes about 13% of its composition. It is required for the internal functioning of the plants. But, there is enough sulfur present in the soil, and thus the plants are never deprived of it.
The other component of Epsom salt crystals, magnesium, holds 10% of the contents and is usually scarce in the soil. When there is a deficiency of this mineral in the plants, they show abnormalities like stunted growth, necrosis, and loss of taste in fruits.
Therefore, with so many benefits of these salts, they are surely a good choice to be included as fertilizers in your garden.

Tomato plants have a huge requirement of magnesium late in their fruiting seasons. They need magnesium as the leaves start yellowing otherwise, and the fruit production may reduce. When plants show such symptoms, they are often diagnosed with magnesium deficiency, which is then provided externally. Epsom salts can be used for tomatoes as explained further.
  • Mix 1 tablespoon of Epsom salt in the soil while planting the tomato plant, or mix the same amount in a gallon of water while watering the seedlings.
  • You can repeat this measurement of Epsom salt and water when the plants start flowering or when the fruits are juvenile. This is because the plants require more magnesium in basic phases of development.

Epsom Salts for Roses

The number of blooms produced also increases when the plants are provided with a good amount of magnesium whenever needed. Thus, Epsom salts can be used for roses as explained further.
