Why Epsom Salt and What it Does?

The compound name of Epsom salt is Magnesium Sulfate. You already get a general idea from this name that this salt is rich in magnesium and sulfur. Absence or scarcity of these compounds from the soil makes the plant lose its vigor, affect its growth, and harvest.

The magnesium-rich soil is known to give higher yields, bushier, and greener plants compared to the soil that is low in magnesium content.

Note: Just because Epsom salt is beneficial for plants, don’t apply it on every plant unless magnesium is deficient in the soil. Only some plants such as tomatoes, peppers, hostas, roses, and cucumbers benefit from the extra boost of magnesium because of their requirements.

Epsom Salt For Cucumbers

Belonging to the gourd family, cucumber is a vining plant that bears fruits we call cucumber. The high water content of cucumbers makes it perfect to beat the heat in summers, and its crunchiness makes it an excellent addition to salads.

The cucumbers grow in the warm weather, but as days pass, it loses its vigor and looks weathered down. Not only that but the plant starts to produce less and fewer fruits. Epsom salt gives this vegetable plant a boost that rejuvenates them. The trick is to apply it at least once in the mid-season and not weekly.

When to Apply

Deficiency of magnesium results in decreased yield, and also plants become more susceptible to diseases. You’ll also see younger leaves turning yellow due to sulfur deficiency. Other symptoms you should look for are slow growth and smaller than usual or late maturing fruits.

1. Watering

To apply it, take one Gallon of water in a container and add a tablespoon of Epsom salt in it. Use a spatula to stir the solution until the salt dissolves completely. Replace that day’s watering by this solution and thoroughly feed your plant with it. You could wait for 3-4 weeks before reapplying if the deficiency symptoms are not subsiding.

2. Foliar Spray

You’ll need to spray the foliage of the plant, which makes the plants absorb nutrients through their leaves rather than roots. This method is highly considered for boosting plant growth but do not think it a substitute for watering as it’s effective only in case of nutrient deficiencies.
