If your lemon tree isn’t producing as much fruit as you’d like, or if it’s not looking healthy, it may be because of a magnesium deficiency. Magnesium is an essential nutrient for healthy plant growth, and deficiencies are common in many parts of the United States, especially in naturally alkaline soils. Fortunately, there’s a simple fix.

Use Epsom salt to provide your lemon tree with the nutrients it needs for optimal growth since it is a natural source of magnesium sulfate. To determine whether your lemon tree needs magnesium, do a soil test first. It will provide information on the levels of essential nutrients, including magnesium. If it’s low, Epsom salt is an effective and inexpensive solution to help your fruit trees thrive.

For a flourishing citrus garden, acidic soil with a pH of 5.5 to 6.5 is ideal — and Epsom salt provides just the right amount of magnesium sulfate for optimal growing conditions!

Symptoms of Magnesium Deficiency

Magnesium deficiency can be a major problem for citrus trees, as it affects their ability to photosynthesize sunlight efficiently and thus reduces the productivity of the tree.

The primary symptoms of magnesium deficiencies are yellowing of the foliage. It presents itself along the tips and edges of older leaves. If you suspect your lemon tree may have a magnesium deficiency, using Epsom salt will help restore your tree’s health.

The first step is testing your soil. You can use a homemade tester or buy one from your local garden center

Once you are sure the soil lacks crucial nutrients, you can take appropriate steps to complete them. Start by completely dissolving 1 to 4 ounces of Epsom salt for every cubic foot in water, stirring until all the granules are gone. This can be applied in two or three doses per season. 

It will create a solution that you can pour over soil above the root area of your lemon tree. However, do not pour it directly on the roots. Make a mound around the root zone, about a foot in diameter, and pour the solution around the mound.

Alternatively, spray your lemon tree leaves with the Epsom salt solution, only once or twice per year.

Monitor for Changes

As with any gardening treatment, you’ll want to monitor your lemon tree after application and observe how it responds. After a few months, you should see signs of improved magnesium content in its foliage and a healthier lemon tree overall!

If, however, your lemon tree continues to show signs of yellowing, or general unhealth, consider other factors. Such as watering frequency, disease, or temperature conditions.

While Epsom salt can help ease magnesium deficiency, you should not overuse it, as this can cause other nutrient imbalances in the soil. Additionally, use Epsom salt for treating deficiency-related issues and do not replace it with regular fertilizing for healthy growth.

Epsom salt and water solutions are often used to fertilize citrus trees, but use caution when applying these mixtures. Though spraying foliage with Epsom salt and water can be beneficial for a lemon tree, it can also cause damage to the leaves when used excessively.

To avoid this issue, dilute the mixture before spraying and never exceed the recommended concentrations. Furthermore, using a horticultural wetting agent helps dissolve the water solution more evenly over the leaves and can reduce potential leaf scorching.

Magnesium in Epsom salts seeps quickly from the soil. Frequent applications may be necessary to get the desired results. However, excessive magnesium leaching could end up polluting water tables or other environmentally sensitive areas.
