Will Epsom Salts Help a Lemon Tree to Bloom?

Answer

For optimal growth and development, lemon trees, also known as Citrus limon, need a diverse array of nutrients in the soil. The tree does well in plant hardiness zones 9 through 11 according to the United States Department of Agriculture. Epsom salt, also known as magnesium sulphate, is a mineral that may be used as a fertiliser. It is a source of organic magnesium and sulphur. Epsom salt supplements may be beneficial to the health of lemon trees, particularly if the soil in which they are grown has been heavily farmed or does not contain sufficient magnesium. Before you start using Epsom salts, you should be sure that there are no other probable reasons of low bloom production and that a magnesium deficit is present in your soil.

Soil

The vitality of citrus trees may be hindered by a number of factors, including improper cultivation, pests that are damaging, and illnesses. Conduct an analysis of the soil to verify your suspicions about a lack of magnesium as the underlying reason of poor performance. In alkaline soils and the northern Pacific areas of the United States, magnesium shortage is rather frequent. Utilize a comprehensive commercial kit that may be purchased from a local garden shop or testing service in your region. If you want in-depth advice on the amendments and fertilisers that are indicated for lemon trees, you should choose a test that lets you name that crop specifically as the one in issue.

Citrus Nutrients

For optimal growth and development, in addition to the primary plant nutrients nitrogen, phosphorus, and potassium, citrus trees need adequate levels of sulphur, calcium, and moderate amounts of a wide variety of secondary minerals, including magnesium. A general yellowing of the foliage of citrus trees throughout the growth season is one sign that may particularly imply that there is a magnesium deficit in the soil. Typically, this begins at the tips and edges of older leaves and extends inside, leaving an arrowhead shape of green tissue flanked by yellow borders. Because affected leaves are unable to photosynthesize properly, your lemon tree’s yield will suffer as a result.

Using Epsom Salts

Epsom salts may be used as a remedial treatment if it has been established that a magnesium deficit is the cause of the issues impacting your lemon tree. You need to make sure that the salts are thoroughly dissolved in the water. After that, you may either spray this solution over the lemon tree’s leaves during the active growth season or pour this solution over the soil that is located above the root zone of the lemon tree.

Precautions

It is possible to scorch leaves by spraying vegetation with solutions including Epsom salt and water. To help prevent this, you should use a horticultural wetting agent. Wetting agents are a kind of surfactant that assists in the distribution of water solutions more uniformly over surfaces. Epsom salts include a type of magnesium that is easily dispersed via soil. It has a small window of effectiveness and has a high potential for rapid loss. This appears to imply that regular applications of epsom salts are required to remedy the problem. However, if there is an excessive amount of magnesium in the soil, it may become a contaminant if it leaches into water tables or other ecologically sensitive places.
