Using Sulfato de Magnésio (Epsom Salts) in the Garden

In my quest to use as many natural products in the garden as possible I consulted Google and found this imformative article by Backyard Boss who kindly gave me permission to repost some of the article here.

 

WHAT ARE EPSOM SALTS?

To begin, I should probably explain what Epsom salts are. Epsom salts are actually a mineral compound of magnesium and sulfate- essential nutrients that regulate enzymes and are found naturally in most living things. Originally found in Epsom, England (hence the name), they are mined from the ground and have a variety of different uses ranging from healthy lifestyle choices, help with magnesium deficiencies, crafting projects, and in our case – gardening.

Epsom salts are not salts at all even though they look like it (it doesn’t have any sodium chloride in it’s makeup). Because of this, it can be used as a natural alternative in many agricultural and health practices without ill effects- since too much true salt is actually harmful to plants.

WHAT ARE THE BENEFITS OF EPSOM SALTS FOR PLANTS?

Magnesium sulfate is actually a key ingredient for vegetation and is found naturally in soils, although they can eventually be depleted and leach over time. The use of Epsom salts in varied ways can help give a very inexpensive boost to your plants and flowers year round – whether they are grown as indoor plants or out.

Essentially they are a building block of new growth, and is supportive of overall plant health; they can be used in a variety of ways to enhance seed germination, flower production, new growth, and can aide with chlorophyll creation: which is needed for photosynthesis in all green plants.

Why Are My Kumquat Leaves Yellow?

After making some Kumquat marmalade which was absolutely delicious, I decided to grow my own Kumquat tree.

Kumquats are expensive here in Portugal so planting my own tree seemed the logical step says she, who kills most things including fig trees which are meant to be indestructible.

Fingers firmly crossed I planted a healthy tree in April 2016.

Fast forward four months and the kumquat leaves are yellow but apart from that the tree seems healthy with no leaf fall. At first, I thought it was under-watering, no. Then over-watering, negative.

I trawled the internet and the problem appears to be a nutrient deficiency

According to Best Plants

Yellow and dull looking leaves often means the plant is lacking the necessary nutrients magnesium or sulfur. Apply Epsom salt (magnesium sulfate), adding it to fertilizer placed in the soil once per month. For more direct approach, 1 tablespoon can be mixed with a gallon of water and sprayed directly onto the leaves. Be patient as different plants respond faster than others to applications.

This is an excellent website with lots of useful tips.

I then studied various other sites and yellowing of leaves could mean the roots are too wet or too dry, low temperatures, or lack of feeding. I can rule out low temperatures because some days the temperatures have been in the high twenties to mid thirties. Too much water/not enough? It receives no more than my strawberry tubs because it is on the same watering system.

Further investigation reveals it is probably Chlorosis which is used to describe the symptoms of uniform yellowing of leaves.

Green chlorophyll requires iron and manganese. Lack of these nutrients result in the yellowing between the leaf veins

So what’s the cure?

According to the Garden of Eaden blog (I won’t include a link to their website as I was bombarded with annoying popups) chlorosis is treated by

spraying leaves with soluble iron foliar feeds every 2 – 4 weeks or by lowering the soil pH.

Or by applying nutrients to the soil surface. Suggested: soluble, acidic plant fertilizers such as Miracid or Sequestration as a weekly liquid feed. As I have neither of the above in store cupboard I am going to try Epsom salts. It’s got to worth a try, yes?

Dosage: Dissolve 2 teaspoons of Epsom Salts to 1 litre of water and apply every fourteen days.

The experiment started today. I sprayed the leaves and watered the plant with the remainder.

All suggestions,tips and advice welcome!
