There are many ways to prevent magnesium deficiency in plants, but the most effective way is to add magnesium sulfate or Epsom salts directly to the soil. These minerals dissolve quickly and help ensure that plants have enough Magnesium.
Use a magnesium leaf spray, such as Epsom salts, on potatoes for a quick, temporary solution in summer. Apply Epsom salts or calcium-magnesium carbonate to the soil in autumn or winter to remedy the deficiency for next year.

If you're looking for a fertilizer that's rich in magnesium, you've found it.
Epsom salts can be a good source of magnesium, but only use them if a soil test indicates that you have a magnesium deficiency. Magnesium deficiencies in the home garden in Minnesota are most likely to occur on sandy, low pH soils.
Add Epsom Salt to the Garden Beds
Some gardeners find that Epsom salt works well to add magnesium. Using Epsom salt seems to help plants absorb their nutrients easier while also solving the deficiency in the soil. The nice thing about using Epsom salt is it increases magnesium without altering your pH range.
Prep garden soil by sprinkling up to one cup of Ultra Epsom Salt per 100 square feet, and then work it into the soil before seeding or planting. This helps the seeds to germinate and start with a strong, healthy growth.
The easier, healthier approach is to add compost or plant residues to the soil surface or to incorporate them into only the top few inches of soil. The soil biota will take care of breaking the material down into nutrients your plants can use, and moving the nutrients down into the soil where plant roots can find them.
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose ...
The three natural methods of adding nutrients to soil are: Field fallow. Crop rotation. Mixed cropping.
In some areas, regular use of magnesian limestone over many years has increased soil magnesium. However, in other areas, high soil magnesium is naturally occurring due to the parent material. In general, high soil magnesium concentrations do not damage crop growth, but may hinder the uptake of potassium.
A little extra magnesium is not particularly harmful. When growing in soil, excessive quantities of magnesium do not appear quickly. Too much magnesium inhibits the uptake of calcium, and the plant displays general symptoms of an excess of salts; stunted growth, and dark-coloured vegetation.
Fertilizers such as dolomite and hydrate dolomite are commonly used to supply magnesium and raise soil pH. Other mineral sources include lainite, langbeinite, kieserite, schoenite, and struvite-chemical sources magnesium chloride, magnesium oxide, and magnesium sulfate.
The first signs of magnesium deficiency appear on the older lower leaves as magnesium moves towards new growth. As the deficiency develops, chlorosis can move to the younger leaves as well. Eventually as chlorophyll reduces, some plants may display red, purple or brown tints.
Using water without calcium causes a magnesium deficiency in plants but can be corrected by supplementation with regular nutrients including magnesium and calcium. Once you have handled the issue, watch the plants closely for signs of deficiency recovery.
If your magnesium is low because you aren't getting enough magnesium in your diet, try to eat more of the following foods that have lots of magnesium: Nuts and nut butters — especially almonds, peanuts, and cashews. Spinach. Grains, like rice and whole-wheat breads and cereals.
We may sum up the matter briefly thus: To build up and maintain fertility in the soil, feed a large part of the crops and return the manure to the land. If manure is not available, plow under crops grown for the purpose. Plow deep (but do not subsoil). Grow leguminous crops for the nitrogen they add to the soil.
Adding organic amendments like composts and manures to soils supports and feeds soil microbes, enabling them to do their work of making nutrients available to plant roots. Vegetable gardeners often need to amend their soil each year, adding back the nutrients that were depleted during the previous growing season.
Banana peels can be placed directly onto pot plant soil, or around the base of your garden as mulch. As they decompose, they will release nutrients into the soil to feed plants. If using banana peels in your garden, place a single layer straight on top of the soil, being sure not to let them touch the plant stem.
Organic matter comes in many forms, from home-made compost to well-rotted manure (horse and pig and pelleted chicken manure are popular for feeding garden soils). You can also grow green manures, which you sow on bare patches of earth and then dig into the soil before they flower.
Insect-eating plants such as Pitcher plants, sundews and Venus flytraps are other plants that do not like Epsom salt. They've adapted to growing in poor soils and even a little can kill them.
Prevent Fungal Disease
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
If you add it to your soil properly, Epsom salt can help your garden plants thrive because it increases levels of magnesium, one of the vital nutrients in garden soil.
