Epsom Salt holds magnesium and sulphur. They belong to secondary nutrients that plants truly need in quite big amounts, especially together with calcium. The chemical name of Epsom Salt is sulphate of magnesium.
Although it calls itself salt, Epsom Salt is not like the salt that one puts on chips. One calls it salt because of its chemical structure.
How to Use Epsom Salt on Fig Trees
Fig Trees need a lot of magnesium in the ground. The best way to give that is by means of a solution of Epsom Salt that one pours directly to the roots, so that the tree absorbs everything needed. Magnesium forms key food for plants and Epsom Salt indeed appears among the ingredients of water-based dressings, mixed in water together with various other elements.
Even so, magnesium will be useful to Fig Trees only if they truly lack it. When no sign of absence shows, no need exists to add it. Careful use of Epsom Salt is good strategy.
Usually one dissolves one spoon of Epsom Salt in a gallon of water and uses it monthly. For big mature Fig Trees, an amount between one-quarter and one-half spoon per gallon of water works well, while the other plant foods stay available at the same time.
Small cuttings start with smaller doses, later one moves to one spoon per gallon of water, including a quarter spoon of Epsom Salt, while they grow and feed in a one-gallon jar. Some growers mix Epsom Salt in dry soil mixes. For instance, add four pounds of Epsom Salt too twenty-five pounds of 16-16-16 dressing, together with minor nutrients, to create a reliable dry mix.
Epsom Salt can also go in organic change of soil. One recipe holds manure, bone food, blood food, potash, food of kelp, two tablespoons of Epsom Salt, minerals, fungus helpers, limestone and acid. One mixes everything with potting soil and worm castings.
If Fig Trees seem a bit pale or have yellow leaves, Epsom Salt helps. Clear improvement commonly happens quite soon after usage. It delivers magnesium and sulphur there, where the tree needs them.
Even so, never add Epsom Salt unless there is real absence. A test of soil helps to check, whether adding it makessense.
Epsom Salt from pharmacies, that has 100% USP-grade and food grade, does not hold extras. It usually costs under one dollar per pound, with tax included. Commercial grade of sulphate of magnesium forms an even cheaper option for big purchases, where one must ask for proof of analysis to confirm, that it reaches around 99.95% purity.
Beyond the garden, Epsom Salt works as an addition to bath water to cool painful muscles. Although the idea of absorbing magnesium through the skin is very popular, few official studies appeared about that. Simply bathing in warm water alone eases pain for many reasons.
