What Does Magnesium Do?

Magnesium has a wide range of roles in a plant. As magnesium is a building block of chlorophyll, the nutrient’s main role is to aid in the process of photosynthesis and promote healthy, green leaves.

Symptoms Of Magnesium Deficiency: 

A plant with a magnesium deficiency will often have yellowing between the veins of the leaves. The leaves will occasionally also have red/brown tints and may fall prematurely.

Control:

To rectify a magnesium deficiency, use a fertiliser containing high amounts of magnesium, such as NutriFlo Mag-Sul which contains 6.8% magnesium.

Magnesium Sulphate is also ideal as it contains 16% magnesium oxide.

Control

We recommend using a fertiliser with a high magnesium content, for example NutriFlo Mag-Sul. EpsoTop Bittersaltz is also ideal as it contains 16% magnesium oxide.
