Ingredient Spotlight: Magnesium

Healthy plant development is hinged on many factors and one of them is a balanced supply of Magnesium.

Magnesium (Mg) has been called the ‘lamp of life’ for it’s ability to help convert sunlight into energy in a complex process we call, photosynthesis. At the very heart of chlorophyll, [actually the central atom within the chlorophyll molecule] rests magnesium; without it, photosynthesis cannot take place. Magnesium is basically the engine behind photosynthesis and if you think about it, owe our very existence to this mineral.

“Magnesium is a constituent of chlorophyll, the pigment that gives plants their green color. Chlorophyll absorbs energy from sunlight, which the plant uses to manufacture food in the process of photosynthesis. Plants lacking magnesium have a reduced ability to manufacture chlorophyll, and this has a direct impact on the plant’s ability to manufacture its own food. A lack of magnesium therefore slows plant growth. Magnesium is also used within the plant in various metabolic functions” – C. Edwards, Royal Botanic Gardens, London.

Without sufficient amounts of magnesium, plants begin to degrade the chlorophyll in the old leaves. This causes the main symptom of magnesium deficiency, chlorosis, or yellowing between leaf veins, which stay green, giving the leaves a marbled appearance. Due to magnesium’s mobile nature, the plant will first break down chlorophyll in older leaves and transport the Mg to younger leaves. Therefore, the first sign of magnesium deficiency is the chlorosis of old leaves which progresses to the young leaves as the deficiency continues. -Wikipedia

At Tappin’ Roots, we know the uptake and migration of phosphorus throughout the plant is another important function of this mineral. Since phosphorus is paramount to the development of flowers, a lack of magnesium will disrupt normal functions and plants will fail to produce sufficient flowers.
