Magnesium Deficiency

Magnesium is an essential part of chlorophyll, the pigment that makes plants green and absorbs the energy of the the sun.

Identifying

Check for yellowing (chlorosis) lower older leaves with darker veins.

Solving

When planting bedding plants, vegetables, trees and shrubs add Gro-Sure Planting Magic  to the hole and soil fill. This gives the plants the best root establishment and to provide all the nutrients, organic matter and humus the plant will need for the whole season.

Did you know

Magnesium is needed to produce the chlorophyll pigment that gives leaves their green colour. When magnesium is deficient, leaves turn yellow between the veins and around the leaf edges. Other colours, such as purple, brown or red, may appear. Lower, older leaves turn first, and will die if they're not given any magnesium. Magnesium can be leached out of light, sandy, acidic soil by high rainfall. Too much potassium in the soil, may also cause deficiency as the plants absorb it instead of the magnesium.

The macro nutrients that plants need in relatively large quantities are nitrogen (N), sulphur (S), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). But plants also need trace elements in small quantities for healthy growth. Trace elements include; iron (Fe), manganese (Mn), boron (B), copper (Cu), zinc (Zn), molybdenum (Mo) and humic acids.
