Magnesium Deficiency

Garden Problems , Garden Products , Houseplant Products

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

Identify the problem
Check for yellowing (chlorosis) lower older leaves with darker veins. Yellowing areas will start to brown off and die from the edges of the foliage.
How to solve the problem
- 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.
Houseplants
- Ensure your houseplants do not have a magnesium deficiency by using Gro-Sure Houseplant Pump'n'Feed and/or Droplet Feeder.
- For orchids use Gro-Sure Orchid Pump'n'Feed.
- For succulents use Gro-Sure Cacti and Suuculent Pump'n'Feed.
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.
