Product performance:
Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth.
Magnesium is necessary for functioning of plant enzymes to produce carbohydrates, sugars and fats.
Magnesium is used for fruit and nut formation and essential for germination of seeds.
Deficient plants appear chlorotic, show yellowing between veins of older leaves; leaves may droop. Magnesium is leached by watering and must be supplied when feeding. It can be applied as a foliar spray to correct deficiencies.
