Nurseries
Potted plants with frequent watering.
Community gardens

Why magnesium
Magnesium, at the center of the green leaf
Magnesium is part of chlorophyll, the pigment that gives leaves their green color and through which the plant utilizes light. Woody crops and demanding horticultural crops deplete it season after season, and when it is lacking, yellowing appears between the veins of the older leaves.
Crops
Where else it is noticeable
Olive trees
Helps keep the leaf green and active, especially in light or sandy soils.
Vines
Corrects yellowing or reddening between the veins of lower leaves.
Citrus and fruit trees
Apples, pears, stone fruits, and citrus trees in production.
Horticultural crops
Tomatoes, peppers, and other demanding solanaceous crops.
We explain it in detail in our article about magnesium sulfate for pome fruits.
