What is Cal-Mag’s Key Role in the Garden?
Calcium, an essential part of the plant’s cell wall structure, improves the absorption of other nutrients by the roots and their translocation within the plant, and contributes to improved disease resistance.
Calcium deficiencies
- Calcium deficiency symptoms appear initially as generally stunted plant growth. Cupping of mature leaves is a tell tale sign of a calcium defiency.
- Classic symptoms of a calcium deficiency include blossom-end rot of tomato (death of the end part of the fruits), tip burn of lettuce, blackheart of celery and death of the growing regions in many plants.
Magnesium Deficiencies
- Deficiencies typically occur with the middle or lower leaves. The most common symptoms are interveinal chlorosis or yellowing leaf veins, which stay green, giving a marbles appearance.
- Calcium and magnesium are found in most plant nutrients. They are also available combined into one bottle as a supplement.
