Calcium deficiency

Editorial diagnosis

Diagnosis overview

Calcium deficiency is a deficiency pattern in which nutrient supply or uptake does not match the plant's needs.

In gardens, Calcium deficiency can occur on plants including Physalis peruviana, Apple, Eggplant, Common chicory. In the available profiles, it is linked mainly with Berries, Cabbages, Cucurbits.

The recorded risk level is medium.

Check whether young or older leaves react first, whether veins remain green, and whether the pattern is evenly distributed. Assess soil moisture, pH, and root condition at the same time. Record the most recent feeding and use a soil test for recurring or widespread deficiency patterns instead of applying several fertilisers on suspicion.

A common mistake is to fertilise immediately. Waterlogging, drought, cold soil, unsuitable pH, or damaged roots can block nutrient uptake.
