Diagnosis overview
Iron deficiency is a deficiency pattern in which nutrient supply or uptake does not match the plant's needs.
In gardens, Iron deficiency can occur on plants including Aronia, Watercress, common sage, Serviceberry. In the available profiles, it is linked mainly with Berries, Fruit, Herbs.
The recorded risk level is low.
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.

Typical signs
- Interveinal chlorosis (yellowing between leaf veins)
- often in overly calcareous soil
- usually caused by a soil pH that is too high
- Veins remain green
- In severe deficiency: leaves become almost white
- Stunted growth
- Starts on the youngest leaves
- often caused by excessively high pH
Immediate actions
- Foliar sprays with iron chelates
- Anpassung des pH-Wertes des Bodens
- Bodenverbesserung mit saurem Kompost oder Torf
- yes
- Improve soil to lower pH (if necessary)
- Application of iron chelates
- Iron chelates as foliar spray
- acidic fertilizers
Prevention
- Grow in suitable soil (slightly acidic to neutral)
- Avoid soils with high pH
- Cultivation on suitable
- Cultivating in soils with optimal pH (6.0-7.5)
- Maintain soil pH in optimal range
- Adjust soil pH
- Planting in suitable soils
- Maintain optimal soil pH
