Hello, in order to help you with a recommendation, please give us more details: when did the symptoms start? Have you applied any treatment/fertilizer recently? How is watering performed, at what interval? What were the temperatures in the area?
ClClaudia7 April 2022Hello. I applied fertilizer last year and haven’t applied it since. We have had the plants for about 3 years and the symptoms appeared about a month after the end of winter, the temperatures were somewhere around -16. We don’t water often, but lately, it has been rainy and the soil is a bit wet.

In the last attached photos, the discoloration seems to indicate an iron deficiency, therefore, it is recommended to apply a fertilizer with high iron-chelate content, such as  AMN Optiferrum, 500 ml, by spraying, in a dose of 10 ml/1 L water. 3-4 treatments can be carried out at an interval of 1-4 weeks. Also, to ensure the necessary nutrients, it is recommended to use a granular fertilizer specially formulated for the nutritional requirements of rhododendron such as Rhododendron, 1 kg. At the same time, it is advisable to keep a small portion without grass around them.
