It has been watered properly and has morning and afternoon light. It’s behind the house. Can you help me?Attachments:

Hello. Leaf depreciation can be caused by a number of biotic and abiotic factors. Considering the period we are in, it is recommended to wait for the time of leaf fall, more specifically, it is advised to regularly collect and destroy them once they fall.
For the time being, it is recommended to use a fertilizer with a high potassium content, such as Fertilizer 0-0-40 Azet HerbstKali, 2 kg (by spreading around the tree, at a dose of 20 – 30 g/m², followed by incorporation and watering) or Primtal RS, 500 ml (by watering), according to the instructions on the labels. These fertilizers increase drought and frost resistance and improve the water balance of the plants.
Then, after the leaf fall, it is recommended to carry out the dormancy treatments. Dormancy treatments consist of applying a copper-based fungicide, such as Bouillie Bordelaise WDG, 50 g or Champ 77 WG, 20 g or Coppermax, 30 g and horticultural oil: Mospilan Oil 20 SG 10, 3 g + 50 ml or Estiuoil, 100 ml or Ovipron Top, 100 ml. More information about dormancy treatments can be found in our article: Winter treatments with oils and copper-based products.
Starting in spring, it is recommended to follow the specific care conditions described in our article: Rowan, planting guide and care work, respectively consulting specialist advice from the first signs of disease. Also, watering is advised to be done based on the recorded temperatures and rainfall, and only when the soil is dry on the surface, as the activity and spread of plant diseases are promoted by the high and constant humidity of the soil.
Furthermore, also in spring, you can consider replacing potassium-based fertilizers (Fertilizer 0-0-40 Azet HerbstKali, 2 kg or Primtal RS, 500 ml) with one specially formulated to stimulate optimal root development and thus increase plant resistance to stress factors, such as AMN Nordalge, 500 ml or Tree Shrubs, 1 litre, by watering, according to the instructions in the description of each product.
Given the current state of the rowan and those mentioned above, it is not possible to say exactly how it will develop in the future.-
