Why are the leaves turning yellow on your newly planted Mandern tree?

The leaves of your newly planted Mandern tree may be turning yellow due to several factors, including overwatering, which can lead to root rot, or nutrient deficiencies, particularly nitrogen. Additionally, transplant shock from being moved can also cause yellowing as the tree adjusts to its new environment. It's essential to check the soil moisture and ensure the tree is receiving adequate nutrients and proper care.
