Here is some background information:
- The ginkgo was planted this year in spring.
- We are located in Trois-Rivières (Zone 5a) with full sun exposure
- The soil is a mixture of sand and clay.
Since mid-August, the Ginkgo Biloba has started to take on a yellowish hue and the leaves appear to be slightly curling. We have not been watering extensively due to the rainfall this summer, as we want to avoid root rot.
There are other Ginkgo trees in my neighborhood, including one troll and one regular species, which appear to be greener but more mature.
Using a moisture meter, it indicates a moderate level of moisture, but I am not able to probe more than a foot into the ground.
The leaves feel somewhat dried, leading me to suspect that the tree might be underwatered. Additionally, considering it's almost September, could the gradual change in color since mid-August be attributed to temperature variations?
Is there a reliable way to differentiate whether the tree is underwatered, overwatered, or if the color change is merely a natural response to temperature shifts?
Here are some pictures below to help ! Thank you!
