Cherry Yoshino Fungus?
I recently planted a more mature Cherry Yoshino (15-20 ft tall) a few weeks ago. I noticed last week that a handful of leaves were turning yellow and falling off. After inspecting the tree/leaves and doing a little bit of research, it looks like the tree had a fungus (shot hole).
Here's a picture of one of the more healthier leaves with a spot on it.
After speaking to the nursery I bought the tree from, they gave me a systemic fungicide to spray on the tree. It's only been a few days since spraying but the amount of leaves falling has increased dramatically. I still see a lot of healthy leaves near the top of the tree and I've been monitoring the healthier leaves near the bottom to see if any spots/turning yellow starts happening.
Is there anything else I can do to save the tree? If so many leaves end up turning yellow and falling off before summer will it just be SOL until next spring when it blooms again and regenerates new leaves?
