A few months ago I bought a japanese maple dissectum. I repotted it. I never knew what was the right place to put it and I accidentally put it in a very sunny and windy position. It's leaves dried out in a few days and they all fell off. I moved it to shade and not windy. No knew leaves have grown back yet and it has been three months. The tree is alive because I scratched the bark and it is green. Will they grow back?
