Cherry Blossom Tree

Hi there.

Apart from the conifers I had lopped, they also very heavily pruned a
cherry blossom tree. There are just the main scaffold branches. Looks
quite ugly, whereas it was beautiful but overbearing before.

Do you know how long a heavily pruned cherry blossom tree will take to
come back. I'd just like to see some green on it again. I didn't think
it was going to be pruned so harshly.
