Help: Salix Integra (Flamingo Willow) Tree looks like it is dying
So, firstly I am extremely new to gardening and only started this year once I got a Bonsai kit and then ventured into what else we can grow and then then this spread to the garden.
Myself and the wife purchased the Salix Integra tree to be potted in our front garden area as the previous palm which was left from previous tenants was dead so wanted something new.
The garden is south facing at the front of our garden and we planted it around April time this year (2020). It was doing well throughout the summer but lately is starting to get brown crusty leaves which are falling off and also some of the branches are starting to look brittle. I have seen mixed messages online saying we should let it develop for the first year but I am worried if we do nothing to it, it will die before next Spring.
I am wondering if it is because it is getting later in the year and also whether we need to move it for winter also.
Any advice would be great and please see attached picture, can attach more if needed.
Thanks in advance.
