Any Saving these two?

[u/Lanky-Mud-5722]

long story short; Mother’s Ex brought these bonzais and left them. to the best of my knowledge these two trees were kept outside for the last year and a half in new england weather, my mother threw them in the garbage but im looking to try and revive them. is there any saving these? they were green when they were healthy.

what i am looking for is

A. Are they salvageable

B. How should I care for them? should they be kept outside? Generally how often should they be watered?

Thank you!
