When did Wilfred Owen start practising writing poetry?

Wilfred Owen began writing poetry seriously around 1913. He started writing as a child, but his early work was mostly in imitation of his favorite poets.

It was during his time at Craiglockhart War Hospital, where he was recovering from shell shock, that his poetry truly took shape.

It's important to note that while he began writing poetry seriously in 1913, it was during his time in the war that his work became deeply impactful and focused on the horrors he witnessed.
