Engage in gardening...,

[Silverobama]

I wrote a letter to a psychiatrist about how I could improve my state of mental health besides taking medicine. He replied "Engage in gardening is a great contributor to better mental health; have you ever tried it?" Is my translation natural?

No, it's not natural. I would write it as follows:
Engage in Gardening is a great contributor to better beneficial for mental health; have you ever tried it?

I would add "because it is therapeutic" after "mental health".
