Hey friend,
I think i would opt for leaving whats growing there just to have something living and growing. I know people will plant "cover crops" in their off seasons like barley, rye, oats etc. And maybe that could be a good option for your next growing season?
*some people will use rye grass because it helps to control the weeds and then till it into the ground.
My favorite podcast talks a lot about myco and has some very good guest who are pretty knowledgeable like jeff lowenfels (he wrote teaming with microbes). Its called the cannabis cultivation and science podcast by kisorganics.com maybe give it a listen if your ears had some free time.
Happy growing.
