I've been doing SFG in raised beds for a couple of years now, and
there is now an accumulation of left over roots in the beds from past
plantings. I imagine they compost at some time, but do they compost
quickly in the beds? Is it OK to leave the old roots in the beds or
are they going to hinder roots/plants of future plantings?

Thanks.

The old roots will be fine. They will break down, worms will eat them etc,
pull out any that are obvious before you replant but generally don't worry.

Who or what is SFG?
