Using one of those 'claw' type rakes we have just tidied the garden and now

Is there any reason not to use such tidyings in the 'bottom' of garden pots
to reduce the amount of soil and compost needed to be used in the pots? The
pots will be for outdoor plants in the garden.

Yes, I have done so. You can also use the moss thatch from lawns to
line hanging baskets.
If there are seeding weeds, I'd not use tham, though buried deep in a
big pot, you shouldn't have a problem.
