want to try to get some roots by that method of making a cut in the stem and
packing it with spagnum moss and wrapping in a polythene bag and keeping
moist until roots appear.

is there anything else i should specifically know about this technique?

also does anyone know where i can buy spagnum moss for this in north London
(u.k.) please?

I've had success with air layering fig trees using peat-free compost. I
think the important thing is that it must be something that retains
water very well.

Cling film is easier to use than a plastic bag.

Not sure what the OP wants to prop, but air layering seems too much
hassle to a lazy man like me: simple cuttings are easy enough,
especially if it's a ficus elastica.
