Do you have access to a sewing machine?
Tulle, sewn into small diameter tubes, can be filled with Osmocote, tied off like sausages with a long space between them, and buried.
I got that off an organic (lower case o, I think) farming site.
Why an organic grower would even know what Osmocote is... ;-)
