I know I looked it up awhile back but didn't really come up with anything "easy" to do
most of what I found was property owners needing to contact agencies.
Seems like there could be an advanced canvassing of neighborhoods.
"in 2 weeks on Jan 17th our volunteers will be in your neighborhood to pick citrus ...blah blah blah....
place this sign [ribbon - whatever] on any tree you'd like us to pick and take to the blahblahblah food bank."
People don't reach out for help - nobody has the spoons.
