Free? You could check the local land fill, I've gotten composted leaves from one but you can't count on it being organic, it's just leaves and maybe grass clippings. I used to be able to get free mushroom compost (from the plant across the road which no long exists) and free horse manure by just cleaning out a stall or two. Lately, most places want to sell the stuff. Good luck with your search.

Mark, Any luck with the compost? I am in Tarrytown and I too am starting a Square Foot Garden.

Best to answer your own questions around here, apparently. On May 16 they will be giving away compost and selling compost bins at cost for $20 and $40.

If anyone had the answer, it would have been posted, obviously. As I am in Dutchess county, I don't keep track much of what goes on in southern Westchester or north Bronx. Thanks for providing the update.

I think that is last year... the date says WED MAY 16th
that is last year's date.

i am writing to find out what the new date is.

I couldn't find the location of the farm, but I suppose members of the site have access to such information.
