Try an Armstrong's Garden Center Nursery near you. They used to take in recycled/used pots. That's how I got mine for moving my cannas 2 years ago in Pasadena. Or any nursery.

Are any schools near you involved in a 'green up' type program where they are trying to pretty up the yard and plant some flowers and shrubs and trees? Maybe they have some teachers who are trying to teach about seeds/growing etc and would appreciate some pots (and maybe some free seeds and maybe even someone to come in and spend an afternoon a week teaching about gardening in a "gardening club"). I know our school asked for some divisions to use in the new gardens. I sent mine in a plastic bag, but if they had sent a pot or two home with DGD, it wouldn't have been so messy. :)

I use 2/3 perlite, 1/3 or less peat moss. I dampen it and use plastic water bottles, drill or punch big round holes in the bottom and a few on the sides 1-2" from the bottom. I don't cut much off of the top of the water bottles because I don't want too much water to get in if it rains. Then I wedge styrofoam in the top to secure them and to further block water from entering. I sit them in the hottest place I can find, usually the driveway or on top of Pinebark in a bed by the driveway, in full sun most of the day. I think the clear containers help them root faster. I've tried using eggs in them, honestly didn't notice any difference. I did 2 Singapores, one with the egg, one without, they rooted at the same time and roots were the same size. Both cuttings from the same tree. If we get lots of rain and I think they are too wet, I bring them inside in the air conditioning and let them go bone dry before I put them back in the sun and heat. If you don't want to worry about them getting too wet, just use perlite alone. That works fine too. Also course builders sand but if you use the sand be careful when you cut the bottle and take them out, the sand is heavy and can break the roots. Rinse the sand away, then lift them out. That's what has worked best for me here in zone 11.
