Hi- I know it is kind of late in the season, but I just ran across this thread again. For people that are looking for organic potting soil, I would recommend Promix, which I pick up at Menard's in Morton Grove, although I am sure most of the other Menard's carries it. I use it to plant my herbs and flowers on my condo balcony. A lot of people ove on Gardenweb just rave about this stuff, and that is how I learned about it.
As far as nursery's go, my favorite is Anton's in Evanston, which has been in business for over 60 yearrs. They have tons of veggie plants, including many heirloom tomato plants. Starting in the beginning of August they sell some fall veggie plants that they have started in the greenhouse. They usually have collards, broccoli, lettuce, and some other greens. Most of what Gary Anton cannot raise himself, he gets from his brother that has a huge greenhouse somewhere in Southern Wisconsin, near Kenosha I believe. The staff in general is really knowledgeable, and especially Gary. The only time the person helping me out, could not answer my question, was when I was asking her about hot peppers. I wanted to know how hot a particular variety was. She ended up asking one of the Mexicans that works there, and they were able to tell me. They are way more knowledgeable, and way cheaper than Home Depot on Oakton. When I was in Home Depot around a month ago, I saw a woman with a tomato plant in her hand that she was thinking about buying, and it was $14.95. I went up to her and told her about Anton's, which she had never heard of. I said that their tomato plants were way cheaper than that. Before I approached her, she was considering asking if HD would sell her the plant for 1/2 price, which would still be too much money, because it was not in really good condition. She was not familiar with Evanston, and so I don't know if she found Anton's. It is kind of hidden. I see people buying tomato plants all the time at HD, and I just want to scream.
I got a few organic plants at the Evanston farmer's market back in May from Terrra Brockman too. She has really good stuff, but she is not cheap. She charges $6 per plant, and I wait until she marks it down to B1G1F before I buy anything from her. I also got some cinnamon basil plants from John First for $1 a plant. They are 4" pots. He still had some for sale last Saturday.
Finally it is not organic, but the Jewel on Chicago Avenue still has a ton of mushroom compost, manure, top soil and potting soil for $1 a bag. I believe most of the bags are 40 pounds. The mushroom compost was originally $3.99. Last time I was there on Tuesday, they had at least 50 bags of mushroom compost left, and even more manure. The Jewel on Green Bay in WIlmette is still selling their mushroom compost for $3.99 a bag.
