I was surfing iTunes looking to see if any new gardening podcasts had started and I found one that is actually really good!
It’s the Alternative Kitchen Garden. The associated blog is fluffymuppet.blogspot.com
The author’s name is Emma, and she lives in the UK. She basically talks about whatever topic she’s interested that day. Much like MyChicagoGarden but less structured and more sociable 
I highly recommend you check it out and give it a listen.
Episode 10 for MyChicagoGarden should be posted tonight…sorry for the delay.
