Looking For A Greengrocer...
When I was a kid, one of our local news broadcasts had a segment called "The Greengrocer". He would just talk for a minute or two about the produce currently available, what was good, what was in short supply for whatever reason, and sometimes he'd have advice about what to do with less common varieties. I started looking for a website that would give me similar information...what is available where in cheap abundance. I was surprised when I couldn't find anything. I don't just mean lists of what should be available where and when because as crazy as weather has been the last decade or so, those lists aren't really reliable anymore. Does anyone have any favorite places to get current produce information?
For local produce availability, http://www.pickyourown.org/ - just click on your state.
Local news channels sometime have a regular produce segment. In the NY Tristate area, it's Produce Pete on the local NBC station.
ETA: From his website - he does a segment on WCAU Channel 10 in Philadelphia, every Sunday and Wednesday.
Google seasonality charts for your area and you'll come up with helpful sites like the ones below.
