I’m going to buy seeds this weekend. If you have any special requests, let me know. Things that are good to plant in September are: greens (mustard, collard, lettuces, mizuna etc), broccoli, cabbage, arugula, radishes…Here is a more complete list: ANR_planting_calendar. Look in the “September” column. Also, make sure that the “approx days to harvest” will let you get your hands on your finished product by the end of the semester. Celery, for instance, takes “130-140 days.”
You can also look in the links at Kitazawa Seeds for Asian, not just Japanese, vegetables. And at Peaceful Valley (also in the links) for all kinds of stuff. If you have a request, put it in the “comment” section.
