I found this neat site pinned on pinterest today -it's called "sproutrobot.com".
Enter your zipcode and it will tell you when you should be starting your vegetables. You pick the crops you plan on growing and it generates a planting schedule for you. It'll even send you email reminders telling you when you should be planting each vegetable. It has instructions on how to plant as well.
I think this will be very handy considering I'll be growing in a whole new environment this year. I thought this was just too good not to share!
