I just came across this website, Sprout Robot, via Pinterest and I think it's the coolest thing since sliced bread. Being the amateur gardener that I am, I'm never quite sure when I should start planting my seeds. On this website, you type in your zip code, and it tells you what to plant when! How cool is that? Obviously I think it's pretty darn cool.
Since I grew four 50 lb pumpkins last year, I must have done something right. But eventually my beginners luck will run out and I will need some actual knowledge to back me up. So this is a great start!
