Truthfully a lot of that last frost and zoning information is a bit over my head. So I had to look it up quickly. According to the book Incredible Vegetables from Self-Watering Containers, New York City is in Zone 7 and the last frost date is sometime in mid-April. The map and legend were hard to decipher. In the video, I erroneously say Zone 8 and mid-May. Genius idea to color code a map and put similar colors side by side. I also checked out a bunch of sites online and the only one that was somewhat coherent was the What to Plant Now...
