Very nice concept and idea. The design is simple and efficient. Small comments : 1. Living in Europe, the US "zip code" is bit restrictive. In other words, will you make a version for European users? 2. It would a nice idea to extend a bit to the "heritage" and open-pollinated varieties when choosing the vegetables/seeds. 3. When planting in a garden, you have to rotate the culture at a specific interval (depending of the species). Maybe a small info box where you can enter the location in your garden (like area A,B,C,D) and when the reminder is coming is informing the users where the vegetables where previously located. 4. There is also some interesting benefit to use companion planting (http://en.wikipedia.org/wiki/List_of_companion_plants http://en.wikipedia.org/wiki/List_of_companion_plants). 5. Some people are gardening and planting following the "moon phases". I don't follow the approach but that could be an option in your reminder email. Good luck for your work and startup.
