Here is a handy online garden planner suggested by one of our readers! They offer a free trial, and then it does cost about $25 to subscribe - but it looks like it's very useful and worth it if you want a handy online planting guide, reminder emails about when to plant each vegetable and herb, garden planning tools, crop rotation lists, planning ahead for next year, etc. For those who like to do their garden planning in an organized manner on the computer, this looks like a great tool for you.
