First, you need to establish how much space you have to plant. If you have no ground space, you can always plant a few things in containers. You can plant tomatoes, beans, peppers, lettuce, greens, etc...there is really no end to what you can do in containers.
Next, based on your climate area, decide when you can plant and what varieties you can plant. Click HERE to find your garden zone. Based on your zone, you can then select varieties of vegetables to try out. Once you get those 2 things accomplished, you can draw it out on paper if you'd like, or enter it into a computer program. I personally just use paper, its easier and less messy trying to take a computer outside to update it.
So this year, we may decide to plant in rectangles instead of rows. I'm not positive yet if we will try this but its on the list for now. So far this is the seed list for 2013:
I'm sure there will be things added here but this is about it for now. I am also going to be trying out some heirloom tomatoes, and jalapenos in my greenhouse. I will probably add more to that list as well. Get to planning! Soon it will be time to prepare the soil!
