One of our goals this summer is to grow a vegetable garden on our porch. Last year we tried using the raised beds already in our yard, but a combination of knowing nothing about vegetable gardens, being overly ambitious with the crop selection, and a crazy amount of weeds amounted to few successful vegetables. We also had quite a few moles, slugs, and a cat that liked to use the beds for a litter box. It's still snowing in the Cascades and my horticulture guru says he doesn't plant until May, but I can't help but dream of the organic fruits of my labor. Also, some of our crops can be started in the greenhouses soon. Here is a link to what you can start planting and prepping in your garden.
Here are a few other pages I have found that I will be reading up on:

We plan to build rectangular planter boxes for the porch out of some scrap lumber so project photos will follow when the day comes. Until then I will be researching crops, hunting for good planter box designs, and praying for sunshine.
