Below I have created a Year Round Gardening Chart based on the Seeds I currently have in my inventory. A couple days ago I posted Garden Calendar for ALL USDA ZONES 1-11 (When to grow different vegetables & Moon phases) which provided a short list of vegetables to grow by month. In the chart below is a more extensive list of Vegetables to grow by month. Please refer to Garden calendar post for your personal growing Zone/season/times.
Seen in the chart below, March through May will be dedicated to growing Greens outdoors and harvesting May through July. In May I will be transplanting Tomatoes, Peppers, Eggplant outdoors, as well as growing Corn, beans, cucumbers, and Squash. In late Summer I will start Cabbage, Brussels, etc for a Fall and Winter harvest.
Not seen in the chart below, January through April I will starting Fruits and vegetables indoors, which I have discussed here: Mini Greenhouse, What plants to start indoors, & growing sub tropicals in cold climate.
If you're interested, I purchased the seeds in a "seed vault" from Vegan seeds company on amazon. Some of other seeds like Acorn squash and spaghetti squash, were saved from store bought fruit. The luffa and Goji berry seeds were bought from the companies I mention in this post, as well as links to Vegan seed company: Seeds I bought for 2015 Garden year.

Year round gardening is possible in warmer climates. Southern Florida has such mild Winters, FL gardeners are able to grow Tomatoes around this time!
For gardeners in cold climates--like myself--Greenhouses, cold frames, poly tunnels, or any covering apparatus is needed to trap heat and moisture for the plants during the Winter. Greens and root crops can withstand cool temperatures but once the temperatures drop to 0 degrees, your plants may die unless if they are covered with a cold frame (seen in the picture above).
Of course I recently bought a Mini Greenhouse which will allow me to start fruits and vegetables early. But the Greenhouse won't cover my crops in the outside gardens, so I will need to make Poly tunnels for starting Greens and root crops early in the Spring Garden. Cold frames will be implemented in the Fall and winter months when growing Greens and root crops.
Constructing Cold Frames, Poly tunnels, and other coverings will be a topic for a future post. If you're interested, I have an existing post on how to build a greenhouse for free or little money using little materials which will give you an idea of how to build other coverings (Plant protectors), here: Construct a Greenhouse using Free Materials.
