Survival Gardening

So Mike and I sometimes watch that show "Doomsday Preppers" about people who believe some sort of catastrophe or apocalypse is imminent and are hardcore preparing for it. Some of the people in the show are a little ... intense, but it's still a good watch.
I'll admit that, as someone whose generation has been overloaded with apocalypse fiction, there is something sort of fun and appealing about the show. So in that vein, here's some basic information on survival gardening. Because you need something to eat in between shooting zombies in the head.

Don't act like you're surprised I own this.

People who are really into this will often live out in the country and practice homesteading. They have acres of space for gardening and raising livestock. People like me who live in apartments don't have that luxury. Ignoring the fact that during the zombie apocalypse my relatively high-population neighborhood will be so overrun by the undead that I'll have to flee, having a little bit of fresh food can supplement the year's supply of canned goods we all keep on hand (you all do that, right?).

Things to keep in mind for survival gardening:

• Keep in mind your nutritional needs. You'll want a wide variety of plants with different health benefits and different tastes to keep you happy. I'm thinking I'd want beans for protein, root vegetables like potatoes and carrots, tomatoes, leafy greens and herbs just to start. Broccoli provides fiber and spinach is a source of iron.You should also consider some fruit, even if it's just a couple of little strawberry plants. Also keep in mind that you will have to provide for everyone in the household, so if you raise chickens for the eggs (a lifetime goal of mine regardless of the zombie apocalypse) you will need to grow some sort of grain for them. I'm still trying to figure out how to grow dog food, but in the meantime I'll just stock up on Science Diet.
• Be sustainable. If society takes a few years to rebound from the hoard of zombies stalking the earth, you won't want to rely on getting new annuals from your local plant nursery. Plant some perennials, for a start. Also, learn how to grow plants from parts of your existing plant. You can grow potatoes and onions from leftovers that you didn't eat, and you can sprout tomato seeds if you save them. 
• Learn about preserving food to make it through the harsh winter. You can dry and can your harvest, and also grow winter crops to keep your food source coming. 
• Consider your climate. If a lot of the food you grow is well suited to your climate, you will have more success and have to water it less often. I live in Florida (which I believe the experts consider part of Zone "Help, my hair is on fire") so I would have more luck growing an orange tree than an apple tree. 
• Don't forget your rain barrel. You'll want to boil the water before you drink it, but it will also come in handy for watering your plants.

I hope this overview of survival gardening has been enlightening and entertaining. Stay safe out there and don't forget: You can only kill a zombie by destroying the brain.
