There is a quick and easy way to get your survival garden started--purchase a "survival garden" seed assortment. But before you buy that prepackaged bucket of seeds, you'll need to check if there are there enough high-calorie plants included. Those buckets always seem to lack some of the easy growing, high-value crops that are grown from live material, such as potatoes and sweet potatoes. Rather than buying a turnkey bucket of seeds, you might be better off selecting your own seed, supplemented each spring with slips and seedlings for each plant type. This way, you can take into account the soil, weather, pests, and rainfall where you live.
