14 Survival Garden Crops You Should Plant in August

Survival gardening is a great way to bolster food security and self-reliance. If you like to stay ahead of potential emergencies or food supply shortages, it’s practical. It can also offer substantial cost savings as the price of food and produce, in particular, continues to rise. 

In a world where there are few absolute certainties, self-reliance is something we should all move toward. While it may never become an absolute necessity, a survival garden has many benefits. It reduces the grocery bill, provides the freshest produce, and creates independence and resilience. 

In August, as the summer harvest is nearing its end, it’s time to start planning for the cooler months. By planting cool-weather crops now, you can have fresh, flavorful vegetables in fall and winter. Good August survival garden crops include those with excellent storage potential, those that mature quickly, and those that endure frost well.
