Growing Vegetables in Old Car Tires
For those in colder climates, or simply in possession of an excess of wheels, planting vegetables in old car tires can be an easy and economical way to extend your plants' lifespan. The rubber that makes up tires is notoriously long-lasting and difficult to dispose of, so not only will your gardening improve, you'll also be helping the environment!
The greatest benefit of using rubber tires is that they are fantastic insulators. The walls hold in heat and can prevent frost damage to vulnerable root systems. They are also easy to maintain and tend to, making them perfect for those with limited space or time. The chemicals used in the tires generally do not seep into the soil, making them safe for both the plants and later vegetable consumption. However, if you're concerned about these chemicals, a plastic bag stretched over the rubber will shield your soil.
How to Make a Tire Garden Bed
Tires are a perfect shape for garden beds, although they can be made more efficient with a few simple modifications. Once the tire is where you'd like it, cut off the top sidewall (the bit that curls over and obscures some interior space.) This effectively doubles your growing area. From there, fill the tire with compost and soil, and you're ready to start planting! Simple, eh? Growing in tires will require careful watering, as they dry out more quickly than regular beds, but are otherwise easy to maintain.
There are plenty of ways to get creative with tires. A sequence of increasingly smaller, stacked tires can make for a wonderful strawberry patch. The most efficient way to grow potatoes is through progressively stacking tires and soil around growing plants, thus elongating the root system and yielding an impressive amount of potatoes per square foot of garden. Tires are also an effective barrier to smaller herbivores like rabbits, and the smell of rubber may deter larger animals such as deer.
Old tractor tires are great for large beds, and can usually be found through an ad on Craigslist or at your local scrapyard. Due to their plentiful numbers, cheapness, and ease of establishment, tires are a great alternative to more traditional raised beds.
