Growing your own food doesn't have to be an expensive activity. There are plenty of ways to cut back the costs and be earth-friendly as well. You can do this by giving a second life to items that have outgrown their initial purpose.
One such item that you can find in abundance and use in your garden is a soda bottle. Even if you don't drink soda, you can find these everywhere or ask family and friends to save them for you.
According to Earth911.com: "Less than 1 percent of all plastics is recycled. Therefore, almost all plastics are incinerated or end up in landfill."
By cutting off the top of a soda bottle, you can add soil and carrots seeds. You won't have huge yield, but you can get a few carrots from a very tiny space. It is certainly possible.
This is a project that I did when I was living in New York City and gardening on my fire escape. I was able to line the railings of my fire escape with about 10 of these and grew herbs in them. It's a great project to work on with kids because you can decorate the soda bottles together.
All you'll need to create one of these is a soda bottle, old t-shirt and newspaper. They are smaller versions of self-watering containers, but just as effective for more shallow roots veggies.
Those are just three ways that you can cut the costs of gardening, start your own and do it all in an eco-friendly fashion.
