Straw Bale Gardening is great if your soil is poor or even non-existent (or if you can't be bothered to build raised beds). Follow along as the Root Simple blog gives this simple gardening technique a try.
We use two tomato plants per bale with marigold plants tucked in pockets in sides of bales. The flowers will warn you when the bales are too dry inside. Also we use jute twine so it can go directly into compost next year. Straw gets spread as mulch for winter.
In case you're wondering what to plant in your garden next year, here is a cool chart with lots of companion planting tips! Too bad raspberries aren't on here, but they did really well this year with my tomatoes and cucumbers.
