How to build a straw bale garden, this site has more information... I did it this year and I'm amazed at the size of my tomatoes! I put them around my Rhubarb patches and I was harvesting rhubarb into late September! Give this a try
Straw-bale gardening lengthens the growing season in colder climates because the straw releases heat as it decomposes. - weed free and can use as mulch once the gardening season is done, very interesting idea! Would look cool growing pumpkins up a trellis too in the fall.
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.
