At FoodCon I met two of the people behind the innovative Bloomington-based Garden Tower Project. Check out their garden-in-a-barrel design with built-in worm composting. Up to 50 plants can be planted in this unique vertical garden.
The center tube is perforated down the entire length, allowing red wiggler worms to travel between the compost tube and the soil. Kitchen waste goes into the center tube and turns into compost and worm castings. Bonus: The protection of the soil in the barrel means the worms can survive through the winter.
“In an era of rapidly rising food prices and industrial farming practices that strip our food of nutrients essential for good health, we believe the Garden Tower is one small step in empowering people towards their own food security.”

Tom Tlusty tells me that the Garden Tower’s unique design capitalizes on “evaporative cooling and a large thermal mass”–making it possible to plant in hot temperatures normally prohibitive in a traditional garden plot.
So… it’s not too late to start gardening this season!
I’m so excited about this design that I ordered my own Garden Tower, and I’m picking it up from the Good Earth later today. I’m psyched to sow some crops I didn’t have room for, like beans and carrots. I’ll also scour local garden centers for leftover seedlings (probably quite sad and stressed by now, but maybe a little TLC would bring them along).
It’s nearly time to start fall crops, like kale, lettuce, peas, and spinach. That’s something I always intend to do and never seem to manage in the thick of late summer. But this is the year, with my sweet new protected microclimate as incentive.
Plus I’ll finally have livestock on my homestead, if only in the form of worms. I’m in heaven!
The only drawback I can see is the need for potting soil to ensure that the growing medium is not compacted in the barrel. I hate buying bagged soil for so many reasons. I’ve seen recipes for homemade potting soil. But being eager to jump in, I probably will break down and purchase. (If you’ve found a good peat-free variety available on the market, please leave it in the comments.)
The inventors believe their design will allow people of all abilities to garden in any clime. According to Garden Tower users in the arid Grand Canyon region, this model results in immense water savings. Tom says they used ten times less water with the Garden Tower than their traditional plot or raised bed.
Really can’t wait to dig in!
