Large grow bags — essentially “instant” raised beds — are easy, ready-to-fill planters that have some great benefits for the urban garden. They’re easy to transport, since they fold up compactly, and plants thrive in them.
Our former residence—a large lot in town—was steep and shady.
It was not conducive to gardening at all and certainly not a place where we could plant a nice level garden without a whole bunch of work and wall building. I tucked plants into every sunny spot available in my initial attempt at urban gardening, but I was just not content with that. I wanted to GROW THINGS!
The only really sunny spot in the yard was the driveway. And let’s face it: A garden is much more important than having a place to park! (No, really. There were other places to park. Though there might have been a little bit of eye-rolling by some of the other drivers in the household.)
Raised beds on the concrete made perfect sense to me, so I started exploring my options for a creative urban garden. I made a few beds out of banana stumps, and those worked fine but we just weren’t harvesting bananas fast enough to create as many beds as I wanted. Plus, they were destined for the compost pile after just one season.

I debated using wood, but knew they’d rot relatively quickly in our humid climate — and that they’d be expensive. But I ended up going in a totally different direction. I got three large grow bags, filled them with good soil, and went to town planting seeds. [My grow bags are SmartPot brand.]
And look! They worked beautifully. After fighting our limitations for a couple of years, I finally had a very successful—if small—crop from my driveway garden.
The biggest question I’ve had from people is about the material of the grow bags. The grow bags are made of a BPA-free fabric. And the porosity of the fabric allows for air root pruning. Which is kind of a fancy way of saying that plants grown in these pots don’t get root bound like plants grown in hard-sided containers.

Grow bags can tend to slouch a bit over time, as you can see. I’m into my third year with these pots, though, and they’re still holding up well. While I opted for large pots, grow bags come in a variety of sizes. The smaller ones would be great for apartment dwellers or those with limited space for growing food.
