Rooftop gardens have recently become all the rage in urban environments, making use of space that has access to sunlight and is otherwise wasted to grow delicious, nutritious food. But what if you don't have a roof?

A recent article in The New York Times highlights a developing trend: vertical farming. By creating edible walls, which are essentially panels of metal, filled with soil and seeds, you're doing more than growing food. Edible walls, like green roofs, provide insulation to the building, reducing the cost of heating and cooling. And they have one really big advantage over rooftop gardens: they're able to grow food in far less space than traditional gardens.

In the past few months, vertical farming has garnered a lot of attention for this reason. Edible walls can utilize graywater, recycling it to water plants. With vertical farming methods, you can grow plants organically, without the use of fertilizers, pesticides or herbicides. It eliminates the potential for weather-related crop failures if done indoors, and it minimizes pests and other diseases that can cause damage to plants as well. Most saliently, it allows otherwise unused space in cities to produce high-quality, organic, quintessentially local food.

While some vertical farming advocates foresee a future with skyscrapers full of high-tech edible walls growing food en masse for, well, the masses, right now the technology available is fairly simple. Simple doesn't always mean cheap, though, and The New York Times reports the cost of edible walls at "about $125 a square foot, or $500 per planted panel." Although it's an investment up front, just think about picking lettuce for a salad right off the wall of your fifth-floor walkup in the city. Sounds delicious to me.

For farmers in the Northeast, at least, this growing season was a very hard one. Incessant rains and cold weather led to late blight, and it was hard for anything to ripen without the warmth of the sun. We did have a late rally with some warmer weather and sunshine, but it wasn't in time for many small farmers, who experienced serious crop losses. This New York Times article reports that much of New York, Connecticut and New Jersey farmland has been or is being declared agricultural disaster areas this year.

Tomato and potato crops were devastated by late blight, with massive crop losses for many farms. The first cut of hay was ruined for many farmers, which spills over into the cost of keeping animals in hay over this coming winter, putting additional stresses on dairy farmers and other livestock farmers (right down to the hobby farmer feeding his one horse).

Have you ever thought back on your years of homesteading or farming and considered what you would have done differently, knowing what you know now? Or do you just wish you could fast-forward and tell your beginning farmer self all the secrets you'll undoubtedly know in twenty years?

In Homesteading Lessons Learned on Mother Earth News, Steve Maxwell lays out the wisdom he's gained after two decades of homesteading with his family. I read his tips eagerly, and found myself nodding along and jotting down a couple of notes as well.

Some of Steve's overarching themes mesh with things I've learned as I've begun my own journey: that it's best to take it slowly and build infrastructure first before gathering livestock; that raised beds can be a good thing; make your house work for you first - you have to have good shelter; a four-wheel pickup truck is a critical piece of equipment; and - my lesson most recently learned - high-speed Internet is not a luxury.

In fact, I found myself a bit more at peace with the two steps forward, one step back dance of "progress" here on my own small homestead. This year I tried to go all-out with garden space, and Mother Nature had a good laugh at my expense. Next year I'm going to refine my gardening skills in more limited square footage and focus on doing less, and doing it better.

Which of Steve Maxwell's tips are your favorites? What tips do you have for someone just starting on this adventure?
