Experiment: Sweet Potatoes in Containers

The experiment has officially begun! I have read nothing on growing sweet potatoes in containers. So, aside from what I know about growing them in general --- I'm on my own.

Sweet potatoes are grown from the "slips" or sprouts that appear after you've held onto them too long. I had a few potatoes from the winter, that had taken on lives of their own. Pre-sprouted, even. I also stuck a couple in jars, submerging the ends in water, held in place by toothpicks. Sounds a lot like the low-tech science experiments done in grade school, doesn't it?

When the slips are about 8" long, they are ready to be removed, with a twisting motion and planted. Another shortcut I have taken is to stick the slips in an organic potting medium, so that they can develop a good root system.

Apparently, sweet potatoes do well in a slightly acidic, loamy, sandy soil that is rich in organic matter. Too much nitrogen with produce rampant vines and distorted tubers. A cupful of organic liquid fertilizer per plant, rich in phosphorus will get them off to a good start. One specifically for transplanting should do the trick.

The sweet potato slips have to be kept well-watered to keep them from withering. Sweet potato plants need at least 1" of water per week. Then the amount of water can be decreased as maturity approaches, in order to keep the tubers from cracking.

What I wouldn't do for a home grown tomato right about now! However, these things take time as anyone who has grown them knows.

Tomato plants like it warm, and the weather has only been mild so far this spring. I haven't grown tomatoes in over 30 years, and I'm excited. This year, I am growing five different varieties of them. The peppers don't excite me as much, but they're pretty cool, too.

As the weather gets warmer I'll add Asparagus Beans, sweet potatoes and cucumbers. I can hardly wait...

Jalapeno and Bell pepper plants.

Growing What I Eat - Container Gardening vs. Traditional

Behind the house.

The "main" garden space as of May 7th, 2009.

I live on the south end of a major urban area. I decided last summer to make the transition from indoor gardener to enhancing my hard scape and growing outdoors.

I actually have a decent-sized backyard, with plenty of space for all types of gardening. So, why did I choose to garden in containers? It made sense for a variety of reasons:

• Gardening tasks are easier because I'm working in a small space. Preparing my planting area was a matter of filling containers with pre-mixed soil. I can use hand tools (such as a trowel), as opposed to a spade or rototiller (which I didn't have the money to rent, or the muscle to use). Checking for signs of insect or other pest damage is easier, because the plants are right at hand. Also, preventative measures are easier to undertake because of the smaller number of plants.

• One exception to easier gardening tasks is watering. With a traditional garden, you can just set up a sprinkler system. On the other hand, going back and forth with a watering can may end up being a pain in the ass. Containers do dry out faster than gardening beds. My solution: I located my main set of containers right next to an outdoor tap. It advantageously happened to be the sunniest area on the property.

• Containers are mobile. They can be moved around, grouped and regrouped to suit your personal tastes, offer convenience and be moved with changing growing conditions as the seasons evolve.

• I will most likely not have to deal with soil-borne illnesses. Such things can persist in soil for years and be almost impossible to eradicate.

• Container gardens hardly ever have weeds.

Container gardening is a great option for the many city dwellers whose gardening space may consist of a porch, deck or patio. Even for those with an existing garden space, placing containers near the kitchen or around the outdoor grill may add versatility and convenience.
