How to Grow a Bountiful Crop of Potatoes in a Garbage Can

As a homesteader and gardener, I’m always seeking creative ways to maximize my harvest especially when space is limited. That’s why I was intrigued when I first heard about growing potatoes in a trash can or garbage can. This simple technique allows you to produce a substantial potato crop in a small footprint. I gave it a try last season and was thrilled with the results! Read on for a complete guide to this fun and productive method.

Overview of Growing Potatoes in a Trash Can

The concept is straightforward – plant seed potato pieces in the bottom of a large garbage can or metal trash bin then gradually add compost or soil as the plants grow. The plants form tubers along the buried stems. At harvest simply lift the can up and dump out your potato bounty!

Some key advantages of this approach

  • Higher yields in less space. A 20-30 gallon container can produce 5-10 pounds of potatoes.

  • Convenient harvesting. Just tip the can over to gather your crop.

  • Good for beginners. Minimal equipment needed and easy to maintain.

  • Fun for kids. Allows hands-on learning about plant growth.

  • Portability. Trash cans can be moved if needed.

While any large container with drainage holes could work, a plastic or galvanized metal garbage can is ideal. Let’s look at how to carry out this fun method.

Step-By-Step Instructions

Follow these steps for success growing potatoes in a trash can:

Choose a Container

Select a 20-30 gallon rugged plastic or metal garbage can, or a food-grade barrel with a lid. Drill plenty of drainage holes in the bottom.

Prepare the Potatoes

Purchase certified seed potatoes. Cut them into smaller pieces containing 1-3 eyes apiece. Allow cuts to dry for 1-2 days.

Fill the Bottom

Place 6 inches of potting mix, garden soil, or straw in the bottom of the can. This will promote drainage.

Plant the Seed Potatoes

Arrange 3-5 seed potato pieces in the can, spacing them evenly and placing them cut side down. Cover with 4 inches of soil.

Let Potatoes Grow

Once plants reach about 10 inches tall, add 4 more inches of soil mix, leaving just the top leaves exposed. Repeat until the can is full.

Finish Growth

Stop adding soil once the can is full. Allow foliage to grow out the top. Water when the top few inches become dry.

Harvest Potatoes

After vines start to yellow and die back, stop watering. Allow 2 weeks for skins to toughen, then carefully tip the can over onto a tarp to collect your crop.

That’s all there is to it! With minimal effort, you can grow a significant quantity of potatoes in a compact setup.

Maximizing Your Trash Can Potato Harvest

Here are some additional tips to help your garbage can spuds thrive:

  • Place the can in full sun – potatoes need at least 6 hours of direct sunlight daily.

  • Use a quality potting mix or garden soil to fill the can as plants grow.

  • Consider lining the can’s interior with landscape fabric to prevent soil from slipping out.

  • Add a diluted, balanced fertilizer monthly for optimum nutrition.

  • Ensure consistent moisture, especially as plants start forming tubers.

  • Periodically check soil pH and maintain around 5.5-6.5 for best growth.

  • Monitor for Colorado potato beetles and other pests. Remove by hand if found.

With proper sunlight, irrigation, soil quality and pest monitoring, your trash can potato plants will yield a bountiful harvest!

Harvesting and Storing Your Crop

Once the potato vines have mostly died back, follow these steps for gathering and storing your tubers:

  • Holding over a tarp, carefully tilt the trash can to empty the contents.

  • Rake through the soil to collect all the potatoes, taking care not to pierce or bruise them.

  • Allow potatoes to dry in the sun for 2-3 hours after harvesting.

  • Gently brush off excess dirt but don’t wash them yet.

  • Cure potatoes in a dark, humid area around 60-70°F for 1-2 weeks.

  • Store cured potatoes in a cool (40-45°F), dark place for 2+ months.

  • Check periodically and use damaged ones immediately. Healthy potatoes can store for many months.

Letting potatoes properly cure and storing them properly are vital to getting the most out of your harvest. Enjoy your homegrown spuds!

Recipes and Uses for Trash Can Potatoes

Once harvested, there are endless ways to savor the delightful flavor of fresh potatoes:

  • Roast whole or diced potatoes seasoned with olive oil, garlic, and rosemary.

  • Make hearty potato soup or chowder.

  • Fry up hash browns or home fries for breakfast.

  • Bake classic potato skins loaded with cheese, bacon, and scallions.

  • Boil small new potatoes and toss in vinaigrette dressing for potato salad.

  • Grate potatoes into the batter for homemade gnocchi or potato pancakes.

With a simple trash can garden, you can easily grow plenty of potatoes to use in all your favorite recipes. The compact size, low maintenance, and high yield make this a winner!
